FAQ
What does low temperature processing mean for protein powders?
Low temperature processing aims to minimize denaturation and preserve protein quality by avoiding high-heat processing methods during production.
Are grass-fed whey proteins better?
Grass-fed whey often sources cows on pasture, which can influence fatty acid profiles and may appeal to buyers seeking a more natural sourcing approach. Nutritional differences are typically modest per serving.
Is unflavored protein better for digestion?
Unflavored or minimally flavored proteins often have fewer additives, which can improve digestion for some users, especially those sensitive to sweeteners.
Can I mix these powders into shakes or foods?
Yes. Most powders mix well with water, milk, or non-dairy alternatives. Isolate powders generally mix more easily than concentrates.
How do I choose between whey isolate and whey concentrate?
Whey isolate has higher protein per serving and lower lactose and fat, making it suitable for lean goals. Concentrates may be more affordable and suitable for general use.
