Really help sleep

Posted by iHerb Customer on Jun 18, 2017 | Verified Purchase

Really help sleep, and I am real insomniac , and very nervous person. But these give impression of falling asleep faster and sleep a bit longer. But besides that no sedative effect at all, so no bad effect.

Thanks for your feedback!

Not 75mg in size, 500mg at least, due to filler

Posted by iHerb Customer on Apr 11, 2017 | Verified Purchase

Maybe all magnesium l-threonate is like this, but I bought it thinking it was easier to swallow; however, THIS IS NOT 75mg IN SIZE but dosage. Ascorbyl palmitate somehow accounts for the remaining 425mg of filler... Also, it is not a particularly easily digested form--probably best to take on empty stomach.

Thanks for your feedback!

Excellent product

Posted by iHerb Customer on Apr 08, 2017 | Verified Purchase

This product has been suggested to me by a health practitioner. Has helped after surgery when anaesthetic affects memory etc and generally for the same. It is also being used successfully for one of my older dogs which has had seizures previously and another dog which is quite neurotic - both with success. They are small dogs so only require 1/4 capsule a day over their food.
