"Salmon eggs benedict", the 'perfect' combo for 25OHD3 ( recipe ) "If, as has been suggested, 25(OH)D3 has five times greater bioactivity than vitamin D3, one cooked serve (100 g) of white fish, and one cooked serve of cage or free-range eggs (120 g) may provide 50% or 100%, respectively, of the current guidelines for the adequate intake of vitamin D (5 µg) for Australians aged 1–50 years," Australian researchers conclude in a recent paper that measured the concentration of vitamin D3 and 25-hydroxyvitamin D3 (25(OH)D3) in four species of white fish (barramundi, basa, hoki and king dory), and chicken eggs (cage and free-range), purchased from Adelaide, Brisbane, Melbourne, Perth and Sydney.

Nature knows best: Oils and other high PUFA foods come with a naturally high amount of vitamin E (see Fig 1 ). As a SuppVersity  reader you shouldn't be surprised to hear that there's a link between the amount of highly oxidizeable polyunsaturated fatty acids (omega-3 and omega-6) you consume and the amount of vitamin E you "need" to protect them from being oxidized by free radicals. The reason we usually speak about vitamin E in this context is that vitamin E (mostly alpha-tocopherol) is recognized as a if not the key essential lipophilic antioxidant in humans. It protects lipoproteins ( cholesterol ), PUFA, cellular and intra-cellular membranes from damage.

Bad News For Vitamin Fans - C + E Supplementation Blunts Increases in Total Lean Body and Leg Mass in Elderly Men After 12 Weeks of Std. Intense Strength Training

Chicken legs, old man? Must have been too much antioxidants ;-) If this is not your first SuppVersity article, you may have read about the potential negative effects of (high dose) anti-oxidant supplementation in previous SuppVersity articles about, or touching on the effects of hormesis , i.e. the beneficial effects of "good oxidative stress". Up to now I have yet often said that it is possible that this effect occurs mostly in people who can handle stress pretty well and thus have to hammer it to trigger a measurable adaptive response. The elderly subjects in the latest study from the University of Agder in Norway (Bjornson. 2015), however, don't exactly belong to the group of people I was thinking about, when I phrased this hypothesis.

Studies Confirm: Natural and Synthetic Vitamins Can Differ in Quantity & Quality of Effects! Vitamins A-E, B's & More

Pills or fruits, one are funky and useless, the other ancient and healthy!? In a 2000 paper in Medical Hypothesis , R.J. Thiel writes "[t]here appears to be a tendency to label those who profess that natural vitamins are better than synthetic ones as quacks" (Thiel. 2000). No wonder, after all, every good text book will inform future physicians and researchers that the difference between natural and synthetic alpha-tocopherol was a mere quantitative one. In other words, as long as you make sure that you administer 1.36x the amount of "natural" vitamin E in,   all-rac-α-tocopherol should do the exact same  as its natural cousin.
