Price and Brand Reputation
While it's not always the case, in many instances, you get what you pay for.
Established brands with good reviews and transparent sourcing often produce higher quality protein isolates.
Determine the Desired Absorption Rate
Different protein sources have varied absorption rates.
For example, whey protein is quickly absorbed, making it ideal post-workout, while casein, another milk protein, is absorbed more slowly and can be taken before bedtime.
If environmental impact is a concern for you, consider the sustainability of the protein source.
Plant-based proteins like pea protein tend to have a lower environmental footprint than animal-based proteins.
Consult with a Healthcare Professional
Before starting any supplementation, especially if you have medical conditions or take medications, it's essential to consult with a healthcare professional.
