FAQs

Why is Vitamin D3 separate from AG1?

Vitamin D3 is one of the few nutrients that may vary depending on one’s lifestyle, age, diet, sun exposure, and vitamin D levels. Vitamin D is also best absorbed in liquid form and is best utilized by the body in combination with K2. We offer Vitamin D3+K2 liquid nutrient drops as part of our welcome offer for free.**

What products does AG1 replace?

One daily serving of AG1 eliminates the need for other supplements such as a multivitamin, multimineral, antioxidants, superfood blends, phytonutrients, greens blends, adaptogens, digestive enzymes, prebiotics, probiotics and synbiotics. You can trust AG1 to be effective with no compromises – ever – and the highest quality and greatest nutritional content.

How do I take AG1?

AG1 can be taken any time of the day, and ideally 10 minutes before a meal. AG1 works best in 8 to 10 ounces of cold water and taken on an empty stomach to optimize absorption. Drinking AG1 in cold water first thing in the morning before you start your day would be an ideal morning routine. We understand situations are not always ideal, and so we designed AG1 to fit into any scenario. AG1 can be taken during an intermittent fasting routine, after a meal, after and before exercise, in the afternoon to limit snacking, before a cheat meal, when traveling, during moments of high stress, and any combination of the above. AG1 was designed to be flexible to support your daily habit and set you up for a healthy success.

How does AG1 taste?

AG1’s fans praise its pleasant, healthy taste, and we’ve spent years perfecting the flavor. AG1’s flavor is naturally essenced with vanilla and pineapple, and picks up some of its taste from the fruits and vegetables in the blend including papaya, broccoli, cherry, carrot, and the subtle sweetness of stevia—all without artificial flavoring, sweeteners, and additives. No compromises.

Is AG1 a meal replacement with macronutrients like protein?

We firmly believe getting your macronutrients from whole foods is the most effective route to meeting your daily caloric needs. We designed AG1 to provide the micronutrients that are harder to come by and in bioavailable forms that your body can actually use. That's why it is only 50 calories and does not replace a healthy meal — it covers nutritional bases each day and provides additional phytonutrients that are hard to obtain in the diet.*

75 ingredients is a lot. Do I need all of these?

Our cutting-edge powder formulation is designed for superior absorption. Each vitamin, mineral, phytonutrient, and antioxidant was chosen not only for its bioavailability, but for how the ingredients amplify each other. This mimics how nutrients are found in nature, and how they work together in your body, enhancing the absorption in every scoop.*

Is AG1 suitable for my diet?

AG1 is Paleo, keto, and vegan friendly and has NO: wheat, dairy, gluten, corn, lactose, sucrose, dextrose, egg, yeast, peanuts, animal products, GMOs, herbicides, pesticides, harmful chemicals, artificial colors, preservatives, artificial sweeteners, or added sugar.AG1 is low allergen, has less than 1g of sugar per serving, and is suitable for most diets. If you have any concerns we recommend checking with your doctor. Our knowledgeable Customer Happiness team is available to answer any other questions you may have 1-888-390-4029, support@athleticgreens.com, or via chat.

⟡ Survey on the awareness of multi-nutrient powders with 211 consumers aged 18 to 49 in Germany, 09/24.

↡ Survey of 527 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. Vitamins C, B6, B12, riboflavin, niacin, pantothenic acid, and folate help reduce tiredness and fatigue. Pantothenic acid supports mental performance. Calcium supports normal digestive enzyme function, while biotin maintains normal mucous membranes, such as the gut lining.

◊ 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).

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.
