Enhances hair growth, fullness, shine and texture including eyelashes and eyebrows, and promotes nail growth and strength
Supports memory, cognition and brain and cardiovascular health
Assists with deeper, sounder sleep and circadian reset
Boosts autophagy, which declines with age, and promotes cellular renewal
Spermidine is a potent polyamine, known for inducing autophagy, which is the body's cellular renewal and recycling process that slows as we age.
The effects of spermidine supplements on humans have been studied and have shown to support cognition and heart health, promote hormonal balance and improve hair growth and fullness (including eyelashes and eyebrows), and strengthen nails.
Epidemiological studies have correlated higher spermidine levels with longer life.
The gut biome and our tissues produce 2/3 of our body's spermidine. This is known as 'endogenous production'. The final third comes 'exogenously' or externally from our diet.
As we age, spermidine production in our tissues and gut biome begins to fall, reducing autophagy, and therefore cell renewal.
Stem cells lose their ability to divide as we age, and we are unable to replace cells that have migrated, differentiated, or died. As a result, we show outward symptoms of aging, such as gray hair.
As cells age, their mitochondria start to lose their integrity due to the build-up of oxidative stress. Compromised mitochondrial function leads to a number of adverse events, such as increased apoptosis induction, that correlate with aging.
Shortened telomeres are associated with aging cells that are senescent. As cells divide, the telomere ends of chromosomes get shorter. Eventually, telomerase gets silenced and the telomeres are too short for cells to divide.
As cells are exposed to environmental factors, they are subject to changes in their genome through epigenetic mechanisms. Such changes accumulate over time and have been correlated with the decline observed in aging cells.
As cells age, they show an increase in self-preserving signals that result in damage elsewhere. Altered extracellular communication with aging contributes to decline in tissue health.
As cells age, environmental stresses add up and mechanisms responsible for maintaining proper protein composition start to decline. Proteins lose their stability, autophagic processes start to fail, and misfolded proteins accumulate.
