When it comes to the how vitamin D benefits us in more ways than is commonly known. The ‘sunshine’ vitamin, as it is sometimes called, is commonly known for its effect on strengthening the bones and joints in the human body by aiding the absorption of calcium. It also helps the body build up immunity. Our bodies can produce vitamin D without help, if we have sufficient amounts of sun (at least an hour a week). Alternatively, it is often added to certain foods such as milk, egg yolks, fatty fish, sardines, mackerel, tuna and salmon. These vitamin d rich foods are known to be a significant source of omega 3 fatty acids. Cod liver oil capsules are one of the most popular nutrient and Vitamin D dense supplements. I’ve found that adequate vitamin D levels are absolutely essential for maximized living. I hope it helps you as much as it did for me.
