Why no height/weight input? Unlike per-kg supplements (creatine, protein), Red Clover Isoflavones 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 directs one tablet daily (80 mg red clover isoflavones), taken at the same time each day with a meal.
This exact product was tested directly: a randomized, double-blind, placebo-controlled trial of 252 postmenopausal women compared Promensil (82 mg isoflavones/day, essentially this product’s own dose) against a second red clover supplement and placebo over 12 weeks. Neither red clover supplement significantly outperformed placebo in reducing hot flash frequency [1]. We’re citing this study because it’s the most direct test of this exact product at this exact dose, not because it supports a benefit — a later meta-analysis of pooled trials found a modest overall benefit, so the evidence across the broader literature is mixed.
As with the other calculators on our network, there’s no published bodyweight-adjusted dosing for red clover, so this tool plans by a fixed daily amount rather than your height or weight.
