Staying fit and aging healthy!

The quest for a longer and healthier life has led to exciting discoveries in the science of aging. One of the leading figures in this field is Dr. David Sinclair, a renowned scientist and author of the book "Living Longer Healthier; The Revolutionary Science Behind Healthy Aging Over 100." His groundbreaking research has offered insights into the biological mechanisms behind aging and led to promising perspectives on healthy aging. This article explores David Sinclair's essential discoveries and Insidetracker's crucial role in measuring blood levels to help us optimize our well-being.



The World of David Sinclair

Dr. David Sinclair is a pioneer in research on the biology of aging. His work has sharpened our understanding of the aging process at the cellular level. By investigating how NAD+ (nicotinamide adenine dinucleotide) acts as a coenzyme in cells, Sinclair has gained important insights into how NAD+ can help slow aging and promote a healthy longer life.

The Power of NAD+

Sinclair's research has shown that NAD+ plays a crucial role in maintaining cellular energy and overall health. As we age, NAD+ levels in our bodies decrease, which can lead to an acceleration of the aging process and an increased risk of age-related diseases. Increasing NAD+ levels, for example through NAD+ precursors such as NMN, could potentially benefit our health and vitality as we age, according to Sinclair's research.

Insidetracker: A Window to Optimal Wellness

Measuring blood levels is invaluable in giving us insight into our health and guiding us toward a longer and healthier life. InsideTracker, an innovative health tool, offers an in-depth look at our biochemistry through personalized blood tests. By accurately measuring levels of vital biomarkers, InsideTracker helps individuals reach their health goals and maximize their lifespan potential.

David Sinclair's discoveries shed new light on the aging process and offer hope for longer, healthier lives. His work on NAD+ metabolism and healthy aging has paved the way for a revolution in our approach to aging. With the support of pioneering tools such as Insidetracker, we now have the ability to optimize our health in the most personalized and informed way, thereby improving our well-being and longevity.


Question from Frank:

I once wanted to have my NAD value measured after taking six months of NMN supplement.


Dear Frank,

NAD in a blood test stands for "Nucleotide Adenine Dinucleotide." This is actually a coenzyme that plays an important role in cell metabolism and energy production in living organisms. NAD can be found in two forms: NAD+ (oxidized form) and NADH (reduced form). These molecules are involved in various biochemical reactions in the body.

In the context of a blood test, NAD can sometimes be measured to obtain information about a person's metabolic state, cellular health and energy production. It may be relevant in certain medical conditions, such as metabolic disorders.

We use Insidetracker for this:


Although NAD and NADH are important in biochemistry, the term "NAD level" is not often used as a routine blood test in medical practice. Blood tests usually focus on specific biomarkers, enzymes, hormones, blood cells and other substances that offer specific information about a person's state of health.

NMN stands for nicotinamide mononucleotide, a compound involved in the production of NAD+ in the body. NAD+ plays an important role in cell metabolism and energy production. NMN supplements are sometimes taken in the hope that they can increase NAD+ levels and thereby support health and aging processes.

Although NMN supplements are popular, evidence for their effectiveness in humans is still limited and largely based on animal studies. Because the effects of NMN and other NAD+ precursors are complex and still under investigation, there are no standard blood values specifically established to measure the effectiveness of NMN supplements.

In the scientific literature, NAD+ levels are sometimes used as an indicator to evaluate the effects of NAD+ precursors such as NMN. If you are interested in tracking the effects of NMN supplements, you might consider having your NAD+ levels measured periodically through laboratory testing. This can be complex, however, because NAD+ levels vary in different tissues and can be affected by different factors.

It is important to note that, in addition to measuring NAD+ levels, monitoring other health parameters may also be important to assess the overall effectiveness of NMN supplements. These may include:

1. Energy and fatigue levels.

2. Metabolic health, such as insulin sensitivity and blood sugar levels

3. Cell health and inflammatory markers

4. Cardiovascular health, such as blood pressure and cholesterol levels

5. Physical and cognitive performance

It is therefore advisable to monitor the success of your NMN supplements through InsideTracker.
