Or maybe both? In this vid I cover this controversial supplement and give science based advice. An extensive article that examines the study mentioned in this video on the effects of ARA on strength and muscle mass can be read HERE!
However, whey is a complex protein which leads to various questions regarding this biologically active protein. Some of this confusion has stemmed from the marketing efforts of various companies competing for sales in a very competitive market. Some of the confusion stems from a simple misunderstanding of the science of whey.
This Q&A will attempt to address some of the most common questions regarding whey as it applies to some of the major differences between types of whey, such as whey concentrates and whey isolates and other common sources of confusion. For in-depth information on whey and its many potential health benefits, read the “50 Shades Of Whey”
Q1:“What are the essential differences and advantages/disadvantages of each type of whey protein? Isolate, concentrates?”
DHEA (dehydroepiandrosterone) is most known for being a pro-hormone which in the body gets converted to testosterone and estrogen. It is a long held view that DHEA exerts all its effects via conversion to testosterone and estrogen. However, recent studies show that DHEA also has several interesting non-hormonal actions…
In this vid I cover the essential points I covered in a lengthy article by the same name: absorption, solubility – as a key factor in absorption – and a new technology that improves solubility.
For those in the supplement industry especially, you’ll want to watch this vid!
Will has previously mentioned DHEA as it relates to hormonal effects and health promotion:
When it comes to health promotion and longevity, DHEA is a supplement which deserves more attention than it is getting.
DHEA levels (the main circulating form of DHEA in the bloodstream is DHEAS) decrease approximately 80% between ages 25 and 75 year.[1, 2] This large decline in DHEA has led to interest in the possibility that aging related DHEA deficiency may play a role in the deterioration in physiological and metabolic functions with aging, and in the development of chronic diseases.
In support of this, it has been reported that DHEA level is negatively correlated with mortality and risk of developing cardiovascular disease (CVD) (i.e. lower DHEA(S) levels are associated with higher mortality and CVD risk).[3-5] More recently it has been found that a steep decline or extreme variability over time in DHEA(S) levels is associated with higher mortality, more so than baseline DHEA(S) levels.
Aging not only reduces DHEA(S) levels, but also results in an increase in arterial stiffness [7, 8], which is an independent predictor of cardiovascular disease (CVD) risk and mortality.[9-11] It has been reported that DHEA levels are inversely associated with arterial stiffness (i.e. lower DHEA levels are associated with increased arterial stiffness. [7, 12, 13] Therefore, it is possible that DHEA replacement could reduce arterial stiffness, and thereby contribute to reduction in CVD and mortality…
As with fashion, what gets sold for supplements are often many decades old, and have been re marketed to people as new and “cutting edge.” . Case in point, Deer Antler products. Been around longer than I have yet made a big return to the market recently. It didn’t perform as advertised then, and it doesn’t now. Yet, millions of bottles sold sadly.
How do you “break into” the supplement industry? What experience and educational background do you need? In this vid I cover the truth behind how different people get into the supplement industry.
“None of the studies reported a statistically signiﬁcant effect of ﬁsh oil treatment relative to placebo. Further analysis showed no relationship between body weight change with intervention duration, or n-3 dosage, nor any funnel effect with study sample size. This analysis does not support the hypothesis that daily n-3 oil supplementation reduces body weight and BMI in the overweight and obese.”
First, drawing such a definitive conclusion based on data from only 4 studies, that are heterogeneous, is misleading. Second, the studies didn’t provide enough information to allow the meta-analysis to adjust for factors that might abrogate the fat loss effect of the long-chain omega-3 fatty acids EPA and DHA, found in fatty fish and fish oil.
Nutritional supplement companies want people to believe the products they sell are made by them in pharmaceutical grade facilities using the best possible ingredients using the latest science,
and designed people with qualifications to formulate such products. The actual truth is nothing like that. In this episode of BrinkZone radio I reveal how the vast majority of nutritional supplements are
Actually produced from start to finish with an industry insider (me!) breaking it down and giving the facts the slick marketing fails to show.

Here’s my “take home” on this latest study causing all the hoopla that found an association to “fish oil” and prostate cancer. For those who want to real nitty gritty on this study, see article by Dr. Lopez HERE.
