Beetroot Powder (Nitrate)

Beetroot powder (nitrate-standardized) is a concentrated whole-food ingredient typically derived from dehydrated Beta vulgaris. Key nutritional components per 5g serving (approximate): Carbohydrates: 3.5–4g (primarily sucrose, glucose, fructose); Dietary fiber: 0.5–0.8g (pectin, cellulose); Protein: 0.4–0.6g (containing glutamine, arginine precursors); Fat: <0.1g. Primary bioactive compound is inorganic nitrate (NO3−), standardized concentrations typically range from 250–500mg nitrate per 5–10g serving depending on product grade; dietary nitrate is converted via the enterosalivary nitrate-nitrite-nitric oxide pathway, with bioavailability of nitric oxide precursors estimated at 95–100% absorption in the upper GI tract. Betalains (betacyanins such as betanin: ~300–500mg/100g powder; betaxanthins such as vulgaxanthin: ~100–200mg/100g powder) act as potent antioxidants with moderate bioavailability (~25–40%). Micronutrients per 5g serving: Potassium: ~150–200mg (4–5% DV); Folate (B9): ~40–60mcg (10–15% DV); Magnesium: ~10–15mg (2–4% DV); Iron: ~0.5–0.8mg (3–4% DV, non-heme, moderate bioavailability enhanced by co-ingested vitamin C); Phosphorus: ~20–30mg; Vitamin C: ~5–10mg (partially degraded during processing). Also contains betaine (trimethylglycine): ~100–150mg per 5g, supporting methylation pathways; and manganese at trace levels (~0.1mg). Bioavailability note: nitrate absorption is rapid (peak plasma nitrite within 2–3 hours post-ingestion); betalain absorption is variable and influenced by oxalic acid content and gut microbiome composition.
