Ingredient spotlight · Folate in Health Royals’ peak performance formula · 5 min read
Why folate matters throughout life, how folic acid differs from 5-MTHF and where MTHFR fits into the story.
Key takeaways
• Folate contributes to normal blood formation, homocysteine metabolism, psychological function and the reduction of tiredness and fatigue.
• Folate, folic acid and 5-MTHF belong to the same vitamin family, but they are different molecular forms that enter folate metabolism at different points.
• Health Royals provides 200 µg of folate as 5-MTHF, equivalent to 100% NRV, through Quatrefolic®.
Folate has become closely associated with pregnancy.
That association exists for good reason. Folate contributes to maternal tissue growth during pregnancy and is central to preconception nutrition.
But folate biology does not begin with pregnancy, and it does not end there.
Folate also contributes to normal blood formation, normal homocysteine metabolism, normal psychological function and the reduction of tiredness and fatigue. It has a role in the process of cell division.
Folate is not a nutrient for one life stage. Its functions continue throughout life.
Why is folate about more than pregnancy?
Folate belongs to the B-vitamin family and is also known as vitamin B9.
Its role is closely connected with processes that require the creation and renewal of cells. Folate has a role in cell division and contributes to normal blood formation.
It also contributes to normal amino acid synthesis, normal homocysteine metabolism, normal psychological function and the normal function of the immune system.
These functions remain relevant long after the reproductive years. Blood cells continue to be produced, tissues continue to renew and folate-dependent metabolic pathways remain active throughout adulthood.
Pregnancy may be folate’s most familiar chapter, but it is not the whole story.
What is the difference between folate and folic acid?
The word folate describes a family of related vitamin B9 compounds.
Food folates occur naturally in foods including leafy green vegetables, legumes, asparagus, avocado and certain fruits.
Folic acid is a synthetic, oxidised form of vitamin B9 widely used in fortified foods and supplements. It is stable and has played an important role in public-health nutrition.
Before folic acid can participate fully in the body’s folate cycle, it must pass through several conversion steps.
5-MTHF, short for 5-methyltetrahydrofolate, is different. It is the predominant folate form found in human circulation and is already supplied in the reduced folate form used in the methionine cycle.
European assessments recognise 5-MTHF as a bioavailable source of folate. At relevant supplemental intakes, it is treated as at least comparable with folic acid for contributing dietary folate equivalents.
Folate identifies the vitamin family. Folic acid and 5-MTHF identify particular forms within it.
Where does MTHFR fit into the story?
MTHFR stands for methylenetetrahydrofolate reductase. It is an enzyme involved in converting one folate form, 5,10-methylene-THF, into 5-MTHF.
MTHFR has become one of the most discussed genes in nutrition, but its role is often oversimplified.
Common genetic variants can influence enzyme activity to different degrees. This does not mean that everyone with an MTHFR variant is unable to process folic acid, nor does a common variant automatically indicate a medical problem.
The useful distinction is more precise: 5-MTHF does not require the MTHFR conversion step to become 5-MTHF, because it is already supplied in that form.
Human studies have also shown that 5-MTHF can raise circulating folate effectively in people with different MTHFR genotypes.
The point is not to turn a common genetic variant into a diagnosis. It is to understand where different folate forms enter the metabolic pathway.
Why does Health Royals use 5-MTHF?
Health Royals’ peak performance formula provides folate as 5-MTHF through Quatrefolic®.
Quatrefolic® is the glucosamine salt of (6S)-5-methyltetrahydrofolate. In simpler terms, it is a stabilised ingredient designed to provide the 5-MTHF form of folate directly.
The glucosamine salt gives the ingredient a defined molecular identity and formulation profile, including high water solubility and suitability for use in food supplements.
The choice does not rest on claiming that folic acid is ineffective. Folic acid is a well-established source of vitamin B9 and remains important in nutrition and public health.
The distinction is that Quatrefolic® supplies the predominant circulating folate form directly, rather than beginning earlier in the conversion pathway.
The choice is not simply folate rather than no folate. It is which folate form, from which source and for what role in the formula.
Why does the formula provide 200 micrograms?
Health Royals’ peak performance formula provides 200 µg of folate, equivalent to 100% of the Nutrient Reference Value.
The amount is deliberately nutritional rather than therapeutic. It provides the full adult NRV through a defined 5-MTHF ingredient.
Human research has shown that 5-MTHF can improve folate status and support normal homocysteine metabolism at nutritional doses.
In one randomised study, approximately 200 µg of 5-MTHF was effective, while doubling the amount did not produce an additional homocysteine benefit.
This does not establish one universally optimal amount for every person. It does support a wider formulation principle: more is not automatically more meaningful.
The purpose is not to create a high-dose folate product. It is to provide a clear daily contribution in a defined form that makes sense within the complete formula.
Two hundred micrograms is a purposeful daily amount: the full adult NRV, provided in a bioavailable 5-MTHF form without inflating the dose for label impact.

How folate fits into the complete formula
Folate is not included in isolation.
In Health Royals’ peak performance formula, Quatrefolic® sits alongside methylcobalamin, thiamine, vitamin D3, vitamin K2, algal omega-3, olive polyphenols, zinc and selenium.
Folate and vitamin B12 are separate nutrients, but their roles intersect. Both contribute to normal homocysteine metabolism and have a role in the process of cell division.
Folate contributes to normal blood formation, while vitamin B12 contributes to normal red blood cell formation. Their functions are related, but one does not replace the other.
Folate and vitamin B12 are also important to consider together because high folate intakes can complicate the recognition of vitamin B12 deficiency. Health Royals therefore combines a measured 5-MTHF amount with methylcobalamin rather than building the folate story around a high folic-acid dose alone.
Folate also contributes to the reduction of tiredness and fatigue, normal psychological function and normal immune function, placing it naturally within a formula designed around energy, resilience and everyday nutritional support.
The aim is not simply to include folate. It is to select its form and amount with the same precision applied to the complete formula.
Important: Folate needs differ during pregnancy and when planning a pregnancy. People who are pregnant or trying to conceive should follow national guidance, which may recommend a specific folic-acid amount in addition to dietary folate. Anyone taking medication, managing a medical condition or concerned about folate or vitamin B12 status should consult a qualified healthcare professional.
