Skin aging is a natural and inevitable process. Scientists are exploring ways to reverse aging or at least slow the process. But, as of now, reversing the aging process is not a reality.

What is Super Trimix?

Erectile dysfunction (ED), or the inability to get and sustain an erection, affects nearly 18 million US men.1 This represents nearly half of all men aged 40 and up.2 Even more surprising, about 26% of men seeking ED treatment are under the age of 40.3  Many effective treatment options for ED exist, yet many men choose not to try them. When researchers analyzed the insurance claims for 6.2 million men, only one-fourth of men diagnosed with ED filled their prescriptions.4 Treatment costs,...

What Is Brain Fog and How to Beat It

Brain fog is not a diagnosable medical condition. Instead, it is a constellation of symptoms affecting thinking and memory. Many people have experienced temporary brain fog. We all have those days when we lose track of what we are doing, can’t remember where we put our keys and phone, repeat ourselves when giving instructions, or miss an appointment on our calendar. If you are experiencing brain fog, you may notice you are constantly jotting notes on your phone, a major change from when...

What Happens When a Man’s Testosterone is Low?

Up to five million men in the United States have low testosterone. Unfortunately, aging is a major risk factor for testosterone decline. After the age of 30, testosterone drops by about 1% per year. When testosterone levels fall below 300 nanograms per deciliter (ng/dl) in a man with symptoms consistent with low testosterone, this is referred to as male hypogonadism. The prevalence of hypogonadism increases with aging, obesity, diabetes, and other metabolic and age-related conditions.  Restoring...

Future Anti-aging Technology: Is Age Reversal Really Possible?

If we accept aging as a fact of life and inevitable, then there is nothing we can do to slow or even stop the process. However, considering the possibility that aging has a cause means there is the potential to identify the cause(s) and reverse or at least mitigate its effects.  Aging is the sum of all the bodily changes that occur throughout your lifespan. How fast these changes occur and how they present themselves differs from person to person.1 Healthy lifestyle choices can slow the...

How Do Brain Health and Mental Health Intersect?

For most other body organs, it is straightforward to understand the relationship between the physical organ and the diseases that impact it. For example, when fluid fills the lungs, the fluid can become infected, and we call this pneumonia. The medical workup to diagnose pneumonia is pretty standard, as are the treatment options. So why is the relationship between brain health and mental health so murky? Our current understanding of mental illnesses is that they are conditions that negatively...

How Does Metformin Contribute to Anti-Aging?

What Are the Health Benefits of NAD+ Therapy?

Nicotinamide adenine dinucleotide (NAD+) is a universal cellular electron transporter that transfers energy from the macronutrients in foods to cells in your body where it can be used for energy. There is a lot of supporting evidence that NAD+ plays a key role in longevity and long-term cellular health.

Do You Get Shorter as You Age?

Do you get shorter as you age? Unfortunately, the answer is yes. According to researchers, the process starts after age 30. The change is not dramatic, only an inch or two, unless you have a medical condition called osteoporosis. Osteoporosis is decreased bone density. It increases your risk of hip and spine fractures. Spine and hip fractures can cause chronic pain and disability. If you are over 50, it is worth tracking your height periodically because osteoporosis doesn’t have any symptoms in...

Aging Differences by Sex and Gender

Women live longer than men. Why? There have been several theories, including estrogen protection against cardiovascular disease, a less risky lifestyle, and a willingness to seek preventative medical care. These factors may explain lifespan differences in some cases, but are unlikely to explain a persistent difference between men’s and women’s lifespans. The biggest factor affecting how men and women age and why they age differently is sex hormones. Testosterone levels slowly decline...

What Is Hormonal Aging?

The endocrine and nervous systems work together to control almost all bodily functions. The nervous system acts quickly and precisely, while the endocrine system works more slowly. Together, these two systems work to keep your body in a steady state. Endocrine glands throughout the body release chemical messengers called hormones. These hormones bind to receptors on target cells, where they produce a response. The same hormone may produce very different responses depending on the target cell with...

How Does Aging Affect the Nervous System?

Sometimes it’s hard to separate the nervous system, an organ system like any other in the body, from your sense of self. While your brain is indeed a collection of cells, just like the liver and the heart, the fact that it controls memory, personality, and feelings, not to mention movement and sensation, makes it feel like the nervous system should be elevated to a level above the other organ systems.  The nervous system, made up of the brain, spinal cord, and a network of nerve cells...
