Description

All 8 essential B vitamins – including bioactive coenzyme forms, in a single daily capsule

Getting all eight B vitamins in their active coenzyme forms usually means a handful of separate supplements. The Optiolex B-Complex XVII brings them together in one capsule – including Riboflavin-5-Phosphate, Pyridoxal-5-Phosphate, methylcobalamin and (6S)-5-MTHF, the directly usable form of folate that requires no conversion by the MTHFR enzyme.

One capsule per day covers a 6-month supply, combining both the standard precursor forms and their ready-to-use coenzyme counterparts – all clearly declared as separate compounds.

⚡ Energy metabolism B1, B2, B3, B5, B6, B7, B9 & B12 contribute to normal energy-yielding metabolism

🧠 Nervous system B1, B2, B6, B7 & B12 contribute to the normal function of the nervous system

🧬 Psychological function B6, folate (B9) & B12 contribute to normal psychological function

🩸 Blood formation Folate (B9) & vitamin B12 contribute to normal blood formation

💪 Reduces tiredness B2, B3, B5, B6, B9 & B12 contribute to the reduction of tiredness and fatigue

🔬 Bioactive forms Contains R5P, P5P, 5-MTHF & methylcobalamin – ready-to-use coenzyme variants

B vitamins are water-soluble micronutrients that act as co-enzymes in some of the body's most fundamental metabolic processes – carbohydrate, fat, protein and nerve metabolism. Because they are water-soluble, the body does not store them; they need to be replenished regularly through food or supplementation.

The Optiolex B-Complex XVII pairs each classic vitamin form (such as thiamine hydrochloride and pyridoxine hydrochloride) with its corresponding active coenzyme variant in a single formula. Riboflavin-5-Phosphate (R5P) is the active coenzyme form of vitamin B2; Pyridoxal-5-Phosphate (P5P) is the active coenzyme form of vitamin B6. The formula also includes (6S)-5-methyltetrahydrofolic acid (5-MTHF) as a glucosamine salt – the metabolically ready form of folate that does not require prior conversion by the MTHFR enzyme. Methylcobalamin is the bioactive, methylated form of vitamin B12.

Recommended intake

1 capsule daily with plenty of water.
Pack size: 180 capsules (6-month supply).
Each serving contains, among others: 100 mg vitamin B1 · 15 mg vitamin B6 + 8 mg P5P · 400 mcg methylcobalamin · 400 mcg 5-MTHF · 400 mcg biotin.

💡 Tip: Take in the morning with breakfast to reduce the chance of stomach sensitivity on an empty stomach.

Quality & Origin

What are bioactive B vitamins and how do they differ from standard forms?

Many B vitamins are found in food – and in conventional supplements – as precursor forms that the body first needs to convert into their active coenzyme variants through enzymatic steps. For example, the body converts riboflavin into Riboflavin-5-Phosphate (R5P) using the enzyme flavokinase. The Optiolex B-Complex XVII contains both the standard precursor form and the finished coenzyme variant side by side, each declared as a separate compound.

What is inositol and why is it included in this B-complex?

Inositol – included here as inositol hexanicotinate, a compound of niacin and inositol – is a cyclic alcohol structurally related to the B vitamin family, historically referred to as "vitamin B8". It is a component of cell membranes and is involved in intracellular signal transduction. Inositol hexanicotinate is considered a more stomach-friendly niacin form, as it releases niacin more gradually than free nicotinamide.

Notices & storage

Food supplements are not a substitute for a balanced diet and the recommended daily dose should not be exceeded. A varied and balanced diet and a healthy lifestyle are important. Store in a cool, dry place, away from light and out of the reach of young children. Protect from heat. Reseal tightly after use.

During pregnancy and breastfeeding: the formula contains 400 mcg 5-MTHF (active folate) per daily serving – consistent with standard folate supplementation recommendations in pregnancy. Individual medical advice is recommended.

The Optiolex B-Complex XVII combines classic precursor forms (e.g. riboflavin, pyridoxine) with their corresponding active coenzyme variants (Riboflavin-5-Phosphate, Pyridoxal-5-Phosphate). Both forms are included as separate compounds and are declared individually on the label.
Standard folic acid (pteroylmonoglutamic acid) must first be converted in the body into its active form (5-methyltetrahydrofolic acid, 5-MTHF) by the enzyme MTHFR. This formula supplies (6S)-5-MTHF directly as a glucosamine salt – the metabolically ready form that requires no prior enzymatic conversion. Folate contributes to normal blood formation and normal psychological function.
B vitamins are obtained through food, but intake can be lower during certain life stages or when following a restricted diet – for example in those who avoid animal products, or during periods of increased demand such as stress or physical training. For individual supplementation advice, please consult a healthcare professional.
Yes. The capsule shell is made from hydroxypropyl methylcellulose (HPMC) – a plant-derived material containing no animal-derived ingredients, suitable for vegan and vegetarian lifestyles.
Combining this product with other supplements is generally possible, but the total daily intake of each B vitamin should be taken into account. If you are taking blood-thinning medication (e.g. warfarin, aspirin, heparin), please consult your doctor or pharmacist before use.

This product complies with the requirements of the EU General Product Safety Regulation (GPSR, Regulation (EU) 2023/988).
