You already know that what you eat can impact everything from acne to mood, and while supplement powders can be a great addition to your diet, it’s key that you know exactly what you’re getting. A good rule of thumb is to avoid anything with additional sweeteners, additives, and ingredients you can’t pronounce. “What we put into our bodies shows on the outside,” Rachel Harvest, MS RDN CDN, a New York City-based dietician and lifestyle coach tells Refinery29. “Ashwaghanda and rhodiola are excellent support [ingredients], but it is important to know that, like any supplement, medication or food, some bodies handle them well and others do not. There really is no one- size fits all diet or dietary supplement regimen.” If you’re on the fence about a brand or ingredient, don’t hesitate to consult a dietician or doctor before integrating it into your diet.
