My doctor wants me to take 2000 IUs of D3 daily because a blood test showed I was low on D3. I get 900 IUs from other multi's I take, so I only need 1000 IUs and this tablet is perfect. I decided on this brand of D3 because I subscribe to an independent lab company that tests claims for potency, ingredients and heavy metals and Source Naturals tests well. I have taken as many as 2 of this little tablets, on an empty stomach, in the morning and no nausea. As a child, I choked on food that required the heimlich maneuver, so swallowing pills always brings anxiety for me. The tablets are small and coated so they swallow easily.

Excellent, food based vitamins, not synthetic.
Food based vitamins are important to me. No worries of allergy reactions like the synthetic ones. Source Naturals are the best.

Easy To Swallow Tablets
The tablets are small & very easy to swallow. Will update...when I have bloodwork again...& write more about this vitamin D3. Hoping it helps get my vitamin D3 up to normal range.

I like that I can chew it and that it is vegan with not too many ingredients. It arrived faster than expected.
