Reds Powder

Drink mixes of beet, berry and pomegranate powders sold for antioxidant support and circulation. The individual ingredients have real trial evidence, but the powders rarely disclose enough to know if they deliver a comparable dose.

Evidence last reviewed: August 2026

What the science says

Beetroot and blood pressure Moderate evidence
A systematic review and meta-analysis of randomised trials in hypertension found beetroot juice modestly lowered blood pressure, on the order of a few mmHg systolic. The effect depends on the nitrate content, which reds powders almost never state, and cooked or heavily processed beet powder can lose much of it.
Berry ingredients and blood pressure Limited evidence
A 2026 systematic review and meta-analysis of oral berry supplementation in adults with hypertension or elevated blood pressure found small effects with substantial heterogeneity across berry types, doses and preparations.
General antioxidant claims Limited evidence
No commercial reds powder has been tested in a randomised trial for any health outcome. ORAC values and total polyphenol figures printed on labels are laboratory measures with no established relationship to benefit in people.

Dosage & safety

Studied doseNo validated dose. Typical serving is one scoop (5-15 g) daily. For the blood pressure effect, the beetroot trials used doses supplying roughly 300-600 mg of dietary nitrate, which is more than most reds powders provide.

SafetyGenerally well tolerated. Beet can turn urine and stools pink, which is harmless but alarming if unexpected. Nitrate-rich products may add to the effect of blood pressure medication and of nitrates or PDE5 inhibitors such as sildenafil. Beet and some berries are high in oxalate, a concern for people with kidney stones. Many powders contain added sugars, stevia or caffeine, and some include herbal extracts not listed prominently.
