↡ 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.

◊ Key health benefits:

(1) Immune system: With vitamins A, C, B6 and B12 as well as folate, zinc, copper and selenium, AG1 contributes to the normal function of the immune system. Vitamin C contributes to maintain the normal function of the immune system during and after intense physical exercise. 200 mg Vitamin C taken daily in addition to the recommended daily dose (80 mg) contributes to the normal function of the immune system during and after intensive physical activity.

(2) Energy levels: Vitamins C, B6, B12, riboflavin, niacin, pantothenic acid and magnesium contribute to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. Magnesium contributes to electrolyte balance. Biotin, zinc and chromium contribute to normal macronutrient metabolism.

(3) Digestion: Calcium contributes to the normal function of digestive enzymes. With vitamin A, biotin, riboflavin and niacin, AG1 contributes to the maintenance of normal mucous membranes (e.g. intestinal mucosa).

(4) Focus; Mental performance; Psychological function; Nervous system: With pantothenic acid, AG1 contributes to normal mental performance. Zinc contributes to normal cognitive function. With vitamins C, B6, B12, B1, B3 and B7 AG1 contributes to normal psychological function and to normal functioning of the nervous system. Calcium contributes to normal neurotransmission.

‡ Additional health benefits:

(5) Muscles: With calcium and magnesium, AG1 contributes to normal muscle function.

(6) Cell Protection: With vitamins E and C as well as riboflavin, zinc, copper and selenium, AG1 contributes to the protection of cells from oxidative stress. Phosphorus contributes to normal function of cell membranes. Folate, Vitamin B6 and B12 contribute to normal homocysteine metabolism.

(7) Skin, hair & nails: With vitamins A, as well as riboflavin, niacin, biotin and zinc, AG1 contributes to the maintenance of normal skin. Vitamin C contributes to normal collagen formation for the normal function of skin. Copper contributes to normal connective tissue. Vitamin B7, zinc and selenium contribute to the maintenance of normal hair. Zinc and selenium contribute to the maintenance of normal nails.

(8) Hormonal system: With vitamin B6, AG1 contributes to the regulation of hormonal activity. Zinc contributes to the maintenance of normal testosterone levels in the blood. Selenium contributes to the normal thyroid function. With chromium, AG1 contributes to the maintenance of normal blood glucose levels.
