Who this is for

If you and your partner want a serious nutritional foundation, this was formulated for you.

Fertility Phix is built for both partners, and works across natural conception and assisted reproductive techniques (IVF, IUI, ICSI). The formula was designed from the peer-reviewed literature on the nutrients that matter for reproductive wellbeing: chosen specifically, dosed at the levels the evidence supports, in the forms the body can use (e.g. methylated folate for people with MTHFR variants).

Egg and sperm cycles each run roughly 12 weeks. That's why we recommend both partners take Fertility Phix daily for at least three months before trying to conceive, and continuing during the journey itself.

Used by clinicians. Trusted by people trying to conceive.

    Since I began taking Fertility Phix I've experienced several positive changes. A significant increase in my energy levels. I had a fertility scan today and the results showed that my eggs are growing beautifully. I truly believe that Fertility Phix is making a substantial and positive difference in my pregnancy journey.
