While both berberine and resveratrol are popular natural supplements, they work through distinct biological pathways to influence health outcomes. Berberine is a potent alkaloid known for activating the AMPK pathway, whereas resveratrol is a polyphenol celebrated for activating sirtuins, proteins linked to longevity.

Research has revealed that the plant alkaloid berberine affects multiple cellular pathways, including those linked to aging and metabolism. This has prompted the question: does berberine activate sirtuins, a family of proteins known for their role in longevity and metabolic regulation?

According to the National Institutes of Health, over one-third of the global population experiences sleep problems, highlighting the need for effective solutions. When considering nutritional aids for rest, many ask, "Should I take resveratrol before bed?" The answer depends on individual goals, age, and how your body responds to this potent polyphenol.

In recent cellular studies, the active form of vitamin D, $1,25(OH)_2D$, was found to significantly increase nicotinamide adenine dinucleotide (NAD) levels in fat cells. This discovery reveals a surprising and indirect pathway through which vitamin D may support cellular metabolism and combat age-related decline by influencing the NAD-dependent sirtuin pathway.

Research has shown that NAD+ levels can decline by 50% every two decades. This makes understanding how to boost this vital coenzyme crucial, and many wonder: does exercise increase NAD+? The science points to a clear and positive connection, particularly through the activation of key metabolic pathways.
