Consumer advice
If you struggle to eat vegetables and want a convenient greens powder, this is a decent option with good taste and third-party testing. However, don't expect dramatic digestive improvements or detox effects—those are marketing claims unsupported by the doses used. For the same nutritional benefit, you could buy a basic greens powder for $20-30, a separate probiotic for $15-20, and a multivitamin for $10-15, totaling $45-65 for 3 months versus $140 for KOS at full price. The subscription discount ($35.99/month) makes it more competitive but still premium-priced for what you get.
