The purpose of this study was (1) to elucidate any reciprocal seasonal relationship that might exist between red cell folate (RCF) and serum vitamin D3 Levels; (2) to explore whether folate‐related gene variants that influence/alter DNA‐thymidylate and methyl group biosynthesis modify any associations detected in objective 1; and (3) to consider whether these processes might influence reproductive success consistent with the “folate‐vitamin D‐UV hypothesis of skin pigmentation” evolutionary model.
