@autisticalyx: The ingredient is erythritol, a sugar alcohol in most sugar-free/keto protein products and sweeteners like Truvia. A 2023 Nature Medicine study (Witkowski et al.) found it’s linked to platelet activation and elevated cardiovascular event risk in humans — the same clotting pathway involved in menstrual and ovulatory pain. A 2026 Frontiers in Endocrinology study found erythritol exposure caused oxidative stress in ovarian tissue (elevated MDA, depleted glutathione/SOD), suppressed AMH — your ovarian reserve marker — and disrupted follicle development, with effects passed to the next generation. Endometriosis affects ~1 in 10 women of reproductive age and is itself a chronic inflammatory condition. None of the above studies were required for erythritol’s GRAS approval — GRAS testing is built around generic 90-day rat toxicity trials, not sex-stratified or endocrine-specific endpoints, and companies can self-affirm safety without independent FDA review. Women’s share of protein supplement consumption has risen to 35% as the industry expands past its historically male/athlete customer base — a market valued around $30B in 2026.
