Fertility, sperm/egg quality, pregnancy support
Reproductive health is one of the most nutrient-sensitive systems in the body. Zinc concentrates in semen and is essential for testosterone synthesis + sperm motility. Folate (B9) prevents neural-tube defects and supports DNA methylation during gametogenesis. Omega-3 DHA builds the developing fetal brain. Vitamin D and selenium support hormone synthesis. Deficiencies in any of these load-bearing nutrients show up as subfertility long before they cause symptoms elsewhere.
