A Placebo-Controlled Study of the Impact of Dietary Salmon Protein Hydrolysate Supplementation in Increasing Ferritin and Hemoglobin Levels in Iron-Deficient Anemic Subjects

Framroze Bomi, Sanjay Vekariya and Swaroop Dhruv

Iron deficiency anemia is the most common micronutrient deficiency in the world today. This placebo-controlled, iron-deficient anemic, patient study measured the changes in serum ferritin concentration, as well as circulatory hemoglobin concentration, after daily supplementation of their normal diet with 16 grams per day of salmon protein hydrolysate tablets. Salmon protein hydrolysate has a low iron content of 3.1 mg/kg versus 20 mg/kg for the whey protein isolate tested here. Yet, our results show that iron-deficient subjects treated with salmon protein hydrolysate for 6 weeks, showed a 14% increase in hemoglobin levels, while treatment with whey protein isolate showed only a 2% increase. Bioactive peptides in the salmon protein hydrolysate may be playing a significant role in increasing iron uptake from a normal diet.
