The scientific community is finding more and more reasons why vitamin D should be on the top of everyone's dietary supplement list. Vitamin D is one of the most important nutrients for maintaining overall health and wellness. While the human body does produce vitamin D with adequate exposure to sunlight, many people just don't get outside as often as they used to. Vitamin D-3 from MegaFood provides 1,000 IU in a whole food, bioactive form that is free of fish oil. This whole food supplement provides greater bioavailability than traditional vitamin D supplements.
