Homocysteine Resist
Item Catalog Number: 02121
60 vegetarian capsules
Benefits at a Clance
This formulation combines vitamins B2 (riboflavin), B6 (pyridoxal 5’-phosphate), B12 (as methylcobalamin) and folate as L-5-methyltetrahydrofolate (L-5-MTHF).
Folate helps maintain homocysteine levels within the normal range, which promotes cardiovascular health.1,7,8 Folate supports neurotransmitter synthesis as well, which is an essential part of cognitive health.9 People with healthy homocysteine levels have a greater chance of maintaining healthy cognitive function.10,11
But not everyone’s body can utilize traditional folate supplements. Research shows that a large part of the population cannot convert folate to its bioactive 5-MTHF form (L-5-methyltetrahydrofolate), leaving many vulnerable to low blood folate levels (and higher-than-desired homocysteine).12 So Homocysteine Resist delivers 8500 mcg of 5-MTHF in each capsule.
Vitamin B6 also facilitates neurotransmitter synthesis, as well as amino acid and lipid metabolism.9 Traditional forms of B6 must be converted to pyridoxal 5'-phosphate before your body can use it, but Homocysteine Resist contains 100 mg of pyridoxal 5'-phosphate that’s ready to work right from the start.9
The body naturally converts vitamin B2 (riboflavin) to its riboflavin-5'-phosphate form, which it then uses for energy production.13 Vitamin B12 supports nerve cell growth and heart health by helping to maintain healthy homocysteine levels already within normal range.14,15 And methylcobalamin is the form of B12 biologically active in your brain.16

Take one (1) capsule daily with food, or as recommended by a healthcare practitioner.
Trimethylglycine (TMG) 1000mg provides methyl groups to convert homocysteine to methionine. L-5-MTHF 1000mcg active folate reduces homocysteine by 25-40% in all genetic types. Clinical research demonstrates measurable benefits within 4-8 weeks of consistent daily use.
Methylcobalamin B12 1000mcg supports homocysteine metabolism through methionine synthase. P-5-P B6 100mg active form converts homocysteine to cysteine via transsulfuration. Results vary by individual but are generally noticeable within the first month.
This supplement is generally well-tolerated with other nutritional supplements. Consult your healthcare provider if taking medications to ensure proper coordination of care.
Many users notice initial benefits within 2-4 weeks. For comprehensive results, research indicates optimal benefits emerge after 8-12 weeks of consistent supplementation.
Follow label directions for optimal results. Taking with food may enhance absorption. Consistency is important—establish a daily routine for best outcomes.
Results: Trimethylglycine (betaine) supplementation at 3-6g daily reduces plasma homocysteine by 10-20% through direct remethylation to methionine.

Results: L-5-MTHF at 400-1000mcg daily reduces homocysteine by 25-40% more effectively than folic acid, especially in individuals with MTHFR C677T polymorphism.

Results: Combined methylated B vitamins (L-5-MTHF, methylcobalamin, P-5-P) reduce homocysteine by 30-50% and improve cardiovascular outcomes by 10-15%.

Results: Vitamin B6 as P-5-P at 50-100mg daily supports transsulfuration pathway, reducing homocysteine by 15-25% through conversion to cysteine and glutathione.
