Centrum Nutrient Replenish Review 2026: What the Label Covers for GLP-1 Users

What We Checked, and When

We reviewed the Centrum Nutrient Replenish listings at Walmart, H-E-B, ShopRite, Stop & Shop and Martin's on October 17, 2026, along with Centrum's product claims and the published research on nutrition during GLP-1 therapy. We did not buy and lab-test the product. Every price, ingredient and claim below is tied to a page we read on that date.

Supplement reviews often read as if the writer held the bottle. We did not, and we would rather say so. This review is built from three sources: the retail listings that carry the product's label text, the brand's own wording about who the product is for, and peer-reviewed studies on what people taking semaglutide or tirzepatide actually eat and which deficiencies show up.

That approach has a limit worth naming at the start. Centrum does not publish the full Supplement Facts panel as text on its product page, and the retailers we checked either reproduce part of it or none of it. H-E-B's listing showed two lines: biotin at 30 mcg (100% of the Daily Value) and vitamin B6 at 6 mg (353%). The rest of the per-nutrient amounts were not available to us in a form we could quote. Where this review discusses doses, it says which numbers are confirmed and which are not.

Prices move. The figures here are the ones listed on October 17, 2026, and they will drift.

What the Bottle Says It Does

Centrum describes Nutrient Replenish as a complete multivitamin with 22 essential vitamins and minerals, 19 of them "high potency," meant to fill nutrient gaps for GLP-1 users and people on low-calorie diets. The label adds that Haleon does not sell or promote GLP-1 medications and tells buyers to talk with their healthcare provider before use.

Retail copy is consistent from store to store. from store to store. The product is "one easy to swallow mini size tablet" taken daily with food. It lists support for energy, metabolism, muscle function, bone health, immunity, and hair, skin and nails, each followed by an asterisk that leads to the standard FDA disclaimer. The bottle holds 180 tablets, which Centrum calls a six-month supply.

Two pieces of fine print matter more than the headline. First, the GLP-1 language carries its own footnote: Haleon does not sell, endorse or promote any particular GLP-1 medication, and buyers should consult a healthcare provider about their medication before taking the product. Second, the suggested use says the tablet is not formulated for children.

Centrum's long-running "#1 doctor recommended multivitamin" line also appears on the front of the box. "#1 doctor recommended multivitamin" line. That claim describes the Centrum brand as a whole, based on surveys of physicians. It does not mean doctors evaluated this particular formula, and it does not mean the formula was tested in people taking GLP-1 drugs. We found no published trial of Centrum Nutrient Replenish in any population.

Haleon itself was spun out of GSK's consumer health business in 2022. It is one of the largest over-the-counter health companies in the world, and Centrum is among its biggest brands. Scale brings real advantages, including wide distribution and mature manufacturing. It does not, by itself, tell you whether the amounts in this tablet fit your situation.

The Numbers We Could Confirm

From the retail listings we could confirm the nutrient count (22), the count of "high potency" ingredients (19), the presence of all eight B vitamins and vitamins A, C, D, E and K, the presence of iron, and two exact amounts: biotin 30 mcg and vitamin B6 6 mg. We could not confirm the amounts of vitamin D, vitamin B12, iron, magnesium, calcium or thiamine.

Below is everything the public listings supported, with the source for each line.

What we checked	What the listing showed	Where it appeared
Nutrient count	22 nutrients, 19 of them labeled "high potency" (at least 100% of the Daily Value)	H-E-B product copy
B vitamins	All eight named: thiamine, riboflavin, niacin, B6, folate, B12, biotin, pantothenic acid	All five retailers
Other vitamins	A, C, D, E and K listed as high potency	All five retailers
Iron	Present, shown by the federal iron warning; amount not shown	Stop & Shop, Martin's
Biotin	30 mcg (100% DV)	H-E-B nutrition panel
Vitamin B6	6 mg (353% DV)	H-E-B nutrition panel

Thiamine being on the list matters more than it might seem, for reasons covered further down; it has been at the center of the most serious case reports involving GLP-1 drugs.

What is missing from the public record is the part a GLP-1 user would most want to compare: the vitamin D amount in micrograms, the B12 amount, the iron amount, and the magnesium and calcium amounts. A note on magnesium and calcium: in most one-a-day tablets these two minerals appear at a small fraction of the Daily Value, because the full amounts are physically too bulky to fit in a single small tablet. A mini tablet has even less room. That is a general feature of the format, not something we measured in this product, and the only way to know for certain is to read your bottle.

What GLP-1 Nutrition Research Says to Watch

Published studies from 2026 point to protein as the most common shortfall during GLP-1 therapy, followed by several micronutrients, with vitamin D deficiency the most frequently diagnosed in claims data. Severe deficiency is uncommon but documented, mostly in people with prolonged vomiting or very low intake. The research supports routine nutrition attention, not alarm.

For a direct look at what people eat while taking these drugs comes from Korus et al. (2026). The Polish team recruited 387 adults from online support groups who were using a once-weekly GLP-1 or dual GIP/GLP-1 agonist and asked them to complete 48-hour food diaries. Average intake was 753 kcal a day, with 33.4 g of protein and 7.2 g of fiber. Fewer than 10% met protein recommendations. The authors concluded that this group had insufficient protein and critical micronutrients. The study is preliminary, the sample was self-selected online, and food diaries undercount, but the size of the gap is hard to dismiss.

Diagnosed deficiencies are a different measure from low intake. Kerr et al. (2026) analyzed insurance claims for 2,031 patients aged 10 to 17 who started a GLP-1 drug between 2017 and 2022, most of them on liraglutide. Within a year, 16.88% had a diagnosed nutritional deficiency or related complication. Vitamin D deficiency was the most common at 12.4%, followed by nutritional anemia at 1.55% and iron-deficiency anemia at 1.44%. Two cautions apply: these were adolescents, not adults, and the authors work for Abbott Nutrition, which sells nutrition products. The direction of the finding is still useful.

For adults, a 2026 narrative review on skin health summarized data showing vitamin D deficiency reaching 13.6% at 12 months of GLP-1 therapy and about 22.4% of patients having at least one documented deficiency within a year (Karlin et al., 2026). The authors listed vitamin D, iron, vitamin B12, folate, zinc, copper and protein as the nutrients most plausibly involved in the skin changes people notice after rapid weight loss.

Two broader 2026 reviews frame the issue the same way. Sorić et al. (2026) describe micronutrient status, protein adequacy and lean mass as emerging nutritional considerations in the GLP-1 era. A scientific statement from the Polish Society of Dietetics lists reduced energy intake, gastrointestinal side effects, loss of lean mass, and inadequate protein and micronutrient intake as the main nutritional challenges of these therapies (Kwaśny et al., 2026).

The rare but serious cases

Case reports describe what can happen when intake collapses for weeks. Cohan et al. (2026) reported a 65-year-old woman with type 2 diabetes and obesity who lost 120 pounds over months of semaglutide therapy with persistent nausea and vomiting. She developed profound weakness, trouble swallowing and cranial nerve deficits. Her thiamine, folate and B12 levels were low. Within five days of replacement she began to improve, and she made a partial recovery.

How rare is the severe end? When researchers went through FDA adverse event reports and published case reports, they counted 15 cases of Wernicke encephalopathy, the brain injury caused by severe thiamine deficiency, in people on GLP-1 drugs. Semaglutide and tirzepatide accounted for most of them, and 13 followed weight loss, vomiting, poor appetite or malnutrition (Lev et al., 2026). Against millions of prescriptions that is a very small number. It is still a reminder that thiamine stores are limited and that days of vomiting are a reason to call a clinician right away.

One widely shared case needs context. Crelier et al. (2026) described Korsakoff syndrome in a 50-year-old man after rapid weight loss on tirzepatide. He also had chronic alcohol use disorder, a major independent risk factor for thiamine deficiency. The authors framed the risk as applying to vulnerable individuals, particularly those who drink heavily.

Where a One-a-Day Mini Tablet Fits

A broad multivitamin can cover small, widespread shortfalls across many micronutrients at once, which is useful when total food intake drops. It cannot supply protein, and its fixed amounts may or may not match what your labs show. For vitamin D in particular, current guidance favors testing-led decisions in people with risk factors over blanket high doses.

Breadth is the strongest case for a product like this. When someone goes from 2,000 calories a day to under 1,000, intake of almost every micronutrient falls together. A tablet that supplies roughly a day's worth of most vitamins and minerals backfills that drop cheaply and without much thought. For a person with normal labs who is still eating real meals, that may be enough.

Protein, however, is the weakest point, and no tablet can fix it. A gram of protein is a gram of protein; it does not compress. Clinicians who manage GLP-1 patients put protein at the top of the list because lean mass lost during rapid weight loss is hard to rebuild. A review of the protein research found that higher-protein diets help with appetite and weight management, including retention of lean mass during energy restriction (Leidy et al., 2015). Our guide to preventing muscle loss on Ozempic covers food-first ways to close that gap.

Vitamin D is the nutrient people most often ask about, and the guidance is more nuanced than "take more." The Endocrine Society's 2024 guideline suggests empiric supplementation for specific groups, including children and teenagers, adults 75 and older, pregnant people and adults with high-risk prediabetes. For healthy adults aged 19 to 74 it suggests against supplementing above the recommended intake and against routine testing (Demay et al., 2024). GLP-1 users with obesity or diabetes often fall into higher-risk categories, which is why many prescribers check a 25(OH)D level. The practical point: the right vitamin D dose for you is the one your result supports, whatever bottle it comes from.

People sometimes worry that calcium and iron in the same tablet cancel each other out. Single-meal studies do show calcium reducing iron absorption, but longer studies in which calcium intake was raised for months found no change in blood measures of iron status (Lönnerdal, 2010). For a multivitamin taken with food, this interaction is a minor concern.

The Inactive Ingredients

Other ingredients in the tablet are modified corn starch and microcrystalline cellulose, plus less than 2% each of Blue 2 Lake, crospovidone, magnesium stearate, polyethylene glycol, polyvinyl alcohol, Red 40 Lake, silicon dioxide, soy lecithin, talc and titanium dioxide. It contains soy and is labeled non-GMO, gluten free, dairy free and nut free.

Most of that list is standard tablet engineering. Starch and cellulose give the tablet body. Crospovidone helps it break apart in the stomach. Magnesium stearate and silicon dioxide keep powders flowing through the machines. Polyvinyl alcohol, polyethylene glycol and talc form the coating that makes a tablet easier to swallow.

Three items get more attention from shoppers who read labels.

Titanium dioxide whitens the coating. The European Union stopped allowing it as a food additive (E171) in 2022 after the European Food Safety Authority concluded in 2021 that it could no longer be considered safe in food, mainly because genotoxicity could not be ruled out. It remains permitted in the United States, including in supplements. Whether that difference matters to you is a personal call; the amount in one coated mini tablet is small.

Blue 2 Lake and Red 40 Lake are synthetic colors. They give the tablet its look and do nothing nutritionally. Some competing GLP-1 products, including vitafusion's gummies, advertise "no synthetic FD&C dyes" as a selling point.

Soy lecithin is an emulsifier and the reason the label says "contains soy." People with a soy allergy should skip this product.

Testing and Transparency

We did not find a product-level USP Verified or NSF Certified seal on the Nutrient Replenish listings. The supplement database SuppCo reports that Centrum is backed by ISO 17025-accredited third-party testing and NSF-certified manufacturing, while noting that product-specific testing is not verified on its side. A batch certificate of analysis was not publicly posted for this product.

"Third-party tested" means different things on different labels, so it helps to separate three layers. A facility certification says the factory follows good manufacturing practice. A brand-level testing program says someone outside the company runs assays on products. A product seal such as USP Verified says an independent body checked this specific product against its label and audits it over time. Centrum appears to have the first two at the company level, according to SuppCo's summary. We did not find the third for Nutrient Replenish.

For shoppers, though, the bigger transparency gap is the label itself. Every supplement sold in the United States must carry a Supplement Facts panel on the package, so the information exists. It is simply not posted as searchable text on Centrum's product page or on the retail listings we checked, apart from the two lines H-E-B shows. That makes side-by-side comparison online harder than it needs to be. If you already own a bottle, the panel is on the back.

Cost Next to Other GLP-1-Labeled Options

At $0.11 a day, Centrum Nutrient Replenish was the least expensive GLP-1-labeled product we priced on October 17, 2026. Prices ranged up to about $7.50 a day for a three-part powder system. Cost per day says nothing about dose, so read this table alongside the label of whatever you are considering.

Product	Listed price	Days per package	Cost per day	Format	Contains protein
Centrum Nutrient Replenish	$19.96 (Walmart)	180	$0.11	1 mini tablet	No
vitafusion GLP-1 Support Multi	$8.29 (Walmart)	45	$0.18	2 gummies	No
Nature Made GLP-1 Companion Health Pack (discontinued)	$24.99 (Kroger)	30	$0.83	4 tablets per packet	No
GLP-1 SOS Daily Gut Relief	$23.99 to $49.99 (brand site)	30	$0.80 to $1.67	2 capsules	No
YourHealthier GLP-1 Companion (our product)	$47.99 (our site)	30	$1.60	2 capsules	No
SoWell GLP-1 Support System	$104.99 (brand site)	14	$7.50	3 powder stick packs	Yes, 25 g per pack

A few notes keep the table fair. GLP-1 SOS's lower price applies to its subscription; $49.99 is the one-time price. Nature Made's product is still on some store shelves but has been discontinued by the brand. SoWell's price covers three separate products, one of which is a protein powder, so the comparison with tablets and capsules is not like-for-like. We sell the YourHealthier product listed above, and we have labeled it so you can weigh our view accordingly.

What the table cannot show is dose. Two multivitamins at the same price can differ several-fold in vitamin D, B12 or magnesium. Centrum's price advantage is real. Whether it is a bargain for you depends on the amounts printed on the back of the bottle and on what your labs show.

How to Read Your Own Bottle

If you already have Centrum Nutrient Replenish or are holding it in a store, five lines on the Supplement Facts panel tell you most of what you need: vitamin D, vitamin B12, iron, magnesium and thiamine. Write those amounts down and compare them with your most recent lab results and your clinician's advice.

Flip the bottle over. Each line shows an amount and a percentage of the Daily Value. Five lines matter most.

Line on the panel	How to read it	What to compare it with
Vitamin D (mcg)	25 mcg equals 1,000 IU	Any amount your clinician set from a 25(OH)D result
Vitamin B12 (mcg)	The Daily Value is 2.4 mcg; absorption depends on stomach acid and intrinsic factor	Your B12 result, if it was low
Iron (mg)	Premenopausal women generally need more than men or older women	Your ferritin
Magnesium (mg and %DV)	A small percentage is normal for a one-a-day tablet	How much comes from your diet
Thiamine (B1)	Usually close to the daily requirement	Nothing on ordinary days; stretches of vomiting or near-zero intake mean a call to your prescriber

Bring the bottle or a photo of the panel to your next appointment. It turns a vague question ("is my multivitamin enough?") into a specific one your clinician can answer in a minute. Our GLP-1 nutrition checklist lists the labs most often discussed.

Who It Suits, and Who Should Look Further

Centrum Nutrient Replenish suits GLP-1 users who want inexpensive, broad micronutrient coverage, who still eat regular meals, and whose labs are normal. People with a known low lab value, people who avoid soy or synthetic dyes, and anyone who needs help with protein intake will need more than this tablet.

A good fit: You started a GLP-1 medication a few months ago. Your appetite is smaller but you still eat three modest meals. Your prescriber checked your labs and nothing was low. You want a simple daily backstop that costs less than a cup of coffee a month. This product does that job at the lowest price we found.

A partial fit: You already take specific supplements your clinician recommended, such as vitamin D or iron at a set dose. A broad multivitamin can sit underneath those, as long as you add up the totals so you do not double up past what was advised.

Look further if: Your bloodwork showed a deficiency. You are eating well under 1,000 calories most days. You have persistent fatigue on your GLP-1 medication or noticeable hair shedding, both of which call for a conversation and labs rather than a guess. You avoid soy or synthetic colors. Or your main struggle is protein, which no tablet addresses. A 2026 review drawing on bariatric surgery practice argued that GLP-1 treatment works best with structured dietetic care, including protein planning, symptom management and follow-up, rather than as a prescription alone (Balasubaramaniam et al., 2026).

What Changes If You Stop or Pause the Medication

When a GLP-1 medication is paused or stopped, appetite usually returns over weeks, and food again supplies most micronutrients. A broad multivitamin becomes less important at that point, while protein and overall diet quality stay important for keeping lean mass and managing weight regain.

Many people do not stay on these drugs indefinitely. Supply problems, cost, side effects and personal choice all lead to breaks. The nutrition picture changes when that happens. As appetite comes back, total food intake rises, and with it the intake of iron, magnesium, B vitamins and the rest. The case for a daily multivitamin as a backstop gets weaker, though it does not disappear for people whose diets were limited before they started.

Protein works the other way. Lean mass lost during the weight-loss phase does not come back on its own when the medication stops, and keeping protein intake steady through the transition helps protect what remains. If you are planning a break, our article on coming off Ozempic covers what people commonly notice and what to discuss with a prescriber.

For Centrum Nutrient Replenish specifically, a six-month bottle is a practical size for this pattern. It covers the period when intake is lowest, and an unfinished bottle simply becomes an ordinary multivitamin afterward.

Where It Fits in a GLP-1 Routine

Centrum Nutrient Replenish is a low-cost, broad multivitamin with a GLP-1 label. Its strengths are price, simplicity and coverage of all 22 listed nutrients in one small tablet. Its limits are the absence of protein, per-nutrient amounts that are hard to check online, and an ingredient list that includes titanium dioxide, synthetic dyes and soy. Used alongside labs and attention to protein, it is a sensible base layer.

Read the "GLP-1" on the box as a statement about who Centrum is marketing to. The formula is a conventional multivitamin, and there is nothing wrong with that; conventional multivitamins are inexpensive for a reason, and broad coverage has value when food intake drops. What the label cannot do is tell you whether its fixed amounts match your needs. Your labs can.

If you take one thing from this review, make it the order of priorities the research suggests: protein first, then the specific micronutrients your bloodwork flags, then a broad multivitamin to catch the rest. Centrum Nutrient Replenish fits well in that third slot. For a wider look at the categories, see our guide to the best supplements for GLP-1 users and our article on vitamins on Mounjaro or Zepbound.

Frequently Asked Questions

Does Centrum Nutrient Replenish contain iron?

Yes. The retail listings we checked carry the federal warning that applies only to iron-containing products. The iron amount was not shown in text on any listing we read on October 17, 2026, so check the Supplement Facts panel on the bottle.

How much vitamin D is in Centrum Nutrient Replenish?

Centrum lists vitamin D among its "high potency" vitamins, which means at least 100% of the Daily Value (20 mcg). The exact amount was not posted in text on Centrum's page or the retailer pages we checked. Read the panel on the bottle; 25 mcg on a label equals 1,000 IU.

Does it contain protein?

No. It is a vitamin and mineral tablet. Protein has to come from food or a separate protein product. GLP-1 nutrition research identifies protein as the most common shortfall during treatment (Korus et al., 2026).

Can I take it with semaglutide or tirzepatide?

One tablet daily with food, the label says, with food and to talk with your healthcare provider before use if you take medications. Haleon's own footnote asks GLP-1 users to consult their provider about their medication before starting the product. Standard multivitamins have no well-known interactions with GLP-1 drugs, but your prescriber knows your full medication list.

Is Centrum Nutrient Replenish third-party tested?

We did not find a product-specific USP Verified or NSF Certified seal. SuppCo, a supplement rating database, reports that Centrum is backed by ISO 17025-accredited third-party testing and NSF-certified manufacturing at the company level, and notes that it has not verified product-specific testing. No batch certificate of analysis was publicly posted for this product when we checked.
