The Food and Drug Administration (FDA) recently issued a warning regarding severe safety issues associated with opioid pain medications including decreased sex hormone levels (i.e., testosterone) and more. In this article, Dr. Paul Henning investigates how opioid use and sexual dysfunction may be linked.

Early research in the late 90s showed that creatine supplementation increased total body water, and that has been the widely accepted truth ever since then, but is it really true? In this article, Dr. Paul Henning looks at the total body of research to see if creatine supplementation actually increases water retention.

The effects of creatine supplementation in increasing muscle strength, lean mass, and exercise performance/muscle function are well documented, but did you know that creatine may exert powerful effects on how your brain functions too? In this article, Dr. Paul Henning explains the benefits of creatine on the brain.

We all know the benefits of exercise as it relates to heart health, strength, and muscle development, but what is often not talked about is how exercise protects our brain. In this article, Dr. Paul Henning examines the research related to exercise and brain health and how you can train to optimize mental performance.

Implementation of this simple lifestyle change surprisingly stabilizes the physiology, reduces inflammation, pain, and stress, enhances sleep, blood flow, and lymphatic/venous return to the heart, and produces greater well-being. In this article, Dr. Paul Henning dives deep on a topic many people aren't even aware of.

Human movement involves various types of muscle actions such as eccentric, concentric, and isometric contractions. It's widely known that muscles are stronger on the eccentric (lowering) part of and exercise, much less is known about how eccentric training impacts muscle growth. Today, Dr. Paul Henning investigates.

High-density lipoprotein cholesterol (HDL-C) is a well established marker and mediator of coronary heart disease (CHD), and high levels of HDL-C appear to be protective against CHD. But the question is, can resistance training enhance HDL-C regardless of body weight? In this article, Dr. Paul Henning investigates.

Protein requirements for resistance trained athletes are greater than those that don’t participate in resistance training. But is one animal-based protein source better for building muscle compared to the others? In this article, Dr. Paul Henning investigates to determine whether chicken, beef, or dairy is best.

Are you one of those people who love to combine your cardio and resistance training together? Is it more beneficial to do cardio before or after resistance training? In this article Dr. Paul Henning examines the research to determine if there is an optimal training schedule to maximize muscle.

Your brain consumes a lot of energy. In fact, the brain consumes approximately 20% of the body’s fuel intake but represents only about 2 to 2.5% of the mass. And now there is research that may explain this extreme energy consumption. Dr. Paul Henning explains more in this article.

Despite the proposed benefits of consuming a higher-protein diet to preserve muscle mass or promote muscle growth, higher-protein diets are often discouraged because of potential negative effects on kidney function. But is that really the case? In this article, Dr. Paul Henning investigates to get closer to the truth.

Many factors determine your body's ability to fight off invaders and remain healthy against the onslaught of pathogens we face each day. In this article, Dr. Paul Henning examines the available research as it relates to the impact that declining levels of growth hormone may have on your immune system.

Testosterone has multiple functions on the overall health of women. And although not in the same quantity as men, women also produce testosterone in their ovaries and adrenal glands. In this article, Dr. Paul Henning discusses the impact that testosterone has on women's bodies.

The keto diet has become increasingly popular among men looking to lose weight, but at what cost? In this article, Dr. Paul Henning looks at the keto diet and how it affects testosterone (the 'male' hormone) and cortisol (the stress hormone) in men.

Skeletal muscle is one of the most dynamic tissues of the human body and comprises approximately 40% of total body weight. But many people don't know how it impacts their health. In this article, Dr. Paul Henning explains it's functions and the impact that it has on your overall health.
