Seeking Health's Methyl B12 with L-Methylfolate offers a strong dose of bioavailable folate and vitamin B12, presented in a delicious, easily-absorbed lozenge. This formula targets multiple aspects of health, primarily focusing on enhancing methylation, regulating homocysteine levels, and boosting energy production.

What’s inside
True Folate (Featuring methylfolate - L-5-MTHF): vital for methylation, energy production, and cognitive health.
Bioavailable B12 (Including a blend of 'Adeno' and 'Methyl' forms): supports energy metabolism and optimizes folate utilization in methylation processes. B12 also aids in supporting healthy methylation and addressing MTHFR genetic mutations. Lastly, B12 facilitates the regulation of homocysteine levels for cardiovascular health and general well-being.
