Energy metabolism, nervous system support, methylation support
Adults with busy schedules seeking convenient daily B-vitamin intake or those with low intake of B-rich foods.
Take 1 tablet once daily, preferably with a meal; B vitamins are often better tolerated with food, and sustained release tablets should be swallowed whole.

Pantothenic acid forms part of coenzyme A, which is central to converting carbohydrates, fats, and proteins into usable cellular energy.
Caution: High amounts may cause mild digestive discomfort in some people; take with food if sensitive.
Methylcobalamin supports one‑carbon metabolism and red blood cell formation, and helps convert food into cellular energy.
Caution: Very high B12 intakes are generally well tolerated but can affect certain lab tests; separate timing from lab draws if advised.
Pyridoxal-5-phosphate acts as a coenzyme in amino acid metabolism and neurotransmitter synthesis.
Caution: Long-term high intakes of B6 may cause tingling or numbness; stay within suggested use unless advised otherwise.
5‑MTHF is the bioactive form of folate that donates methyl groups for homocysteine metabolism and DNA synthesis.
Caution: Folate may mask low vitamin B12 status on some blood tests; consistent B12 intake is important.
Benfotiamine supports carbohydrate metabolism by helping enzymes convert glucose into energy within cells.
Caution: May cause mild stomach upset in some individuals; take with food if needed.
Activated, coenzyme forms of B vitamins supply directly usable cofactors for energy metabolism and neurotransmitter pathways. 5‑MTHF and methylcobalamin support methylation, while P5P and benfotiamine aid carbohydrate and amino acid processing; pantothenic acid anchors coenzyme A for broader macronutrient utilisation.

As a nutritional supplement, take 1 tablet daily. Or use as directed by your healthcare professional
