How do you make vitamin D, which continues to be praised by health professionals and backed by innumerable scientific studies, even better? Combine it with the medium-chain triglyceride coconut oil. Our new Swanson Ultra Vitamin D-3 with Coconut Oil does just that. Not only does coconut oil provide quick energy able to be quickly broken down and used by the body, it aids in the rapid absorption of fat soluble vitamin D; the best of both worlds.
