      Food supplements are not a substitute for a balanced and varied diet and a healthy lifestyle. Do not exceed the indicated daily intake. Keep out of reach of children. Please inform and consult your doctor before consuming this product. Not suitable for children and adolescents under 18 years, pregnant or breastfeeding women. Refrain from taking other food supplements containing zinc. Persons taking anticoagulant medication should seek medical advice before consuming vitamin K-containing supplements.

      * Genuine reviews from customers who received a review link after purchase.

      **Offer valid for new subscribers only. Savings apply to first month only. First month includes AG1 (worth £79) plus a Welcome Kit (worth £28), Vitamin D3+K2 (worth £25), 5 Travel Packs (worth £15) – total value £147, reduced to £79 (save 40%+). Subscription continues at £79/month thereafter unless cancelled.

      ↡ Ongoing survey of 3,000+ AG1 customers after 12+ days of use, 2024.

      § In a third-party, observational study conducted on 35 healthy adults ages 25-48 assessing the self-perceived efficacy of AG1 over the course of 3 months. The study was conducted on a similar version of AG1's continually evolving formulation. The study results are transferable because of comparable ingredients and amounts.

      ○ Ongoing survey of customers from 12 European countries who have been taking AG1 for an average of 9 days.

      ⬥ Comparison (2025) with individual supplements in comparable amounts that are typically sold at retail: vitamin B complex, vitamin A, vitamin C, vitamin E, bacterial cultures, zinc, magnesium, calcium, selenium, chromium, manganese, molybdenum, coenzyme Q10, greens powders (from sea algae such as spirulina, barley leaf, wheatgrass, dandelion, spinach powder, etc.), mushroom supplements (reishi, shiitake). AG1 monthly price for single subscription (£79) calculated down to 30 daily portions. The comparison prices are the average prices per daily portion of three individual products (where available) available online in September 2025 (sample selection) for each compared category, each with identical ingredients. To ensure a fair basis for comparison, where the comparison products have different dosages, the prices were mathematically adjusted to correspond to the dosage contained in AG1. The amounts for the B complex may vary slightly. For the greens powders and the mushroom complex, the prices were compared per daily dose, quantities and ingredients vary and are not 100% identical.

      Research Studies
      a. In a triple-blind, randomised, placebo-controlled parallel-designed clinical trial evaluating nutrient biomarkers and microbiome shifts in 105 healthy adults ages 20-59 over the course of 12 weeks.
      b. In a double-blind, randomised, placebo-controlled 2-week cross-over clinical trial assessing microbiome shifts in 20 active adults ages 19-37.
      c. In a double-blind, randomised, placebo-controlled 2-week cross-over clinical trial assessing microbiome shifts of 24 healthy adults with occasional GI distress ages 26-59.
      d. In a double-blind, randomised, placebo-controlled cross-over clinical trial assessing bioavailability in 16 healthy adults ages 18-42 over the course of 8 hours.
      The studies were conducted on a similar version of AG1's continually evolving formulation. The transferability of the study results is ensured because of comparable ingredients and amounts.
