What does % NRV mean on a vitamin B label?
NRV stands for nutrient reference value, and the percentage shows how much of that reference amount one tablet or one daily dose provides. 100 % means exactly the reference amount, 40 % is less than half of it, 300 % is three times more. In Vissveselibai.lv B vitamīnu komplekss, B5 is 6 mg (100 %) and B12 is 1 µg (40 %).
Percentages exist because each vitamin has its own unit: milligrams, micrograms or niacin equivalents (NE). Percentages compare directly with each other. Milligrams do not compare with micrograms.
Which B vitamins should a B complex contain?
Eight vitamins make the full group, and a label may print the code, the name or both, so B1 and thiamine are the same vitamin.
| Vitamin | Name on the label | NRV per day |
|---|---|---|
| B1 | thiamine | 1.1 mg |
| B2 | riboflavin | 1.4 mg |
| B3 | niacin | 16 mg |
| B5 | pantothenic acid | 6 mg |
| B6 | pyridoxine | 1.4 mg |
| B7 | biotin | 50 µg |
| B9 | folate, folic acid | 200 µg |
| B12 | cobalamin | 2.5 µg |
How do I compare vitamin B complexes?
Read every label in the same five steps and each product turns into one comparable number.
- Write down the % NRV of every vitamin per tablet. A missing vitamin shows up immediately.
- Check how many tablets the label allows per day. Two tablets double the daily percentages. L-metilfolāts prints both: 1 tablet is 400 µg (200 %), 2 tablets are 800 µg (400 %).
- Work out the days per pack: tablets in the pack ÷ tablets per day. Vitamīns B12 has 60 tablets at 1 a day, so 60 days. L-metilfolāts has 60 tablets at 2 a day, so 30 days.
- Work out the price per 30 days: pack price ÷ tablets in the pack × tablets per day × 30. For Vitamīns B12 that is 4.20 ÷ 60 × 1 × 30 = €2.10.
- Compare the forms in the ingredients list. Vissveselibai.lv B vitamīnu komplekss also carries para-aminobenzoic acid (PABA) 31.5 mg, which has no % NRV on the label.
Folic acid or methylfolate, cyanocobalamin or methylcobalamin?
One vitamin can arrive in several forms, and the ingredients list names them differently. At Vissveselibai.lv it looks like this:
- B vitamīnu komplekss: folic acid and cyanocobalamin;
- Vitamīns B12 1000 µg: methylcobalamin;
- L-metilfolāts: calcium L-methylfolate;
- Folijskābe 400 µg: pteroylmonoglutamic acid, the chemical name of folic acid.
The form is a separate point to compare next to the dose. This article does not rank forms and does not favour one over another. Put the dose and the price per 30 days side by side instead.
How much do B vitamins cost per month?
Four B products at Vissveselibai.lv cost €1.43 to €4.20 per 30 days, calculated from the lowest daily dose on the label. The complex covers all eight vitamins for €3.59: B1 1.4 mg, B2 1.6 mg, B3 18 mg NE, B5 6 mg, B6 2 mg, biotin 150 µg, folate 200 µg and B12 1 µg. The other three carry one vitamin each: Folijskābe 400 µg at €1.43, Vitamīns B12 at €2.10, L-metilfolāts at €4.20.
Prices are Vissveselibai.lv selling prices with VAT on 9 November 2026 and can change. The products do not replace each other, because the complex carries eight vitamins and the other three carry one each.
