Premium Vitamin D3 in Sunflower Oil for Maximum Absorption

2,500 IUs of D3 for Healthy Bones and Good Sleep

If there is one Vitamin to rule them all--look no further than Vitamin D. Receptors for this “sunshine vitamin” are found virtually everywhere in the body.1 Vitamin D plays a role in maintaining healthy immunity, bone health and positive attitudes.2-5 If you live in the US or Canada, and spend ample time indoors, it is possible you aren’t getting enough Vitamin D from its primary source: sun exposure. Research has suggested part of the US population is not getting optimal levels.6,7

During winter months far from the equator, UVB radiation from the sun is more limited. UVB radiation is required to stimulate adequate production of Vitamin D in the skin. Latitudes that include New York City and Boston may have limited exposure from November to March.8 During summer months, it is wise to use sunscreen and stay in the shade, but in doing so you are lowering the skin’s sun exposure to sun. Also, since vitamin D is not as plentiful in food, supplementing is an easy way to boost your levels.9

Nested Naturals Vitamin D3 is a potent, cruelty-free and easy way to supplement your levels of this critical vitamin. Each capsule gives you 2,500 IUs of premium quality, highly absorbable Vitamin D3 sourced from purified lanolin. We designed our gel-caps to be small and easy to swallow. As importantly, there’s no gnarly aftertaste that is common with other Vitamin D3 supplements.

The ingredients inside Vitamin D3

  • Highly Concentrated and Easy to Take

    One small, easy-to-swallow softgel of Nested Naturals Vitamin D3 gives you 2,500 IUs of premium D3.

  • No Fishy Aftertaste

    Check out the reviews and you’ll see that one of things people appreciate most about Nested Naturals Vitamin D3 is that there’s no aftertaste that’s common with other Vitamin D3 supplements.

  • Cruelty-free

    No animals are killed to produce this supplement. There are two main sources of Vitamin D3: fish oil and purified lanolin harvested from sheep’s wool. We opted to make Nested Naturals Vitamin D3 from purified lanolin, which we believe is the more animal-friendly choice. We’ve also made a conscious choice to make our soft gels from ingredients derived only from vegetables. There’s no gelatin which is produced from animal bones and marrow.
