I have to take a proton pump inhibitor (Prevacid) for frequent acid reflux. That class of drugs makes it more difficult to assimilate certain vitamins and minerals because they lower stomach acid. I was previously taking a Vitamin D3 from another company (not sold by Iherb). My vitamin D3 level was 32 which is low. Now I take 2 of these soft gels a day from Carlson and my Vitamin D level is 49 which is pretty good. Other people might do fine with just one soft gel a day. All prescription Vitamin D is Vitamin D2 which is the synthetic form and should be avoided. It does not work nearly as well as natural Vitamin D3 and can actually block the real Vitamin D3 from working properly.

I've seen great improvement in hair, nail and skin health since I began taking this supplement. The little vertical ridges that I have in my fingernails are going away. A very good value as well.
Best source of Vitamin 3

I had my first Vitamin D test a month ago and it was very low. After research I found out how important it is in every area of our body. Dr Mercola said the form to use is D3 and stresses that we must be tested before taking increased amounts -- lots of info at his web site. What I've also read is that we must take plenty of calcium with it. I'm taking 10,000 units D3 a day for a month then decreasing to 4,000 a day to build myself up. Then I will be tested again. I have had very notable increase in energy after taking it and just an increased level of well-being and health. My level was VERY low in the test, but it's not something to take increased amounts of if you don't need it. I feel very confident in the product because it had been recommended by Dr. Mercola before he started selling his own brand.
Stopped buying because...

From Ry: Here is my story about D3: I had been travelling for several consecutive months, and when finally home, my exhausted body felt a cold/flu trying to sprout. Several days of 10,000 units ended this threat dead in its tracks. I switched to Healthy Origins D3 because free of everything except necessary ingredients, sourced from lanolin, and comes in the preferable soft gel. I have stopped buying Carlson's D3 because of price, and because they cannot tell me if it has corn oil in it or not. Carlson can tell me that its D3 is salt-free, wheat-free, soy-free, yeast-free, sugar-free, milk-free, preservative-free, gluten-free. But they just don't know about corn oil ... ! Although the odds of corn oil being GMO are 85%, Carlson thinks this unimportant.
