“Taking, say, 6000 units vitamin D as tablets over 3 months yielded blood levels of 24-30 ng/ml. Taking 6000 units in an oil-based form, and blood levels would commonly be 60-70 ng/ml.
In other words, tablets are very poorly absorbed. I also saw very erratic absorption with tablets, with tremendous variation in blood levels.
Oil-filled gelcaps are no more expensive than tablets (or perhaps a dollar more). Health food store employees and pharmacists don’t know this. I have had many patients come to the office claiming they changed to tablets because that’s all their health food store or pharmacy carried and the person behind the counter assured them it was the same. Blood level of vitamin D to confirm: right back down to the starting level or near it–little or no absorption.
But, in my experience, having checked vitamin D blood levels thousands of times, gelcaps never fail; tablets fail over 80% of the time.”
