The science
Two mechanisms. Documented.
The research behind Amplify and Preserve.
Understanding GLP-1
What the medication actually does.
GLP-1 (glucagon-like peptide-1) is a hormone produced naturally by L-cells in the small intestine after eating. It signals fullness to the brain, slows gastric emptying, stimulates insulin secretion, and suppresses glucagon release.
GLP-1 receptor agonist medications — semaglutide (Ozempic, Wegovy), tirzepatide (Zepbound, Mounjaro), liraglutide (Saxenda) — work by mimicking this hormone at a sustained level, creating a prolonged state of appetite suppression and metabolic regulation.
The clinical results are significant: average weight loss of 15–20% of body weight in major trials, improved glycaemic control, reduced cardiovascular risk markers. These are real, meaningful outcomes for millions of people.
The physiological cost is also real.
What GLP-1 therapy depletes
The documented side effects nobody is supplementing for.
Lean muscle mass
Up to 25–40% of weight lost on GLP-1 can be lean mass without intervention.
A 2023 analysis found that semaglutide patients lost significant lean body mass alongside fat. This is not a minor side effect — muscle loss affects metabolism, strength, and long-term weight maintenance. The intervention with the strongest evidence base for preventing this is creatine monohydrate at 5g/day.
Micronutrient intake
A 20% reduction in food intake means a 20% reduction in nutrients.
GLP-1 medications reduce appetite significantly. Most users report eating 20–30% less than before. This creates cumulative micronutrient gaps — particularly in B12, magnesium, potassium, and iron — that standard dietary advice does not adequately address. Electrolyte supplementation and targeted nutrient support become clinically relevant.
Facial volume
Rapid fat loss redistributes unevenly — including facial adipose tissue.
The phenomenon colloquially known as "Ozempic face" is a documented consequence of rapid weight reduction affecting subcutaneous facial fat. It is not a cosmetic vanity — it is a physiological reality. Adequate protein intake, collagen support, and targeted nutrition all contribute to maintaining facial structure during active weight loss.
Amplify — the research
How berberine works alongside GLP-1.
Berberine is an alkaloid compound derived from several plants including Berberis vulgaris. It has been studied extensively for its effects on glucose metabolism, lipid profiles, and — most relevantly for GLP-1 users — its ability to stimulate endogenous GLP-1 secretion.
The mechanism: berberine activates AMP-activated protein kinase (AMPK), an enzyme that acts as a cellular energy sensor. AMPK activation in intestinal L-cells increases the secretion of GLP-1. This means berberine encourages your own gut to produce more of the hormone your medication is mimicking.
A 2020 meta-analysis in Frontiers in Pharmacology reviewed 46 randomised controlled trials and found berberine significantly reduced fasting blood glucose, HbA1c, and triglycerides. Multiple studies specifically document increased GLP-1 secretion with berberine use.
The clinical implication for GLP-1 medication users: berberine does not replace your medication. It works alongside it — through a complementary mechanism that supports the same metabolic pathway.
Preserve — the research
Why creatine is the standard of care for muscle preservation.
Creatine monohydrate is the most extensively studied performance supplement in existence — over 500 peer-reviewed studies spanning 30 years of research. The International Society of Sports Nutrition (ISSN) position stand describes it as the most effective nutritional supplement for increasing high-intensity exercise capacity and lean body mass.
The mechanism: creatine is stored in muscle as phosphocreatine. During exercise and periods of caloric restriction, phosphocreatine donates phosphate groups to regenerate ATP — the primary energy currency of muscle contraction. Higher phosphocreatine stores mean more energy available for muscle maintenance and recovery.
At 5g per day — the dose in Preserve — creatine has been consistently shown to reduce muscle breakdown during caloric restriction, improve recovery from exercise, and preserve lean mass during weight loss interventions. Recent research also documents cognitive benefits: improved memory and processing speed, particularly relevant for the fatigue GLP-1 users often report.
Safety profile: creatine monohydrate is one of the safest supplements studied. Long-term studies show no adverse effects on kidney or liver function in healthy individuals at standard doses.
