Lion's Mane Benefits: Brain & Body Effects (2026)

Q: What does Lion's Mane do for your brain?

Lion's Mane contains hericenones and erinacines — compounds that stimulate Nerve Growth Factor (NGF) production. NGF supports the growth, maintenance, and repair of neurons. In human trials, daily Lion's Mane intake at 1,000–3,200 mg has been associated with improved cognitive function, memory, and reduced brain fog over 4–49 weeks of use.

Q: Why does your product contain mycelium if mycelium products are bad?

The problem isn't mycelium itself — it's mycelium grown on grain and never separated from it (the "mycelium on grain" issue), resulting in products that are 40–60% starch. Our mycelium is processed separately from its growth substrate. The final powder is mushroom material, not a grain composite. Erinacines — one of the two NGF-stimulating compound classes — are concentrated in the mycelium, so excluding mycelium entirely would mean losing half the bioactive profile.

Lion's Mane Benefits: What This Mushroom Does for Your Brain and Body

⚡ QUICK ANSWER

Lion's Mane is the only mushroom shown to stimulate Nerve Growth Factor, the protein the brain uses to grow and repair neurons. Its hericenones and erinacines drive this, with cognitive trials running 3,000 mg/day.

Two compound families drive this: hericenones from the fruiting body and erinacines from the mycelium, and Mori's 2009 trial found 3,000 mg/day improved cognitive scores in older adults over 16 weeks. It carries two compound classes no other mushroom has: hericenones (fruiting body) and erinacines (mycelium). Three human RCTs back it up: Mori et al. (2009) improved cognitive scores in older adults at 3,000 mg/day over 16 weeks (gains reversed after stopping); Saitsu et al. (2019) confirmed benefits in healthy middle-aged adults at 3.2 g/day; and Docherty et al. (2023) found faster Stroop reaction time within 60 minutes of a single 1.8 g dose. (PubMed) It's not a stimulant, effects build over 2–8 weeks. Clinical doses run 1,000–3,200 mg/day. Choose whole-mushroom powder (fruiting body + mycelium), and avoid mycelium-on-grain products (40–60% starch filler). This guide covers everything you need to know about lions mane benefits, based on published clinical evidence.

This fungal compound (Hericium erinaceus) doesn't get its reputation from marketing. It gets it from a very specific biological claim that almost no other natural compound can make: it stimulates Nerve Growth Factor in the human brain. Not in a speculative, "traditional-use-suggests" kind of way, in a "double-blind, placebo-controlled, published-in-a-peer-reviewed-journal" kind of way.

That distinction matters, because the supplement industry is full of ingredients that sound impressive and dissolve under scrutiny. Lion's Mane has survived scrutiny. The question isn't whether it does something. The question is how much it does, at what dose, and for whom.

This guide covers what the clinical evidence actually shows, where it's still thin, and how our product fits into the picture. We sell a It supplement, so we have a commercial interest in this mushroom. We'll be transparent about that and about what the science does and doesn't support.

Lion's Mane Benefits: What makes Lion's Mane different from other mushroom supplements

Most functional mushrooms — Reishi, Chaga, Turkey Tail, Cordyceps, are valued for their polysaccharides and beta-glucans, which modulate immune function and provide antioxidant activity. Lion's Mane does that too, but it also does something none of the others do.

It contains two classes of compounds unique to the species:

Hericenones, concentrated in the fruiting body (the visible mushroom)
Erinacines — concentrated in the mycelium (the root-like network)

Both compound classes have been demonstrated in cell-culture and animal studies to cross the blood-brain barrier and stimulate synthesis of Nerve Growth Factor (NGF), a protein your brain uses to grow, maintain, and repair neurons.^[1] NGF is not a minor player. It's essential for the survival of cholinergic neurons in the basal forebrain, the region most affected in age-related cognitive decline and Alzheimer's disease.

This is why Lion's Mane gets talked about differently than, say, Reishi or Cordyceps. Reishi is an adaptogen. Cordyceps supports energy metabolism. The mushroom extract touches the actual structural wiring of your brain. Different category of claim, different level of evidence required — and so far, the evidence has held up.

What the human clinical trials show

Karen D. Sullivan, PhD, ABPP, a board-certified neuropsychologist, notes that while lion's mane shows intriguing potential for nerve growth factor stimulation in laboratory and early clinical studies, the human evidence is still preliminary, and she advises treating it as a promising area of research rather than a proven cognitive treatment (I Care For Your Brain, 2024).

The published human evidence on Lion's Mane is still small in absolute number of trials but consistent in direction. Here's what exists as of early 2026:

Mori et al., 2009, the landmark trial

Published in Phytotherapy Research. Thirty older Japanese adults (50–80 years old) with mild cognitive impairment were randomized to 3,000 mg/day of Lion's Mane dry powder or placebo for 16 weeks. The design was double-blind and placebo-controlled, the gold standard.

The Lion's Mane group improved significantly on the Revised Hasegawa Dementia Scale at weeks 8, 12, and 16. When supplementation stopped, scores declined by week 20.^[2]

Two details about this trial that matter for product selection. First, the trial used whole-mushroom dry powder — not a concentrated extract, and not fruiting-body-only. Second, the dose was 3,000 mg/day, three times what most capsule products deliver per serving.

This is the study that validated the whole-mushroom powder form. It's also the reason we formulated our product as a whole-mushroom powder rather than a concentrated extract.

Saitsu et al., 2019

Published in Biomedical Research. Thirty-one middle-aged adults without dementia took 3.2 g/day of Lion's Mane for 12 weeks. Significant cognitive improvements were observed on standardized tests.^[3] This trial extended the Mori findings to a slightly younger, cognitively-normal population, suggesting benefits aren't limited to people with existing impairment.

Docherty et al., 2023

Published in Nutrients. Forty-one healthy young adults (aged 18–45) received 1.8 g/day of Lion's Mane or placebo. Even a single dose improved Stroop-task reaction time at 60 minutes post-intake. At 28 days, there was a trend toward reduced subjective stress.^[4] This is important because it's the first trial to demonstrate an acute cognitive effect — not just a chronic one, in young, healthy adults.

Nagano et al., 2010

Published in Biomedical Research. Thirty women consumed Lion's Mane (in cookie form, approximately 2,000 mg/day) for 4 weeks. Significant reductions in self-reported anxiety, irritation, and depressive symptoms were observed relative to placebo.^[5]

Li et al., 2018

Published in the Journal of Medicinal Food. Adults with mild Alzheimer's disease received 1,000 mg/day of Lion's Mane for 49 weeks. Significant cognitive test-score improvements were observed compared to placebo.^[6] This is the longest human trial to date, and the results held over nearly a year of daily intake.

The six areas where Lion's Mane has evidence

Benefit	Evidence Level	Key Study	Dose Used
Cognitive function	Moderate (RCT)	Mori 2009 (n=30)	3 g/day × 16 wk
Mood support	Preliminary (RCT)	Nagano 2010 (n=30)	2 g/day × 4 wk
NGF stimulation	Strong (preclinical)	Lai 2013	In vitro / animal
Gut health	Preliminary	Sheng 2017	Animal model
Immune modulation	Preliminary	Kim 2012	Beta-glucan fraction

1. Cognitive function and focus

This is Lion's Mane's headline benefit and the one with the strongest evidence. The Mori, Saitsu, Docherty, and Li trials all point in the same direction: daily Lion's Mane intake at 1,000–3,200 mg supports measurable cognitive improvement, with effects building over weeks to months.

The mechanism, NGF stimulation leading to enhanced neuroplasticity and neuronal maintenance — is biologically plausible and supported by extensive preclinical work. For the practical experience of people using Lion's Mane for focus, see Lion's Mane for Brain Fog.

2. Memory

Memory improvement is closely tied to the cognitive-function findings. NGF supports the hippocampus, the brain region most directly involved in memory formation and retrieval. Animal studies have shown Lion's Mane can improve recognition memory and spatial memory.^[7] The human trials measured cognitive function broadly (which includes memory components), and the Li 2018 trial specifically noted improvements in processing speed and working memory.

3. Mood and emotional well-being

The Nagano 2010 trial showed significant reductions in anxiety and depressive symptoms after 4 weeks. The mechanism likely involves a combination of NGF-mediated brain health support and anti-inflammatory effects. Lion's Mane is not a replacement for mental health treatment, but the trial data suggests it can be a useful complement, particularly for stress-driven mood issues.

If stress and cortisol are the primary drivers of your mood symptoms, pairing Lion's Mane with Ashwagandha (KSM-66®) addresses both sides: Lion's Mane supports the neural infrastructure, Ashwagandha modulates the HPA-axis stress response. See Ashwagandha and Cortisol.

4. Nerve regeneration

Beyond the brain, NGF is active throughout the peripheral nervous system. Animal studies have shown that Lion's Mane can promote peripheral nerve regeneration after injury — accelerating functional recovery.^[8] Human evidence for this application is limited, but the biological mechanism (NGF stimulates nerve repair) is well-established. This area is relevant for anyone dealing with peripheral neuropathy or nerve-injury recovery.

5. Gut health

This compound has a traditional-use history for digestive health in Chinese medicine. Modern research has shown that Lion's Mane polysaccharides have gastroprotective effects in animal models, reducing gastric ulceration and supporting the gastric mucosa.^[9] The gut-brain axis connection means that improvements in gut health may also contribute indirectly to cognitive and mood benefits.

6. Immune modulation

Like most medicinal mushrooms, Lion's Mane contains beta-glucans that modulate immune function. A study published in Food & Function confirmed that Lion's Mane polysaccharides enhance immune cell activity and exhibit antioxidant properties.^[10] This is a shared benefit with other functional mushrooms rather than a unique Lion's Mane advantage. For a broader mushroom-based immune approach, see our guide to the best mushroom supplements.

Our product: what it is and what it isn't

Our Lion's Mane Mushroom delivers 1,000 mg per 2-capsule serving. Here's the full specification, exactly as it appears on the label:

Form: Organic Lion's Mane (Hericium erinaceus) Fruiting Body & Mycelium Powder
Standardization: 40% polysaccharides (400 mg per serving)
Capsule: Organic pullulan (vegan, fermentation-derived)
Other ingredient: Organic pea starch
Serving size: 2 capsules daily
Supply: 60 capsules (30-day supply)

Why whole-mushroom (fruiting body + mycelium) instead of fruiting-body-only?

Because the two parts of the mushroom contain different bioactive compounds. Hericenones are concentrated in the fruiting body. Erinacines, the compounds most directly studied for NGF stimulation in animal models — are concentrated in the mycelium. A fruiting-body-only product delivers hericenones but misses erinacines. A whole-mushroom formula delivers both.

The landmark Mori 2009 trial, the most-cited human evidence for Lion's Mane cognitive support, used whole-mushroom powder, not fruiting-body-only extract. Our formulation matches the form used in that trial.

Why powder instead of 10:1 extract?

Concentrated extracts (like 10:1) amplify water-soluble compounds (mainly polysaccharides and beta-glucans) but often lose fat-soluble and alcohol-soluble compounds like some hericenones. Whole-mushroom powder preserves the full compound spectrum. The trade-off is that the per-milligram potency is lower than a 10:1 extract, which is why the clinical trials use 1,000–3,200 mg/day of powder — not 100–320 mg of extract.

What about the pea starch?

Organic pea starch is a flow agent used during encapsulation, it prevents the powder from clumping inside the capsule machine. It's listed on the Supplement Facts panel under "Other Ingredients." Some brands claim "zero excipients" or "no fillers", in our experience, that usually means they're using a different excipient (like rice flour or magnesium stearate) and not listing it, or they're not manufacturing at commercial scale. We'd rather disclose everything than make a purity claim that doesn't hold up.

The mycelium-on-grain question

You'll read in many supplement guides — including older versions of our own articles, that you should "avoid mycelium" and "only buy fruiting body." That framing is oversimplified. The real quality issue isn't mycelium itself. It's mycelium grown on a grain substrate and never separated from it.

When mycelium is grown on rice or oats and the final product is the entire dried mass, grain plus mycelium, ground together — the result is typically 40–60% grain starch with diluted bioactive compound content. That's the "mycelium on grain" problem. The grain isn't separated, and what you're paying for is largely starch.

Our product uses mycelium that has been processed separately from its growth substrate. The final powder is mushroom material (fruiting body + clean mycelium), not a mushroom-grain composite. That distinction matters. For a detailed breakdown of the three quality tiers, see Lion's Mane Fruiting Body vs. Mycelium on Grain.

How to take Lion's Mane

Dose: 1,000 mg/day (our standard 2-capsule serving) is a reasonable daily dose for general cognitive support. If you want to match the Mori 2009 trial protocol more closely, 2,000–3,000 mg/day is the range used in that study, which means 2–3 servings of our product daily. That's a personal call based on your goals and budget.

Timing: Morning with food. Lion's Mane isn't a stimulant, so timing doesn't affect sleep, but taking it in the morning aligns the subtle cognitive support with your most productive hours. Can be taken with or without food, though food improves absorption of fat-soluble compounds like some hericenones.

Duration: Plan for at least 8 weeks of consistent daily use before evaluating. The clinical trials that showed significant results ran 12–49 weeks. Week-one evaluations are premature. See How Long Does Lion's Mane Take to Work for a week-by-week timeline.

Dosage guidance for specific goals: See It Dosage for a goal-by-goal breakdown (focus, memory, mood, neuroprotection).

Pairing Lion's Mane with other supplements

Lion's Mane stacks well with several other products in our lineup:

Lion's Mane + Mushroom Coffee: Coffee provides the acute caffeine alertness; Lion's Mane capsules provide the clinical-level long-term NGF dose. The coffee itself contains 5% Lion's Mane powder — a lighter daily exposure, and the capsules add the clinical-range dose on top.
Lion's Mane + Ashwagandha Plus: Different mechanisms for different aspects of cognitive wellness. Lion's Mane supports neural structure (NGF). Ashwagandha modulates the HPA axis and cortisol (stress response). Together they address both the "hardware" and "software" of mental clarity.
Lion's Mane + Magnesium Glycinate (evening): Lion's Mane in the morning for daytime cognition. Magnesium at night for sleep quality, 275 mg elemental magnesium from 2,500 mg of glycinate, 30–60 minutes before bed. Better sleep improves next-day cognitive function, making the Lion's Mane work in a more favorable baseline.

Who should not take Lion's Mane

People with mushroom allergies. True allergic reactions to medicinal mushrooms are uncommon but possible, and cross-reactivity with culinary mushroom allergies exists.
People on immunosuppressive medications. Beta-glucans modulate immune function, which can interfere with the intended action of immunosuppressive therapy.
Pregnant or breastfeeding women. Safety data on concentrated Lion's Mane intake during pregnancy is limited.
People approaching surgery. Some in-vitro evidence suggests Lion's Mane may have mild antiplatelet activity. Discontinue 7–14 days before scheduled procedures out of an abundance of caution.

For full safety information, see Mushroom Coffee Side Effects (the safety section covers Lion's Mane specifically).

What's new in lion's mane research: 2025–2026

Research interest in lion’s mane for brain health continued into 2026. A newly registered clinical trial (NCT06870136) is testing standardized extract in humans, which matters because much of the existing data comes from animal or in-vitro models.

The NGF mechanism: how lion's mane mushroom benefits the brain at the cellular level

Nerve growth factor (NGF) is a neurotrophin — a protein that supports the survival, development, and function of neurons. Unlike neurotransmitters that transmit signals between neurons, NGF maintains the physical infrastructure that makes signal transmission possible. It promotes myelination (the insulating sheath that speeds neural communication), supports axonal growth (the physical extensions that connect neurons to each other), and regulates synaptic plasticity (the ability of neural connections to strengthen or weaken based on use).

Lion's mane contains two families of compounds that stimulate NGF production: hericenones (found in the fruiting body) and erinacines (found in the mycelium). In cell culture studies, these compounds increased NGF mRNA expression and protein secretion from astrocytes, the brain's support cells that normally produce NGF. The key question, whether orally consumed lion's mane compounds cross the blood-brain barrier and stimulate central NGF production in living humans, remains technically unconfirmed, though the Mori 2009 cognitive improvement data is consistent with this mechanism.

What makes lion's mane mushroom benefits distinct from other cognitive supplements: most nootropics work by modulating neurotransmitter levels (caffeine blocks adenosine, L-theanine promotes alpha waves, racetams modulate acetylcholine). Lion's mane operates at the structural level — supporting the neurons themselves rather than the chemical signals between them. This is why the effects take weeks to manifest and why they reverse when supplementation stops: you are supporting ongoing neural maintenance, not creating an acute chemical shift. See lion's mane dosage for the clinical trial protocols.

What does lion's mane do at the molecular level?

Lion's mane contains two classes of bioactive compounds that are not found in any other commonly consumed mushroom. Hericenones, found primarily in the fruiting body, cross the blood-brain barrier and stimulate the production of nerve growth factor (NGF) from astrocytes. Erinacines, found primarily in the mycelium, stimulate NGF production through a different signaling pathway. NGF is a neurotrophin essential for the survival, maintenance, and regeneration of peripheral and central nervous system neurons.

Why does NGF stimulation matter? In healthy adults, NGF supports ongoing neural maintenance: myelin repair, synaptic plasticity (the physical basis of learning and memory), and the pruning of dysfunctional neural connections. In aging adults, NGF production naturally declines, which contributes to the gradual cognitive changes associated with normal aging, slower processing speed, more frequent word-finding difficulties, and reduced working memory capacity. The Mori 2009 trial demonstrated that exogenous NGF stimulation via lion's mane supplementation produced measurable cognitive improvements in elderly adults with mild cognitive impairment, improvements that reversed when supplementation stopped.

The reversibility finding is important: it confirms that lion's mane produces functional enhancement (better performance while the compound is present) rather than structural repair (permanent neural changes). This means ongoing daily supplementation is required to maintain the benefit, similar to how eyeglasses improve vision only while worn. For dosing protocols, see lion's mane dosage. For the quality difference between fruiting body and mycelium products, see fruiting body vs mycelium.

Comparing lion's mane to pharmaceutical nootropics and ADHD medications

This comparison needs to be made carefully and honestly, because social media frequently positions lion's mane as a "natural Adderall" or "mushroom nootropic that replaces medication." This framing is irresponsible and pharmacologically wrong.

Amphetamine-based ADHD medications (Adderall, Vyvanse) and methylphenidate (Ritalin, Concerta) work by directly increasing dopamine and norepinephrine signaling in the prefrontal cortex. Their effects are immediate, potent, measurable within 30 minutes, and produce obvious cognitive enhancement even in neurotypical individuals. They also carry significant risks: dependency potential, cardiovascular effects, appetite suppression, sleep disruption, and withdrawal symptoms.

Lion's mane works through NGF stimulation, a fundamentally different mechanism that operates over weeks, produces subtle improvements in neural maintenance rather than acute neurotransmitter flooding, and has no documented dependency, withdrawal, or cardiovascular risk. The trade-off is obvious: lion's mane is dramatically safer but dramatically less potent for acute cognitive enhancement.

The appropriate use cases do not overlap. ADHD medication treats a diagnosed neurodevelopmental condition under medical supervision. Lion's mane supports general cognitive maintenance in healthy adults seeking modest, long-term neural support. Positioning lion's mane as an alternative to prescribed ADHD medication is dangerous because it may discourage people with genuine ADHD from seeking the treatment they need. See lion's mane for attention and focus support for the specific evidence assessment.

The dose-quality interaction: why cheap lion's mane may not work

A recurring pattern in negative lion's mane reviews is "I took it for 8 weeks and felt nothing." Before concluding that lion's mane does not work, examine what you actually took. The Mori 2009 trial used 3,000 mg/day of whole fruiting body powder from a verified Hericium erinaceus source. A typical budget supplement contains 500 mg of mycelium-on-grain with 5 to 8% beta-glucans, meaning the active compound content may be 25 to 40 mg per capsule versus the approximately 15 to 30 mg of hericenones in each 1,000 mg serving of the Mori trial's whole fruiting body.

The practical math: at 500 mg of low-quality mycelium extract per day, you may be getting 5 to 10% of the active compounds used in the clinical trial. This is not a dose that should be expected to produce the cognitive improvements Mori documented. Before declaring lion's mane ineffective, verify three things: fruiting body source (not mycelium-on-grain), beta-glucan content ≥25%, and a daily dose of 500 to 1,000 mg of concentrated extract (or 2,000 to 3,000 mg of whole powder). If you were using a product that fails any of these three checks, your "lion's mane trial" was not actually a lion's mane trial — it was a grain starch trial at lion's mane prices. See fruiting body vs mycelium for the full quality breakdown.

Lion's mane versus other medicinal mushrooms: why the NGF mechanism is unique

Among the hundreds of edible and medicinal mushroom species, lion's mane occupies a unique pharmacological niche because of its NGF-stimulating compounds. Reishi (Ganoderma lucidum) provides immune modulation through beta-glucans and anti-inflammatory effects through ganoderic acids. Cordyceps provides exercise performance support through adenosine analogs and mitochondrial function enhancement. Chaga provides antioxidant activity through melanin and polyphenol content. Turkey tail provides immune support through PSK and PSP polysaccharides. None of these species contain the hericenones and erinacines that stimulate NGF production, which is what makes lion's mane the only mushroom with direct relevance to cognitive function and neural maintenance.

This uniqueness also means lion's mane cannot be substituted with other mushroom species. A product marketed as a "cognitive mushroom blend" that contains reishi, cordyceps, and chaga but no lion's mane provides zero NGF stimulation regardless of dose. Conversely, lion's mane does not provide the immune modulation, exercise performance, or antioxidant benefits of other species. For people wanting both cognitive and immune support, a multi-species approach (lion's mane for cognition, reishi or turkey tail for immunity) addresses both domains through distinct mechanisms. See adaptogenic mushrooms for the species-by-species evidence comparison.

Frequently asked questions

What does Lion's Mane do for your brain?

Lion's Mane contains hericenones and erinacines, compounds that stimulate Nerve Growth Factor (NGF) production. NGF supports the growth, maintenance, and repair of neurons. In human trials, daily Lion's Mane intake at 1,000–3,200 mg has been associated with improved cognitive function, memory, and reduced brain fog over 4–49 weeks of use.

How long does Lion's Mane take to work?

Most people report subtle improvements in focus and mental clarity at 2–4 weeks. More meaningful effects on memory, cognitive function, and brain fog typically emerge at 4–8 weeks. Clinical trials showing significant results ran 12–49 weeks. Lion's Mane is not a stimulant, it works through gradual neurotrophic pathways that build over time.

Is your Lion's Mane fruiting body only?

No. Our product is a whole-mushroom formula: organic fruiting body + mycelium powder, standardized to 40% polysaccharides (400 mg per serving). The fruiting body contributes hericenones; the mycelium contributes erinacines. Both compound classes are studied for NGF support. The Mori 2009 landmark cognitive trial used whole-mushroom powder — our formulation matches that form.

What's the difference between Lion's Mane powder and extract?

Powder is the dried, ground whole mushroom. Extract (e.g., 10:1) is a concentrated form that amplifies water-soluble compounds but often loses fat-soluble ones. Clinical trials have used both forms. We use powder to preserve the full compound spectrum, which is why our dosing is 1,000 mg per serving (matching the powder-form trials) rather than 100–200 mg (which would be an extract-equivalent dose).

What dose of Lion's Mane should I take?

Clinical trials have used 1,000–3,200 mg per day. Our product delivers 1,000 mg per 2-capsule serving. For general cognitive support, one serving daily is a reasonable starting point. For doses matching the Mori 2009 trial (3,000 mg/day), you'd need three servings daily. See Lion's Mane Dosage for a goal-specific guide.

Can I take Lion's Mane with coffee?

Yes. Lion's Mane is non-stimulating and pairs well with caffeine. Our Vitality Mushroom Coffee already contains 5% Lion's Mane powder blended into 90% Arabica, a lighter daily dose layered into the coffee ritual. Adding standalone Lion's Mane capsules on top provides the clinical-range dose.

Is Lion's Mane safe?

In clinical trials lasting up to 49 weeks, no serious adverse events have been reported in healthy adults. The most common side effect is mild gastrointestinal discomfort during the first few days. People with mushroom allergies, those on immunosuppressive medications, and pregnant women should consult a healthcare provider before use.

Why does your product contain mycelium if mycelium products are bad?

The problem isn't mycelium itself, it's mycelium grown on grain and never separated from it (the "mycelium on grain" issue), resulting in products that are 40–60% starch. Our mycelium is processed separately from its growth substrate. The final powder is mushroom material, not a grain composite. Erinacines — one of the two NGF-stimulating compound classes, are concentrated in the mycelium, so excluding mycelium entirely would mean losing half the bioactive profile.

What does Lion's Mane do?

Lion's Mane is a functional mushroom taken to support focus, memory, and cognitive function. Its hericenones and erinacines stimulate Nerve Growth Factor, a protein that helps maintain healthy neurons. Reported effects build over weeks of daily use rather than appearing immediately. It is sold as a dietary supplement and is not intended to diagnose, treat, cure, or prevent any disease.
