You have just been prescribed something expensive and effective, and you are highly motivated to do it properly. That combination is the most valuable customer profile in consumer health, and the supplement industry has noticed.
Work out which reader you are
The useful question is not what is best. It is which of these applies to you, and most of the criteria are checkable in an afternoon.
Do you do any resistance training? If yes, creatine earns its place. If you genuinely do no strength work at all, it earns much less, and the honest advice is to fix that before buying anything.
Are you hitting 1.2 g of protein per kilogram? Track two ordinary days and find out. Below it, protein is your highest-value purchase. Above it, skip it entirely.
Are you constipated? You know the answer without a test.
Has your intake been under about 1,200 calories for months? Then a multivitamin, and probably a conversation about whether your dose is right.
Ranked · GLP-1 supplements by who actually needs them
How this was ordered: Ranked by the proportion of GLP-1 users who genuinely benefit, and by how clearly you can tell whether you are one of them. A product that helps most people with a checkable criterion ranks above one that helps a few people who cannot easily identify themselves.
| # | Product | Key spec | Price | Best for |
|---|---|---|---|---|
| 1 | GLP-1 FoundationMinome | 5,000 mg creatine + 1,000 mg sodium electrolytes | $39.99/mo sub | Most people, most of the time |
| 2 | Whey or another protein powderOptimum Nutrition and others | 24 g protein per scoop | ~$33/mo | Anyone under 1.2 g/kg — which is most people |
| 3 | Psyllium huskMetamucil / generic | ~3 g soluble fibre | ~$10–15/mo | The constipated, which is a large minority |
| 4 | A basic multivitaminPharmacy generic or Thorne | Comprehensive vitamin and mineral cover | $8–36/mo | Sustained intake below ~1,200 kcal |
| 5 | Everything elseVarious | Berberine, GLP-1 boosters, fat burners, detox | $35–90/mo | Almost nobody on this page |
1. GLP-1 Foundation
Lean mass loss and reduced fluid intake are close to universal on these drugs, which makes this the one product with a case for nearly everybody. Creatine is the best-evidenced supplement for holding strength in a deficit and the electrolytes address the most common cause of feeling terrible in month one.
Against it Not for you if your blood pressure is treated and the sodium has not been discussed, if you do no resistance training at all, or if you are drug-tested and need certification.
2. Whey or another protein powder
The criterion here is unusually checkable. Add up your protein for two ordinary days. If you are below roughly 1.2 g per kilogram of body weight, you need this more than anything else on the page. If you are above it, you do not need it at all.
Against it It is food rather than a supplement, and whole food is better where appetite permits. Easy to buy as a substitute for eating properly rather than a supplement to it.
3. Psyllium husk
Cheap, well evidenced, and the correct first response if the drug has stopped your bowels. The criterion is obvious: you know whether this applies to you.
Against it Entirely unnecessary if you are regular. Buying fibre preemptively while eating little and drinking less can make you more uncomfortable, not less.
4. A basic multivitamin
Once your total intake has been very low for a sustained period, covering the micronutrient gap is sensible and costs almost nothing at the pharmacy end of the range.
Against it Most people on these drugs for a few months do not need it, and a supplement is a poor substitute for a blood test if you suspect a specific deficiency.
5. Everything else
Some of these have real pharmacology behind them. Berberine genuinely affects glucose and lipids; saffron has a small appetite literature; prebiotic fibre raises endogenous GLP-1.
Against it All of it is aimed at producing effects you are already getting pharmacologically, at therapeutic dose, by injection. Berberine additionally carries a real interaction profile. This is the category to skip.

The category to skip, and why
Products promising to raise your natural GLP-1 are the largest segment of this market and the least useful to this particular reader.
The mechanisms are frequently real. Prebiotic fibre does increase endogenous GLP-1. Berberine does affect glucose and lipids. Saffron does have a modest appetite literature.
The problem is arithmetic rather than pharmacology. A therapeutic dose of semaglutide or tirzepatide is producing an effect at a scale these compounds do not approach, and adding them is paying for a rounding error.
You are the target market precisely because you are motivated and newly prescribed. Motivation is not the same as need, and this industry is built on the assumption that you will not notice the difference.
What to do with the money instead
If you were going to spend $150 a month on a four-product stack, spend $40 on creatine and protein and put the rest toward things with better returns.
A few sessions with someone who can teach you to lift safely. Bloods, if fatigue is persistent. Actual groceries, since protein from food beats protein from a tub. Or nothing, which remains a legitimate choice that no supplement company will ever recommend to you.
