Why no height/weight input? Unlike per-kg supplements (creatine, protein), Black Seed Oil (Nigella sativa) has no published bodyweight-adjusted dosing in the research behind it. This calculator doesn't fabricate a per-kg formula that doesn't exist in the literature.

This product’s label serving is two 500 mg softgels daily (1,000 mg total). That matches the exact dose used in a 12-month, double-blind, randomized controlled trial of Nigella sativa (black seed) oil — 1,000 mg/day — though that trial studied Behçet’s disease, a specific inflammatory condition, and found the dose was not significantly more effective than placebo for that use [1]. We’re citing it here because it’s a real, dose-matched human trial, not because it proves a benefit — most of the positive black seed oil research (cholesterol, blood sugar) uses varying doses in the 500 mg–2 g/day range across shorter trials, and results are mixed across conditions.
As with the other calculators on our network, there’s no published bodyweight-adjusted dosing for black seed oil, so this tool plans by a fixed daily amount rather than your height or weight.
