How to Choose
Avoid Proprietary Blends
A "proprietary blend" of 10,000mg containing 40 ingredients means some ingredients are present at less than 250mg — likely subtherapeutic. Quality greens products either disclose individual doses or use a smaller number of ingredients at meaningful amounts. Transparent Labs is the gold standard for disclosure in this category.
Check for Heavy Metal Testing
Spirulina, chlorella, and other algae can accumulate heavy metals (lead, arsenic, mercury) from their growing environment. Third-party heavy metal testing is not optional for greens powders — it is essential. Look for products with published certificates of analysis or NSF/USP certification.
Digestive Enzymes and Probiotics Add Real Value
Many people experience bloating from concentrated greens. Products that include digestive enzymes (bromelain, amylase, lipase) and probiotics reduce this common side effect while improving nutrient absorption. These additions are not marketing fluff — they genuinely improve the user experience and nutritional value.
How We Evaluate
Every product is scored against these weighted criteria. Our ratings reflect clinical evidence and product quality, not commission rates.
Ingredient Transparency
30%We strongly penalize proprietary blends that hide individual ingredient doses. You deserve to know exactly how much spirulina, chlorella, and other ingredients you are getting.
Superfood Diversity & Dose
25%Quality greens should include core ingredients (spirulina, chlorella, wheatgrass, barley grass) at meaningful doses, not trace amounts of 50+ ingredients.
Digestive Support
15%Added digestive enzymes (bromelain, amylase) and probiotics improve absorption and reduce bloating. These additions add genuine value.
Testing & Safety
20%Third-party testing for heavy metals is critical for greens powders since algae and grasses can accumulate contaminants. NSF or independent lab verification preferred.
Taste & Usability
10%A greens powder you will not drink consistently is worthless. We factor in taste, mixability, and convenience.

Is AG1 worth the price?
At $2.63/serving, AG1 is significantly more expensive than alternatives. However, it replaces multiple supplements (greens, multivitamin, probiotics, digestive enzymes) and is NSF Certified for Sport. If you would otherwise buy these separately, AG1 may actually save money and simplify your routine. If you only want a basic greens supplement, more affordable options deliver the core benefits.
