The supplement industry is booming right now. They use your emotions to get you to buy BS products and believe in them. Unfortunately supplement company’s aren’t regulated right now. Unless they are labeled ORGANIC. Sure some of them work because they have a good ratio of protein fats and carbs and are usually taken with exercise as well but that doesn’t mean they aren’t filled with fillers. I.E) concrete and saw dust.
That is why I prefer to invest in whole foods. For example I would prefer to drink a smoothie with non fat greek yogurt, greens, healthy fats like ground flax-seed and fruits than a protein shake. I know I’m getting the nutrients with no added fillers.
If you absolutely need the protein shake to reach your calorie goal then make sure it’s organic because they do have a few regulations.
Don’t let the supplement company sell you magic pills. It’s not magic. It takes hard work and healthy choices consistently made.
