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.

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

Source Naturals Vitamin D-3

Posted by 5357939797508878701 on May 02, 2016

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.

Good Product

Posted by lifebeyond50 on Feb 18, 2015

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.

Great D supplement

Posted by Reviewer1114141 on Dec 14, 2014

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.

Value for money !

Posted by Reviewer3211677 on Mar 31, 2014

I have been taking Vitamin D3 for almost two years. Got my supplies from Malaysia. Unfortunately to obtain my continuous supply was quite tedious since I live in Singapore. I went to iherb and found one from Source Naturals. I went through all the other Vitamin D3 but Source Naturals seemed quite similar to what I have been taking. Product reached me at my door within a week, which was great for a start. Hopefully, it is as good as it claims. thank you iherb for a super job in providing the community with convenience of shopping towards greater health care !
