Inicialmente, lo compré para poder dormir bien, las recomendaciones fueron muy buenas. Tengo que ser honesta, apenas lo estoy empezando a usar, y parece que sí me está funcionando y eso que sólo me tomo 1 cápsula al día. Pero también me llamó la atención que ayuda al hígado y a los riñones, eso me parece excelente porque traigo un tema con el hígado, veré con el tiempo cómo reacciono. Read more

Wow - this supplement was recommended to me by a friend who works in life sciences / biotech to help with insomnia. Since 2018, I’ve found several times a week (and every night in the week before my period) I wake up around 1am sweating and wide awake. I can’t cool down until 5.30/6am by which point it’s nearly time to get up for work. I’ve seen doctors, tried other supplements and nothing has worked and even air conditioning can’t cool me down when it happens. Glycine apparently not only increases production of melatonin but also lowers your body temperature. I’ve been taking 5g a night (for insomnia studies have shown 3-5g a night to be effective) the last 11 nights (since it arrived) and I have slept through 7 to 8 hours straight. This also covered my monthly terrible sleep week. The last few nights I tried without air conditioning as an experiment - and still I slept through. I have never had a stretch like this. I will update in a few weeks time but I’m hopeful I’ve at last got to the bottom of my insomnia! ***Update - 15 June 2022 - I am still amazed by this and my partner is now taking it too who is also a bad sleeper (we have separate rooms as a result!). I’ve upped my intake to 6-8mg before bed. It helps me get back to sleep more quickly if I do wake up (it used to be hours, now a few mins or so), generally increases the length of my total sleep and I have more dreams, which I assume means I’m sleeping more deeply. I slept 8.5 hours last night 😃 Read more

Recommend to me by a friend (a pharmaceutical chemist) who takes it as a sleep aid. I tried it and it works. She takes three capsules one hour before bed but I only need one. It does help me to sleep w/o waking up as often throughout the night. No side effects at all, so it replaced a more expensive supplement by another manufacturer that I was taking before. I’m really pleased about that! And very good price. Read more
