Longevity Supplements That Actually Work in Humans

Introduction to Longevity Supplements

In this video, the speaker discusses longevity supplements and their effects on human health and lifespan. The focus is on supplements that have shown some evidence of increasing life expectancy, reducing mortality, or improving hallmarks of aging in humans.

Metformin as a Longevity Supplement

• Metformin is a diabetic drug with a long track record of improving life expectancy in patients with diabetes.

• It helps alleviate symptoms and complications of diabetes and reduces the risk of cancer in diabetic individuals.

• However, its effects on life expectancy in non-diabetics are conflicting, with some studies suggesting longer lifespans for metformin users but not conclusively proven.

• There is limited evidence to support the use of metformin off-label for longevity purposes in non-diabetic individuals.

Glycine and NAC Combination

• Glycine and NAC (N-acetylcysteine) have been studied extensively in human clinical trials.

• These supplements have shown promising results in reducing hallmarks of aging and improving functional outcomes related to aging in elderly individuals.

• They increase glutathione levels, which leads to various positive effects such as improved muscle strength, gait speed, metabolic profile, lower inflammation levels, and better antioxidant events.

• While glycine supplementation has been shown to increase lifespan in animals, there are no studies demonstrating lifespan extension in humans. However, they do show potential for reversing or reducing hallmarks of aging.

Vitamin D Supplementation

• Vitamin D supplementation has been associated with reduced mortality in human adults.

• A systematic review including 159 randomized clinical trials found that vitamin D3 supplementation decreased mortality among elderly individuals living independently or in institutional care.

• Another meta-analysis from 2014 showed that optimal serum concentration of vitamin D (40 to 60 nanomoles per liter) was associated with the lowest risk of prostate cancer and overall mortality.

• However, both low and excessively high levels of vitamin D can be detrimental to health. It is important to maintain optimal normal vitamin D levels.

Conclusion

• The evidence for longevity supplements in humans is limited, but some supplements have shown potential benefits in increasing life expectancy, reducing mortality, or improving hallmarks of aging.

• Metformin has a track record of improving life expectancy in diabetic individuals.

• Glycine and NAC combination has shown positive effects on reducing hallmarks of aging in human clinical trials.

• Vitamin D supplementation has been associated with reduced mortality, but maintaining optimal levels is crucial.

The Role of Vitamin K in Mortality Risk

In this section, the speaker discusses the role of vitamin K in mortality risk and its association with healthy foods.

Vitamin K and Mortality Risk

• Healthy foods, especially leafy greens and vitamin K2-rich foods like egg yolks, liver, and natto, contain vitamin K.

• Vitamin K2 enables better utilization of vitamin D and helps store it in bones rather than keeping it in the bloodstream where it could become calcified.

• Dietary intake of vitamin K is associated with reduced cardiovascular disease, cancer, and mortality.

• There is no evidence that supplemental vitamin K is associated with reduced mortality or heart disease.

Glucosamine: Benefits for Cardiovascular Health

This section focuses on the benefits of glucosamine for cardiovascular health.

Glucosamine and Reduced Mortality

• Use of glucosamine is associated with a 39% reduction in all-cause mortality and a 65% reduction in cardiovascular disease mortality.

• Glucosamine has anti-inflammatory and autophagic effects.

• While evidence may be somewhat limited, taking glucosamine can benefit joint health and potentially have positive effects on overall longevity.

Glycine, Vitamin D, Metformin, Rapamycin: Safe Supplements

This section highlights safe supplements such as glycine, vitamin D, metformin, and rapamycin.

Safe Supplements for Longevity

• Glycine and vitamin D are safe supplements with a long track record of safety. They have little to no side effects.

• Metformin and rapamycin are prescription drugs that should only be taken under medical supervision. Consultation with a doctor is necessary before considering these drugs for longevity purposes.
