1. Isopure Low Carb 100% Pure Whey Isolate Protein Powder
- Brand: Isopure
- Manufacturer: Isopure
Isopure is renowned for its clean and effective formulations, and their Low Carb Whey Isolate in Dutch Chocolate flavor lives up to the reputation. With 25 grams of protein per serving and zero grams of sugar, this product is tailored for individuals who prioritize a low-carb, high-protein diet. The inclusion of vitamins and its keto-friendly profile further enhances its appeal. The Dutch Chocolate flavor offers a rich, satisfying taste, making it a standout among flavored protein powders.
Performance-wise, Isopure excels in mixability and ease of digestion. It blends smoothly with water or milk and leaves no chalky residue, ensuring a pleasant user experience. The lactose-free formula is particularly beneficial for those with sensitivities, and the added vitamins support overall health. However, its relatively smaller serving count (62 servings per container) compared to competitors may be a consideration for heavy users.
Pros
- Low-carb and zero sugar formulation
- Rich Dutch Chocolate flavor
- Lactose-free and gluten-free
- Keto-friendly with added vitamins
Cons

2. Nutricost Whey Protein Isolate (Cookies N Cream) 5LBS
- Brand: Nutricost
- Manufacturer: Nutricost
Nutricost’s Cookies N Cream Whey Protein Isolate offers 30 grams of protein per serving, the highest among the products reviewed. Manufactured in an NSF Certified, GMP-compliant facility, it emphasizes quality and safety. The flavor is indulgent and ideal for those who enjoy dessert-like protein shakes. However, it’s important to note that this particular flavor contains gluten, milk, and soy, which may limit its suitability for some users.
In terms of performance, Nutricost provides excellent mixability and a creamy texture that enhances the flavor experience. Its higher protein content per serving makes it particularly suitable for athletes or those with higher protein requirements. However, the presence of allergens such as gluten and soy may be a drawback for individuals with dietary restrictions, and the serving count (55 servings per container) is slightly lower than expected for a 5-pound container.

- High protein content (30g per serving)
- Creamy Cookies N Cream flavor
- Manufactured in GMP-compliant facility
- Good mixability
Cons

NOW Foods stands out for its purity and quality assurance. The product is GMP-certified and comprehensively tested, ensuring reliability and safety.
