Aspartame (l-aspartyl-l-phenylalanine methyl ester) known to the public as NutraSweet has been the subject of controversy since it first became an ingredient in food products. The perceived sweetness of aspartame in humans is due to its binding of the heterodimer G-protein coupled receptor formed by the proteins TAS1R2 and TAS1R3. Aspartame was used in experiments on animals to study its role in delays of osteoarthritis. It was shown, that aspartame improved bone cortical density and muscle mass, and might contribute to a better quality of life for these diseased animals. In addition, was investigated the effect in patients with sickle cell anemia. It was revealed, that oral administration of aspartame lead inhibition of sickle cells. That effect was explained by binding aspartame with two human Bence Jones proteins: Mcg and Sea. Thus was suggested, that aspartame could interfere with sickle hemoglobin fibril formation. Then several studies showed that aspartame had no effect on the polymerization of sickle hemoglobin.

Sample Use Guides

23 subjects from the Sickle Cell Clinic (University of Oklahoma Health Sciences Center, Oklahoma City, Okla) consented to participate in a randomized single-dose administration of 1.5, 3.0, or 6 mg/kg aspartame.
Route of Administration: Oral
For the in vitro studies, blood from 20 subjects monitored for sickle cell anemia was collected in heparinized tubes. Specimens were divided in thirds and aspartame was added to 2 tubes to yield a 1 mg/mL or 2 mg/mL concentration. Sickled cells that were present after a drop from each aliquot was added to a fresh 2% metabisulfite solution were counted 3 times. For the in vitro studies, sickled cells decreased from 28% to < 14% when 1 mg/mL aspartame was added and decreased further with 2 mg/mL.
