Vitamin D3, 125 mcg (5000 IU), 60ct, Life Extension

Many of us don’t get enough vitamin D from sunshine and diet alone—but we need this nutrient for healthy bones and a strong immune system. This high-potency supplement fills in the gaps.

Your skin produces vitamin D when in direct sunlight, but you should not get your vitamin D from unprotected sun exposure or indoor tanning devices. Supplementing with vitamin D goes a long way towards inhibiting deficiency: we recommend about 5,000 IU–8,000 IU of vitamin D3 a day. If your multivitamin already delivers 1,000–3,000 IU of vitamin D, Vitamin D3 5,000 IU is perfect for achieving optimal vitamin D levels.
