Blood-Level or Deficiency Marker is closer to a research marker, so it should be read separately from a directly felt benefit.
The 44.0 score includes research signals from patient or disease contexts. General supplement evidence is not repeated enough, so the C tier remains conservative.
Representative tier calculated from paper evidence that passed the collection audit.
The representative ingredient tier is calculated from these target-level evidence groups.
This is based on lab markers such as blood levels, deficiency correction, or absorption. Read it separately from directly felt outcomes.
This score reflects the strength of this benefit group. The ingredient tier also considers paper count, repetition, population, and study context.
Potential benefit studied in Women's health. These findings come from a defined study population, so everyday effects may differ.
This score reflects the strength of this benefit group. The ingredient tier also considers paper count, repetition, population, and study context.
This range includes studies in specific patient groups. It is not a general dose or recommendation.
Findings from studies of this ingredient alone are separated from findings involving another supplement or medication.
Side effects reported for the ingredient alone are separated from findings involving another supplement or medication.
Symptoms or adverse events reported in studies of this ingredient without another active ingredient.

New evidence for both prevalence and absolute burden of vitamin A deficiency should be used to reconsider, and possibly revise, the list of priority countries for high-dose vitamin A supplementation such that a country's priority status takes into account both
There is no evidence to support the use of vitamin and antioxidant supplements for prevention of cardiovascular diseases.
Vitamin A supplementation is associated with large reductions in mortality, morbidity, and vision problems in a range of settings, and these results cannot be explained by bias.
The Panel on Dietetic Products, Nutrition and Allergies derived Dietary Reference Values for vitamin A based on a factorial approach and considered that a concentration of 7 20 μg retinol/g liver can be used as a target value for establishing the Average Requi
Five years after the clinical trial ended, the beneficial effects of the AREDS formulation persisted for development of NV AMD but not for CGA, consistent with the original recommendations that persons with intermediate AMD or advanced AMD in one eye should co
This review summarizes the effort to build the evidence base and breed 42 OFSP varieties to address widespread vitamin A deficiency in SSA using an integrated agriculture-nutrition approach and describes how the changing policy environment influenced the proce
