Cumulative Research Suggests Coffee Prolongs Life by 1.8 Years

Worldwide, people consume about 2 billion cups of coffee a day, and a new review associates drinking this caffeinated beverage regularly with an average of 1.8 years added to lifespan.

With over 246 million data points, obtained from 108 participants, scientists show that we rapidly age around 45 and 60. 

Stanford researchers find that our biological age accelerates during mid-life and retirement age. 

Combining Micronutrients with NAD+ Precursors to Maximize Their Effects

Mixing nutraceutical molecules with nicotinamide adenine dinucleotide (NAD+) precursors may synergistically boost and maintain NAD+ levels while bolstering their longevity-promoting benefits.
