INTRODUCING METHYL

Methylation is your body’s biochemical powerhouse—fueling DNA repair, detoxification, brain function, energy production, and immune defense. But stress, poor diet, toxins, and viruses can weaken this essential process, leaving you fatigued, inflamed, and vulnerable.

METHL delivers proprietary, bioavailable vitamins to boost methylation, enhance absorption, and fortify your body’s defense. Fuel your body the way nature intended.

What To Look Out For In Your Vitamins

SHOP VITAMINS

  • Plastic Bottles

    Plastic bottles can leach harmful chemicals like BPA into your vitamins, compromising purity. Glass preserves potency, ensures freshness, and is 100% non-toxic and recyclable—better for your health and the planet. ♻️

  • Cyanocobalamin

    Cyanocobalamin is a cheap, synthetic B12 with poor absorption and unnecessary toxins. METHL uses Methylcobalamin, the pure, active form for better energy and brain function—no fillers, no compromises.

  • Non Methylated Vitamins

    Non-methylated vitamins require conversion and are harder to absorb, METHL uses proprietary, methylated vitamins, the active, ready-to-use forms for superior absorption, energy, and overall health.

  • Harmful Fillers

    Most vitamins use cheap fillers like Magnesium Stearate and folic acid, which are hard to absorb and may cause toxin buildup. METHL uses only bioavailable, methylated nutrients for clean energy and better absorption—no harmful additives.
