Vitamin D3 is nicknamed the “sunshine” vitamin, because the human body only makes it after the skin is exposed to the sun. Most people don’t get enough sunlight to produce an efficient amount, which makes taking a vitamin D3 supplement all the more important. Essential for normal bone and dental health, this vitamin aids in the body’s absorption of calcium and has also been linked to immune health. At Country Life, our high-potency vitamin D3 1000 I.U. is ethically and sustainably sourced with 25 mg (1,000 I.U.) of non-fish-liver vitamin D3 to help maintain healthy bones and teeth.
