Q3: What is whey isolate protein or whey protein isolate (WPI)?
Whey protein powder is derived from cow’s milk. There are three types of whey protein products: whey protein concentrate (WPC), whey protein isolate (WPI), and whey protein hydrolysate (WPH).
Whey protein isolate (WPI) is processed to reduce whey’s fat and lactose content, leaving mainly protein. Whey isolate protein has the best quality of protein.
Health&Tea uses WPI in our Isolate Protein Matcha products.
Q4: What are benefits of whey protein isolate (WPI)?
WPI contains a high level of protein (above 90% of protein content) and has very low fat, cholesterol, and lactose. Several studies on PubMed.gov suggest that Whey isolate protein is good for muscle growth when taken over time with regular resistance training (reference 1, 2, 3). According to an article “Difference between Whey and Whey Isolate” on Webmd, whey protein isolate may be better for people who have trouble digesting lactose or are lactose intolerant.
Q6: Are there any health tips when using Health&Tea Isolate Protein Matcha Powder?
You still need to do exercise or workout to build muscles when using Health&Tea Isolate Protein Matcha products.
The best time to drink Health&Tea Isolate Protein Matcha products is within 30 minutes after workout.
Whey protein isolate (WPI) may be a suitable choice for people who are lactose intolerant.
