MedicalResearch.com: What is the background for this study?
Response: Small studies indicated that zinc and folic acid supplements for men might improve semen quality as both zinc and folic acid are involved in DNA transcription and have antioxidant functions. But no large-scale randomized trials have been done to assess efficacy, which is important since dietary supplements are largely unregulated, and FDA cannot regulate supplements until after they come to market. Some male fertility-targeted supplements are already among the most commonly sold supplement products, despite the lack of data to guide their use.

Dr. Lemon: Research with the supplement began in 2000, as part of my doctoral degree; we developed the supplement to try to offset the severe cognitive deterioration and accelerated aging in a mouse model we were working with in the lab. Based on aging research, five mechanisms appeared to be key contributors to the process of aging; those include oxidative stress, inflammation, mitochondrial deterioration, membrane dysfunction and impaired glucose metabolism. The criteria we used for including components in the supplement were as follows: each one of the 30 components had scientific evidence to show they acted on one or more of the above mechanisms were able to be taken orally, and were available to humans over-the-counter. Even then the hope was that if the formulation was successful, this would make it more available to the general public.
