Prescription methylfolate vs. over the counter

Medical foods have distinct differences from dietary supplements and conventional foods. They are designed as therapeutic interventions for specific medical conditions, while OTC (over-the-counter) supplements are intended to improve or maintain nutritional status.


Dietary supplements vs. medical food
The FDA defines medical foods as “intended for the specific dietary management of a disease or condition for which distinctive nutritional requirements, based on recognized scientific principles, are established by medical evaluation.”


Medical foods are designed to meet distinct nutritional needs that cannot be met by standard diet alone due to a specific disease or medical condition. These conditions may include impaired digestion, absorption, metabolism or special nutrient requirements that require clinical diagnosis and physician oversight.1


A dietary supplement, on the other hand, is a product intended for ingestion that contains ingredients intended to supplement the diet, such as vitamins and minerals (common supplements include vitamin D, vitamin E, calcium, vitamin C, B vitamins, magnesium, selenium and zinc), herbs and other botanicals and/or amino acids.2

Differences in OTC products vs. prescription products

Regulations

Medical foods are regulated under FDA guidance but are not classified as drugs and do not require a prescription.

OTC dietary supplements are not subject to FDA pre-market approval, which means manufacturers can sell products without submitting evidence of safety or efficacy. The FDA will step in if safety issues arise.

Medical supervision requirements

Physician supervision is required for medical foods, but a prescription is not legally required under FDA regulations.

OTC supplements can be purchased by the user and taken according to directions on the product label.

Manufacturing standards

Medical foods must follow Good Manufacturing Practices (GMPs) similar to pharmaceuticals, with stringent quality control, batch testing and documentation requirements. 

OTC supplements follow less rigorous dietary supplement GMPs, which can result in variable product quality.

Clinical substantiation

Medical foods require scientific evidence demonstrating they address the distinctive nutritional needs of the target medical condition. This includes published peer-reviewed research supporting their formulation. 

OTC supplements generally require evidence to back up claims, but this is not strictly regulated.

Formulation

Medical foods contain specific nutrient combinations and dosages based on the metabolic requirements of particular diseases or conditions. 

OTC products are formulated by the brand and often use general population recommendations.

Cost structure

Medical foods typically cost significantly more ($50-300+ monthly) because their development involves extensive research, clinical validation, and specialised manufacturing.

OTC supplements vary widely in price, depending on ingredient quality, manufacturing standards and product development.

Purity and contamination controls

Medical foods undergo more extensive testing for heavy metals, microorganisms and other contaminants. 

OTC supplements may have inconsistent testing protocols across manufacturers, leading to potential quality which can result in variations between brands and batches.

Labeling requirements

Medical foods must include specific labeling about their intended medical use and supervision requirements. OTC supplements cannot make disease claims and are limited to structure/function statements.

Insurance coverage

Some medical foods may qualify for insurance reimbursement when prescribed for covered conditions. OTC supplements are typically not covered by insurance plans.

Prescription medical foods

  • All ingredients in medical foods must be GRAS (Generally Recognized As Safe) for their intended use under FDA food regulations.
  • People using medical foods must be under ongoing medical supervision during use.
  • Medical foods can make disease-related claims, such as for diabetes, obesity or heart disease.
  • May be powders, liquids or tablets.

Dietary supplements

  • A product that contains a ‘dietary ingredient’, including vitamins, minerals, amino acids and herbs or botanicals.
  • May also contain other dietary substances such as that are part of the food supply, such as enzymes, probiotics, concentrates, metabolites, constituents and extracts.
  • Available in many forms, including tablets,capsules, softgels, liquids and powders. 
  • Designed to support good health and maintain or improve nutritional status. 
  • Cannot claim to diagnose,treat, prevent or cure specific diseases or health conditions but can make claims regarding their effect on the body's structure or function or about the nutrient content of the product.


Why would doctors not prescribe it when you have MTHFR (or another mutation)? Should you refer to an OTC product?
Medical foods do not require a prescription, although a clinician may still choose to write one. Prescriptions are only required for drug products. Your doctor may not recommend Deplin® if your folate levels are already healthy, even if you have a MTHFR genetic mutation.

Frequently Asked Questions about prescription and OTC methylfolate

Do you need a prescription for L-methylfolate?

No, you can purchase L-methylfolate supplements over the counter. If you have a folate deficiency, your doctor may recommend a medical food such as Deplin®.

Is prescription L-methylfolate the same as over-the-counter?

No. Over-the-counter L-methylfolate products vary widely in terms of formulation, potency and ingredients. However, some brands such as Methyl-Life® have the same formulation and ingredients as the medical foods methylfolate, Deplin®.

How do I know if I need L-methylfolate?

You may need methylfolate if you a) are clinically tested as having a folate deficiency or low folate levels or b) you have an MTHFR genetic mutation, which means that standard folic acid is not suitable.

What is the best form of methylfolate to take?

Some research indicates that the calcium salt form is the best form of methylfolate. This is the form used in medical foods such as Deplin®, and by leading supplement brands such as Methyl-Life®.
Methyl-Life® uses a patented calcium salt methylfolate called Cerebrofolate® that has been tested as the purest and the most chemically stable form of methylfolate available on the market. It is quickly absorbed by the body as it is the predominant form used in biological processes.
