How can the effect of spermidineLIFE® be measured?

Your question regarding the measurability of the effects is unfortunately somewhat difficult for us to answer... since spermidineLIFE is a natural food supplement there are strict legal restrictions regarding statements about the potential benefits. However, as with most supplements, many of the known effects are anecdotal information reported by users or learned through studies focused on one specific effect, like hair growth or glucose utilization in mice. This difficulty also has to do with the different benefits people experience and feel. It seems that the benefits of autophagy are manifested in many ways depending on where the body chooses to use the recycled energy.
