Build quality is evident in the transparent labeling and commitment to grass-fed sourcing. The 2.31-pound container offers 30 servings, making it a practical choice for consistent daily intake.

The product's performance in terms of mixing and taste is strong, but the high cost per serving could deter budget-conscious buyers.
Overall, Transparent Labs Grass-Fed Whey Protein Isolate earns a strong recommendation for those prioritizing clean nutrition and digestive comfort. It delivers on its promises of high protein content, purity, and amino acid completeness. If you are willing to invest in a premium protein source that supports both performance and health, this is an excellent choice.
Buying Guide: What to Look for in a Whey Isolate
Protein Content and Purity
When you compare isolates, grams of protein per scoop matter, but so does the source. Transparent Labs delivers 28g of protein per serving from 100% grass-fed, grass-finished American cattle. That is one of the highest protein-by-weight ratios available. Legion Whey Plus offers 22g per scoop from Truly Grass Fed certified Irish milk. Both are isolates, meaning minimal lactose and fat. But if you want the maximum protein boost per scoop, Transparent Labs takes the lead.
Ingredient Cleanliness and Sweeteners
Both brands avoid artificial sweeteners, food dyes, and preservatives. Legion uses natural flavors only (e.g., Chocolate and French Vanilla), with 0g added sugar and 0g lactose. Transparent Labs similarly uses naturally flavored, hormone-free whey, free from artificial anything. If you have a sensitive stomach or follow a strict clean-eating plan, either works. However, Legion also has third-party verification (ISO 17025 lab certified) for banned substances, which adds an extra layer of trust for competitive athletes.
