Cattle need salt. Trace mineral salt (red salt) is almost as cheap and "doesn't hurt" so it's frequently used. Pretty much the same with deer. Anything other than that only hurts your pocketbook. GNC is full of stuff that people don't really NEED, but because it might help they spend mega-$$$$$ for. I only object to people making or repeating unsubstantiated claims to get someone to buy something in order to line someone else's pocket. If, knowing that there is zero proof of efficacy, you choose to buy a high priced product full of vitamins & minerals etc. good luck with that. I hope your investment pays off for you.
