Before I review the actual product, I want to mention that the marketing really bothers me...they market this as a "holy grail" product. I got ads that mentioned "de-aging" and that it would help with my skin, hair, nails, bloating, wrinkles, immunity, digestion and more. Anytime I see something that is marketed to this degree, I'm skeptical and honestly bothered. I bought this for traveling. I travel all over the world for work and traveler's diarrhea is just a common thing you prepare for. One of the best and most effective products I've taken to help with traveler's diarrhea is Diaresq which is...you guessed it...bovine colostrum! I have taken Diaresq for years, but I liked that Armra had a smaller amount that I could take on a daily basis while I'm traveling. I took it for about a week before my trip, during my trip (3-weeks) and 1 week after the trip. What were some things that I noticed? It's impossible to attribute any of these things to Armra specifically (both the good and the bad). The good was: I didn't get sick the whole trip, I had regular bowel movements right from the get-go (which often doesn't happen), and I guess you could say that I had less bloating than normal. The bad was: I did have an upset stomach multiple times while taking this. Not every time, but every so often. As well as stomach pains. I'm not lactose intolerant, so I'm not sure if it was related to this or not. Challenges in using the product: Two things about using the product itself. The first is that the unflavored still does taste like bovine colostrum- so if you're sensitive to taste/smell, if you take this straight, it will bother you. Second, I did try to mix this into my cold beverages, but 1. it doesn't mix well, it gets clumpy and 2. because it's milky, it gives your beverage a weird frothy texture. Okay if you're drinking an iced latte. Really weird/gross if you're drinking a juice or something like that. All in all, I'm not sure if I'll use this again - perhaps for a future trip, but I doubt I will take this on a daily basis.
