If I am lactose intolerant what is the likelyhood of me mortal allergic to casein?

I would like to know because i bought a supplement that contains minute amounts of casein. When I chomp through things with lactose i carry an upset stomach. Up to 75% of the world is lastose intolerant. Only 3% of the world is allergic to milk which contains casein (milk protein). If you were allergic to milk casein you would own skin breakouts (rashes and itching) and it is usually diagnosed as a baby. If you capture an upset stomach, etc. you are lactose intolerant. The casein in the supplement shouldn't bother you. If you call for more information just email me. Good luck!
