Vitamin D3, 125 µg (5000 IU), 60 softgels

Health benefits at a glance: 

Your skin produces vitamin D when exposed to ultraviolet B (UVB). However, because of sunscreen and weather during the winter season, the body’s ability to synthesize vitamin D can be hindered. 

Even if you spend plenty of time outdoors, your body still may not be producing enough of this very important vitamin. So, for most of us, it's not possible to get enough vitamin D from either sunlight or food alone.

This essential vitamin plays a crucial role in supporting nearly every cell in your body. It’s critical for optimal health, from brain and heart health to strong bones and a strong immune system. 

Research shows that vitamin D deficiency is common, which is why supplementation is recommended more than ever. This high-potency vitamin D supplement with easy-to-swallow capsules can make all the difference!

Why it works:

Vitamin D’s impact on cognition

Vitamin D promotes cognitive function and health as we age. Healthy serum vitamin D levels have been linked to better performance on cognitive tests and overall ability. (1-4) 

Vitamin D for bones, teeth & immune system

Vitamin D, alongside vitamin K and key minerals, is crucial for the transport of calcium into the bone matrix. This helps maintain bone and dental health. Vitamin D also plays a critical role in maintaining healthy immune function. (5,6)

Support for heart health & blood pressure

Vitamin D plays a vital role in regulating calcium balance in the body, facilitating calcium absorption from the digestive tract into the bloodstream. It supports cardiovascular health by promoting a healthy inflammatory response and endothelial function. (7,8) 

Moreover, vitamin D helps inhibit excess renin levels, which is important for maintaining healthy blood pressure within the normal range. (9)

The science behind the product:

This formula provides 125 mcg (5,000 IU) D3 as cholecalciferol per soft gel, perfect for reaching ideal levels. 

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, 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 D3 is contained in the multi-nutrient Life Extension Mix and the multivitamin Two-Per-Day Tablets/Capsules.

How to use:
