MariGold Grass-Fed Whey Protein Isolate is a peanut butter protein powder for pre- or post-workout drinks and recipes, with 20 g of protein per serving in a 1 lb bag.
This whey isolate is made for people who want to add protein to their workout routine or everyday food without giving up a peanut butter flavor. Mix it into a shake or smoothie, or use it in a baked high-protein treat. Its processing and ingredients are chosen for specific attributes, from the source of the whey and peanuts to how the powder mixes.
MariGold Whey Protein Isolate can be used before or after exercise as a protein boost. Protein helps support the creation, protection, and repair of muscle tissue, which can contribute to lean muscle, endurance, strength, and recovery. Each serving provides 20 g of protein, and the 1 lb bag contains 15 servings.
Organic peanut flour made from peanuts grown in the USA gives this whey isolate its roasted peanut taste. The formula also uses milk from grass-fed cows and carries Truly Grass-Fed certification. The peanut butter flavor is intended for shakes and smoothies as well as baked high-protein treats.
The whey is cold processed and microfiltered, leaving it undenatured. This processing retains natural nutrients, antioxidants, amino acids, and minerals. For mixing, the powder is instantized with non-GMO, choline-rich sunflower lecithin, which helps it disperse quickly in beverages and other solutions.
The peanut butter formula includes L-glutamine, which is included to help support a strong gut lining and aid digestion and absorption of nutrients. MariGold is Non-GMO Project Verified and free of antibiotics, rBST, hormones, gluten, and lactose. It contains no added sugars.
This protein powder is suited to shoppers seeking a grass-fed whey isolate with peanut butter flavor for workout drinks, smoothies, or baking. Its defining fit is a 20 g protein serving paired with organic USA-grown peanut flour and a mixable format.
