DHEA supplementation in older adults helps reverse arterial aging

  • Published in DHEA

When it comes to health promotion and longevity, DHEA is a supplement which deserves more attention than it has been 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.[6]

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 in older adults could reduce arterial stiffness, and thereby contribute to reduction in CVD and mortality...

Blood Cholesterol Testing - don't let the routine standard lipid panel fool you!

 

The mere word “blood cholesterol” strikes horror in many people. We have been indoctrinated since the well-known Framingham Study in the 1980s that the higher the blood cholesterol level, the higher the risk of heart disease.[1-3] However, much has been discovered in medical research since then. 
 
Today there is compelling evidence showing that strict reliance on the traditional cholesterol test – aka the standard lipid panel - that is routinely run in primary care, can falsely indicate that you're fine, even when you aren't. 
 
Here you will find out what to look for when interpreting your cholesterol levels...

Can Age-Related Declines in Testosterone Levels be Prevented or Reversed?

It is well-documented that testosterone levels decline with age in men.

After the age of 40 years, total testosterone decreases on average -4 ng/dL ( -0.124 nmol/L) per year [1] or 1.6% per year [2], and bioavailable testosterone by -2 to 3% per year. [2]

In older men (over 60 years of age), the average rate of decrement in total testosterone levels has been found to be 110 ng/dL every decade.[3]

However, the relative contributions of changes in health and lifestyle to that decline have not been adequately evaluated. A notable study was set out to investigate this...

OBJECTIVE:

The objective of this study was to establish the relative importance of aging, health, and lifestyle in contributing to the testosterone decline in aging men.[4]

Does Testosterone Therapy Really Increase the Risk of Heart Attack?

A few days ago, Jan 29th 2014, a controversial study [1] was published showing that men aged 65 years and older, had a two-fold increase in the risk of heart attack in the 90 days after filling an initial TT

prescription, regardless of cardiovascular disease history. Among younger men below 65 years of age with a history of heart disease, the study reported two to three-fold increased risk of MI in the 90 days following an initial TT prescription. 

This study has stirred up heated discussions and media headlines. Let's dissect it and look under the hood...
