Cycle-Aware Formulas Tune Iron, Magnesium, and Protein to Training
Brands now sell recovery drinks that adjust iron, magnesium, protein, and carbohydrate to training around the menstrual cycle, using studied doses such as 8 milligrams of iron and 200 milligrams of magnesium in a serving. Cycle-aware drinks price 30% to 70% above generic shakes and earn gross margins of 44% to 58% at scale. Women athletes, gym-goers, and runners aged 20 to 45 drive trial, and coaches and trainers add credibility. The trend needs evidence and modest claims, and it rewards brands that publish dose, cite studies, and guide training choices. Margins follow sourcing discipline.
