Your appetite is quieter. Your nutrient needs are not. Anchor provides the protein, creatine, magnesium, and gut support your body still requires, formulated specifically for people on GLP-1 medications.
The four pillars
Pillar 01
Your muscles do not know your appetite is quieter. 25g whey isolate per serve — fast-absorbing, easy on a reduced stomach.
Shop protein
Pillar 02
22 peer-reviewed trials confirm it: creatine monohydrate protects lean mass during caloric restriction. 5g daily, no loading phase needed.
Shop creatine
Pillar 03
Constipation and disrupted sleep are often the same deficit. Magnesium glycinate is the chelated form with the highest gut tolerability.
Shop magnesium
Pillar 04
Eating less means less fiber. Prebiotic fiber supports gut motility, reduces bloating, and keeps digestion consistent.

In the STEP 1 trial, participants lost an average of 9.7% of lean body mass alongside fat. That is not a side effect — it is the expected consequence of eating less.
Creatine monohydrate is the most studied intervention for preserving lean mass during caloric restriction. 5g daily, no loading required.
GLP-1 medications can disrupt sleep during dose escalation. Fatigue on injection days is common and documented. Both trace back to the same micronutrient gap.
Magnesium glycinate absorbs before reaching the large intestine — better systemic absorption, less laxative effect than other forms.
Three peer-reviewed trials. Open access.

lean mass lost on semaglutide
In the STEP 1 trial (Wilding et al., NEJM 2021), participants averaged 9.7% lean body mass reduction. 74% of participants were female, mean age 46.

pounds lost was lean mass
In SURMOUNT-1 (Jastreboff et al., NEJM 2022), roughly 25% of total weight lost on tirzepatide was lean mass, confirmed by DXA substudy analysis.

trials confirm creatine protects lean mass
A meta-analysis of 22 randomised controlled trials (Chilibeck et al., BJSM 2017) found creatine plus resistance training significantly preserved lean mass vs. training alone.
