What is High-Absorption Protein?
The quality and quantity of protein are both essential for muscle and bone development. High-absorption protein, as branded by Oikos, refers to protein that is easily absorbed and readily utilized by the body, effectively supporting muscle synthesis. The protein used in Oikos drinks has an absorption rate comparable to boiled chicken breast, indicating a high efficiency in nutrient absorption.
Oikos continues to encourage a healthier lifestyle by offering appealing protein options for various occasions, including their protein yogurt series containing over 10g of protein and low glycemic index characteristics, making it suitable for breakfast, snacks, and late-night cravings. The recent introduction of the Oikos PRO Protein Drink with 18g of high-absorption protein has made protein intake easier for those on the go or after workouts.
Now, with the Oikos PRO series featuring 25g of high-absorption protein, Danone Japan is set to cater to individuals seeking advanced protein intake options, responding to the diverse needs of its consumers.
