a

The total Vitamin A estimate takes into account both preformed retinol and assumed additional retinol formed in the metabolism of alpha-, beta-carotene, and cryptoxanthin.

b

Recommended levels are ⅔ of the RDA level for adults over 50 years of age for micronutrients for which no DRI has been set.

c

Vitamin K is not typically included in multivitamin and/or mineral supplements, nor did any of the participants report taking supplements enriched with phylloquinones or menaquinones.
