Look, I don’t care how you spend your money.
If you want to buy the newest iPhone, who am I to tell you how to spend your money? If it’s important to you, then it’s not a waste of money.
If somebody wants to buy protein powder or pre-workout, then who are you to tell them how to spend their money? If they like them and can afford them, what’s the harm?
The only time I’ll agree that supplements are a waste of money is if you invest in fat burning supplements, because they’re a straight-up scam with no benefit whatsoever.
If you can afford a supplement, you like it, and it’s not harming you, then good for you! Do you need BCAAs? Likely not. That’s why they’re a supplement (which are called supplements for a reason- they literally supplement a healthy diet). BCAAs can be helpful if you’re not getting adequate protein, but otherwise they might not be needed.
Does that make BCAAs a waste of money? No. If you like taking them and can afford them, then that should be enough reason.
You don’t NEED the new iPhone. I’m sure having extra wide camera lenses is great, but you’ve done just fine to this point without them. That being said, it’s not a waste of money if you can afford it and it’s important to you.
Don’t bash people for wanting supplements. If you’re truly concerned and want to help, EDUCATE them on why they may or may not need a certain supplement, but don’t belittle them and make them feel like they’re wasting their money. It’s their money, not yours.
