Two Twins. Same Genes. Completely Different Bodies.
Researchers studied 3,600 twin pairs — one lean, one overweight — and found the real dividing line wasn't diet or willpower. It was what was living in their gut. Biome® was built on that discovery.

- Diverse "lean bacteria" species
- Appetite naturally regulated
- Metabolism runs efficiently
- Lower fat storage
Twin B
- Microbiome dominated by few species
- Frequent hunger & cravings
- Metabolism runs sluggish
- Higher fat storage
Your Gut Bacteria May Be Running the Show
For years, weight gain was blamed almost entirely on diet and exercise. But a growing body of research from institutions including Stanford, Harvard, Yale, and Johns Hopkins points to a different, often-overlooked factor: the balance of bacteria living in your gut.
In lean individuals, researchers found a rich, diverse population of what's been informally called "lean bacteria" — species linked to appetite control, a faster metabolism, and lower fat storage. In people carrying more excess weight, that diversity was often replaced by a narrower set of species linked to the opposite effects.
Biome® was formulated around this research, combining nine clinically-studied "lean bacteria" strains with a caffeine-free green tea extract designed to help rebalance the gut microbiome.
Four Research-Backed Ingredients
Each strain in Biome® has been studied in its own published clinical trial. Here's what the research found.
Lactobacillus Gasseri
In a 12-week trial published in the British Journal of Nutrition, 210 overweight participants were split into two groups — one consuming milk containing L. Gasseri, the other a plain milk placebo.
Lactobacillus Rhamnosus
A 12-week study at Université Laval (Canada), also published in the British Journal of Nutrition, gave overweight women either L. Rhamnosus or a placebo.
Lactobacillus Fermentum
Researchers at the University of Manitoba tracked body fat changes over 43 days while both groups ate an identical diet, with only one group receiving L. Fermentum.
Greenselect Phytosome®
A 90-day trial gave one group of overweight participants this caffeine-free green tea extract alongside a calorie-controlled diet; the other group followed the diet alone.
Built to Actually Reach Your Gut
Live bacterial strains only work if they survive your stomach acid. Biome® uses delayed-release DRcaps® so the strains arrive intact where they're needed.
