Fermeast™ SP
Fermeast™ SP is a dried sake yeast containing 0.2 wt% or more of spermidine(SPD). It is also rich in yeast-derived nutritional components (vitamins, amino acids, minerals, etc.).
SPD is a Key to Antiaging.
Spermidine(SPD) is a type of polyamine. Polyamines are present in almost all living organisms, from microorganisms to plants and higher animals, and are components that play an important role in cell proliferation in living organisms. Putrescine, spermidine(SPD), and spermine are known as typical polyamines in the human body.
The concentration of SPD in the body decreases with aging (Fig. 1), but it can be supplemented by diet. SPD is abundant in traditional Japanese foods such as fermented foods and is an ingredient with abundant eating experience. Fermeast™ SP assists in dietary intake of SPD.
