↡ Survey of 2,618 AG1 customers after 12+ days of use, 2024. The survey was conducted on a previous version of AG1’s continually evolving formulation. The survey results can be transferred to the current version of the formula due to no or scientifically negligible changes in supporting nutrients.

◊ 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.

‡ Survey of 144 verified customers from 12 European countries who have been taking AG1 for an average of 9 days.
