Immune, bone & whole body health
Your skin produces vitamin D when in direct sunlight or indoor tanning devices, but that’s not an ideal solution for obvious reasons. Choose a potent vitamin D3 supplement from Life Extension instead.

Basking in the sunshine is one of life’s greatest pleasures—and not only does it feel good, it’s good for us in moderation, because sunlight prompts our bodies to manufacture the essential nutrient, vitamin D. But it’s simply not possible for many of us to get enough vitamin D naturally. That’s why you need a potent vitamin D supplement.
Vitamin D is called the sunshine vitamin because your skin manufactures it when exposed to sunlight, but that shouldn’t be your only source. A vitamin D supplement goes a long way. We recommend about 125 mcg (5,000 IU) to 200 mcg (8,000 IU) of vitamin D3 a day. If your multivitamin already delivers 25-75 mcg (1,000–3,000 IU) of vitamin D, vitamin D3 125 mcg (5,000 IU) is perfect for achieving optimal 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 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.
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 & 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.7,8 Vitamin D also helps inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.9
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 50–80 ng/ml year-round.
Dosage and Use
Take one (1) softgel daily with food, or as recommended by a healthcare practitioner.
Individuals consuming more than 50 mcg (2000 IU)/day of vitamin D (from diet and supplements) should periodically obtain a serum 25-hydroxy vitamin D measurement. Do not exceed 10000 IU per day unless recommended by your doctor. Vitamin D supplementation is not recommended for individuals with high blood calcium levels.
