Potassium-Magnesium Aspartate, an Overlooked Endurance Enhancer? Acute 100% Increase in Time to Full Exhaustion

Written by | published on

1952, Italian Fausto Coppi is drenched with water by a fan during the golden years of the Tour. Question: Can the topical application of K & Mg do the same magic? Answer: That's very  unlikely, ... What sounds like a supplement producer was trying to sell his product with a sponsored study is, in fact, the gist of a 1968 study from the Departments of Clinical Physiology and Internal Medicine at the venerable Karolinska Institute  in Stockholm, Sweden (Ahlborg. 1968). The authors' conclusion that "[a]fter administration of potassium-magnesium-aspartate [KMgA] the capacity for prolonged exercise increased about 50 per cent" (Ahlborg. 1968) can thus not be discarded as marketing babble. And, before we decide whether it's too good to be true, I'd suggest we take a closer look at the way the data was generated before we either (a) discard it as outdated or (b) get totally excited for nothing. Mineral water will contain some K and Mg, too - and it will...

Potassium: Your Heart and Vasculature Will Love it! Meta-Analyses Show: Supplements Work, but Ain't Necessary

Written by | published on

Foods, not supplements should be your go-to potassium source. You've read about the importance of adequate potassium intakes and the lack of potassium (esp. in relation to sodium, where only 10% of the US adults meet the Na:K ratio the WHO recommends to reduce your overall mortality risk) in our diets at the SuppVersity , before ( read more about potassium deficit s). You've also learned that potassium supplements can be necessary during very low-calorie diets where they prevent the paradoxical induction of insulin resistance ( read more about potassium and insulin resistance ). What you haven't read yet, however, is the number Tang et al. put on the effect of supplemental potassium on vascular function in their recent review and meta-analysis in the  International Journal of Cardiology  (Tang. 2016). Learn more about potassium (K) in previous SuppVersity articles: Potassium vs. Diet-Inducded Insulin Resis. In the Lime Light: The Ill Effects of Low K Intake...

To Prevent Insulin Resistance Potassium Supplementation is a Must on Protein-Modified Fast W/ Out Fruits & Veggies

Written by | published on

You don't need supplemental K, well... unless you are on a protein modified fast without fruits and veggies ;-) The 1984 study by Norbiato et al. is not a very recent, but it's probably a very important study which was set up to investigate "the role of potassium deficiency in the development of glucose intolerance during caloric deprivation" (Norbiato. 1984). Or, put simly, the scientists wanted to know if a low potassium level may promote insulin resistance and modify or is modified in response to dieting (in this case protein-modified fasting). In the study, two groups of subjects were studied. The "normal" group consisted of ten subjects, who were 27-45 years old and whose body weights ranged from 89 to 115% of the "ideal body weight". The "obese" group  group consisted of twenty subjects aged 21-48 years who were 70%-131% overweight. Learn more about the health effects of food: Pasta "Al Dente" = Anti-Diabetic ...

Prevalent Nutrient Deficiencies in the US: More Than 40% are Vitamin A, C, D & E, Calcium or Magnesium Deficient and >90% Don't Get Enough Choline, Fiber & Potassium

Written by | published on

Choline, fiber, potassium, this meal has everything US citizens don't eat. The latest re-examination of data from the 2001-2008 National Health and Nutrition Examination Survey (NHANES) reveals: " A substantial proportion of the adult population (over 40%) had inadequate intakes of vitamin A, vitamin C, vitamin D, vitamin E, calcium, and magnesium." (Agarwal. 2014) While many studies have examined the differences in micronutrient intakes in various population subgroups, very few studies have compared the micronutrient intake status of overweight and/or obese with that of normal weight adults. A highly relevant distinction as it turns out. Learn more about the health effects of food: Pasta "Al Dente" = Anti-Diabetic Vinegar & Gums for Weight Loss Teflon Pans Will Kill You!

Common Nutrient Deficiencies, Their Health Consequences and How You Can Fix Them - Part 1: Potassium Deficiency, Bone & Protein Loss, Stroke, Heart Disease & High Mortality

Written by | published on

The fact that many Americans don't get enough of the "non-salt" electrolytes (calcium, magnesium, potassium) is also due to the fact that mineral water is still an exotic beverage in the US. A recent paper by scientists from the Council for Responsible Nutrition in Washington (Wallace. 2014) says: Large portions of the population had total usual intakes below the estimated average requirement for vitamin A (35%), vitamin C (31%), vitamin D (74%), vitamin E (67%), choline (92%) and vitamin K (67%), as well as potassium (100%), calcium (39%) and, of course, magnesium (46%) - and that despite the fact that more than 50% of the US citizens consume a multivitamin and -mineral supplement of which probably 90% believe that it would balance their dietary shortcomings. Reason enough to take another look at the possible health consequences and ways to fix these deficiencies by increasing the intake of certain foods or supplements.
