D drops 1000IU, 5 ml

Vitamin D is made in the skin when exposed to summer sunlight (UVB), and is present in only a few foods. Vitamin D is necessary for healthy bones and normal muscle function. Vitamin D can be measured with a blood test for 25-Hydroxyvitamin D. The Institute of Medicine recommends this level should be higher than 20 ng/ml. A vitamin D supplement may be required to raise 25-Hydroxyvitamin D to healthy levels. Research findings show a 25 (OH)D blood level above 20 ng/ml is related to better health. A vitamin D3 supplement may be especially helpful for anyone who avoids exposing skin to sunshine.
