I have posted several times here about what I take for sleep. I recently discovered amino acid l-ornithine. I take one about 15 minutes before bed (in addition to everything else I take) and I am out like a light in 15 minutes. I wake up once to go to the bathroom and then right back to sleep. I'm able to cut out the benadryl and valerian root now, but still take everything else which is below. This is what I've read about l-ornithine from manufacturer's website: "Ornithine is a non-essential amino acid and is manufactured by the body. Since the body can produce ornithine, a deficiency of this non-essential amino acid is rare and it is abundant in protein foods such as meat, fish, dairy, and eggs. "Ornithine is important since it: "Induces the release of growth hormone in the body, which in turn helps with fat metabolism Required for a properly functioning immune system and liver. Assists in ammonia detoxification and liver Rejuvenation Helps healing and repairing skin and tissue and is found in both these body parts. Unsupported claims that ornithine promotes muscle building, but this has not been proven. Helpful for people recouping after surgery and athletes may benefit from this nutrient." This says nothing about sleep, but I learned about it somewhere else and it WORKS. I also take the following: 5-htp (hydroxytryptophan) - amino acid which converts to serotonin in the brain. I take it on an empty stomach, 50 mg. late morning and 50 mg. late afternoon. Seriphos (phosphorylated serine) - saliva test revealed high cortisol levels - this helps lower them. I had the testing done through Clymer Healing Reserach in Pennsylvania and get Seriphos from them (all was done over the phone, by mail & e-mail, I'm in California). High cortisol levels interfere with sleep & relaxation. I've recently read about an herb, magnolia officinalis, which is also supposed to help lower cortisol levels - this website sells a product called Relora, which I may try in place of the Seriphos. GABA - amino acid which has a calming effect, it's very good, I take it before bed. l-theanine also works well, I think it helps the body to produce GABA ZMA (zinc/magnesium supplement) - from this website, I take 3 before bed Coral calcium - I take during the day with meals omega 3 essential fatty acids - our brains are 75% fat, they need these to function properly, I've recently started supplementing with flaxseed oil and fish oil which I take during the day w/food. Magnesium - besides the ZMA at night, I take magnesium and malic acid (as magnesium malate) during the day w/food and I think this helps with energy as well as sleep. I've also read we need some sunshine each day for our bodies to produce their own melatonin so that's important too.
