Your 90-Day Fertility Timeline
Sperm take about 90 days to develop from start to finish. Every day, your body is building the next generation of sperm, and each stage has unique nutritional needs. That's why we built SwimClub to support every stage of that cycle — so when the moment comes, you've done everything you could.
Day 0–16
Building the Foundation
Day 0–16
Building the Foundation
What happens
Every sperm starts as a stem cell in the testes. During these first few weeks, cells rapidly divide and copy their DNA, laying the foundation for healthy sperm development.
Why these nutrients matter
This early stage requires energy and the nutrients needed to support normal cell division. SwimClub includes CoQ10 to support cellular energy production, zinc to support normal reproductive function, and methylfolate (MagnaFolate® Pro), the biologically active form of folate, to support healthy DNA synthesis and methylation.
Day 17-30
Shaping the Genetic Blueprint
Day 17-30
Shaping the Genetic Blueprint
What happens
As sperm continue developing, they undergo a specialized process that reduces their genetic material by half. This is a normal part of sperm formation and helps create each sperm’s unique genetic blueprint.
Why these nutrients matter
During periods of rapid cellular development, antioxidant support becomes increasingly important. SwimClub pairs methylfolate with N-acetyl cysteine (NAC) to help support healthy cellular function and protect against oxidative stress.
Day 31-50
Building the Engine
Day 31-50
Building the Engine
What happens
Developing sperm begin forming their tail and the mitochondria that will eventually power movement.
Why these nutrients matter
Movement requires energy. That’s why SwimClub includes L-carnitine, which supports normal energy metabolism, along with CoQ10 to support mitochondrial function. Omega-3 DHA also provides an important structural building block for healthy cell membranes.
Day 51-64
Refining Structure
Day 51-64
Refining Structure
What happens
Sperm continue to mature, developing their characteristic shape while streamlining their internal structure.
Why these nutrients matter
This stage places a greater emphasis on membrane health and antioxidant protection. SwimClub includes Vitamin E, lycopene, and selenium, nutrients selected for their roles in protecting cells from oxidative stress and supporting normal reproductive health.
Day 65-90
The Final Stage
Day 65-90
The Final Stage
What happens
During the final weeks, sperm complete their maturation and continue developing the characteristics needed for normal function.
Why these nutrients matter
The final phase of development relies on continued nutritional support. SwimClub provides L-carnitine, Omega-3 DHA, Vitamin D3, and spermidine to support healthy sperm maturation, cellular energy, and overall reproductive wellness.
The Four Parameters
All four parameters matter — and your partner's journey deserves every advantage you can give it. A high count with poor motility won't get the job done. Strong motility with DNA fragmentation can lead to early pregnancy loss. SwimClub is the only supplement formulated to improve all four — simultaneously.
Our formula supports spermatogenesis at the cellular level to increase sperm count & production.
Targeted With
We target the root of poor motility by boosting energy production in sperm, which protects them from oxidative stress and improves flexibility. Over 3 months, clinically-informed nutrients work together so sperm swim stronger, straighter, and longer.
Targeted With
We address abnormal morphology by protecting sperm membranes, improving their structural integrity, and supporting healthy sperm development from the start. Over 3 months, clinically informed nutrients work together to refine sperm shape, enhance viability, and boost fertilization success.
Targeted With
We address DNA fragmentation with a multi-antioxidant approach that neutralizes reactivity and regenerates defenses, protecting DNA. Over 3 months, clinically-informed nutrients work together to reduce damage and enhance reproductive outcomes.

11 Clinically-Dosed Ingredients in One Daily Sachet
No filler. No proprietary blends. Each ingredient is present at a dose that matches or exceeds the clinical evidence.
Your sperm's main energy source. CoQ10 powers the tiny motors in each sperm cell that drive movement, and protects them from everyday cellular damage.
Acts as a shield for sperm cell membranes. Helps protect the outer layer of each sperm from breaking down, keeping them structurally intact and functional.
The antioxidant that gives tomatoes their color — and one of the most studied nutrients for male fertility. Embeds directly into sperm to neutralize damage before it starts.
Helps your body produce glutathione — its own master antioxidant. Works from the inside out to protect sperm DNA and improve overall sperm quality.
More than a bone vitamin — D3 plays a direct role in testosterone production and sperm function. Most men are deficient, and low levels are linked to poor sperm quality.
One of the most important minerals for male reproductive health. Supports sperm production, healthy testosterone levels, and the structural integrity of sperm DNA.
The active form of folate your body can actually use — important because up to 40% of men have a genetic variation that prevents them from processing regular folic acid. Supports healthy sperm DNA.
A naturally occurring compound found in sperm itself. Supports cellular renewal and longevity in sperm cells — and is found in lower levels in men with fertility challenges.
A trace mineral that does two important jobs: it protects sperm from oxidative damage, and it helps form the structural backbone of the sperm tail that drives movement.
Think of it as fuel delivery for sperm. L-Carnitine shuttles fatty acids into the cell's energy factories, giving sperm the power they need to swim fast and far.
DHA concentrates in the sperm tail — literally helping it move better. EPA and DHA together create a healthier environment for sperm to thrive.
What 90 Days Can Actually Change
Real improvements, measured in real men who committed to the full 90-day protocol. This is what showing up looks like.
Concentration
The number of sperm per milliliter of semen. Higher concentration increases the odds of fertilization. Normal is considered above 16M/mL.
Sperm Count
The total number of sperm in a sample. More sperm means more chances for one to successfully reach and fertilize an egg. Normal is considered above 39M.
Motility
The percentage of sperm that are moving. To fertilize an egg, sperm need to swim — and swim well. At or above 42% is considered normal.

“I’ve spent my career studying male fertility and what I see today is alarming: sperm quality is declining at a rate we can’t ignore. That’s why I partnered with SwimClub to develop the first sperm performance supplement based on decades of research and clinical experience.
Most supplements are built on generic formulas. SwimClub is different. It’s formulated to target the root causes of suboptimal sperm health, using bioactives at clinical levels sourced from the best manufacturers in the world.”
