Offspring of parents who lived long lives had lower vitamin D levels.
Dutch researchers found that individuals in families who tend to live long lives have low levels of 25(OH) vitamin D. Offspring of parents who lived to their 90s had significantly lower levels than controls. This surprising finding does not prove cause, and many questions remain. Genetic studies suggest these offspring may have higher levels of an "aging suppressor" protein. Much more research is needed.
PositiveTip: Do not neglect appropriate sun exposure which is needed for the production of Vitamin D in the skin.
