1. Supports energy production: B-Complex vitamins are essential for converting food into energy, making this product a great addition to your daily routine. The inclusion of Metafolin L-5 MTHF, a bioactive form of folate, further aids in energy metabolism.
2. Promotes healthy nervous system: The B vitamins in this product play a crucial role in maintaining a healthy nervous system. They help in the production of neurotransmitters, which are responsible for sending signals between nerve cells and promoting proper brain function.

The Active Ingredient Is: Folate (Metafolin L-5-MTHF)

Folate is a B vitamin involved in ordinary cellular function and the generation of DNA and red blood cells. This formula uses Metafolin L-5-MTHF, the active form of folate, which is easily absorbed in the body.

This form is sourced as Metafolin L-5-MTHF and is included in vegetarian capsules to support bioavailable folate intake. This combination may support normal methylation and cellular health processes integral to everyday vitality.

What Does Folate Do?

Folate is involved in normal energy metabolism and DNA synthesis, contributing to the functioning of the nervous system and cognitive processes. Its bioactive form crosses barriers more readily, supporting efficient folate utilisation in the body.

The primary benefit is enhanced folate activity through Metafolin L-5-MTHF, with other B vitamins in the blend supporting overall metabolism and neural health as part of a balanced nutrient network.
