Applying science to increase healthspan
Genetic variants, or polymorphisms, are the common changes that can affect gene function a little bit. These changes make us all unique – from traits like hair color or eye color to the things that ‘run in the family’, like …
Mitochondrial dysfunction and elevated oxidative stress are part of the root cause of aging. With poor mitochondrial function, cells can’t perform at an optimal level, leading to an increase in ROS (reactive oxygen species). Oxidative stress, due to an increase …
Inflammaging: What is it and how can you prevent it Inflammaging refers to low-grade, sterile, chronic inflammation that increases with age and can contribute to health declines, age-related diseases, and frailty. The exact causes are still unclear, but one theory …
In aging, muscle mass declines, as does physical performance. Stopping age-related muscle loss is important for healthspan and overall wellness in aging. For example, more muscle mass may protect you from falls and from osteoporosis. Hydroxy-β-methylbutyrate (HMB) is a metabolite …
To me, the idea of living longer is only appealing without the prospect of age-related neurodegeneration. Healthspan is my goal, and the prevention of Alzheimer’s is a major focus. For decades, research on Alzheimer’s has focused on amyloid-beta plaques and …
A recent phase II clinical trial showed significant improvements in cognitive scale scores for Alzheimer’s patients. Importantly, these are natural supplements that are readily available. Plus, it is rare to see a clinical trial with positive results in Alzheimer’s after …
Genetic studies, especially large genome-wide association studies, can be informative when looking at what is really important for healthspan. Essentially, these types of studies look to see which genetic variants are linked to outcomes — real-life people, real outcomes, and …
Spermidine is a biogenic amine with many potential anti-aging benefits, ranging from extending healthspan to improving vaccine efficacy in older adults. I’ll dig into the research on the topic, explore the clinical trials, and explain why increasing spermidine can sometimes …
New research on COVID-19 shows the important role of cellular senescence in the high mortality rates in the elderly. Elderly people are much more vulnerable to the flu, respiratory infections, and sepsis than middle-aged or younger adults. We all know …
Kind of like pornography, we all know aging when we see it. There is a specific point when suddenly someone looks old. Like they have crossed some invisible threshold, moving from healthy and older into the twilight area at the …
Alpha-ketoglutarate is a key molecule produced in your cells. Recently, research studies have shown that it may play a key role in healthy aging, including increasing healthspan and lifespan. What is alpha-ketoglutarate? Alpha-ketoglutarate (αKG) is a molecule that cells produce. …
A recent study on sleep and dementia points out (once again) that sleep is essential for good health in aging. The study found that decreased sleep, such as 6 hours or less per night, during your 50s and 60s increases …
I read a lot of studies on health and genetics, and I keep finding research on the mineral lithium popping up. Topics such as circadian rhythm dysfunction, Alzheimer’s disease, telomere length, type 2 diabetes, and obesity…all linking to lithium? The …
TNF-alpha (tumor necrosis factor alpha) is a proinflammatory cytokine upregulated in aging. TNF-alpha acts as a signaling molecule in our immune system and is important in our innate immune response. But chronically elevated TNF-alpha is one cause of the diseases …
Cellular senescence is a natural process that stops the reproduction of cells. While senescence happens throughout life, in aging, an accumulation of excess senescent cells seems to be at the heart of many age-related diseases. What is cellular senescence? Senescence …
