1.Overview of Anti-Aging Ingredients
NMN (nicotinamide mononucleotide) serves as the direct precursor of NAD⁺ and exerts anti-aging effects by increasing the level of NAD⁺ in the body. NAD⁺ is a key molecule in cellular energy metabolism and DNA repair, and is involved in over 400 physiological processes. As people age, the level of NAD⁺ in the body significantly decreases, leading to the decline of cellular functions. Research conducted by Harvard University shows that supplementing with NMN can significantly enhance the mitochondrial function and muscle strength of aged mice and extend their healthy lifespan. NMN is called the "elixir of immortality" and is said to be consumed by "Li Ka-shing and Warren Buffett", making it a popular anti-aging drug. However, it has faced multiple investigations by regulatory authorities and been questioned for being a "tax on intelligence", resulting in a decline in market trust.
1.2 The Anti-Aging Properties and Effects of Ergothioneine
Melatonin is a natural antioxidant substance extracted from fungi such as mushrooms and black fungus. One of the important reasons for aging is the imbalance of redox within cells, which leads to the production of many reactive oxygen species and other substances. One of the means to combat aging is antioxidation. As an antioxidant substance, melatonin can effectively eliminate free radicals in the human body and has a unique thioketone structure, making it less prone to oxidation under physiological pH conditions and having better stability than other thiol-based antioxidants. It protects cells from oxidative damage by directly eliminating free radicals, chelating harmful metal ions, and activating the body's own antioxidant defense system (such as the Nrf2 pathway). Melatonin can also penetrate the cell membrane and enter the mitochondria to protect mitochondrial function and reduce cellular aging and apoptosis.
1.3 The Anti-Aging Mechanism and Functions of PQQ
Pyrroloquinoline quinone (PQQ) is a redox cofactor that plays a significant role in cellular energy metabolism and antioxidant defense. It promotes mitochondrial biogenesis, enhancing the production of new mitochondria, which are crucial for energy generation and overall cellular health. PQQ also exhibits potent antioxidant properties, protecting cells from oxidative stress by neutralizing free radicals.
Moreover, PQQ has been shown to support cognitive function by improving synaptic plasticity and neuroprotection, potentially aiding in memory and learning processes. Its ability to modulate signaling pathways involved in cellular repair and regeneration further contributes to its anti-aging effects.
In summary, PQQ's mechanisms involve enhancing mitochondrial function, providing antioxidant protection, and supporting cognitive health, making it a promising compound in the field of anti-aging research and overall wellness.
1.4 The Anti-Aging Benefits and Applications of Astaxanthin
Astaxanthin is a type of carotenoid with outstanding antioxidant properties. Its antioxidant capacity is 550 times that of vitamin E and it is one of the strongest natural antioxidants known. It effectively protects cells from oxidative damage by quenching singlet oxygen and neutralizing various free radicals. The unique molecular structure of astaxanthin enables it to cross the blood-brain barrier and the blood-retinal barrier, thus providing significant protection for brain and eye health. Studies have shown that astaxanthin can significantly improve skin elasticity and luster, reduce wrinkles, and enhance athletic recovery ability. Additionally, astaxanthin has positive effects on eye health, preventing macular degeneration and retinal disorders. However, the bioavailability of natural astaxanthin is relatively low, and it is usually necessary to enhance its absorption efficiency through techniques such as liposome encapsulation or esterification.
2. Comparison of Mechanisms of Action
2.1 Impact of Energy Metabolism
In terms of energy metabolism, NMN and PQQ stand out, while ergothioneine and astaxanthin mainly enhance energy metabolism efficiency indirectly by protecting cells and providing antioxidant protection.
