- Supplements Studied:1
Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
Essential for both male and female fertility; critical for early fetal development; reduces neural tube defects
Supports egg and sperm quality; improves mitochondrial function in gametes; studied in both sexes
Supporting Stack (Tier 2)
Supports hormone production and egg/sperm membrane health; anti-inflammatory
Supports reproductive hormone function; deficiency linked to infertility in both sexes
Essential for sperm production and quality; supports ovulation in women
Supports sperm motility and energy; studied for male subfertility
Antioxidant; essential for sperm motility; supports thyroid function important for fertility
Particularly helpful for PCOS-related infertility; improves egg quality and ovulation
Antioxidant; supports sperm membrane health; may improve endometrial lining
May improve ovarian reserve in women with diminished response; use under medical supervision
How It Works
Subfertility (reduced fertility) affects about 1 in 6 couples trying to conceive. It can be caused by female factors (ovulation problems, tubal issues, endometriosis), male factors (low sperm count/motility), or a combination. In many cases, no clear cause is found.
COMMON CAUSES:
Female factors:
Male factors:
WHEN TO SEE A SPECIALIST:
LIFESTYLE FACTORS that affect fertility:
* Folate is essential for both partners and critical for preventing neural tube defects.
* CoQ10 supports egg and sperm quality by improving mitochondrial function.
* Myo-Inositol is particularly helpful for women with PCOS.
* Zinc, Selenium, and L-Carnitine support male fertility.
* DHEA may help women with diminished ovarian reserve (use under medical supervision).
Expected timeline: Egg and sperm development takes about 3 months, so supplements should be started at least 3 months before trying to conceive. Effects may take several months to manifest.
