The following benefits are each supported by peer-reviewed research on the specific nutrients found in Libré's formula: 

•       Reduces neural tube defect risk — L-Methylfolate (B9) — gold standard for pre-conception and early pregnancy neuroprotection

•       Improves oocyte (egg) quality — CoQ10 enhances mitochondrial energy in maturing eggs, reducing chromosomal error rates

•       Supports ovarian reserve — Selenium and CoQ10 protect follicular cells from oxidative stress; higher folate linked to higher antral follicle counts (PMC8714696)

•       Regulates ovulation — Vitamin D3 influences gonadotropin signalling; iodine supports thyroid-driven ovulatory cycles

•       Enhances embryo implantation — Omega-3 EPA reduces endometrial inflammation; Vitamin D3 supports endometrial receptivity

•       Reduces miscarriage risk — L-Methylfolate lowers homocysteine levels; elevated homocysteine is independently associated with recurrent pregnancy loss

•       Supports luteal phase health — Vitamin C is concentrated in the corpus luteum and supports post-ovulatory progesterone production

•       Improves assisted reproduction outcomes — Folate, CoQ10, and Omega-3s all show IVF/ART outcome improvements in meta-analyses

•       Protects eggs from oxidative damage — Selenium (as selenomethionine), CoQ10, and Vitamin C form a layered antioxidant defense in follicular fluid

•       Supports hormone balance — Magnesium bisglycinate helps regulate cortisol and supports progesterone production pathways

•       Optimises DNA methylation — B12 (methylcobalamin) + L-Methylfolate power the one-carbon cycle — critical for healthy gene expression in embryos

•       Supports thyroid function for fertility — Iodine deficiency is a leading, preventable cause of ovulatory dysfunction and early pregnancy loss

•       Helps women with MTHFR variants — L-Methylfolate bypasses the MTHFR enzyme bottleneck, making it effective where synthetic folic acid fails for ~40% of women

•       Anti-inflammatory reproductive environment — Algae-derived EPA + DHA regulate prostaglandin pathways that influence both ovulation and implantation
