You can drink protein powder during a workout, but it is not necessary for most people and may not be the best option for everyone. Drinking protein powder during a workout may slow down digestion and potentially lead to discomfort and cramping. Additionally, the body has limited capacity to use protein for energy during exercise, so consuming protein during a workout may not provide much benefit in terms of performance or endurance.
For most people, it is better to wait until after a workout to consume protein powder. This allows the body to focus on using carbohydrates for energy during exercise, while still providing the necessary building blocks for muscle repair and growth after exercise. Consuming protein within the first hour after a workout has been shown to be most effective for maximizing muscle protein synthesis and promoting recovery.
It's important to note that individual needs and preferences will vary, and some people may find that drinking protein powder during a workout works well for them without any adverse effects. Ultimately, the best approach will depend on the individual's goals, nutritional needs, and tolerance.
