The Research

BAOBAB: To our knowledge, there are no trials in humans showing any benefits of baobab powder on immunity, energy or digestion.

BARLEY GRASS: To our knowledge, there are no trials in humans showing any benefit of barley grass powder on immunity, energy or digestion.

CHLORELLA: A randomised, controlled trial in 44 healthy volunteers found that consuming 27ml Chlorella water extract every day for 3 months led to improvements in antioxidant levels, as well as oxidative and aging stress markers. However, it is unclear on how much the dose in this product compares to this.

MORINGA: A randomised, controlled trial involving 20 healthy volunteers showed that a cookie containing 5% moringa powder resulted in significantly lower blood glucose and appetite levels after a meal. The amount of moringa powder used was 8.4g which is much larger than that found in a serving of the Clean Greens powder.

PINEAPPLE: To our knowledge, there are no trials in humans showing in benefit of pineapple powder on immunity, energy or digestion. Pineapple contains the enzyme bromelain. Bromelain may have some inflammatory effects at a dose of 160mg per day. However, it is unclear on the dose of bromelain in Clean Greens compared to clinical trials.

WHEATGRASS: The Clean Greens powder boasts about the high fibre content of wheatgrass. However, the amount of total fibre per serving is 1.7 g, which is not high fibre. To our knowledge, there are no human trial showing any benefits of wheatgrass powder on immunity or digestion.

SPIRULINA: A systematic review of randomised controlled trials demonstrated the improved blood lipid levels with the consumption of spirulina. In total, 20 studies involving a total of 1,076 volunteers, found significant improvements in cardiovascular risk factors, such as reduced LDL cholesterol and increased HDL cholesterol. However, the benefits were seen with doses of 4-10g/day, which is much larger than the dosage in a single serving of the Clean Greens drink.
