overview

High Potency, Balanced Comprehensive B-Complex*

  • METHYLATED B-COMPLEX

    This advanced B-complex formulation includes eight essential B vitamins along with choline, inositol, and biologically active folate as 5-MTHF for optimal methylation. Methylation is a critical biochemical process that converts homocysteine into methionine and cysteine, supporting cardiovascular and nervous system health.*

  • OVERVIEW

    B vitamins are essential for the body’s ability to convert food into cellular energy. These water-soluble vitamins are absorbed in the small intestine and metabolized in the liver into their active coenzyme forms. Acting as coenzymes in the Krebs cycle, they are vital for the production of adenosine triphosphate (ATP), the body’s primary energy currency. Moreover, B vitamins like folate, B6, and B12 play pivotal roles in methylation, a process crucial for converting homocysteine into methionine and cysteine. Methylation influences DNA repair, gene expression, and overall mental and physical health.*

  • FUNCTIONS OF EACH ESSENTIAL B VITAMIN

    Thiamine (Vitamin B1)


    Thiamine is a key cofactor in A TP production within the Krebs cycle and is required for metabolizing fats, proteins, and carbohydrates. Modern diets often lack sufficient thiamine due to the over-processing of grains. Research from randomized, double-blind, placebo-controlled trials indicates that high-dose thiamine supplementation may also support balanced blood sugar levels.1*


    Riboflavin (Vitamin B2)


    Riboflavin serves as a precursor for flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), critical for energy production and antioxidant activity. Riboflavin deficiency can lead to oxidative stress and impaired energy production. Studies suggest that maintaining optimal riboflavin levels can help promote healthy blood pressure, especially in genetically predisposed individuals.2*


    Niacin (Vitamin B3)


    Niacin, transformed into NAD and NADP in the body, is a cofactor in mitochondrial energy production. It supports oxidation-reduction reactions and promotes cardiovascular health, with substantial evidence demonstrating its role in maintaining healthy cholesterol levels.3*


    Vitamin B6


    With involvement in over 100 enzymatic reactions, B6 is vital for lipid metabolism, neurotransmitter production, immune function, and hormone regulation. Studies show that higher dietary intake of B6 supports cardiovascular health and enhances lymphocyte activity, promoting immune function in older adults.4,5*


    Folate (5-MTHF)


    Folate is indispensable for DNA synthesis, methylation, and mitochondrial energy metabolism. Unlike folic acid, which requires enzymatic conversion, 5-MTHF is bioactive and readily utilized by the body. This ensures better folate absorption, particularly in individuals with suboptimal enzyme activity. Folate also supports neural tube development during pregnancy and overall cellular function.*


    Vitamin B12


    Essential for fat and carbohydrate metabolism, protein synthesis, and mitochondrial energy regulation, B12 is primarily found in animal-based foods. This nutrient supports neurological health, mood, and energy production. V egan and vegetarian diets often lack adequate B12, making supplementation critical.6*


    Biotin


    Biotin is vital for the metabolism of fats, carbohydrates, and proteins, playing a key role in cellular processes and macromolecule synthesis. It is also associated with promoting healthy hair strength and growth6,7*


    Pantothenic Acid (Vitamin B5)


    Pantothenic acid and its active form, CoA, are essential for synthesizing fatty acids, phospholipids, amino acids, and steroid hormones. Approximately 95% of CoA resides in mitochondria, underscoring its role in energy production. Research highlights pantothenic acid’s ability to support tissue repair and regulate blood lipids.8,9,10*


    Choline Bitartrate


    Although not a B vitamin, choline is critical for forming cellular membranes and lipoproteins. It also synthesizes acetylcholine, a neurotransmitter vital for brain and muscle function. Choline supports cognitive health and cellular integrity.*

  • What is methylation, and why is it important?

    Methylation is a natural biochemical process that takes place throughout the body. It contributes to many functions that help maintain normal cellular activity and overall wellness.

    This process is involved in areas such as:

    • Gene activity: Supports normal regulation of how genetic information is expressed
    • Cellular maintenance: Supports processes involved in maintaining healthy cells
    • Neurotransmitter activity: Supports the body’s production of brain chemicals involved in mood and focus
    • Metabolic pathways: Participates in processes related to nutrient metabolism and normal cellular function
    • Homocysteine metabolism: Supports the conversion of homocysteine into amino acids such as methionine
    Some people have certain genetic variations that may affect how efficiently the body converts specific forms of folate. Supplements that provide folate as L-5-MTHF offer a form the body can use directly.

  • What is a methylated B-vitamin complex?

    A methylated B-complex is a B vitamin supplement that contains active, bioavailable forms of certain vitamins, including methylfolate (L-5-MTHF) and methylcobalamin (vitamin B12). These forms can be used by the body directly rather than requiring additional conversion steps.

    Methylated B-complex formulas are designed to support normal methylation processes, which are associated with cellular activity, neurotransmitter balance, and energy metabolism.

  • What does methylated B-complex do?

    A methylated B-complex supports several normal functions involved in everyday wellness, including:

    • Cellular energy metabolism
    • Nervous system function
    • Neurotransmitter activity related to mood and focus
    • Homocysteine metabolism and cardiovascular wellness
    • Immune function and general well-being
    • Maintaining adequate intake of essential B vitamins

  • How is InfiniWell’s Methylated B-Complex different from standard B-complex vitamins?

    Many traditional B-complex supplements use forms such as folic acid or cyanocobalamin, which the body must convert before they can participate in normal metabolic pathways.

    InfiniWell’s Methylated B-Complex provides eight essential B vitamins in bioavailable forms, including L-5-MTHF and methylcobalamin. These forms can participate directly in the body’s natural biochemical processes.

    The formula also includes additional nutrients that support normal cellular activity:

    • L-5-MTHF (methylated folate) and methylcobalamin (B12): Support methylation and homocysteine metabolism
    • Vitamin B6 and vitamin B2: Support energy metabolism and normal nervous system activity
    • Choline and inositol: Support cell membrane structure and normal neurotransmitter activity

    Because the formula uses active coenzyme forms, it may be particularly helpful for individuals whose bodies convert certain B vitamins less efficiently.

    If you are unsure whether a methylated B-complex supplement is appropriate for you, consider speaking with a qualified healthcare professional before adding it to your routine.

  • Is this supplement good for energy?

    B vitamins participate in the body’s energy metabolism. They help convert carbohydrates, fats, and proteins from food into adenosine triphosphate (ATP), the molecule cells use to store and transfer energy.

    By providing active forms of these nutrients, InfiniWell’s Methylated B-Complex supports normal metabolic processes involved in cellular energy production.

    The formula does not rely on stimulants such as caffeine.

  • How does this supplement support cognitive wellness?

    Studies indicate B vitamins participate in the production and regulation of neurotransmitters such as serotonin, dopamine, and norepinephrine. These brain chemicals are associated with mood, attention, and mental clarity.

    Maintaining adequate intake of these nutrients supports normal nervous system activity and cognitive wellness.

  • How does this supplement support cellular energy and metabolism?

    B vitamins function as cofactors for many enzymes involved in energy metabolism. These enzymes participate in pathways that convert nutrients from food into usable cellular energy.

    The formula includes active coenzyme forms that participate in normal metabolic pathways associated with cellular activity and energy production.

    Additional nutrients such as choline and vitamin B5 also support metabolic processes involved in the use of fatty acids and other nutrients.
