It involves transferring small chemical units called **methyl groups**, which help regulate numerous essential functions. ### What does methylation do? Healthy methylation supports: * DNA synthesis and repair * Gene regulation * Homocysteine metabolism * Neurotransmitter production * Red blood cell formation * Cellular function Because these processes happen continuously, adequate intake of nutrients involved in methylation is important. ### Which nutrients support methylation? Several B vitamins contribute to normal methylation, including: * Vitamin B2 (Riboflavin) * Vitamin B6 * Vitamin B9 (Folate) * Vitamin B12 Other nutrients such as betaine (TMG) and choline also participate in related metabolic pathways. ### Why do some people choose methylated vitamins? Some individuals may have reduced ability to convert conventional folic acid into its active form due to genetic variations such as MTHFR. For these individuals, supplements containing L-5-MTHF and methylcobalamin may be preferred under the guidance of a healthcare professional. ### Does everyone need methylated vitamins? No. Most healthy adults obtain sufficient B vitamins from a balanced diet. However, active forms may be useful for certain populations, including older adults, vegetarians, people taking certain medications, or those with increased nutritional needs. If you're unsure whether methylated vitamins are right for you, speak with your healthcare professional. #### Learn More If you're looking for a bioactive B-complex formulated with all eight essential B vitamins in active forms, explore Decode Age MethylAge-B™.
