What is in Essential B Complex?
Each row as the label prints it, per serving of 1 ml. The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).
| Ingredient | Amount | % DV | Among products listing it |
|---|---|---|---|
| Vitamin B2as Riboflavin, Riboflavin 5-Phosphate | 1.45 mg | 110% | 80% of 9,824 products listing riboflavin give more (median 4 mg). |

| Potassiumas Potassium Pidolate | 3 mg | 1% | This amount is far outside what other labels list for potassium, or disagrees with the label's own %DV: possibly a unit or transcription slip in the database. Check the label image on DSLD. |

Is that a lot?
The rows in the top or bottom tenth of the products that list the same ingredient, and any above the adult upper limit at the most servings a day the directions give:
- 96% of the 12,413 products that print an amount of niacin list more than its 2.1 mg of vitamin B3 (filed by NIH under niacin) (median 20 mg).
- Its 1,500 mcg of vitamin B12 is higher than 95% of the 14,425 vitamin B12 products that print an amount; 641 list more.
The NIH database records one serving a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.
The Tolerable Upper Intake Level is the most of a nutrient per day, from food, water and supplements together, that is likely to pose no risk for almost all adults (Institute of Medicine, 2011). It does not apply under medical supervision. This page compares labels; it is not medical advice.
