Product Overview


  • Dietary Supplement
  • Supports the Immune System and Strong Bones

Sunlight is the source of life on Earth, but we may not be aware of all the ways it benefits us. Our bodies manufacture vitamin D-3 when the skin is exposed to UV radiation from sunlight, but the ability to do so decreases as we age. Vitamin D-3 maintains healthy calcium and phosphorus levels in the body for strong bones; it increases muscle strength in older adults; and it also plays an active role in a healthy immune response. Vitamin D-3 (cholecalciferol) is the optimal form of vitamin D. It is the form of vitamin D that the body manufactures in sunlight, and the form most efficient for the body's needs.

Suggested Use

1 tablet 2 to 3 times daily, following a meal. Do not exceed suggested use.

Source Naturals Vitamin D-3

This is an excellent source of vitamin D, I find the tiny tablets are easy to swallow and are not damaged in transport to Australia. The soft gels I originally ordered all melded together, but upon your recomendation I switch to Source Naturals Vitamin D-3 tablets and find that they are excellent. I wouldn't hesitate to recommend them to anyone needing a little sunshine in a bottle.

Thanks for your feedback!

Good Product

I have been taking this supplement for the last one year but only now I will review it. It works great for me. I used to have what the doctor said a "mild arthritis" but this is now all in the past. I no longer have problems on my hands and feet.

Thanks for your feedback!

Great D supplement

Posted by iHerb Customer on Dec 14, 2014 | Verified Purchase

This is a great alternative to the oil vitamin D capsules which trigger a headache in me. They are easy to swallow and effectively helped to raise my vitamin D blood levels as advised by my doctor.
