A randomised comparison of increase in serum 25-hydroxyvitamin D concentration after 4 weeks of daily oral intake of 10 microg cholecalciferol from multivitamin tablets or fish oil capsules in healthy young adults. Holvik K, Madar AA, Meyer HE, Lofthus CM, Stene LC. Br J Nutr. 2007 Sep;98(3):620-5. Epub 2007 Apr 24. PMID: 17456248 We conclude that fish oil capsules and multivitamin tablets containing 10 microg cholecalciferol administered over a 4-week period produced a similar mean increase in s-25(OH)D concentration.

Use of cod liver oil during the first year of life is associated with lower risk of childhood-onset type 1 diabetes: a large, population-based, case-control study. Stene LC, Joner G; Norwegian Childhood Diabetes Study Group. Am J Clin Nutr. 2003 Dec;78(6):1128-34. PMID: 14668274 Conclusion: Cod liver oil may reduce the risk of type 1 diabetes, perhaps through the antiinflammatory effects of long-chain n-3 fatty acids.

"Lisa is one of early success stories: a heart scan score of 447 in her early 40's, modest reduction of CT heart scan score three years ago. However, Lisa had a difficult time locating oil-based vitamin D. There has, in fact, been a national run on vitamin D and I'm told that even manufacturers are scrambling to keep up with the booming demand. So, she bought tablets instead and was taking 3000 units per day. She came in for a routine check. Lisa's 25-OH-vitamin D3: 17 ng/ml, signifying severe deficiency, the same as if she were taking nothing at all. (Recall that we aim for 50 ng/ml.) In other words, vitamin D tablets do not work. It is shameful. I see numerous women taking calcium tablets with D--the vitamin D does not work. I've actually seen blood levels of zero on these preparations. "
