4th Folic — Quatrefolic 600mcg Tablets (30s)
4th Folic delivers Quatrefolic® — the 4th generation of folate — in an easy-to-take 600mcg tablet. Unlike standard folic acid, Quatrefolic is already in its biologically active form ((6S)-5-methyltetrahydrofolate glucosamine salt), meaning your body can use it directly without needing to convert it first.
Key Features:
- 4th generation Quatrefolic® — more advanced than 3rd generation calcium-salt folate
- High water solubility, long-lasting stability, and improved bioavailability
- Active, "finished" folate — no metabolization required by the body
- Suitable for individuals with MTHFR gene variations, who may struggle to convert regular folic acid
- Supports normal red blood cell formation and helps reduce tiredness and fatigue
- Supports folate levels during preconception, pregnancy, and lactation
Who is it for?
Commonly used by women planning pregnancy or in early pregnancy to support fetal neural development, individuals with folate deficiency, people with MTHFR gene variants, and those wanting a highly bioavailable active folate supplement.
Directions for Use:
Take one tablet daily, or as directed by your physician.
Pack Size: 30 Tablets
