This supplement is pure vegan and no stearates are added to it. Vitamin D3 plays a crucial role in supporting many of the body's systems. That includes bones, brain and heart as well as tissues, the prostate and the immune system. Healthy vitamin D levels are essential throughout all stages of your life. Our bodies were made to create all the vitamin D we need, simply by absorbing sunlight as the sun is our primary source of vitamin D. In modern life, sometimes the weather can keep us from getting out in the sun as often as we should. Plus, only a small number of foods provide vitamin D, that's why many people simply can’t achieve the vitamin D levels they need for their best health. Premier Research Labs D3 Serum is high-potency and nature-sourced vitamin D3 supplement that offers 5,000 IU per serving of natural-source Vitamin D3. No artificial flavors, colorings or magnesium stearate are added to this formula. D3 Serum by Premier Research Labs supports bone growth, mineralization, absorption of calcium, cardiovascular and immune system health.
