Eight B vitamins that work as a team, so why buy them one bottle at a time?
Optiolex Vitamin B-Complex covers all eight in a single capsule a day, with folate as 5-MTHF and B12 as methylcobalamin: the forms that circulate naturally in your blood.
😴
Six of the eight for tiredness and fatigue
Riboflavin, niacin, pantothenic acid, vitamin B6, folate and vitamin B12 contribute to the reduction of tiredness and fatigue.
⚡
Seven for energy-yielding metabolism
Thiamine, riboflavin, niacin, pantothenic acid, vitamin B6, biotin and vitamin B12 contribute to normal energy-yielding metabolism.
💊
B2, B3 and B6 in two forms each
Riboflavin alongside riboflavin-5'-phosphate, pyridoxine alongside pyridoxal-5'-phosphate, and nicotinamide alongside inositol hexanicotinate. The phosphate forms already carry the phosphate group your body would otherwise attach itself.

A short, readable ingredients list
A plant cellulose (HPMC) shell and the vitamins themselves. No magnesium stearate, no colours, no preservatives.
B vitamins rarely act alone. Your body uses them as coenzymes, small helpers that keep enzymes working, often along the same metabolic pathways. Combine them from single products and you're left matching forms and doses yourself.
They're also water-soluble, and apart from B12 your body keeps only modest reserves of them. So this formula puts all eight into one capsule a day. Every compound is listed under its chemical name with its own amount, which means you always know exactly which form you're getting and how much of it.
Optiolex is an Austrian brand from Lannach in Styria. Its range is deliberately small and built around the forms that well-informed customers ask for by name.
📋 Recommended use
Take 1 capsule once a day with plenty of liquid.

Why methylcobalamin rather than cyanocobalamin?
Cyanocobalamin is the most common B12 in supplements: stable and inexpensive, but carrying a cyanide group that your body first has to remove. Methylcobalamin carries a methyl group instead and is one of the two coenzyme forms of B12. Vitamin B12 contributes to normal red blood cell formation. It is found in meaningful amounts almost exclusively in animal foods.
⚠️ Important information: Do not exceed the recommended daily dose. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Keep out of reach of young children.
📦 Storage: Store in a dry place at room temperature, protected from light. Protect from heat. Close tightly after use.
💬 Frequently asked questions
-
Why a complex instead of B12 on its own?+
B12 shares several pathways with its neighbours. Vitamin B6, folate and vitamin B12, for example, contribute to normal homocysteine metabolism. A complex gives you all eight in one go, with no need to combine separate products.
-
My urine turns bright yellow. Is that normal?+
Yes. Riboflavin (vitamin B2) is a naturally yellow compound, and each capsule provides 15 mg in two forms. Whatever your body doesn't use right away leaves through the kidneys. The colour is harmless and typical of B-complex products.
-
What do percentages above 1,000% actually mean?+
NRVs are legal reference values for labelling, based on the daily needs of healthy adults. The percentage simply shows how much one capsule provides compared with that reference. Stick to one capsule a day, and if you take other supplements containing B vitamins, add the amounts together.
-
Can I take it alongside Optiolex Omega-3?+
The two don't overlap. The omega-3 capsules provide EPA and DHA from fish oil, while this complex provides B vitamins only. Follow the recommended use on each product.
-
60 or 180 capsules?+
Same formula, different supply. 60 capsules last two months, which is handy for trying it out. If it's becoming part of your daily routine, the
180-capsule pack lasts six months and works out cheaper per day.
