Caffeine in Whey Protein Powder

Caffeine is a natural stimulant that’s one of the most commonly used ingredients in the world. It’s found mostly in coffee, tea, and cacao plants. 

By stimulating your brain and central nervous system, it has several beneficial effects when consumed on its own or when added to whey protein powder.

Whey protein powder is made from whey using the liquid part of milk that separates during cheese production. It’s the watery byproduct formed as a byproduct.

Supplement brands are now combining caffeine with protein powder to give you a great-tasting, nutritious shake that provides the benefits of both compounds.

Tips for Choosing the Best Protein Powder With High Caffeine Content

When choosing the best protein powder with caffeine, follow the tips below:

Decide Your Workout Goals

The best protein powder with caffeine depends on your workout goals. If you’re trying to lose weight, look for a lower calorie powder with fewer carbohydrates and fat.

If you're trying to bulk up, using a caffeinated protein powder with more calories might be the better choice. 

Check the Caffeine Amount

Whilst the amount of caffeine included in protein powders isn’t huge compared to coffee, it still has an effect when consumed regularly and alongside other caffeine sources.

Look to consume around 3-6 mg of caffeine per kg body weight (~200-300 mg total). Anything above that may cause negative effects depending on individual tolerance.

Choose the Right Flavor 

Popular caffeinated protein powder flavor choices include cappuccino, latte, mocha, and caramel. Consider the normal coffee flavor you like to drink and base your protein powder choice on that. 

Consider Your Budget

Whatever your budget, cost should be taken into account. When deciding which one to buy, check the price of your caffeine protein powder and compare it to the quality before deciding if to purchase. 

The price of protein powder can vary greatly depending on added ingredients and the quality of protein included. Make sure to take these factors into account before deciding on the most suitable choice for you.
