Athletic Greens AG1 (Comprehensive Greens Powder)
AG1 is a multi-ingredient greens powder containing 75 vitamins, minerals, probiotics, adaptogens, and plant extracts designed as an all-in-one nutritional supplement. While individual ingredients have research support, the complete formula lacks extensive clinical trials as a whole product. Dietary supplements are not FDA-approved to diagnose, treat, cure, or prevent any disease. Consult your doctor before starting any supplement.
Key Takeaways
- AG1 contains 75+ vitamins, minerals, probiotics, adaptogens, and plant extracts in one powder, potentially replacing multiple individual supplements
- While individual ingredients have research support, the complete AG1 formula lacks extensive clinical trials as a whole product
- Standard dosage is one scoop (12g) mixed with water daily, preferably on an empty stomach in the morning
- The powder is vegan, gluten-free, dairy-free, and keto-friendly, making it suitable for various dietary restrictions
- At approximately $100 per month, it's significantly more expensive than taking individual supplements separately
How to Take
Typical Dosage
One scoop (12g) daily mixed with 8-10 oz cold water. This is the manufacturer's recommended dose; clinical research on the complete AG1 formula is limited to support optimal dosing.
When to Take
Best taken on an empty stomach in the morning, 30 minutes before breakfast for optimal absorption of nutrients and probiotics
Why It Matters for Ages 50+
Adults over 50 often have decreased nutrient absorption due to reduced stomach acid production and may have dietary gaps despite eating vegetables. AG1 provides concentrated nutrients in easily absorbed forms, though individual supplements targeting specific deficiencies identified through blood work may be more cost-effective and evidence-based for this age group.
What to Look For
- Look for third-party testing certificates to verify purity and potency of ingredients
- Check expiration dates and storage requirements - greens powders can degrade quickly when exposed to heat, light, or moisture
- Verify the product is free from artificial sweeteners, colors, and preservatives if those are concerns
- Ensure the powder dissolves well without clumping and has a fresh, not rancid smell
- Look for NSF or USP certification marks indicating independent quality verification
Potential Interactions
Be aware of these potential interactions:
- Anticoagulants (warfarin, aspirin, Eliquis, Xarelto): Contains vitamin K and various herbs that may affect bleeding time - consult your doctor before use
- Blood pressure medications (ACE inhibitors, beta-blockers): Adaptogenic herbs and potassium content may enhance blood pressure lowering effects
- Thyroid medications (levothyroxine): High fiber content and minerals may reduce thyroid medication absorption - take at least 4 hours apart
- Diabetes medications (metformin, insulin): Chromium and other ingredients may affect blood sugar levels - monitor glucose closely
- Immunosuppressive medications: Probiotics and immune-supporting ingredients may counteract immunosuppressive therapy
- Iron supplements: High antioxidant content may reduce iron absorption when taken together
Who Should Avoid This Supplement
- Individuals with compromised immune systems or those taking immunosuppressive medications due to probiotic and immune-supporting ingredients
- People with bleeding disorders or scheduled for surgery within two weeks due to vitamin K and herb content affecting clotting
- Those with severe kidney disease who need to restrict potassium, phosphorus, or certain vitamins
- Individuals with multiple food allergies or sensitivities who may react to the complex blend of 75+ ingredients

Frequently Asked Questions
Take AG1 first thing in the morning on an empty stomach for optimal absorption. Wait at least 30 minutes before eating breakfast and take thyroid medications at least 4 hours apart from AG1.
AG1 may replace a basic multivitamin and some individual supplements, but you may still need specific nutrients in higher doses depending on your individual needs. Consult your healthcare provider to determine what supplements you can safely discontinue.
Some people experience mild digestive upset, bloating, or changes in bowel movements when first starting due to the probiotics and fiber content. These effects typically resolve within a few days as your body adjusts.
Store AG1 in a cool, dry place away from direct sunlight and heat. Keep the container tightly sealed and use within the expiration date for maximum potency and freshness.
AG1 is more expensive than most alternatives but contains more ingredients and has some clinical research backing individual components. Whether it's worth the cost depends on your budget and whether you value the convenience of an all-in-one formula.
A varied diet rich in fruits, vegetables, and whole foods provides many of the same nutrients and is generally preferred. However, AG1 may help fill nutrient gaps for those with limited diets or increased nutritional needs due to age or health conditions.
