Our immune system, muscles and bones need vitamin D to function normally. Yet deficiencies of vitamin D are common because many people don’t get enough exposure to sunlight or food containing vitamin D. The good news is that Pure D3 (formerly PurePharma D3) is formulated to compensate for this deficiency. It helps your body to absorb calcium and maintain normal bones. It is also known to help maintain the immune system. Quality! Sun or Supplement? The main source of vitamin D is exposure to the sun. Today’s busy working life doesn’t allow for much time spent outside so supplementing is an easy way to get the vitamin D you need. Healthy Fat Your body needs fat to absorb vitamin D. We combined Pure D3 with organic, virgin coconut oil to ensure that you get the maximum benefit. Dark Capsules Vitamin D is sensitive to light, which will degrade the vitamin. That’s why we use dark capsules and dark bottles to protect your D3 from exposure to light.
