Greens powder contains a variety of nutrients that may provide health benefits.

According to Athletic Greens, the product works in three ways:

  • Replenishing nutrients: The company claims the AG1 greens powder fills nutritional gaps and maintains cellular health. It also states the combination of antioxidants, superfoods, and stress adaptogens can maintain nutritional balance in the body.
  • Optimizing digestion: Reportedly, AG1 helps to optimize digestion because it contains prebiotics and probiotics. The powder is also highly absorbable, allowing the body to reap the benefits efficiently.
  • Pairing nutrients: The company states that it maximizes the efficiency of ingredients by pairing them appropriately. The company says this allows the nutrients to work cohesively rather than independently.

According to the company, individuals who consistently use AG1 may experience benefits within days, although for some, it may take weeks or even longer.

To use AG1, a person must mix 1 scoop with 10 ounces of cold water.

Athletic Greens claims the formula contains 75 vitamins, minerals, and whole-food sourced ingredients.

Vitamins and minerals

Vitamins and minerals are essential for the body to maintain good health.

AG1 contains 17 vitamins and minerals, including:

  • Vitamin A: This vitamin is essential for vision, epithelium, and immune health. There is also some evidence that vitamin A has cancer-preventive properties.
  • Vitamin C: The body uses vitamin C to help support skin, mucus membranes, blood vessels, and bone health.
  • Niacin: Niacin, or vitamin B3, can help decrease the risk of cardiovascular events, premature aging, and some age-related conditions, such as Alzheimer’s disease, Parkinson’s disease, and arthritis.
  • Folic acid: Although the main benefit of this vitamin is to help promote a healthy pregnancy, folate also plays an important role in red blood cell production. Folic acid can treat vitiligo and reduce inflammation.
  • Copper: This mineral helps produce energy, maintains connective tissue, protects against anemia, and helps the nervous system function properly. A deficiency in this mineral may lead to an increased risk of cardiovascular disease and Alzheimer’s disease. However, there is very little evidence of this link in humans.
  • Zinc: This mineral can help reduce the risk of age-related macular degeneration. There is some evidence that zinc can help prevent or reduce symptoms of the common cold and type 2 diabetes, but more research is necessary.
  • Selenium: This mineral may have some benefits, such as helping prevent cancer, cardiovascular disease, cognitive decline, and thyroid disorders. However, more research is necessary.
  • Potassium: This mineral can help protect bone health. While more research is necessary, it may also help protect against hypertension, stroke, and kidney stones.

Superfood complex

Athletic Greens states it uses a superfood complex, and the phytonutrients in this complex may help support the body’s microbiome.

Superfoods are food rich in nutrients. While there are real health benefits of many superfoods, it is important to note that there is no clear definition of what a superfood is.

Some superfoods in AG1 include:

Dairy-free probiotics

Probiotics can support digestive and immune system health and help the body synthesize vitamins.

Athletic Greens uses dairy-free probiotics, which may be beneficial for vegans or those who are lactose intolerant.

The company uses Bifidobacterium bifidum and Lactobacillus acidophilus in its formula.

Bifidobacterium bifidum may protect the intestinal lining from inflammation and reduce the risk of constipation. Lactobacillus acidophilus can balance gut bacteria, improve lactose intolerance, and protect against infections.

Plant extracts and antioxidants

Athletic Greens uses several plant extracts and antioxidants in its formula, including:

  • Ashwagandha root extract: This plant may help improve symptoms of insomnia and reduce symptoms of stress and anxiety.
  • Rosemary leaf extract: Rosemary has anti-inflammatory and neuroprotective properties.
  • Alkaline pea protein isolate: Pea protein has antioxidant, anti-inflammatory, and antihypertensive properties.

Enzyme and mushroom complex

AG1 has an enzyme and mushroom complex that contains shiitake and reishi mushroom powder.

Shiitake mushrooms may have properties that protect against cardiovascular diseases, whereas reishi mushroom may lower blood sugar and stimulate the immune system to fight off infections.

While there is currently no research on the benefits of AG1, there have been some studies on other greens powders.

A 2009 study found that people who took a greens powder supplement for 90 days experienced lower blood pressure. In a small 2011 study, researchers found that a greens powder supplement reduced oxidative stress over 4 weeks.

Greens powder contains a variety of vitamins, minerals, antioxidants, and probiotics. Many of the ingredients in AG1 are research-backed to provide short- and long-term benefits, including protecting against cardiovascular diseases and age-related conditions.

Athletic Greens claims that people may experience the following benefits when using the supplement:

  • After 30 days: improved digestion and energy levels, bowel regularity, and less cravings
  • After 60 days: comfortable digestion, reduced irritability, and improved concentration, focus, energy, and skin appearance
  • After 90 days: an overall feeling of wellness, plus improvements in recovery time, alertness, metabolism, and signs of aging

However, it is important to note that there has been no independent or published research proving these claims.

AG1 is not a substitute for eating a balanced diet. People should always try to get their recommended daily intake of nutrients from a diet rather than using supplements.

Using a dietary supplement that contains vitamins and minerals can lead to a person consuming too much. This can lead to side effects, some of which can seriously harm health.

For example, consuming too much vitamin C can increase the risk of developing kidney stones. Too much copper can cause nausea, cramps, and vomiting, and may even lead to liver damage.

Supplements can negatively interact with prescription and nonprescription medication. For example, vitamin E has a blood-thinning effect, and combining a supplement such as AG1 that contains this vitamin with medication such as warfarin, can have very dangerous results.

It is always important to discuss taking any new supplements with a healthcare professional before making a purchase.

People can purchase AG1 through Athletic Green’s website.

The company offers its supplements as a one-time purchase or as a subscription.

A one-time purchase costs $99. People will receive one pouch of AG1 containing 30 servings.

There are two subscription options: single and double. Both options ship monthly, have a 90-day money-back guarantee, and have the ability to pause or cancel the subscription at any time. A single subscription costs $79 and contains 30 servings, whereas a double subscription costs $150 and contains 60 servings.

If a person chooses to subscribe, their first subscription will come with a free starter kit of a premium jar and shaker.

Canceling a subscription

A person can cancel their subscription at any time. They can do this by logging into their account or by contacting the customer service team directly.

People can also make changes to their subscription, such as delivery date or frequency, at any time.

There are very limited customer reviews for AG1.

At time of publication, Athletic Greens has only one review on Trustpilot.

This review awards the company the full 5 stars and states they experienced health benefits and that the company has good customer service.

At time of publication, the Better Business Bureau gives the company a B- grade. Two reviews give the company an average of 1 out of 5 stars.

One reviewer states that the company created their password and said they could not change it, making them feel unsafe. The other says the company created an unauthorized subscription.

However, the formula contains various vitamins, minerals, antioxidants, and probiotics with real health benefits.

What are the side effects of Athletic Greens?

AG1 does not mention any possible side effects on the company website.

However, there are risks of the greens powder interacting negatively with prescription or nonprescription medication. People should always check with a healthcare professional before starting a new supplement.

Does Athletic Greens balance hormones?

According to AG1, after 90 continuous days of using the greens powder, a person may experience improvements to hormone health. This is due to the vitamins and minerals included in the formula.

However, there is no evidence to back up this claim.

Athletic Greens’ AG1 supplement is a greens powder that contains 75 ingredients that may benefit health. It includes vitamins, minerals, superfoods, probiotics, and mushrooms. However, it is more expensive than comparable products.

While greens powders can help fill nutritional gaps, it is important not to use them as a substitute for a nutritious diet. Ingredients in supplements can negatively interact with prescription and nonprescription medication.
