vitamin a + vitamin d + docosahexaenoic acid

This is a combination dietary supplement containing vitamin A, vitamin D (often as D3), and docosahexaenoic acid (DHA), an omega-3 fatty acid. It is primarily used to treat or prevent deficiencies of these nutrients before, during, and after pregnancy. The combination supports maternal health and fetal development—vitamin A is essential for vision and immune function; vitamin D aids calcium absorption and bone health; DHA supports brain and eye development in the fetus. These supplements are often marketed as prenatal vitamins but may also be used in other populations at risk of deficiency. Mechanistically: - Vitamin A acts mainly through retinoid receptors to regulate gene expression. - Vitamin D acts via the vitamin D receptor to modulate calcium/phosphate metabolism. - DHA incorporates into cell membranes (especially neural tissue) affecting membrane fluidity/function and has anti-inflammatory effects[1][4][7].
