Show Niacin (B3) as Niacin Equivalent
Both the DRI and DRV describe amounts needed as niacin equivalents (NE), calculated as 1 mg NE = 1 mg niacin or 60 mg of the essential amino acid tryptophan. This is because the amino acid is utilized to synthesize the vitamin.
It would be nice to have the choice to display B3 in NE units, i.e. automatically adding the NE from Tryptophan.
