Melatonin for my dog.
Actually, I buy it for my dog. Under the recommendation of my specialty vet, he takes it for hair loss that was being caused by another medication he is on. I thought she was crazy, or that I heard her wrong & Googled & sure enough, it's true. And it works. GNC had the strength I needed (it's done by their weight) with no artificial sweeteners added.

I Have tried them all. This is the BEST!
I could not sleep at all without my Melatonin. When the bottle starts to get low, I have to drive 25 miles into town to purchase it. Now, it comes to me. I hope GNC continues to do this auto delivery cause I have other supplements I take that I would be happy to try in the GNC line.
This stuff WORKS!! AND the 5 mg is super easy to swallow.

Works well for me
I started taking a few weeks ago, I found that the big box store brands were not working, so I tried the GNC brand. I found they don't dissolve so I take [2] 1 hour before bed and sleep well all night. Plus I wake up with no hangover feeling!!

BEST ANSWER: is this melatonin also used for pet skin growth?
Is this product Gluten Free? I noticed the label does not state Gluten Free but it has the same ingredients as the GNC 10mg Melatonin (Item # 109422) that does state it's Gluten Free.
