Vitamin D for Bone & Immune Support

Make sure you’re getting enough vitamin D3

Vitamin D is a fat-soluble vitamin that isn't easily obtained through diet alone. Vitamin D helps promote 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.

Vitamins D and K with Sea-Iodine™

Many people don’t get enough vitamin D3. Some don’t get enough vitamin K or iodine, either. This product has 125 mcg vitamin D3, 1000 mcg of iodine, and 2100 mcg of vitamin K (as K1 and K2).

Vitamins D and K with Sea-Iodine™

If you don’t get any vitamin D3 from your daily multivitamin (or don’t take one), these are the vitamin D3 supplements to choose from: they each deliver at least 125 mcg (5,000 IU) in every dose.

If you already get vitamin D3 in your multivitamin or have sufficient vitamin D3 intake from either diet or sun exposure (blood tests can tell you for sure), these lower dose formulas are perfect.

Maybe you’re trying to get enough of the trace mineral iodine. Maybe you’re trying to support healthy immune response. Or maybe you just want to take fewer supplements per day. Give these a try.

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.
