I bought shakeology. I am nervous to try it.75 ingredients, some I've never heard of.  Could its ingredients cause allergic reaction. ?

Yes: Nicole, technically anything you ingest could cause an allergic reaction, although it is fairly unlikely. On the other hand, as a general principle of a healthy diet, if a food continues ingredients you can't even pronounce or have never heard of, you probably shouldn't eat or drink it. Stick to whole, unprocessed foods. Hope this helps! ...Read more

What are good treatments for hives like allergic reaction?

What are good treatments for hives like allergic reaction?

I will sometimes add h2 blocker such as zantac or pepcid, which also act as antihistamines. ...Read more
