“Do not exceed the recommended daily dose. Food supplements should not replace a varied and balanced diet and a healthy lifestyle. If you are pregnant, breastfeeding, under 18 or taking any medication, consult a doctor before use. Stop use if adverse reactions occur.
Interactions: Thiamine (B1) may have reduced absorption when taken with diuretics such as furosemide, and certain chemotherapy agents like fluorouracil may increase thiamine requirements. Riboflavin (B2) can be affected by some tricyclic antidepressants, which may reduce its absorption. Niacinamide (B3) may potentiate the effects of blood pressure-lowering medications and statins, and high doses may enhance the effects and side effects of antidiabetic drugs. Calcium pantothenate (B5) may increase the effects of cholinesterase inhibitors. Pyridoxal-5-phosphate (B6) may decrease the efficacy of some anti-epileptic medications, such as phenytoin and levodopa (unless combined with carbidopa), and high doses can reduce the effectiveness of altretamine (an anticancer agent). Biotin (B7) can interfere with certain laboratory tests, including thyroid and cardiac assays, potentially leading to misdiagnosis. Folates (B9) may reduce the effectiveness of methotrexate (an immunosuppressant and chemotherapy drug) and anticonvulsant drugs such as phenytoin and phenobarbital, while folate absorption can be reduced by certain antibiotics and barbiturates. Vitamin B12 (Methylcobalamin and Adenosylcobalamin) absorption can be reduced by metformin (used for diabetes) and proton pump inhibitors (such as omeprazole); B12 can also interact with chloramphenicol, potentially reducing blood cell production.

Summary: Vitamin B5 helps the body turn food into energy, make hormones, and maintain healthy skin, hair, and nerves. High doses of pantethine may help lower cholesterol in some people.
Vitamin B6 (Pyridoxine) – Review
Dosage: 10–20 mg daily for deficiency (injection), then 2–5 mg daily (oral) for maintenance
Outcome: Helps prevent and treat vitamin B6 deficiency and related conditions; supports metabolism and nerve function
Summary: Vitamin B6 is essential for over 100 enzymes in the body, mainly helping with metabolism, brain health, and making neurotransmitters. It is safe at usual doses, but very high doses over time can cause nerve problems.
Vitamin B7 (Biotin) – Review
Dosage: 5– 500 mcg micrograms daily for deficiency, pregnancy, or breastfeeding.
Outcome: Biotin supports healthy hair, nails, skin, and energy metabolism.
Summary: Biotin is essential for breaking down food into energy and is important for healthy hair, nails, and nerves. Supplementation only helps if you are deficient; benefits for healthy people are unproven.
Vitamin B9 (Folic Acid) – Review
Dosage: 400 mcg daily for adults (typical); 400–800 mcg daily to prevent neural tube defects in pregnancy; 1–5 mg daily for anaemia or deficiency; up to 15 mg daily in special cases
Outcome: Prevents and treats folate deficiency, neural tube defects, and certain types of anaemia
Summary: Folic acid is essential for DNA production, red blood cell formation, and lowering homocysteine levels. Supplementation is especially important before and during pregnancy to prevent birth defects, and in treating megaloblastic anaemia.

Dietary Vitamin B Complex: Orchestration in Human Nutrition throughout Life with Sex Differences – Review
Dosage: Varies by vitamin, age, sex, and life stage
Outcome: Reviews how B vitamin needs, effects, and risks of deficiency change across life and differ by sex.
Summary: B vitamins are needed at every age for energy, brain, and body health. Needs rise during pregnancy, growth, and ageing. Deficiency at any stage can cause serious health issues, so a balanced diet and, if needed, supplements are important.
B Complex is a blend of eight essential B vitamins in their most bioavailable forms, including both methylated and non-methylated, to provide foundational support for energy, nervous system health and cellular resilience. Methylation needs can vary widely due to genetics, diet and individual sensitivity. B Complex was formulated to support a wide range of individuals including those sensitive to high dose methylated b complexes.
Each B vitamin has a unique role in supporting the body’s natural processes.
By using active forms of B vitamins and balancing methylated and non-methylated folate (B9) and B12, this blend supports energy, mental clarity, and detoxification for a wide range of metabolic needs, while minimising the risk of unwanted side effects.
B vitamins are essential in hundreds of cellular reactions, including energy production, DNA formation and repair, neurochemical balance and detoxification. Modern diets, chronic stress, digestive issues, certain medications and genetic variations such as MTHFR can reduce the availability or utilisation of active B vitamins. Over time, low or imbalanced B vitamin status can impair energy metabolism, slow cellular repair, disrupt nervous system function, and weaken the body’s ability to respond to stress. Because B vitamins are water-soluble and not stored in large amounts, they need to be replenished regularly to maintain optimal cellular and metabolic function.
One of the critical links between B vitamins and healthy ageing is vitamin B3’s role in producing NAD+, a molecule essential for cellular energy production, DNA repair, and the activation of longevity molecules such as sirtuins and PARPs. NAD+ levels naturally decline with age, leading to reduced cellular energy, slower repair processes, and increased vulnerability to stress and damage. Niacinamide (B3) supports NAD+ production,helping maintain these vital processes over time.
