Rimetil Homocysteine 400 is Dr. Caletti’s original formula with active folate 5-MTHF, methylcobalamin, betaine, vitamins B2 and B6 and zinc to support homocysteine metabolism.

 

Rimetil Homocysteine 400: Dr. Caletti’s original formula for homocysteine metabolism

Rimetil Homocysteine 400 5-MTHF is one of Dr. Caletti’s historical formulas. It originated more than thirty years ago as a pharmacy-compounded preparation and was among the first in Italy to focus specifically on hyperhomocysteinaemia, placing already active vitamin forms at the centre of the formula.

Unlike many competing products that used cyanocobalamin for years and only later switched to methylcobalamin, Rimetil has used vitamin B12 as methylcobalamin from the beginning, together with active folate 5-MTHF, betaine, vitamins B2 and B6 and zinc: the key cofactors of the homocysteine cycle in a single capsule, without unwanted excipients.

Why Rimetil is not comparable to “similar” products

  • Original Dr. Caletti formula: born as a galenic preparation for patients with hyperhomocysteinaemia when the topic was still little known; today made available by Ketozona without altering the original clinical rationale.
  • Methylcobalamin from the beginning: while many competitors used cyanocobalamin for years and later replaced it, Rimetil was designed from the start with vitamin B12 as methylcobalamin, the active form directly used in the methionine-homocysteine cycle.
  • Already active folate (5-MTHF): not simple folic acid, but 5-methyltetrahydrofolate, useful also in people with MTHFR polymorphisms that reduce folate activation.
  • Complete cofactors: B2, B6, zinc and anhydrous betaine at the maximum permitted dosage, to synergistically support the remethylation and trans-sulfuration pathways of homocysteine.

What Rimetil Homocysteine 400 contains

In a single capsule, Rimetil Homocysteine 400 contains the active cofactors of the homocysteine cycle, designed to support both genetic hyperhomocysteinaemia related to MTHFR polymorphisms and acquired forms linked to diet, medication and oxidative stress.

  • 5-MTHF – already active folate form, which does not require conversion from folic acid; particularly relevant in the presence of MTHFR variants.
  • Vitamin B12 as methylcobalamin – bioactive B12 form, directly used in the methionine and homocysteine cycle.
  • Vitamin B6 – essential cofactor in the trans-sulfuration pathway that converts homocysteine into cysteine.
  • Vitamin B2 – supports MTHFR enzyme function and folate recycling.
  • Anhydrous betaine – methyl donor for the conversion of homocysteine back into methionine.
  • Zinc – cofactor for several enzymes involved in methyl metabolism.

Methylcobalamin vs cyanocobalamin

Many homocysteine supplements have historically used cyanocobalamin, a synthetic form of B12 that the body must first convert into methylcobalamin and adenosylcobalamin. In people with genetic polymorphisms, toxic load or enzyme deficits, this conversion may be inefficient.

  • Methylcobalamin is already active and directly involved in the reaction that converts homocysteine into methionine.
  • Rimetil Homocysteine 400 has used methylcobalamin since its original formulation, not after later reformulations.
  • Many competitors, by contrast, switched to methylcobalamin only after recognising the functional limits of cyanocobalamin.

Who Rimetil Homocysteine 400 is designed for

Rimetil is designed whenever nutritional support for homocysteine metabolism and methylation is required. Its use should always be evaluated with a doctor, especially in sensitive areas such as cardiovascular prevention and pregnancy.

  • People with documented hyperhomocysteinaemia.
  • People with MTHFR polymorphisms and elevated homocysteine levels.
  • Men and women with cardiovascular risk factors where the doctor considers action on homocysteine metabolism appropriate.

Rimetil and pregnancy (always under medical supervision)

Homocysteine metabolism and folate status are particularly important before conception and during pregnancy. In these situations, the use of any supplement targeting homocysteine should always be evaluated and monitored by the gynaecologist or treating doctor.

  • Rimetil provides already active 5-MTHF folate and methylcobalamin, forms often preferred in the presence of MTHFR polymorphisms.
  • In preconception or pregnancy contexts, dose, duration and method of use must be established by the professional following the woman.

Original Dr. Caletti formula

Rimetil Homocysteine 400 comes from Dr. Caletti’s clinical practice. More than thirty years ago, he prescribed this combination of cofactors as a galenic preparation for his patients, with the aim of acting on the methionine-homocysteine cycle in a truly targeted way.

Ketozona has transformed this historical formula into a product-line supplement while maintaining the same approach: vitamins only in active forms, complete cofactors and no unnecessary or potentially undesirable excipients.

MTHFR mutation and increased risk

Some MTHFR enzyme polymorphisms reduce the efficiency of folic acid conversion into 5-MTHF, with a possible increase in homocysteine and a greater need for already active forms of folate and B12. In these cases, a doctor may evaluate supplementation with active nutrients and appropriate cofactors.

Rimetil Homocysteine 400 was created precisely with this logic: supporting the remethylation pathway of homocysteine with 5-MTHF, methylcobalamin, betaine and the cofactors B2, B6 and zinc, in a single capsule.

Risk related to MTHFR mutations and homocysteine

Comparison with competing products

Many “homocysteine” supplements are limited to a mix of folic acid, B6 and generic B12, often cyanocobalamin, with dosages that are not always optimised and without distinguishing between active and non-active forms. Others progressively replaced cyanocobalamin with methylcobalamin only later.

Rimetil Homocysteine 400 has used 5-MTHF and methylcobalamin from the beginning, in synergy with betaine, B2, B6 and zinc, at the maximum permitted dosage, within an original Dr. Caletti formula designed to be complete and biochemically coherent.

Frequently asked questions about Rimetil Homocysteine 400

Some quick answers to better understand the specificity of Dr. Caletti’s original formula and the difference compared with standard homocysteine products.

Methylcobalamin is the already active form of vitamin B12 used in the methionine and homocysteine cycle. Cyanocobalamin must first be converted, and this conversion may be less efficient in some individuals. Rimetil has used methylcobalamin since its origin, avoiding the functional limitations linked to cyanocobalamin.
Because it contains 5-MTHF and methylcobalamin, Rimetil was designed also for people with MTHFR polymorphisms and hyperhomocysteinaemia. In any case, suitability and dosage must be established with your doctor, especially before conception, during pregnancy or in the presence of cardiovascular conditions.
