LABDOOR.COM is an independent startup that tests supplements and gives scores based on :
1.LABEL ACCURACY - analyzes the actual quantities of active ingredients and key nutrients in a product, these values are compared to their manufacturer's claims on product packaging and Nutrition Facts labels.
KEY TERM: Mean Absolute Deviation (MAD). Simply stated, this is the average difference between actual and claimed data in a category. Products that are recorded to be closer to their label claims than this value receive higher Label Accuracy scores, and vice versa.
2.PRODUCT PURITY - tests dietary supplements for contaminants like lead, cadmium, arsenic, mercury, and benzene. Products exceeding the Upper Limit (UL) for supplement toxicity receive the lowest scores, and Product Purity ratings are scaled upwards until products receive ND (non-detection) values.
KEY TERM: Minimal Risk Level (MRL). MRLs are a CDC estimate of the daily human exposure to a hazardous substance that is likely to not cause long-term health effects. This quantity, combined with the FDA action level for specific hazardous food contaminants, sets the Upper Limit for supplement toxicity.
3.NUTRITIONAL VALUE - analyzes the actual values of key nutrients, such as calories, fat, carbohydrates, and protein, and also the positive effects of added vitamins and nutrients. This generates a nutrition score that approximates the relative effect of one serving of a specific product on your overall diet.
KEY TERM: Glycemic Load (GL). Many experienced dieters have heard of the Glycemic Index (GI), which measures the effect of an ingredient or product on increases in blood sugar.
4.INGREDIENT SAFETY - seek to quantify the answers to four key questions: What are the ingredients of concern in these products? How much is too much? What negative health effects could be caused by these amounts? How significant are these health risks? Products that minimize these risks rank highly for overall ingredient safety.
KEY TERM: Upper Limit (UL): UL defines the highest average ingredient consumption expected to pose no adverse health effects. The Institute of Medicine sets Tolerable Upper Intake Levels (UL) for key nutrients, vitamins, and minerals. The FDA and CDC set Minimal Risk Levels for many inactive ingredients and contaminants. When no established UL exists for an ingredient, Labdoor curates the best peer-reviewed clinical studies in order to create our own UL values.
5.PROJECTED EFFICACY - seek to project the answers to three key questions: How much should I take? What benefits will it provide? How significant are these benefits? Products that satisfy these three questions rank highly for projected efficacy in their indicated uses.
KEY TERM: Daily Reference Intake (DRI): The U.S. Institute of Medicine (IOM) set DRI values in 1997 as nutrition standards to signify adequate or recommended consumption. The DRI standards were created to replace the World War II-era Recommended Daily Allowance (RDA), which are still used to generate % Daily Value (%DV) values in U.S. Nutrition Facts statements.
Hope this will answer and help anyone who seeks to buy any of the rated supplemnts.
