Sustain adequate vitamin D levels throughout the year with Vitamin D3 and support whole-body health. Supplementing with vitamin D goes a long way. This vitamin D3 supplement delivers 25 mcg (1,000 IU) of vitamin D3 as cholecalciferol per softgel.
Vitamin D3 can help sustain adequate vitamin D levels throughout the year, which can be difficult for the body to produce - especially during the winter.
A supplement of vitamin D3 can promote healthy bone density, improve cognitive health, encourage healthy cell differentiation, and support immune function for better health.
Vitamin D3 can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight. Because of weather conditions during the winter season and sunblock, the body’s ability to produce vitamin D levels within the normal range may be inhibited.
Here's why you should be making sure you get enough of this essential vitamin every day:
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 may also help inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.
This vitamin D3 supplement delivers 25 mcg (1,000 IU) of vitamin D3 as cholecalciferol per softgel.
Current levels of vitamin D are very low in humans. Life Extension recommends that healthy adults supplement each day with at least 2,000 IU of vitamin D.
Elderly adults may benefit from higher doses such as 5,000 IU daily up to 10,000 IU daily. For most people, a 1,000 IU potency is insufficient to attain optimal vitamin D blood levels.
It's suggested 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.
Please note, that vitamin D is contained in the multi-nutrient Life Extension Mix and the multivitamin Two-Per-Day Tablets.
Please take according to the dosage and use guidelines under supplement facts, or as recommended by a healthcare practitioner.
