The system
More than just supplements
01
The Full Approach
This isn't one product. It's a structured approach to improving your health and sperm health in the months leading up to conception.
02
More Than Supplements
Supplements form the foundation — but they're only one part of the picture. Your environment, habits, and daily routine all play a role in your overall health over time.
03
Built As A Complete System
Each part of Cabin is designed to work together — giving you a clear, structured approach to follow, rather than leaving you to figure it out alone.
The 90-day system
How it works
month by month
1
Month One
Build the foundation
Start your daily supplement routine and introduce the lifestyle tools. Your body begins receiving the nutritional support it needs consistently for the first time.
- Start 4-capsule daily supplement routine
- Switch to cotton boxers daily
- Read the lifestyle and nutrition guides
- Begin using EMF shield and blue light glasses
2
Month Two
Stay consistent
The habits become routine. Sperm cells that will matter in 30–60 days are developing right now — consistency during this period is what makes the difference.
- Maintain daily supplement routine
- Environmental habits fully in place
- Nutrition and lifestyle adjustments embedded
3
Month Three
Complete the cycle
Sperm takes 74–90 days to fully develop. By the end of month three you've supported an entire sperm development cycle — from the very beginning to the point that matters most.
- Full 90-day sperm development cycle supported
- Every factor addressed — nutrition, heat, environment
- Ready to try when the time is right
What's inside
Everything in the bundle
The Complete Bundle includes everything below — each item chosen to address a different factor that influences male reproductive health in the months before conception.
Nutrition
The Fertility
Complex
Fertility starts internally.
Many of the nutrients that support sperm production, count, and motility are difficult to consistently get in optimal amounts through diet alone.
The fertility complex provides targeted support across the full 90-day cycle — helping your body function properly during the period that matters most.
Every ingredient is included with purpose, carefully selected and dosed for effective daily use within 4 capsules.
L-CarnitineSupports sperm motility and energy metabolism
1044mgCoQ10Supports cellular energy and sperm function
150mgZinc PicolinateContributes to normal fertility and hormone balance
25mgVitamin CProvides antioxidant support for sperm health
500mgVitamin EProvides antioxidant support for sperm health
200mgSiberian GinsengSupports energy, resilience, and vitality
300mgVitamin D3Supports hormone regulation and overall wellbeing
4000 IUSeleniumSupports normal sperm development
100μgFolic AcidSupports cell division and overall health
400μgCopper CitrateSupports energy metabolism and cell protection
2mg
Heat management
100% Cotton
Boxers
Sperm production is highly sensitive to temperature.
Most standard underwear is tight and made from synthetic materials, which can increase heat in the area over time.
Loose-fit cotton boxers use natural, breathable fabric to help maintain a cooler, more optimal environment.
Medium (M): fits waist 30–34 in (81–86 cm)
Large (L): fits waist 36–38 in (91–97 cm)
Large (L): fits waist 36–38 in (91–97 cm)
Guidance
Lifestyle &
Nutrition Guides
Knowing what to do matters as much as doing it.
The guides provide clear, structured direction on lifestyle and nutrition — helping you follow the system properly and stay consistent over the full 90-day period.
E-books are sent via email upon purchase.
Environment
EMF Blocking
Shield
Everyday habits like using a laptop on your lap can increase exposure to heat and electromagnetic radiation.
While often overlooked, these exposures can affect the environment in which sperm is produced.
The EMF shield creates a simple barrier during use, helping reduce unnecessary exposure.
30cm x 40cm — fits most laptops up to around 16 inches.
Sleep & recovery
Blue Light
Blocking Glasses
Exposure to blue light in the evening can disrupt your natural circadian rhythm — making it harder for your body to properly wind down and recover.
Blue light blocking glasses help protect your sleep cycle, supporting the hormonal environment needed for reproductive health.
Hydration
BPA Free
Bottle
BPA is a chemical commonly found in plastics that can leach into food and water.
It has been linked to changes in male reproductive health, including sperm quality.
This BPA-free bottle helps reduce that exposure while supporting consistent hydration as part of a more controlled daily routine.
750ml capacity · BPA-free · Stainless steel · Durable, everyday use

Men who prepared
the right way
"
★★★★★
"Started taking Cabin purely for fertility support, but noticed other benefits I wasn't expecting — more consistent energy through the day and just generally feeling more on top of things. Didn't anticipate that but it's been a welcome bonus."
"
★★★★★
"I hadn't really considered how much the male side contributes to pregnancy until I looked into it properly. Cabin helped it make sense and made it easy to actually do something about it."
"
★★★★★
"My partner had been taking her prenatal vitamins for about 3 months before she mentioned I should probably be doing something too. Found Cabin, the 90 day thing made sense and it's easy enough to stick to."
"
★★★★★
Wasn't sure where to start with any of this. Cabin made it feel straightforward — clear ingredients, clear reasoning, simple routine. Three weeks in and I feel like I'm actually doing the right things rather than just hoping for the best.
