Make sure you’re getting enough vitamin D
Vitamin D is a fat-soluble vitamin that isn't easily obtained through diet alone. Vitamin D helps preserve youthful cognitive function, supports bone and immune system health, helps maintain already-healthy blood pressure, encourages a healthy inflammatory response and promotes endothelial function. We recommend between about 5,000 IU to 8,000 IU of vitamin D3 a day.

Vitamin D3
Your skin manufactures vitamin D 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.

Vitamin D plus other nutrients
With multi-nutrient formulas, you get all the health benefits that come with vitamin D supplementation, plus other beneficial ingredients, such as calcium, vitamin K and iodine. These formulas provide support for healthy bone density, arterial health and more.
See Vitamin D plus other nutrients ProductsVitamin D helps preserve youthful cognitive function, supports bone and immune system health, helps maintain already-healthy blood pressure and more. If your multivitamin already delivers 1,000–3,000 IU of vitamin D, a high-potency vitamin D3 supplement would be ideal.
We’ve combined vitamin D3 with other nutrients, such as Sea-Iodine™ to support thyroid health, vitamin K to promote bone and arterial health, and calcium citrate to support healthy bone density.
What is vitamin D?
Vitamin D is a fat-soluble nutrient that plays an important role in many aspects of our health. Your skin produces vitamin D with sun exposure, which is why this nutrient is nicknamed the "sunshine vitamin." But many of us don't produce enough on our own.
What does vitamin D do?
Vitamin D plays a role in nearly every cell in our bodies—so it's critical for optimal health. One of its better-known functions is to help maintain strong bones and teeth by promoting calcium absorption. Vitamin D does this is by maintaining healthy levels of the parathyroid hormone, which plays an important role in maintaining calcium in the bloodstream.
Vitamin D also supports immune health, brain health, and maintains already-healthy blood pressure.
How much vitamin D should I take?
While it can be found in some foods, such as fatty fish (salmon, sardines, herring), it's not easy to get the vitamin D you need through diet alone. Vitamin D supplements come in various dosages. You can take vitamin D as capsules, tablets or even liquid drops.
So how much vitamin D is right for you? Life Extension recommends taking 125 mcg (5000 IU) of vitamin D3 a day, but you can get a clearer understanding of your needs by testing your blood levels.
As always, it's important to ask your doctor for advice on what approach works best for you.
