What Peptalyn is for

One daily supplement. Four areas of nutritional support.*

Peptalyn is made for adults who are taking a GLP-1 medication and want daily nutritional support. Here is what the label highlights, and what is in each serving.

Energy Support*

Includes B vitamins (thiamin, riboflavin, niacin, B6, folate, B12, biotin and pantothenic acid), plus chromium and magnesium.

GI / Nausea Support*

Includes ginger root extract, peppermint leaf extract, deglycyrrhizinated licorice extract, bromelain and Bacillus coagulans.

Hair, Skin & Nail Support*

Includes biotin (300 mcg) alongside the vitamins and minerals in each daily serving.

Bone Health Support*

Includes vitamin D3 (25 mcg, 1,000 IU), vitamin K2 as MK-7 (90 mcg) and magnesium (50 mg).

GLP-1 Nutritional Support*

The side effects nobody warned you about.

Semaglutide and tirzepatide do their job. They also empty your plate — and with it, the nutrition your body was running on. Peptalyn is the daily formula built for what happens next.

01

Fatigue and low energy

Less food means fewer of the B vitamins energy runs on.

Energy Support*
02

Nausea and GI upset

The most common reason people stop treatment.

GI / Nausea Support*
03

Hair thinning

Shedding that starts two to three months in.

Hair, Skin & Nail Support*
04

Bone density loss

Rapid weight loss pulls mineral out of hip and spine.

Bone Health Support*

Nineteen ingredients, four areas of nutritional support. Replacing what the medication takes out.

The formula

Built for the specific gaps a GLP-1 opens.

Most multivitamins assume you’re eating normally. On a GLP-1 you’re not. You’re eating less, digesting slower, and losing weight fast enough that your body starts drawing on reserves — mineral from bone, and whatever micronutrients aren’t coming in.

Peptalyn covers four areas of nutritional support at once: the energy metabolism that runs on B vitamins, the nausea and GI slowdown, the hair, skin and nails that show the shortfall, and the bone mineral at risk during rapid loss.

Four areas of nutritional support

What’s actually happening, and what we put in the capsule for it.*

What Peptalyn contributes, one area at a time.

Energy Support*

Full methylated B-complex · chromium · magnesium

Eating a third less food means taking in roughly a third less of everything that converts food into usable energy. B vitamins are not stored in quantity, they are cofactors, and when intake drops the shortfall shows up as flatness — not dramatic illness, just less of you to go around by mid-afternoon.

Two things compound. You are eating less, so less comes in. And gastric emptying is slower, so what does come in is absorbed differently. Even a carefully built plate struggles to hit daily values at the intakes a GLP-1 produces.

Thiamin, riboflavin, niacin, B6, folate, B12, biotin and pantothenic acid are all required cofactors in carbohydrate, fat and protein metabolism.

Institute of Medicine, Dietary Reference Intakes, 1998

Analyses of popular reduced-calorie diet plans found micronutrient sufficiency difficult to achieve, with deficiency risk rising as daily energy intake falls.

Calton, Journal of the International Society of Sports Nutrition, 2010

Peptalyn carries the complete B-complex in active, methylated forms, dosed for someone eating substantially less rather than someone eating normally — plus chromium for glucose metabolism and magnesium glycinate, the cofactor most of these reactions quietly depend on.

Form matters more when volume is low. Peptalyn uses L-methylfolate instead of folic acid, methylcobalamin instead of cyanocobalamin, P5P instead of pyridoxine hydrochloride, MK-7 instead of K1, and magnesium glycinate instead of oxide — chosen for absorption and for tolerability on an unsettled stomach.

In each serving

  • Thiamin 5 mg
  • Riboflavin 5 mg
  • Niacin 10 mg NE
  • Vitamin B6 (P5P) 2 mg
  • L-Methylfolate 400 mcg DFE
  • Methylcobalamin B12 250 mcg
  • Biotin 300 mcg
  • Pantothenic acid 10 mg
  • Chromium picolinate 200 mcg
  • Magnesium glycinate 50 mg

GI / Nausea Support*

Ginger · peppermint · DGL · spore probiotic · bromelain

Slowed gastric emptying is how these medications curb appetite. It is also why food sits heavy, why a normal portion suddenly feels like too much, and why nausea leads the list of reasons people abandon treatment before they reach a maintenance dose.

In the STEP 1 trial of semaglutide 2.4 mg, 44.2% of participants reported nausea, 31.5% diarrhea, 24.8% vomiting and 23.4% constipation (placebo: 17.4%, 15.9%, 6.6% and 9.5%).

Wilding et al., New England Journal of Medicine, 2021

Rather than masking the feeling, the GI blend works on the mechanics behind it: gingerols for nausea, menthol for smooth-muscle spasm, deglycyrrhizinated licorice for gastric lining comfort, a spore-based probiotic that survives stomach acid, and bromelain to help break down protein when digestion has slowed.

In each serving

  • Ginger root extract 100 mg (20% gingerols)
  • Peppermint leaf extract 50 mg
  • DGL licorice extract 100 mg
  • Bacillus coagulans 10 mg (1 billion CFU)
  • Bromelain powder 83.333 mg
  • Vitamin B6 (P5P) 2 mg

Hair, Skin & Nail Support*

Biotin · B12 · folate · leucine · bromelain

Shedding usually begins two to three months after a sharp drop in intake, which is why it feels like it came out of nowhere. The mechanism is telogen effluvium: follicles shift early out of their growth phase when the body starts triaging where protein and micronutrients go.

Rapid weight loss and inadequate intake of protein, iron, zinc, biotin and B12 are established contributors to telogen effluvium.

Guo & Katta, Dermatology Practical & Conceptual, 2017

Peptalyn supports the inputs hair depends on during the months your intake is lowest: biotin at 1,000% DV, the methylated B vitamins tied to cell turnover, L-leucine as an essential amino acid, and bromelain to help you actually absorb the protein you do eat.

In each serving

  • Biotin 300 mcg
  • Methylcobalamin B12 250 mcg
  • L-Methylfolate 400 mcg DFE
  • Riboflavin 5 mg
  • L-Leucine 250 mg
  • Bromelain powder 83.333 mg

Bone Health Support*

Vitamin D3 · K2 (MK-7) · magnesium

Weight comes off the whole body, not just fat. During rapid loss the skeleton gives up mineral, hip and spine first, and bone lost during a cut is not reliably regained afterward. It is the side effect with no symptoms, which is exactly why it goes unaddressed.

In a randomized trial, one year of GLP-1 treatment alone reduced bone mineral density at the hip and lumbar spine; combining treatment with exercise preserved it.

Jensen et al., JAMA Network Open, 2024

D3 to absorb calcium, K2 as MK-7 to direct it into bone rather than soft tissue, and magnesium as the cofactor both require. Resistance training and adequate protein do the heavy lifting here; Peptalyn covers the micronutrient side of it.

In each serving

  • Vitamin D3 25 mcg (1,000 IU)
  • Vitamin K2 as MK-7 90 mcg
  • Magnesium glycinate 50 mg

The research cited here examines the individual nutrients and botanicals in Peptalyn, or the physiological effects of GLP-1 receptor agonists and rapid weight loss. It does not evaluate Peptalyn itself.

Daily value not established for ginger, licorice, peppermint, Bacillus coagulans, bromelain, vitamin K2, HMB and L-leucine.

How to use it

Two capsules, with food, every day.

Suggested use, from the label: adults take 2 capsules daily with food. Capsules may be taken together or as 1 capsule twice daily.

01

Take both capsules with your largest meal

Food helps you absorb the fat-soluble vitamins, and the ginger and peppermint are most useful when there is something to settle.

02

Or split them — one morning, one evening

If two at once feels like a lot on a slow stomach, one capsule twice daily reaches the same daily serving.

03

Do not stop during a dose escalation

Escalation weeks are when GI symptoms spike and intake drops hardest. That is the week the formula is doing the most.

The research

What the research says about GLP-1 medications.

74.2% of people taking a once-weekly GLP-1 medication reported gastrointestinal side effects, including nausea (44.2%), versus 47.9% (GI) and 17.4% (nausea) on placebo.

This figure is about the medication in one clinical trial. It is not about Peptalyn, and it is not a claim about what Peptalyn does. Ingredient-level research for the nutrients in Peptalyn is collected on our science page.

Questions, answered

Good questions before you order.

How do I take Peptalyn?

Adults take 2 capsules daily with food. Capsules may be taken together or as 1 capsule twice daily. Do not exceed the recommended serving unless directed by a healthcare professional.

When should I take it?

With your largest meal. Food improves absorption of the fat-soluble vitamins (D3 and K2), and the ginger and peppermint are most useful when there is something in your stomach to settle.

Who is it for?

Peptalyn is a daily dietary supplement for adults who are taking a GLP-1 medication. It is not for children.

Can I take Peptalyn with semaglutide or tirzepatide?

Yes. It is a nutritional supplement, not a medication, and there is no timing conflict with your injection day. Two capsules daily with food. As with anything you add, tell your prescriber — particularly if you take an anticoagulant, since vitamin K2 is in the formula. Talk to your healthcare provider before use, especially if you are pregnant or nursing, have a medical condition, or take prescription or over-the-counter medications.

Will it interfere with my weight loss?

No. There are no calories, no stimulants, and nothing in the formula that increases appetite. Peptalyn addresses nutrition and side effects; the medication continues to do the appetite work.

Does it contain iron?

No, by design. Oral iron is a well-known cause of nausea and constipation, which are the two symptoms most likely to make someone stop their GLP-1. If you have documented iron deficiency, that should be treated separately with your clinician.

How long before I notice anything?

The GI blend — ginger, peppermint, DGL, and the probiotic — is the part people tend to notice first, often within the first week or two. The B vitamins, D3 and K2 work over weeks and months; the point of those is what you still have at the end of your course, not how you feel tomorrow.

When does it ship?

Peptalyn is available to pre-order now. Pre-orders ship starting December 1, and your cart line is marked “Pre-order” so our team can see it.

What’s in each capsule?

Every ingredient is listed with its amount above and in the Supplement Facts image in the product photo gallery; there are no proprietary blends. Capsules are vegetarian. Other ingredients: hypromellose, magnesium stearate and silicon dioxide.

Is it third-party tested?

Yes. Peptalyn is manufactured in a GMP-certified facility and tested by an independent lab. It is non-GMO and the capsules are vegetarian.

Is Peptalyn made by or affiliated with a GLP-1 drug maker?

No. Peptalyn is a dietary supplement from Free Life Labs. It is not affiliated with or endorsed by any GLP-1 medication manufacturer.

What’s your return policy?

Peptalyn is backed by our money-back guarantee. See the refund policy, or call 801-923-3878 or email support@freelifelabs.com.

Cover the gap while you’re in it.
