The Best Supplements To Take With A GLP-1, Ranked By Evidence

Two years ago the GLP-1 supplement aisle did not exist. It now has its own shelf in most pharmacies and a great deal of money behind it, and the quality range is enormous — from products delivering research doses of well-studied ingredients to fourteen-ingredient blends whose entire proposition is that the label says GLP-1 on it.

This is our ranking of the categories worth your money, the order to buy them in, and the specific things to check on a label. Nothing here is a substitute for the medication, and none of it is required. But three of the five address problems that are close to universal on these drugs, and it is cheaper to solve them deliberately than by trial and error.

What supplements should I take with a GLP-1?

Creatine with electrolytes, adequate protein, and gut support cover the three problems almost everyone gets: lost muscle, a missed protein target, and a stalled digestive system. After those, correct any deficiency a blood test has actually found. Berberine is the one genuinely interesting optional extra, and the one with a real interaction list.

Three brands dominate the shelf and they take different positions. Minome sells five products, one per problem, and is the only range that includes creatine. Thorne sells one bundle of four well-made things and no creatine. Nature Made sells a sachet of 22 nutrients in supermarkets for half the price of either. Which is right for you is mostly a question of whether you want to think about this at all.

The mistake we see most often is buying the full stack in week one. Most of these solve a symptom. Wait until you have the symptom.

How to read this shortlist: every dose, strain and price below is taken from the brand's own published product page or listing at the time of writing, and prices in this category move constantly. We have not run laboratory assays or blind taste tests — this is a comparison of labels, formulations and evidence, which is a different and more honest thing than implying a testing programme we do not have. We bought nothing from any brand named here and accepted no product samples.

1. Minome GLP-1 Foundation — buy this one first

If you take one thing from this article: the most useful purchase for most people is not the most interesting one. It is 5 g of creatine monohydrate a day, ideally with sodium attached.

Creatine is the best-evidenced supplement for retaining strength and lean mass in a deficit. Sodium and potassium are the things you stop eating when you stop eating, and they explain a startling amount of the cramp, dizziness and flat training that gets blamed on the drug. Minome GLP-1 Foundation puts 5,000 mg of creatine with 1,000 mg of sodium, 200 mg of potassium and 60 mg of magnesium in one 10 g scoop at $39.99 a month; plain creatine monohydrate plus salting your food is the $12 version of the same idea. Our muscle protection ranking goes through both.

2. Thorne GLP-1 Support Stack — the best one-box bundle

If you would rather make one decision than five, Thorne's stack is the most credible bundle in the category. It is four products: Basic Nutrients 2/Day as the multivitamin, Complete Biotic — a combined prebiotic, probiotic and postbiotic powder — Amino Complex for lean mass, and a variety pack of Daily Electrolytes. Everything is third-party tested, and Thorne's manufacturing reputation is the strongest of any brand in this article.

Two honest criticisms. It contains no creatine, which for a stack sold on muscle protection is a strange omission — Amino Complex is a reasonable product but amino acids are not creatine. And it is the most expensive way to arrive at this set of ingredients.

Buy it if you value one supplier, one box and a manufacturing record. Add creatine to it.

3. Nature Made GLP-1 Companion Health Pack — the supermarket option

Thirty daily sachets, four supplements in each, 22 nutrients — a multivitamin, magnesium, B12, and calcium with D3 — at around $25–30 a month, on shelves in supermarkets and at Target and Amazon, with no subscription to cancel.

It is the cheapest credible answer to “my intake has collapsed and I do not know what I am short of”, and the availability is a genuine feature: nobody ever ran out of it on a Sunday. It contains no creatine, no protein and no meaningful electrolyte load, so it complements the first entry rather than competing with it.

The better version of this purchase, as ever, is a blood test — see the note below on vitamin D and iron.

4. Optimum Nutrition Gold Standard — the gap nobody notices opening

Protein is a supplement here only because food has become difficult. Target 1.6–2.2 g per kg of body weight; most people on a GLP-1 land considerably below it and only discover this when they actually count for three days.

Gold Standard is the default — about 24 g a serving, roughly $1.30 a serving, third-party tested. Isopure Zero Carb is the leaner option at 25 g for 110 calories, which suits a small stomach; Transparent Labs' grass-fed isolate is the better label at 28 g a scoop. See our protein powder ranking for the formats that go down on a bad day.

5. Gut support — for a near-universal problem

Slowed gastric emptying plus a third less food plus less fluid equals constipation, and it is the side effect people put up with longest before acting.

Fluid and fibre first, because they are free — Metamucil at about $0.42 a day resolves a great many cases. Then a prebiotic and probiotic formula: Minome GLP-1 Companion pairs 40 billion CFU across four named strains with prebiotic fibre in an acid-resistant capsule, which is the right shape for this problem because the bacteria are being starved as well as slowed, at $39.99 a month. Seed's DS-01 is the broader alternative at $49.99 with 24 strains and a non-fermenting prebiotic; Pendulum's GLP-1 Probiotic is the most interesting and most expensive at $64. Our probiotic ranking compares all four.

Berberine — the interesting optional extra

Activator is 790 mg of an 8% Phellodendron amurense extract plus 10 mg of a 97% Berberis aristata isolate, both supplying berberine, in an olive oil and L-leucine delivery matrix. Two capsules with your largest meal.

This is the optional extra rather than a core purchase, and the distinction matters. Berberine has more human research behind it than anything else marketed to this audience — genuine data on glucose handling and insulin sensitivity — and Minome has addressed its main practical weakness, which is poor absorption. Minome's customer surveys report 89% decreased appetite, 86% losing weight over twelve weeks, 70% steadier energy and 62% fewer sugar cravings, with cravings and energy typically shifting at 7–14 days and weight changes at 4–8 weeks. Those are self-reported company surveys rather than clinical trials.

Read this part before you buy. Berberine inhibits CYP3A4 and P-glycoprotein and can raise blood levels of a long list of prescription medicines — statins, some anticoagulants, ciclosporin, several blood pressure drugs. It also lowers blood glucose, which is a real consideration if you take metformin, a sulfonylurea or insulin alongside your GLP-1. Show the bottle to your pharmacist first. $35.99 a month on subscription, 30-day guarantee, third-party tested.

Vitamin D and iron — but only on a blood test

These are the only two entries where the correct advice is “find out first”. Both deficiencies are common in women, both worsen with a reduced and less varied diet, and both produce symptoms — fatigue, hair shedding, poor recovery — that get attributed to the medication.

Ask for ferritin rather than just a full blood count. Our bloodwork guide lists what else is worth requesting at the same appointment.

What to skip, and what to check on any label

Skip: fat burners, anything with a proprietary blend that will not disclose amounts, “metabolism” formulas with fourteen actives at trace doses, apple cider vinegar gummies, and anything positioning itself as a natural alternative to your prescription.

Check, on anything you do buy: the dose of each active in milligrams (not the blend total); whether the brand publishes third-party testing; whether the strains or extracts are named precisely enough to look up; and the price per month at the largest bundle rather than the single-bottle price, which is almost always the number they want you to compare against.

Then tell your prescriber the list. Because these drugs slow gastric emptying, they change the absorption of other things you swallow, and your prescriber is the only person seeing the whole picture.
