The real difference-maker is whey protein’s leucine content. Leucine is a branched-chain amino acid (BCAA), and research shows it’s the single most important amino acid for supporting muscle growth. The International Society of Sports Nutrition (ISSN) suggests for individuals looking to maximize muscle gains should eat protein in doses of 20 to 40 grams per meal with three to four meals throughout the day. Each meal should contain 0.7 to 3 grams of leucine, which whey protein hits those targets perfectly.
Your average 3 ounce serving of beef, poultry, and pork will provide you with 2 to 2.6 grams of leucine, with seafood not far behind. Tune providing 1.9 grams of leucine per 3 ounce serving. One serving of our grass-fed whey protein powder provides 25 grams of protein and a full 2.546 grams of leucine! Additionally, it also provides 1.351 grams of isoleucine and 1.415 grams of valine for a total BCAA count of 5.312 grams and 11.404 grams of essential amino acids per serving.
Aid in Body Recomposition and Overall Health:
Whey protein isolate is the purest form of whey available at 90 percent pure protein and provides an excellent amino acid profile. Unlike whey concentrate, whey isolate has had the fat and carbs from its milk source filtered out, leaving you with what you want—straight protein to help you build muscle and change your body composition with no excess calories or sugar. This makes whey protein isolate an excellent choice for anyone who is watching their weight or maybe looking to lose weight.
A meta-analysis of nine studies showed that whey assisted overweight and obese individuals in losing fat and reducing risk factors for cardiovascular disease.
Whey’s benefits for the heart have been demonstrated in other research as well. A study in the journal Appetite showed that overweight subjects who strength trained and supplemented with whey protein had higher levels of glutathione (a molecule that supports cellular health) and HDL cholesterol after six weeks than a control group that exercised without supplementation.
Another trial from the International Journal of Food Sciences and Nutrition found a linear relationship between the amount of whey protein consumed and increases in glutathione levels. Subjects who took in 45 grams of whey daily for two weeks increased glutathione by 24%.
Supports Faster Recovery:
When you’re done with your training session, it’s time for your muscles to start their recovery process and rebuild themselves stronger and bigger. For this, they need protein and leucine. Whey protein isolate delivers its amino acids to muscles faster than other protein sources – including whey protein concentrate. A study from Medicine and Science in Sports and Exercise found that whey protein delivers leucine to the muscles faster, stimulating muscle protein synthesis sooner. This makes whey protein isolate the better choice post-workout.
The sooner you get protein (and the leucine within it) into your muscles, the faster you can begin to recover from your workout. From hard training athletes to weekend warriors who partake in multiple activities per day, fast recovery between sessions is critical. Whey isolate delivers leucine to the muscles more efficiently than other protein supplements, making it a must-have for any post-workout shake.
Other protein options can have their own advantages, such as casein. Casein digests more slowly making it better suited as a nighttime option before going to bed, so it can feed your body leucine gradually through the night as you sleep.
THE SOURCE OF OUR GRASS-FED WHEY
Setting the bar for a higher quality whey protein supplement starts with the quality of life and food the cows have who supply the whey protein. Our whey is derived from the milk of Montana dairy cows that graze pastures and feed on grass year-round. In the process, our dairy cows avoid feedlots, the need for feed supplements, and GMO foods, which often include pollutes that the cows consume and pass on in their milk. Grass-fed naturally produces a cleaner and high-quality whey protein supplement. (For more on grass-fed vs regular whey see here)
