Linus Pauling, a molecular biologist who is the only person to have won two unshared Nobel Prizes — one for Chemistry (1954) and one for Peace (1962) — once said, "I believe that you can, by taking some simple and inexpensive measures, extend your life and your years of well-being. My most important recommendation is that you take vitamins every day in optimum amounts, to supplement the vitamins you receive in your food." 

Research is solid in its support for this approach to health.

The latest? A study called COSMOS-Web reveals that overall, people who take a multivitamin daily have a brain age that is more than three years younger than those who take a placebo.

And if the people taking the supplement have cardiovascular disease, as around 75% of Americans from age 60 to 79 do, it's even more beneficial. That’s because it reduces plaque accumulation.

For even better results, I believe in taking a multivitamin-multimineral supplement along with some omega-3 DHA. That fills deficiencies in your diet, and offers the most complete protection for your brain, immune system, organ systems, and skin.

Your nutrition should be based on a mainly plant diet that delivers complex phytonutrients. Then, look for supplements that supply levels of nutrients that are near or close to their Recommended Daily Allowance. Don’t take mega doses.

And ask your doctor if you have any contraindications.
