B-complex

Buy B-complex: all B vitamins in one supplement

A B-complex is a supplement that combines the eight B vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6, B8 (biotin), B11 (folic acid or folate) and B12. B vitamins are water-soluble and occur naturally in products such as whole grains, legumes, eggs, dairy, meat and green vegetables.

In this collection you will find various formulas: active B complexes with methyl forms such as methylcobalamin and methylfolate, vegan variants, low and high doses, and combinations with extra B12 or folic acid. This way you can choose the composition and dosage that suits your preference.

What are B vitamins?

The B vitamins are a group of eight individual vitamins that are often referred to together because they occur in the same foods. Each B vitamin has its own function in the body. Because they are water-soluble, the body stores them only to a limited extent and regular intake through food is important.

Permitted health claims for B vitamins

Several health claims are permitted for the individual B vitamins. Vitamin B1, B2, B3, B6, B12 and biotin contribute to normal energy-yielding metabolism and to the normal functioning of the nervous system. Vitamin B2, B3, B5, B6, B12 and folic acid contribute to the reduction of tiredness and fatigue. Vitamin B6 and B12 contribute to normal psychological function. These claims apply to products that are a source of the vitamin in question.

Active forms: methylcobalamin and methylfolate

Some B complexes contain so-called active or methylated forms, such as methylcobalamin (B12), methylfolate (5-MTHF) and pyridoxal-5-phosphate (B6). Other formulas use the classic forms such as cyanocobalamin and folic acid. The label states which form has been used for each vitamin.

Dosage and reference intake

The amount per B vitamin varies greatly by product. The label states the amount and percentage of the reference intake (RI) for each vitamin. Stick to the recommended daily amount on the packaging and do not unknowingly combine multiple products containing the same vitamins.

Capsules, tablets or drops?

B complexes are available as capsules, tablets and sometimes in a liquid form. Capsules and tablets are easy to dose and convenient to take with you. A bright yellow color of the urine after intake is normal and is caused by vitamin B2 (riboflavin).

Who is it for?

A B complex is intended for adults who want to supplement their diet with the B vitamins in one product. People also often choose a B complex or separate B12 when following a plant-based diet. If you are pregnant, breastfeeding or taking medication, consult your doctor or pharmacist beforehand. A dietary supplement is not a substitute for a varied diet and a healthy lifestyle.

What to look for when buying?

Compare the form of the vitamins (active or classic), the amount per vitamin and the percentage of the RI, the number of tablets or capsules per package and whether the product is vegan. Also view our collections Vitamin B12 and Folic Acid.
