Overview

This supplement provides L-methylfolate and methylcobalamin, which are highly bioavailable and active forms of folate and vitamin B12, respectively. The dose of L-methylfolate is notably high, suitable for specific clinical indications such as adjunctive treatment for depression, while the methylcobalamin dose is well-researched for addressing deficiencies and supporting neurological health. The liquid sublingual delivery may enhance absorption.

Bioavailable Ingredient Forms: Utilizes L-Methylfolate and methylcobalamin, which are active and highly absorbable forms of folate and vitamin B12, eliminating the need for conversion in the body.

Targeted for Neurological Health: The combination of L-methylfolate and methylcobalamin is particularly beneficial for supporting brain, mood, heart, and nerve health due to their crucial roles in methylation processes, neurotransmitter synthesis, and homocysteine metabolism.

Optimal Methylcobalamin Dosage: The 1000 mcg dose of methylcobalamin is well-supported by research for effectively addressing vitamin B12 deficiency and supporting neurological functions.

This high dose may not be appropriate for all individuals and could lead to side effects or imbalances for those who do not have a diagnosed need for such high levels.
