The Swimmers team is excited to announce the release of an enhanced version of our Swimmers Antioxidant Formula for male reproductive health. The redesigned formula incorporates customer feedback and up-to-date medical science.  It is easier to take and remains the most evidence-based male fertility supplement available.

The new Swimmers Antioxidant Formula contains 8 different ingredients. Six of those ingredients (Vitamin C, Vitamin E, Folate, Zinc, L-Carnitine, and CoQ10) are backed by the very strongest “Level A” evidence. Each of these was selected by our medical team because it has been shown to positively impact male fertility in multiple randomized controlled clinical trials.  The remaining two ingredients in the new formula are lycopene and Vitamin D, each of which is backed by science and has been demonstrated to effectively improve sperm health in at least one clinical study.  

Researchers at the University of Miami recently developed and published a scoring system to rate male fertility supplements according to clinical and scientific evidence of a positive effect on sperm quality or pregnancy. Using that methodology, the original Swimmers Antioxidant Formula ranked #1 out of 18 evaluated popular male fertility supplements with a composite score of 3.67. The upgraded Swimmers Antioxidant Formula remains #1 by an even wider margin, with a score of 4.13.
