Studies have pointed to Parkinson’s patients having significantly increased levels of spermidine. Therefore, why would a further supply of spermidine in the form of a supplement bring about any improvement?

Unfortunately, the specifics of spermidine amount and expression in individuals with Parkinson's Disease is going to be above my knowledge of the supplement. There are many reasons why spermidine count in individuals can be higher than normal. For example, a stress response of the body could also be responsible for the production of spermidine as cell protection. In any case, it should be stressed that clinical studies on the effect of spermidine in Parkinson's patients are lacking. Therefore, no recommendation can be made to take spermidine supplements, nor should the study mentioned be interpreted as an indication of a negative effect.
