In this 24-week study, oral supplementation with hydrolyzed low-molecular-weight porcine placental peptides significantly improved scalp elasticity, hair diameter, tensile strength, surface roughness, and luster compared to placebo, suggesting its potential as a nutritional intervention for age-related scalp and hair changes.
February 2026 in “Aesthetic Cosmetology and Medicine” In this case study, a 38-year-old woman with female androgenetic alopecia experienced improved hair density, reduced scalp oiliness, and enhanced hair structure after ten microneedle mesotherapy treatments combined with saw palmetto supplementation, with no adverse effects reported.
This study reports that their population showed significant prevalence of vitamin D deficiency, but the impact of supplementation on pregnancy rates remains unclear and requires more research.
March 2022 in “Annals of Bariatric Surgery” This study found that protein supplements combined with micronutrients reduced hair loss more effectively after sleeve gastrectomy in women, compared to routine multivitamins alone.
October 2008 in “Trace Elements and Electrolytes” In this study, perimenopausal women with initially high hair concentrations of calcium, magnesium, and silicon experienced a decrease in these elements after intermittent dietary supplementation with calcium, magnesium, silicon, and vitamin D.
The authors of this study concluded that higher calcium levels in hair may indicate early metabolic changes leading to osteopenia or osteoporosis in menopausal women, even before detectable by standard DEXA imaging.

January 2025 in “Journal of Research in Medical Sciences” This study reported that among obese women with PCOS, neither early time-restricted eating (eTRE) alone nor combined with probiotics showed significant improvements in blood pressure, inflammatory markers, oxidative stress, or antioxidant capacity compared to a standard reduced-calorie diet.
January 2025 in “Open Veterinary Journal” This case report described an 8-year-old Chihuahua with significant hair loss, where supplementation with horse placenta extract, taurine, and vitamin B complex led to marked hair regrowth and maintained coverage during a 76-week follow-up period, suggesting a potential non-invasive treatment option for alopecia in dogs.
August 2024 in “Journal of the Association of Physicians of India” This study examined 1,992 patients at a hospital in India for signs of B12 deficiency and found common symptoms included hair loss, poor memory, and weakness.
