Vitamins

The "% of Daily Value": The "Daily Value," or DV, was created by the U.S. Food and Drug Administration for labels on foods and supplements, and implemented in 1994. It is based on two sets of references: Daily Reference Values, or DRVs, and Reference Daily Intakes, or RDIs. DRVs are for nutrients for which no set of standards existed previously, such as fat and cholesterol. RDIs replaced the term "U.S. Recommended Daily Allowances" (RDA).

Serving Size: This indicates how many of the units - tablets, soft-gels, capsules, etc, need to be consumed in a day to reach the percent of daily value listed on the label.

Units of measure reflect the standard reference units for each kind of nutrient. “I.U.,” stands for “International Unit” and is the standard for measuring fat-soluble vitamins. The abbreviation "mg" stands for milligrams, or one-thousandths of a gram, and “mcg" stands for micrograms, or one millionths of a gram.

Double asterisks in place of DV listings mean that DVs have not been established for these nutrients. The nutrients are included in some Weil dietary supplements because studies suggest they have scientifically validated health benefits and are safe to consume at the amounts contained in the supplement.

The "Other ingredients": This is a list of compounds that do not directly contribute to the nutrient DVs in the supplement, but instead aid in functions such as tablet integrity, proper digestion or preservation of shelf life.

The "EXP" indicates the expiration date; that is, the date by which the supplements in the bottle will have degraded to the point that the percent of DV listed on the label is no longer accurate. Consuming supplements that are past their expiration date is usually not harmful, but since the full nutritional value is not received by the consumer, it is recommended that supplements that have passed their expiration date be replaced with fresher ones.

The "LOT" is a number that identifies the specific manufacturing lot that included this particular item. It is useful in the unlikely event that questions arise about the integrity of ingredients or manufacturing processes used to create that lot.
