Beet Root
Also known as: Beta vulgaris, beetroot, beet root juice, BRJ, dietary nitrate, betalain, betanin
Effective Dosage
500 ml juice (~5.1 mmol nitrate) or 100 mg betalain concentrate daily based on study doses
What the Science Says
Beet root is a vegetable naturally rich in dietary nitrates and pigments called betalains. When consumed, nitrates convert to nitric oxide in the body, which improves how efficiently muscles use oxygen during exercise — meaning you can do more work with less energy expenditure. Clinical trials show it can modestly improve cycling power output, extend time to exhaustion during high-intensity exercise, and may support healthier brain network organization in older adults when combined with regular exercise.
What It Doesn't Do
Won't dramatically transform athletic performance — improvements in studies are modest. No solid human evidence it lowers cholesterol or improves fertility (those studies were in animals only). The multi-ingredient supplement study can't isolate beet root's contribution. Not a weight loss supplement on its own. The food packaging and agricultural papers in the research pool have nothing to do with human health benefits.

Absorption & Bioavailability
Moderate — dietary nitrates from beet root juice are absorbed and converted to nitric oxide via a salivary bacteria pathway. Plasma nitrite levels rise measurably within days of supplementation. Betalain pigments are absorbed but bioavailability varies by individual gut microbiome and processing method.
Red Flags to Watch For
- Most performance benefits are modest (e.g., ~6 watts more power in cyclists) — marketing often exaggerates these effects
- Animal-only studies on cholesterol and fertility are frequently cited in marketing but have not been replicated in human clinical trials
- Beet root turns urine and stool red/pink (beeturia) — harmless but alarming if unexpected
- Multi-ingredient supplement products make it impossible to attribute benefits to beet root alone
- Several papers in the research pool (food packaging, agricultural science) are irrelevant to human supplementation — a sign the ingredient space is padded with weak evidence
