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

Written by | published on

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.

Funny or obscene? A woman w/ low vitamin B and thus fortified cornflakes is among the "top images" Google will show you, when you search for B-vits There is an often overlooked reason I am addressing thiamin (B1), riboflavin (B2), panthotenic acid (B5) and pyridoxine (B6) in one installment of the "There is More to Glucose Control Than Carbohydrates"-Series (read previous installments ): They are all necessary to store glycogen in the liver (Supplee. 1942). In general, a whole foods diet, as recommended in previous SuppVersity articles will easily cover the B-vitamin needs of the average sedentary and physically active individual - in spite of minimally increased requirements for B2 & B6, in particular (Manore. 2000; Woolf. 2008).

SuppVersity Science Round Up Seconds: Wheat Gluten Hydrolysates Fail, Exposure to Air Pollutants During Workout Reduces Brain Benefits, Homocysteine, B-Vitamins, Cognitive Impairment and Mortality

Before the profound weight loss (A) you don't see any of the glucose sucking and fad burning brown fat depots (black spots in B) on the neck of the in (B) 'foermerly obese', now only 'overweight' subject (also take a look at how the visceral fat in the abdominal region in (A) is actually pushing the organs upwards; img Vijgen. 2012) Those of you who have listened to yesterday's show will have noticed that despite its flow the number of things you can discuss in a 1h podcast is simply very limited, to say the least. This is also why these Friday posts are probably never going to be simple summaries of the SuppVersity Science Round Up of the day before. The same is true for today and still I decided not to use the allegedly lame logo I did for the first two installments, but provide you with some 'real science' evidence of the absence of brown adipose tissue on the obese and it's magical reappearance after shedding 100lbs+ subsequent to a ga...

B-Vitamins & Diabetes: Protective or Causative?

Written by | published on
In a very interesting study, scientists from China and Japan ( Zhou. 2010 ) found that " long-term exposure to high level of the B vitamins may be involved in the increased prevalence of obesity and diabetes in the US in the past 50 years ". At first this appears to be counterintuitive, since we have been told over and over that B-Vitamins are not only good for our health, but that we could not even "overdose" them. While the latter has been questioned for years and certainly is not the case for e.g. B6 and niacin, even the former seems questionable, if you read the results from the above mentioned study: The prevalences of diabetes and adult obesity were highly correlated with per capita consumption of niacin, thiamin and riboflavin with a 26- and 10-year lag, respectively (R2 = 0.952, 0.917 and 0.83 for diabetes, respectively, and R2  = 0.964, 0.975 and 0.935 for obesity, respectively). [...] The relationships between the diabetes or obesity prevalence and per ca...

Eat Rice, Stay Healthy!?

Written by | published on
A recently published study ( Fulgoni. 2010 ) analyzing data from 25 374 eligible participants identified as rice consumers study on the correlation of rice-eating to several markers of metabolic health showed that people who ate at least one serving of rice (white or brown) a day tend to have better health and diet parameters including less total fat, saturated fat, and added sugars; higher amounts of more than 12 essential vitamins and minerals , including iron, folate, and other B vitamins; more fruit and legumes; nearly 4 tsp (16 g) less added sugar; and 7 g less solid fats. For the 19- to 50-year-old subgroup, main results ( P < .05) also showed rice consumption associated with reduced likelihood of being overweight or obese , 34% reduced risk of high blood pressure , 27% reduced likelihood of having an increased waist circumference , and 21% reduced risk of metabolic syndrome . This, however, should not encourage you to just add one serving of rice to your bad d...

Prepare for the Winter: Get your Supply of Vitamin D Supplements

Figure 1: In Great Britain Vitamin D3 supplementation appears indicated at least in the winter month A recent study by researchers ( Webb. 2010 ) from the School of Earth Atmospheric and Environmental Sciences at the University of Manchester highlight the importance of maintaining "late-summer 25-OH(D3) levels" throughout the winter month. In their investigation among 125 white Caucasians aged 20-60 years in Greater Manchester they found: Dietary vitamin D remained low in all seasons (median 3.27 mug/day, range 2.76-4.15) while personal UV exposure levels were high in spring and summer, low in autumn and negligible in winter . Mean 25(OH)D levels were maximal in September (28.4 ng/mL; 28% optimal, zero deficient (< 5 ng/mL)), and minimal in February (18.3 ng/mL; 7% optimal, 5% deficient). A February 25(OH)D level of 20ng/mL was achieved following an average late summer level of 30.4 (25.6 to 35.2) and 34.9 (27.9 to 41.9) ng/mL in women and men, respecti...

Going Vegan? Better Get Some B-12 Lozenges

Written by | published on
While my personal credo is: "Man is made for eating meat." I respect everyone who - for ethical or whatever reasons - refuses to do so. In spite of that, a recent study by Gilsing et.al. ( Gilsing. 2010 ) found that vegetarians and vegans even more so, have a high risk of being vitamin B12 deficient. In their conclusion on the evaluation of the EPIC-Oxford cohort study, the scientists write: the results from this study show that vegetarians and vegans have much lower concentrations of serum vitamin B12 but higher concentrations of folate in comparison with omnivores. Mean serum vitamin B12 was not associated with the duration of adherence to a vegetarian or vegan diet, which may indicate that mechanisms that maintain circulating concentrations of vitamin B12 are upregulated in vegetarians and vegans. Further research into the health effects of vitamin B12 deficiency and depletion in vegans and vegetarians is warranted , and vegetarians and vegans should ensure a regular i...
