Natural Factors Vitamin D3 1000 IU

Vitamin D is made naturally in the skin from exposure to the sun 's ultraviolet rays. Vitamin D is a nutrient that helps in the development and maintenance of bones and teeth and helps your body absorb calcium and phosphorus. It also helps your muscles, nerves and immune system work properly.

This form of Vitamin D3 is carefully blended with organic flaxseed oil delivered in an easy-to-swallow softgel. Vitamin D is called "the sunshine vitamin" because we can usually get it from the sun's ultraviolet rays. People who live far away from the equator may make enough vitamin D in their skin during long, gloomy winters. It is essential for bone development and is needed for calcium and vitamin C absorption and it supports the nervous system. Vitamin D plays a dual role as both a vitamin and a hormone. Natural factors uses Vitamin D3, which is the form found in fish oils and eggs, and is produced by sunlight on human skin. Vitamin D3 (cholecalciferol from animal source) is derived from sheep wool lanolin.


    • Aids in the development and maintenance of bones and teeth
    • Helps reduce the risk of development osteoporosis when combined with adequate calcium
    • Supports healthy immune system function
    • Supports mother and child's health during pregnancy and lactation
    • Plays a role in reducing the risk of some cancers

Directions: 1 softgel per day or as directed by a health professional.

They melt in your mouth but not sublingual. This brand is well known and continues to provide top notch suppls. As for Vitasave it is a great, compassionate and great company with great service customer wraps. Keep on being who you are.


Everyone should take Vitamin D everyday.

Awesome boost

Excellent supplement to help maintain level of Vitamin D in the body for good bone health. Also, not enough sunshine in the winter months.

David Little
Sunshine in a bottle

Around this time of year I like to substitute the lack of sunshine with some vitamin D3. Natural Factors makes a great product in tablet form that is very cost effective.

Gary Barclay
Natural Factors Bilberry Extract 40 mg

One the most important supplements, especially during the winter months, at a great price.

Love these for my boys!!

We have been using the Renew brand from babies. Love this brand for the kids and I have just tried the adults ones too! ❤️

thank you, great service!

Good stuff

P. E. A. Is helpful for chronic pain and AOR is a reliable company. VitaSave delivers quickly with good prices.

Good replacement for Bob’s Red Mill!

I was so sad when Bob’s Red Mill stopped making their protein powder (the vanilla one I liked sweetened with monk fruit). This is a really good replacement. I recommend grinding up some chia seeds and adding it to your scoop. It’s sweet so I use half of a scoop at a time. But it tastes delicious with no aftertaste. Enjoy! :)
