You told us first.
Science agreed.
For years, our community shared what they noticed: more energy, better moods, and less fatigue. We listened. Then we ran the clinical studies. Here’s what we found.
Mood improved by nearly 45% by cycle 3, the largest improvement of any parameter in the clinical study.
Vitamin D3 levels increased by 30.8%, a key nutrient for reproductive health and pregnancy wellness.
Satisfaction with sex life improved by nearly 47% over three months, the largest gain of any parameter in the For Him clinical study.
Energy was the first thing to improve for both men and women, and it kept building across all 3 months.

What Changed
Key Findings*
Vitamin D levels significantly increased
A ~27–30% rise in Vitamin D and Vitamin D-3 respectively; a clinically meaningful result tied to reproductive health and postpartum wellness.
Mood showed the greatest improvement of any measured parameter by cycle 3
Mood improved by 45% from baseline; the largest single gain across the entire study. 62.5% of participants agreed their mood had improved, and all 8 well-being parameters showed statistically significant improvement by cycle 3.
Energy up, fatigue down — starting from cycle 1
75% of participants reported more energy and less fatigue by cycle 3. Energy was among the earliest participant-reported changes within the very first cycle.
Nearly 3 in 4 women experienced less bloating
Bloating frequency dropped by more than 33% over the course of the clinical study; a statistically significant result. And it was one of the first improvements women noticed: 65% agreed they experienced less bloating as early as cycle 1.
1 in 2 women experienced less vaginal dryness
Vaginal dryness frequency dropped by nearly 37% over three months; the largest symptom frequency reduction in the clinical study. This is a symptom many women experience but rarely talk about, and it showed statistically significant improvement starting from cycle 1.
9 in 10 women wanted to keep taking WeNatal For Her after the clinical study ended
87.5% said they would like to continue using the product. 81% said they would recommend it to a friend or family member. When the science and the experience line up, that's when you see numbers like these.
Key Findings*
Energy was the earliest and strongest change
Energy levels improved by nearly 29% within the first month; the most notable early finding in the clinical study. By month 3, the improvement had reached 31%, making energy one of the most consistent wins across the full three months.
Libido and sexual well-being improved significantly
Libido scores rose by more than 41% over three months, a statistically significant result. More than half of participants agreed their libido and sexual arousal had increased by month 3. This was one of 8 out of 9 parameters that showed significant improvement by the end of the clinical study.
Satisfaction with sex life improved 47% by month 3
Of all nine parameters measured, satisfaction with sex life showed the greatest improvement; a 47% increase from baseline. Results built progressively across all three months, which aligns with how nutritional support for male fertility is designed to work.
Getting and maintaining an erection both improved
Frequency of achieving an erection during sexual activity improved by more than 28% over three months, a statistically significant result. Ease of maintaining an erection improved by more than 30%. Both were significant findings in the For Him clinical study, starting as early as month 1.
Muscular strength and endurance improved across all 3 months
Muscular strength and endurance scores improved by 18% over three months; a statistically significant result that held consistent at every measurement point. For men focused on overall vitality alongside fertility, this was one of the most stable findings in the clinical study.
Results built over time, and men noticed
6 of 9 parameters improved significantly within the first month. By month 3, 8 of 9 had improved. 66% of participants said they wanted to keep using the product. 57% said they would recommend it to family and friends. The pattern is consistent: the longer men took WeNatal For Him, the more they felt it.

Clinical study progression
The results didn’t just appear.
They built over time.
Results from the clinical studies built month after month. Participants who stayed consistent saw the most improvement, with gains continuing across the study period.
Self-reported Energy up 28% for men. 6 of 8 well-being measures already improved for women.
Self-reported Libido up 40% for men. Energy levels showing their strongest gains yet for women.
Self-reported Mood up 45% for women. Satisfaction with sex life up 47% for men. 8 of 9 parameters improved.
Why It Matters
Fertility support isn’t just about one moment — it’s the whole picture. Optimal nutrient status helps support your body’s natural processes across every stage of the fertility journey.
These clinical studies showed that real, consistent use of WeNatal supplements was associated with improvements in nutrient status and participant-reported measures of energy, mood, libido, and overall well-being. The clinical study results help reinforce what our community already knew: when foundational nutrition is supported, people can feel the difference.
