Women’s health spans the entire lifecycle from childbearing age, pregnancy, perimenopause, to postmenopause. Interwoven with multiple challenges such as hormonal fluctuations, methylation metabolism, chronic low-grade inflammation, and vascular care, single ingredients struggle to meet full-stage demands, making precise ingredient pairing the core direction of women’s nutrition development.
Many people focus on active ingredients for regulating the endocrine system while often overlooking the foundational nutritional support of one-carbon metabolism. Among numerous women’s nutritional ingredients, calcium L-5-methyltetrahydrofolate (active folate calcium) has long broken through the conventional perception of being “only for preconception and pregnancy use.” Without requiring MTHFR enzyme conversion, it directly participates in methylation regulation and homocysteine level modulation, building a solid nutritional foundation for vascular homeostasis, emotional nerve health, and metabolic balance, making it an indispensable baseline active ingredient for women’s full-cycle health maintenance.
Recently, Hygieia’s Femifolin® L-5-Methyltetrahydrofolate Calcium won the Shoushiliao “Innovative Ingredient Certification”. Powered by the self-developed Zymevolver® enzyme engineering platform, it has built a diverse women’s health ingredient matrix covering endocrine regulation, metabolic support, and anti-oxidation/anti-inflammation: Femifolin® L-5-Methyltetrahydrofolate Calcium, S-Equol, and Insopro™ D-Chiro-Inositol, synergizing through synthetic biotechnology to provide high-quality raw material support for women’s full-cycle health solutions.

Folic acid (vitamin B9) participates in critical physiological activities such as human one-carbon metabolism, cell division, and homocysteine regulation. It is an indispensable nutrient for women during preconception and early pregnancy, as well as a core micronutrient supporting women’s full-cycle health.
With the continuous iteration of precision nutrition research, public consumer awareness has shifted significantly, moving market demand from “whether to supplement folic acid” to “which type of folic acid better matches individual metabolic traits.”
Traditional synthetic folic acid requires multiple liver reduction steps (first generating tetrahydrofolate) and methylation metabolism after ingestion to finally produce physiologically active L-5-methyltetrahydrofolate. Large-scale population epidemiological studies have confirmed that MTHFR C677T/A1298C gene polymorphism variations, personal constitution, and long-term dietary habits significantly reduce folate conversion efficiency. Over 78% of the Chinese Han population carries relevant mutation sites, universally facing bottlenecks in folate metabolic conversion.
Multiple 2024 international clinical controlled trials indicate that simply supplementing synthetic folic acid fails to improve folate and homocysteine indicators in genetically variant populations.
In contrast, Hygieia’s Femifolin® L-5-Methyltetrahydrofolate Calcium is the calcium salt form of natural active folate, which can be directly absorbed and utilized by the human body without relying on MTHFR enzyme metabolic conversion.
Embryonic safety tests and reproductive cohort studies have confirmed that this active folate form carries no risk of unmetabolized folic acid accumulation. It can rapidly elevate red blood cell folate levels in mutation populations and steadily downregulate homocysteine, making it suitable for long-term supplementation by preconception and pregnant women, perfectly matching current personalized precision nutrition R&D demands and establishing differentiated core scientific advantages.
The Zymevolver® platform is an integrated R&D and manufacturing base built by Hygieia deeply cultivating the field of synthetic biology: through three core modules—high-throughput enzyme screening, site-directed mutagenesis modification, and intelligent fermentation process regulation—it directionally optimizes catalytic enzyme activity and specificity, substantially enhancing target product conversion rates.
The entire technology system holds complete independent intellectual property rights, with flexible process scale-up capabilities, seamlessly connecting small-scale R&D to ton-scale mass production lines to ensure long-term stable supply for domestic and international clients.
Relying on its proprietary Zymevolver® enzyme engineering evolution platform, Hygieia prepares Femifolin® L-5-Methyltetrahydrofolate Calcium using green bioconversion technology, continuously optimizing purity, impurity control, finished product stability, and mass production consistency.
In addition to molecular technology innovation, the company features comprehensive supporting services, adaptable to tablets, soft capsules, solid beverages, special dietary powders, and other dosage forms, providing full sets of technical data on toxicological safety, stability, and efficacy validation to help downstream brands shorten R&D cycles and achieve stable mass supply.
