Calcium and Omega-3 are generally complementary — many people take them together. Omega-3 (1–3 g EPA+DHA/day) complements calcium supplementation for bone health and vascular function. Take with calcium-containing meals as the fat content enhances absorption of both nutrients.
Combined omega-3 and calcium supplementation shows improved bone mineral density in elderly populations compared to calcium alone. Omega-3s reduce inflammatory cytokines (IL-1β, TNF-α) that drive osteoclast activity, while calcium provides the substrate for mineralization. Meta-analyses confirm beneficial effects on bone biomarkers.
Omega-3 fatty acids (EPA/DHA) enhance calcium absorption by increasing intestinal membrane fluidity, facilitating calcium transport through enterocyte membranes. EPA and DHA also reduce urinary calcium excretion by modulating renal prostaglandin E2 levels. Additionally, omega-3s suppress NF-κB mediated osteoclastogenesis and promote osteoblast differentiation, complementing calcium's bone mineralization effects.
What to do: Omega-3 (1–3 g EPA+DHA/day) complements calcium supplementation for bone health and vascular function. Take with calcium-containing meals as the fat content enhances absorption of both nutrients.
