Feed Your Brain Vitamin D-3

While Ds in school show lack of brain function,Ds in pills boost your brain. Vitamin D-3 has become the "it" vitamin, thanks to a tsunami of studies showing that D's involved in more activities than a "Gossip Girl" socialite. From building bone to squelching inflammation, D-3 does something good for just about everything that keeps you strong, healthy and, according to new research, smart.
About the smart part: An international team reports that older adults with D deficiencies are at serious risk of losing their memory and thinking skills. The lower their D levels, the greater the decline. That's bad news if you're already a little low, as it likely will drop more as you age: When sun hits your skin at 20, it churns out four times as much D-3 as it does when you're 70. (Skin is your body's D-3 factory; sun fuels it.) The good news? It's easy to increase your vitamin D-3.
Since up to 75 percent of us are short on D-3, taking 1,000 mg a day (1,200 mg if you're over 60) is a no-brainer. Take it with a meal or a little fat (we take ours with our 900 mg of DHA omega-3 fatty acids).
We don't yet know if boosting D-3 with pills will mean less heart disease, cancer and diabetes — and a better memory. But we know for sure that walking outdoors, eating good-for-you foods, getting enough DHA, maintaining a healthy weight — and probably taking D-3 — will make your brain's RealAge younger. D-lightful.
