How does B-Complex 50 mg compare?
Ingredients listed on each label, against the vitamin category average of 6.8. Data from the NIH DSLD.
B-Complex 50 mg lists 18 ingredients more than 100% Natural E Liquid. That is 13 above the vitamin average.
What the Label Data Shows
With 20 ingredients on the label, B-Complex 50 mg is one of the more extensive vitamin supplement formulas from GNC in the NIH Dietary Supplement Label Database (DSLD), sold in capsule form. These ingredients span 6 nutrient categories, vitamin, non-nutrient/non-botanical, botanical, protein, and 2 more, reflecting a multi-component formula rather than a single-nutrient product.
Across a broader 20-ingredient formula, 20 of 20 sit outside the FDA's reference-intake system entirely -- common at this scale, since multi-ingredient blends tend to accumulate botanicals, amino acids, and specialty compounds the FDA has never benchmarked. That's expected breadth, not a red flag on its own.
Availability status shapes how this label record is best used. This product is currently listed as off-market in the DSLD, with its label first entered into the database on 2013-09-25. An off-market listing means production and distribution under this label have stopped, but the DSLD does not delete the entry, it stays on file for historical reference and formulation-history tracking.
About the DSLD database
The DSLD is a label database, not an FDA approval list, under the 1994 DSHEA framework, dietary supplements do not require pre-market approval, and label information reflects what manufacturers self-declare rather than independent laboratory verification. This page presents factual label data for reference only and is not medical advice; consult a licensed healthcare provider before making decisions about any supplement.
