Metabolics is proud to present our best-selling Vitamin B Complex Liquid, a premium formulation designed to deliver high-potency, bioavailable B vitamins in their active coenzyme forms. This advanced liquid B complex is unparalleled in composition and quality, providing nutrients that are readily absorbed and immediately utilised by the body.
Unlike many standard B vitamin supplements, which require multiple metabolic conversion steps, our Vitamin B Complex Liquid provides several B vitamins in their biologically active or readily usable forms.
This may support improved utilisation in individuals with higher nutritional demands, increased stress, or those who have difficulty converting certain nutrients efficiently.
What’s in Our Vitamin B Complex Liquid?
Below is a comprehensive overview of the active B vitamins included in our expertly formulated Vitamin B Complex.
Vitamin B6 – Pyridoxal-5-Phosphate (P-5-P)
Most vitamin B6 supplements use pyridoxine hydrochloride, a synthetic form not found naturally in food. Pyridoxine must be converted in the intestines and liver into Pyridoxal-5-Phosphate (P-5-P) before it becomes biologically active.
Conversion may be impaired in individuals with liver dysfunction, enzyme defects, nutrient insufficiencies, or certain medication use. P-5-P is the only active coenzyme form of vitamin B6, directly involved in over 100 enzymatic reactions, including:
• Neurotransmitter synthesis
• Amino acid metabolism
• Hormone regulation
• Nervous system function
Research shows that P-5-P is preferentially utilised under metabolic stress and, unlike high-dose pyridoxine, has not been associated with sensory neuropathy, even at higher intakes.

Vitamin B2 – Riboflavin-5-Phosphate (R5P)
Vitamin B2 is commonly supplied as riboflavin, which must be converted into its active forms:
• Riboflavin-5-Phosphate (R5P)
• Flavin Adenine Dinucleotide (FAD)
These conversions occur in the mitochondria and depend on healthy mitochondrial and hormonal function. R5P and FAD are essential for:
• Energy metabolism and ATP production
• The electron transport chain
• Fatty acid oxidation
• Neurotransmitter metabolism
• Conversion of vitamin B6 to P-5-P
• Activation of folate and tryptophan metabolism
For individuals with chemical sensitivities, medication use, alcohol intake, or hormonal imbalance, R5P is often better tolerated and more efficiently utilised than riboflavin.

Vitamin B1 – Thiamine
Thiamine plays a vital role in carbohydrate metabolism and cellular energy production. It is also essential for the synthesis of key neurotransmitters, including acetylcholine and GABA, supporting cognitive function and nervous system health.

Vitamin B3 – Niacinamide
Our Vitamin B Complex Liquid uses niacinamide rather than niacin. Niacin may cause flushing, gastrointestinal discomfort, or liver stress, while niacinamide is well tolerated.
Niacinamide is efficiently absorbed and converted into the critical coenzymes NAD and NADP, which are required for:
• Cellular energy production
• DNA repair
• Redox reactions
• Brain and nervous system function
Supplementation with niacinamide is an effective way to increase intracellular NAD levels, particularly important for mitochondrial health and healthy ageing.

Vitamin B5
Vitamin B5 (pantothenic acid) is essential for the synthesis of Coenzyme A, a key molecule in fat metabolism and adrenal hormone production. Only D-pantothenic acid is biologically active.
In liquid formulations, Metabolics uses dexpanthenol, a stable and highly bioavailable precursor that converts efficiently into pantothenic acid in the body. This ensures optimal support for:
• Energy metabolism
• Adrenal function
• Fatty acid synthesis

Vitamin B12 – Methylcobalamin & Adenosylcobalamin
This Vitamin B Complex Liquid contains two active forms of vitamin B12:
• Methylcobalamin – essential for methylation and neurological function
• Adenosylcobalamin – required for mitochondrial energy production in the citric acid cycle
Most supplements use cyanocobalamin, a synthetic form not found in nature and requiring conversion. Metabolics uses only biologically active, naturally occurring forms for superior cellular utilisation.
Vitamin B12 absorption is limited to the ileum, making high-quality, active forms essential.

Folate – Calcium L-Methylfolate (5-MTHF)
Metabolics uses calcium L-methylfolate, a stable form of 5-methyltetrahydrofolate (5-MTHF), which is the biologically active form of folate used by the body.
Unlike folic acid, 5-MTHF does not require reduction by the MTHFR enzyme before it can participate in folate-dependent metabolic processes. This may be relevant for individuals who have reduced efficiency in folate conversion.
5-MTHF directly supports:
• DNA synthesis and repair
• Methylation pathways
• Cardiovascular health
• Nervous system function

Biotin (Vitamin B7)
Biotin supports:
• Nervous system and psychological function
• Macronutrient metabolism
• Healthy hair, skin, and mucous membranes
Biotin occurs in a single, highly bioavailable form and is completely absorbed, making it an effective addition to this formulation.

Choline – Choline Chloride
Choline is included as choline chloride, a soluble and bioavailable form that contributes to:
• Phospholipid synthesis
• Cell membrane integrity
• Acetylcholine production (memory and cognitive function)
• Methyl group donation for detoxification and liver health
