No Cardiovascular Health Benefits Result from Most Common Dietary Supplements

It is well known within the research community that dietary supplements as a class achieve next to nothing for basically healthy people, those lacking any specific deficiency or medical condition that might cause that deficiency. In fact the evidence strongly suggests that some supplements, antioxidants for example, may even be modestly harmful over the long term. This scientific consensus has to compete with the marketing budget of the supplement industry, which seems to be doing fairly well for a community focused on selling a mix of largely useless and mildly harmful products. So studies such as this one continue to roll out, and perhaps one day there will be meaningful change as a result, but I'm not holding my breath. Treatment and prevention of micronutrient deficiencies with vitamins and minerals in the last two-and-a-half centuries are among the most dramatic achievements in the history of nutritional science. However, interest in micronutrients has shifted recently from prevention of classic deficiency states to prevention of possible subclinical deficiencies and promotion of overall health and longevity using supplemental vitamins and minerals (supplement use). Here, the data are less clear, but supplement use is widespread. Using the National Health and Nutrition Examination Survey data (1999 to 2012) on 37,958 adults, it was estimated that supplement use was high in 2012, with up to 52% of the population taking supplements. Multivitamins were taken...

In this study, we demonstrate that irrespective of the derivation of CD8+ CD45RA+CD27- T cells, these primed cells exhibit a unique highly inflammatory secretory profile characteristic of the SASP, and we also provide evidence that ADAM28 can be used as a functional marker of senescence in CD8+ T cells. Furthermore, we show that the secretory phenotype in CD8+ CD45RA+CD27- T cells is controlled through p38 MAPK signalling, which contributes to age-associated inflammation.

Abstract Context: Physical activity (PA) is associated with 25-hydroxyvitamin D [25(OH)D] levels. Both are associated with atherosclerotic cardiovascular disease (ASCVD), but their joint association with ASCVD risk is unknown. Objective: To examine the dose-response between PA and 25(OH)D, and to assess effect modification of 25(OH)D and PA with ASCVD risk. Design: Cross-sectional and prospective study using Poisson and linear regression. Setting: Community-dwelling Atherosclerosis Risk in Communities cohort. Participants: 10,342 participants free of ASCVD, with moderate/vigorous intensity PA a...

We examined 698 people with a mean follow‐up of 7.3 years. Serum 25(OH)D3 was inversely associated with the risk of cardiovascular morbidity and mortality: HR 0.98 [95% confidence interval (CI) 0.96 to 0.99, P = 0.001]. Compared with the fourth quartile (Q4) [25(OH)D3> 61.8 nmol/l], HR (with 95% CI) was 3.46 (1.60 to 7.47) in Q1 [25(OH)D3

There continues to be interest in understanding the role of vitamin D in the pathogenesis, epidemiology and prevention of cardiovascular disease (CVD). In fact vitamin D deficiency has been associated to an increased risk of developing CVD given to the relationship between low vitamin D levels and obesity, diabetes mellitus, dyslipidaemia, endothelial dysfunction and hypertension. However, although vitamin D has been identified as a potentially important marker of CVD, the mechanisms through which vitamin D deficiency leads from endothelial dysfunction to myocardial infarction and stroke are not fully understood.

l F Abstract Vitamin D, a molecular precursor of the potent steroid hormone calcitriol, has a crucial functions and roles in physiology and pathophysiology. Tellingly, Calcitriol has been shown to regulate various cellular signalling networks and cascades that have crucial role in cancer biology and diagnostics. Mounting lines of evidences from previous clinical and preclinical investigations indicate that the deficiency of vitamin D may contribute to the carcinogenesis risk. Concomitantly, recent reports suggested that significant reduction in the cancer occurrence and progression is more likely to appear after v...

Conclusions What is the sweet spot for vitamin D and longevity? All studies are in agreement: 40-50 ng/ml. If I had a (working) magic wand, I'd make this range much broader - but, there it is. Since it is narrow, let's cover the main sources of Vitamin D and figure out how you can get to the exact target. Sources of vitamin D We get vitamin D from supplements, sun and food--and in that order for most of us. Food Considering that we need thousands of IU's of vitamin D per day, food doesn't have that much. Some of the highest sources have only a few hundred units. Food sources of Vitamin D:[13] Salmon: 4 oz. = 500 IU...

This study teaches us that poor wound healing and wrinkling and sagging that occur in aging skin share similar mechanisms." Reduced cell cohesiveness of outgrowths from eccrine sweat glands delays wound closure in elderly skin Human skin heals more slowly in aged vs. young adults, but the mechanism for this delay is unclear. In humans, eccrine sweat glands (ESGs) and hair follicles underlying wounds generate cohesive keratinocyte outgrowths that expand to form the new epidermis. Our results confirm that the outgrowth of cells from ESGs is a major feature of repair in young skin. Strikingly, in aged s...

The advice you’re getting from your doctor, the TV and even the Surgeon General is so wrong, it’s scary. They’re all busy telling you to stay out of the sun. But Swedish researchers recently discovered that nonsmokers who avoid the sun have a life expectancy similar to smokers who spend a lot of time in the sun. Staying out of the sun is as dangerous as smoking.1 It doesn’t surprise me. I tell all my patients sunlight exposure is essential to our health because it is the best source of vitamin D… possibly the most important nutrient we know of. Mainstream medicine still doesn’t recogni...
