"Biohacker Bryan Johnson has lifted the lid on popular AG1 supplements, which he claims 'show no clinical benefit.' The 48-year-old biohacker, who claims to be more than a decade younger biologically, highlighted a clinical trial of Athletic Greens (AG1), an influencer-loved supplement powder that claims to support gut health, boost energy production, improve immune health and fill gaps in vital nutrients."
"Researchers then took stool samples from the participants and asked them questions about their digestive health. The study found that people who took AG1, had small improvements to their gut microbiome, the body's natural hub of healthy bacteria that influences metabolism, immune health and digestive function. There were also no negative effects, but the improvements were not statistically significant over people taking the placebo."
"AG1 powder costs $79 per month with a subscription and $99 for a one-time purchase. Each bag has 30 servings. Chicory inulin powder ranges from $13 to $25 for a 16-ounce container, while resistant starch powder is around $20 to $40 for the same amount, which can last for roughly a month. This adds up to $2.60 to $3.30 per serving of AG1 and between $0.40 and $1.33 for the alternatives."
A resurfaced 2024 clinical trial tested AG1 in 30 healthy adults, with half taking AG1 for four weeks and half receiving a placebo. Stool samples and digestive-health questionnaires were used to assess effects. The trial found small improvements to the gut microbiome among AG1 users and no negative effects, but those improvements did not reach statistical significance versus placebo, indicating longer-term research is needed. Cost comparisons show AG1 at roughly $2.60–$3.30 per serving, while chicory inulin and resistant starch alternatives cost about $0.40–$1.33 per serving.
