Naturaltein · Reviewed by COREFITLAB · Published 2026-09-01
Based on a review by COREFITLAB (accessed 2026-09-01).
Based on this review alone: buy it if you care about high protein content (25g per 35g serving, ~72%) — just accept the side seal of the packaging is very sharp and can cause injury when opening.
The reviewer concluded that the Coffee flavor of Naturaltein YES Protein was the superior choice, giving it a 9 out of 10 and describing its taste as akin to cold coffee. Mango scored 8.5/10, and Kesar Badam scored 7/10, while the Chocolate Fantasy taste was not explicitly rated after tasting.
This review unboxes and provides a detailed taste comparison of four Naturaltein YES Protein flavors: Kesar Badam, Chocolate Fantasy, Coffee, and Mango. It also covers the product's nutritional information, inclusion of natural digestive enzymes, and natural sweeteners. The reviewer also performs mixability demonstrations.
Naturaltein YES Protein is a top-tier protein powder due to its high protein percentage and natural ingredients, with the coffee flavor standing out as the best. Each 35g serving delivers 25g of protein and includes natural digestive enzymes like bromelain and papain, aiding digestion. However, the packaging's sharp side seal poses a minor safety concern during opening, as noted by the reviewer's small injury. If you prioritize a high-quality, naturally sweetened protein with excellent digestibility, this product is worth considering. If you are sensitive to sharp packaging edges, exercise caution during unboxing.
