Selecting the right protein supplement is not just about grabbing the most popular powder on the shelf—it requires careful consideration of your fitness goals, dietary restrictions, and personal preferences.

Safety and Side Effects of Protein
While protein supplements are generally safe, excessive use or poor-quality products may cause issues. Awareness of potential side effects ensures responsible consumption.
