What is Vitamin B9 for?

Vitamin B9 covers both folic acid (the synthetic form) and folate (the natural form found in food). It is essential for DNA synthesis and cell division. It also plays a role in red blood cell production, amino acid metabolism (including homocysteine) and healthy nervous system function. It is particularly recommended for women who are pregnant or planning a pregnancy, as it contributes to reducing the risk of neural tube defects in the developing fetus.

Benefits and signs of deficiency

The benefits of B9 span fertility, cardiovascular health (lowering homocysteine), mental wellbeing (mood, nervous fatigue) and anemia prevention. Signs of deficiency include persistent fatigue, breathlessness, paleness, digestive issues and irritability. The Quatrefolic® (L-methylfolate) and 5-MTHF forms are the most bioactive, also suited to people with an MTHFR gene variant.

Why choose our selection in Paris

At Herba Barona, 10 rue Théophile Roussel in the 12th arrondissement, we select our vitamin B9 supplements on precise criteria: bioavailability, purity, and no unnecessary additives. We have chosen the most absorbable forms (Quatrefolic®, 5-MTHF) rather than synthetic folic acid, for maximum effectiveness across all profiles. Our team is available to advise you Tuesday to Saturday, 9:30am-6:30pm, easily reached via Ledru-Rollin or Bastille metro.
