The sunshine vitamin, aka vitamin D is a whole-body health superstar. Its terrific for supporting bone health, immune and heart health, cognitive performance and so much more. But many of us dont get enough D3 from sunshine and diet alone (and sunshine shouldnt be the source of vitamin D). Thats where a high potency vitamin D3 supplement comes in, providing you with enough D3 levels for whole-body wellness. We recommend about 125 mcg (5,000 IU) to 200 mcg (8,000 IU) of daily vitamin D3. This D3 vitamin supplement is ideal to help your body reach optimal vitamin D3 levels.. 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 IU8,000 IU of vitamin D3 a day. If your multivitamin already delivers 1,0003,000 IU of vitamin D, Vitamin D3 5,000 IU is perfect for achieving optimal vitamin D levels. 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. 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. Heart health & 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 in the cardiovascular system, and encourages healthy endothelial function. Vitamin D also helps inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range. Getting enough vitamin D. This vitamin D3 supplement delivers 5,000 IU of vitamin D3 as cholecalciferol per softgel. 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 5080 ng/ml year-round. The sunshine vitaminYour skin makes vitamin D when its exposed to sunlight, but that shouldnt be your only source!
