Most of us grew up with a vague understanding that “getting our vitamins” was important, but the reasoning wasn’t always clear. A new study dives into the specific health benefits of one vitamin in particular—vitamin d—and its findings show that getting enough of it could be the key to living longer and aging healthfully. Meet the experts: joseph mercola, d. O. , board-certified family physician and author of your guide to cellular health; and amy davis, r. D. , l. D. N. , live conscious nutrition consultant. The trial followed more than 1,000 healthy american women over 55 years old and men over 50 for a period of four years and found that, compared to placebo, taking 2,000 international units (iu) of vitamin d3 daily helped slow down the shortening of telomeres.
While vitamin d supplements are widely available, the quality and effectiveness of vitamin d-containing supplements can differ significantly. Vitamin d3 is a more potent form compared to vitamin d2 and is more effective in correcting vitamin d deficiency and maintaining optimal levels. Low-dose vitamin d products often fail to maintain a healthy vitamin d status, and it’s recommended to opt for a supplement that contains at least 5000 iu of vitamin d3 per serving. It’s equally important to choose a vitamin d supplement with added vitamin k2. The best ratio of vitamin d3 to k2 is 1000:10, which means it contains 10 mcg of vitamin k2 per 1000 iu of vitamin d3.
