B50, B100 and 100% NRV: what the strength names do not tell you
Share
B50, B100 and 100% NRV do not mean the same thing. B50 and B100 appear in product names. An NRV percentage is a labelling reference for a particular nutrient. None should be read as a single strength score for the whole formula.
The useful comparison is the amount of each vitamin in the complete daily serving, with its unit attached. A larger number in a product name does not mean every ingredient has that number of milligrams.
Actual labels show the exceptions
The examples below were checked on 7 November 2026. Solgar's manufacturer pages identify a one-capsule daily serving for its B-Complex 50 and B-Complex 100. The individual amounts below are from the corresponding Holland & Barrett B50 panel and B100 panel.
Hyoomen's quantities come from the displayed PANMOL B-complex back label, per daily dose of two capsules.
| Nutrient | Named Solgar B50 example | Named Solgar B100 example | Hyoomen PANMOL B Complex |
|---|---|---|---|
| B1 | 50 mg | 100 mg | 1.1 mg |
| B6 | 50 mg | 100 mg | 1.4 mg |
| B12 | 50 micrograms | 100 micrograms | 2.5 micrograms |
| Biotin | 50 micrograms | 100 micrograms | 50 micrograms |
| Folic acid or B9 declaration | Folic acid 400 micrograms | Folic acid 400 micrograms | B9 200 micrograms; exact form not identified |
The B50 example does not provide 50 mg B12. It provides 50 micrograms. The two named Solgar examples also declare the same folic acid amount despite their different product numbers.
These are specific formulas, not definitions for every product sold as B50 or B100. Check the current pack and exact variant rather than applying this table to another brand.
Keep amounts and percentages separate
One milligram is 1,000 micrograms. Keeping those units visible prevents a thousand-fold reading error. Adding all the numbers into a total would also be unhelpful: the vitamins are different nutrients, not interchangeable portions of one substance.
Hyoomen's displayed back label gives 100% NRV beside each of its eight B vitamins. That does not mean 100 mg of each vitamin. For example, the B6 declaration is 1.4 mg while B12 is 2.5 micrograms.
NRV means nutrient reference value. It does not diagnose what you need, establish a treatment dose or measure how much you absorb. Likewise, 100% is not a safety score or a guarantee that a formula suits everyone.
Check B6 before choosing a higher-number formula
The B6 amounts in the two named Solgar examples are materially different from the Hyoomen declaration. This deserves attention rather than being treated as an automatic upgrade.
The NHS B-vitamin guidance advises not to take more than 10 mg B6 a day in supplements unless advised by a doctor. Both named Solgar panels also carry a long-term B6 caution.
The NHS advice is not a promise that any amount below 10 mg is suitable for every person, nor a recommendation to use that amount. Check other supplements for repeated B6 and take professional advice about an existing routine rather than treating a product name as permission to take more.
Compare the formula you mean to buy
Separate the product name, daily serving, vitamin amounts and ingredient forms. Hyoomen's quinoa-sprout source does not identify its exact B-vitamin chemical forms, and no methylated-form claim is made here. A source preference and a quantity comparison are separate decisions.
If you want to consider a B complex whose displayed panel declares all eight vitamins at 100% NRV, review Hyoomen B Yourself's product information and two-capsule directions. The supplement-label guide covers the wider serving and ingredient checks.
