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 125 mcg–200 mcg of vitamin D3 a day. If your multivitamin already delivers 25 mcg–75 mcg of vitamin D, Vitamin D3 125 mcg (5000 IU) is perfect for achieving optimal vitamin D levels. More Cognitive health
Vitamin D is important for maintaining cognitive health and function as you age. Healthy serum vitamin D levels have been shown to correspond with better scores on cognitive health tests and better maintenance of cognitive ability in aging individuals.1-4
Bone and immune health
Vitamin D (along with vitamin K and essential minerals) is essential for facilitating the transport of calcium into the bone matrix. This is an important step in maintaining strong, healthy bones and teeth. Vitamin D also plays a critical role in healthy immune function.5,6
Heart health & already-healthy blood pressure support
Vitamin D helps to regulate the body’s calcium balance while facilitating calcium absorption into the bloodstream, promotes a healthy inflammatory response, and encourages healthy endothelial function.7 Vitamin D also helps inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.8
Getting enough vitamin D
This vitamin D3 supplement delivers 125 mcg of vitamin D3 as cholecalciferol per capsule. We suggest that you take a 25-hydroxy vitamin D blood test after 3 months to assess and adjust your dosage. Your optimal blood levels should be 50–80 ng/ml year-round. Less
