Hi, everyone! Thanks for supporting each other and sharing your experiences. My name is Rachel, and I am one of the resident Nutritionists here. I’m here to support you and answer any questions you might have! Probiotics are excellent for both digestive and immune support, and I recommend a broad spectrum product, unless otherwise specified by a practitioner. The Renew brand sold here is great, and I also love Pure Encapsulations brand, which can be found on Amazon.
