Vitamin-B12 Supplements

Overview Label Accuracy Score Non-Toxicity Score Nutritional Profile Score

Overview

For every Vitamin-B12 Supplement, the following parameters are tested across multiple labs:

Vitamin-B12 content (mcg per capsule)

Heavy Metals - Lead, Arsenic, Cadmium, Mercury (ppm - parts per million)

Since every parameter gets tested at multiple labs, Unbox Health arrives at a consensus value for each parameter based on our internal consensus rules.

Finally, the consensus values are used to derive a product’s Label Accuracy Score and Non-Toxicity Score. From these, the product’s Aggregate score and Rating are calculated.

Label Accuracy Score

Label Accuracy Score is defined here.

For Vitamin-B12 Supplements, an Accuracy value is calculated for these parameters: Vitamin-B12. Once these Accuracy values are computed, the Label Accuracy Score is calculated using this formula:

👉

Label Accuracy Score = Vitamin-B12 Accuracy

The Accuracy value for a parameter is calculated by comparing the lab test result vs the label claim using the scale shown below. The scale is defined as per FSSAI guidelines, while allowing for a standardised margin of uncertainty in lab testing.

Parameter Accuracy	Range	Notes
Vitamin-B12 Accuracy	0.00 - 1.00	Only used if Vitamin-B12 value is explicitly claimed on product label.

Note: For Vitamin-B12 Supplements, if a parameter’s lab result falls between ±0.17mcg of the label claim (per capsule), the accuracy value for that parameter is assumed to be 1.00.

Non-Toxicity Score

Non-Toxicity Score is defined here.

For Vitamin-B12 Supplements, a Non-Toxicity value is calculated for these parameters: Lead, Arsenic, Cadmium, Mercury. Once these Non-Toxicity values are computed, the Non-Toxicity Score is calculated using this formula:

👉

Non-Toxicity Score = Lead Non-Toxicity x Arsenic Non-Toxicity x Cadmium Non-Toxicity x Mercury Non-Toxicity

The Non-Toxicity value for a parameter is calculated by comparing the lab test result vs the FSSAI limits for that parameter using the scale shown below. The scale is defined as per FSSAI guidelines.

Non-Toxicity Values	Range	Notes
Lead Non-Toxicity	0.00 - 1.00	Calculated based on FSSAI guidelines for Lead levels
Arsenic Non-Toxicity	0.00 - 1.00	Calculated based on FSSAI guidelines for Arsenic levels
Cadmium Non-Toxicity	0.00 - 1.00	Calculated based on FSSAI guidelines for Cadmium levels
Mercury Non-Toxicity	0.00 - 1.00	Calculated based on FSSAI guidelines for Mercury levels
