Collagen for Women 40+ in menopause

Collagen is the primary structural protein in skin, bones, joints, and hair. Collagen production declines ~1% per year after age 30, and drops with menopause. Collagen peptide supplements (low molecular weight, easily absorbed) show moderate evidence for skin hydration and elasticity, and some evidence for bone density. Marine collagen (fish) is usually easier to verify as halal, but check the exact product label; bovine collagen needs halal certification.
