Usage

The only thing we advise against is mixing your AG1 with hot or very acidic liquids, as this could affect the integrity and efficacy of some of the ingredients.

Product Information

Since 2010, AG1 has continuously upgraded its formula, guided by the latest research on nutrition.

After years of development and four clinical trials, AG1 now features five new upgraded bacterial strains and an optimised nutrient profile to better meet your nutrient needs.

AG1 Upgrade

The easiest way to tell is by checking the serving size – the upgraded AG1 comes with a slightly increased daily portion (13g instead of 12g). You’ll also notice a few design changes:
  • A new hologram on the front of the pouch
  • A new product headline: "Daily Foundational Nutrition Support" (previously "Food Supplement with Sweetener")
  • Updated ingredient label on the back with five new bacterial strains and added magnesium.

Research Studies

Our peer-reviewed publications include both literature reviews and research on the AG1 original formula, which have been published in leading peer-reviewed journals, including Nutrients, Frontiers, Nutraceuticals, and the Journal of Functional Foods.

In addition, multiple clinical studies on the upgraded AG1 formula have been completed, and several abstracts have been presented at scientific conferences. We are also working on several manuscripts which will be submitted to peer reviewed journals and published upon acceptance.

Specialty Diets & Health Care

With very low amounts of carbs, proteins, and natural sugars, AG1 works with any time-restricted feeding (TRF) or intermittent fasting (IF) schedule.

If you have any questions about whether AG1 is right for you, please speak with your doctor.

Ingredients & Benefits

AG1 contains 1.2 grams of naturally occurring sugar per serving, with no added sugar and no artificial sweeteners. We use a small amount of stevia, a natural extract from the stevia rebaudiana leaf.

Manufacturing & Sourcing Standards

Lead occurs naturally in many whole foods. Anything that comes from the ground, including fruits, vegetables, and even drinking water, is likely to contain some heavy metals.

Each batch of AG1 is tested for heavy metals to ensure that the heavy metal content is below our own set limits, which are even well below the legal limits according to Regulation (EU) 2023/915, which defines a rigorous standard for safety, quality, and compliance.

AG1 tests significantly lower than these maximum statutory levels, despite the fact it contains more than 70 ingredients, many of which are whole foods that could naturally contain metals.

You can find our testing protocol and COA here.

↡ 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 (87€) 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.


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.
