hubby takes this one and i take the reg. see my review on that.
Who knows, but between this product and the green tea and tulsi tea, I DID get the cold, just not as bad as hubby. I believe that it works.
I take one melatonin (one 5mg) capsule. Then I tried adding 1 tryptophan, then 2. 3 made kind of strange things happen, so I knew that since I felt better on the 1 melatonin + 2 L-tryptophan saps that I had found the correct dosage for me. I get much better sleep with these products.
