Written by | published on

All nuts are good tocopherol (T) sources, but α- T is predominantly found in peanuts, almonds and sunflower seeds, while γ-T is the major vitamin E in walnuts, pecans and pistachios. Over the past week I've been questioning the potency of various supplement superstars with respect to their ability to improve your, my or any one else's glucose metabolism. We've dealt with protein, peptides, fats, vitamin D, calcium, a whole host of B-vitamins and even the underrated vitamin A (go back and review all of them ). Today I am going to take a look at a "fallen star", vitamin E, once thought of as a panacea and universal protector of your cells, it has, at the latest with publication of the disappointing, if not shocking results of the SELECT trial in 2013 and the mass-media reverberations about increased prostate cancer risk, become the centerpiece (literally) of every anti-vitamin supplement rant.

Biotin, Folic Acid & B12 & Glucose Management | Part IX of the "There is More To Glucose Control Than Low Carb" - Series: Are Extra "B"s Good for Non-Diabetics as Well?

There is evidence for beneficial effects of B7 and B12 in Alzheimer's. Yet although the this disease is often called "diabetes of the brain" the evidence that B7 and B12 would do anything but ameliorate the damage due to increased blood glucose levels and decreases insulin sensitivity is non-existent. I guess, you will remember that my analysis of the role of thiamin (B1), riboflavin (B2), pantothenic acid (B5) and pyridoxin (B6) revealed... well, what did it reveal? Not much, aside from the fact that the importance of these B-vitamins in glucose management is probably overrated. For niacin, the fifth B-vitamin I have covered in this series, thing looked much different: At high doses niacin (as nicotinic acid) will have profound effects on your glucose metablism and whether those are beneficial or bad for you may eventually depend on the timing of your niacin supplements.

Vitamin A (Retinol) & Glucose Management | Part VIII of the "There is More To Glucose Control Than Low Carb"- Series. Plus: Retinol's Effects on Pancreas, Liver, Muscle and Fat

Vitamin A is not exactly known for being an anti-diabetes vitamin. If anything people will associate it with skin health... and SuppVersity Readers probably with anti-cellulite treatments | learn more In the previous installments of this series I have addressed many of the "usual suspects" everyone associates with non-carbohydrate dependent improvements in blood glucose management. In today's installment of this series I will now take a look at an important vitamin of which only few would expect that it is in any way involved in glucose management: Vitamin A - real, pre-formed retinoic acid, not beta-carotene. In view of the misleading news about the "involvement" of retinol binding proteins in the etiology of the diabesity epidemic and the bullocks about the negative effects of vitamin A on vitamin D, the vast majority of health junkies all over the web will probably associate high vitamin A intakes with insulin resistance, not -sensitivity. You can l...

Vitamin C & Glucose Management | Part VI of the "There is More To Glucose Control Than Carbohydrates"-Series. Plus: The Limits & Limitations to Oral Ascorbic Acid Supplements

Foods over pills! Not forks over knives ;) Over the past weeks I have written so much about the anti-adaptational effects of ROS-scavengers that I probably don't have to mention the impressive (for some people shocking results) of the 2009 study by Ristow et al. with the telling title: "Antioxidants prevent health-promoting effects of physical exercise in humans" (Ristow. 2009) to underline that not everything is gold that comes in yellow packages and is labeled w/ vitamin C. Much contrary to the yellow, orange, red, green and blue natural vitamin C sources from the super- or farmers-market, by the way. Before I get lost in the hormesis debate, I do yet want to adopt to a more general, non-exercise related perspective to check, if the impairment of exercise-induced improvements in insulin sensitivity is the only interaction between vitamin C and glucose metabolism.
