Evidence indicates that maintaining healthy levels of vitamin D can help mitigate cognitive decline. Plus, clinical trials confirm the importance of maintaining vitamin D levels for broad-spectrum health benefits, including bone health. If you are already getting 1,000–3,000 IU of vitamin D in your multivitamin, a 5,000 IU potency is perfect for achieving optimal vitamin D levels.
Benefits at a Glance
Vitamin D is a fat-soluble prohormone that effects the expression of more than 200 genes in your body.1 It is essential for optimal health, and yet there is a widespread vitamin D deficiency!
You can bring blood vitamin D to optimal levels2 through repeated sun exposure. But sunscreens and low light in winter make that difficult. And the American Academy of Dermatology has reaffirmed that vitamin D should not be obtained from unprotected exposure to ultraviolet (UV) radiation from the sun or indoor tanning devices.
We recommend that you supplement with 5,000 IU to 8,000 IU of vitamin D3 daily. And take a 25-hydroxyvitamin D blood test after 3 months to assess and adjust your dosage so your optimal blood levels will be between 50–80 ng/mL year-round.
Once vitamin D3 is produced in the skin or absorbed from food, it’s converted in the body to a metabolically active form known as calcitriol that does far more than just regulate your body’s calcium balance.3 Vitamin D affects cell differentiation, immunity, insulin secretion, blood pressure regulation, etc.4-33 So maintain optimal levels of blood vitamin D effectively and inexpensively with Life Extension® vitamin D supplements.Ratings based on results of the 2016 ConsumerLab.com Survey of Supplement Users.
|Dosage and Use|
Individuals consuming more than 2,000 IU/day of vitamin D (from diet and supplements) should periodically obtain a serum 25-hydroxy vitamin D measurement. Do not exceed 10,000 IU per day unless recommended by your doctor. Vitamin D supplementation is not recommended for individuals with high blood calcium levels.
