In the US, comsumption of added 5´-ribonucleotides averages 4 mg per day, compared to 2 g per day of naturally occurring purines. A review of literature by an FDA committee found no evidence of carcinogenicity, teratogenicity, or adverse effects on reproduction.As it is a fairly expensive additive, it usually is not used independently of glutamic acid; if disodium inosinate is present in a list of ingredients but MSG does not appear to be, it is possible that glutamic acid is provided as part of another ingredient or is naturally occurring in another ingredient like tomatoes, Parmesan cheese or yeast extract. It is often added to foods in conjunction with disodium guanylate; the combination is known as disodium 5´-ribonucleotides.
