What owners say about Life Extension

3/5

“Honestly my routine got better but nothing really improved my sleep until I started taking magnesium l-threonate and melatonin 300mcg 6-hour timed release both from life extension.”

4/5 Stomach upset

“i've been trying magnesium glycinate for a while now and it does seem to help me wind down a bit before bed.”

4/5 Calming

“Small follow up: I tried Life Extension magnesium for my nighttime anxiety, and it's a nice addition to my evening routine.”

4/5 Cost

“For me, the threonate really is worth the money and I highly recommend it, the melatonin is more likely to work for you though so if you only want to try one thing try that one.”

“Honestly, it's not a miracle, but magnesium glycinate can really help with that wired feeling before bed for some people, and I've just always stuck with the life extension brand because it works for me.”
