I’m always searching for effective, safe and readily available sleep enhancing nutrients to test them myself as well as make effective recommendations for my clients.
In my previous post I talked about how calming minerals magnesium and calcium promote more restful and uninterrupted sleep.
In addition to magnesium and calcium, the other highly effective sleep enhancing nutrients are inositol and L-theanine, they are available for purchase from chemists, health food shops or online. Naturally, quality is always important as it’ll determine your results so choose the supplements wisely!
INOSITOL
Inositol taken before bedtime improves sleep quality for many people, helping with falling asleep and quieting the busy mind.
It also facilitates a feeling of calm, decreases anxiety, and alleviates depression and panic attacks. The supplement can be purchased without a prescription in the form of capsules or powder.
Dose guidelines
A therapeutic daily dose of inositol for better sleep is between 750–2,000 mg for adults. Higher doses are more effective for insomnia, and lower doses for difficulty falling and/or staying asleep.
Inositol is best taken 20-30 minutes before bed on a regular basis over a few months for best results.
Food sources
Citrus fruits, seeds, rock melon, brewers yeast, wheat germ, whole grains, navy beans and oats. Animal sources include eggs, and organ meats such as liver.
L-THEANINE
L-theanine is a biologically active component found in the leaves of green tea (Camellia sinensis), responsible for its relaxing properties and distinct taste. However, the small amounts of L-theanine found in tea will not have the desired calming therapeutic effect.
Supplementation is the most efficient way to reach the therapeutic dose (see below), unfortunately most cheap supplements are low in L-theanine and thus are ineffective.
Importantly, L-theanine will not make you drowsy, sleepy or tired when taken during the day.
Taking L-theanine during the day may actually help you be more relaxed at bedtime, and taking some before bedtime may also help you to relax and reduces anxiety so that you find it easier to get to sleep and stay asleep.
It also supports cognitive function and memory.
Dose guidelines
Studies suggest that taking between 100-400 mg/day of L-theanine may have a relaxing effect that helps with sleep quality. In a 6-week study of boys with autism, 400 mg of L-theanine (200 mg in the morning and 200 mg at dinner) was shown to significantly improve sleep quality by increasing the time spent in restful sleep.
Food sources
Green tea.

thanks for this information
Hi Joanna,
thank you so much for the really insightful information. I would like to take inositol to improve my sleep. By the dosage you described, did you mean that 1000mg would be better for difficulty falling and/or staying asleep and 2000mg would be better for insomnia?
Yes, that’s right – 2g would work better for insomnia than 1g.
Cheers
Joanna
Thank you so much for the response!! :) So if I take 2g Inositol would it work „worse“ than 1g if I only have problems falling asleep and staying asleep? Or could I take 2g directly as a precaution?
Hi Joanna,
thank you so much for the reply!! It’s very helpful :)
I just have one more question to clarify. Could I also take 2g of inositol directly as a precaution or would it be less effective if I only have problems falling asleep and staying asleep? (no insomnia yet)
Have a great week!
Cheers, Lena
Hi there
You’d need to experiment to see what dose works for you. I suggest you start with 1g for a few weeks and see how this works, if no change then increase to 2g and again see how this works for you.
Thanks for sharing about sleep-enhancing nutrients: inositol and L-theanine that I really needed.
I’m glad the information was of help.
hey Joanna Sochan, Its really information
You’re welcome!
Hi Joanna,
Thank you for the informative article but I’ve tried L-theanine for sleep and it gives me insomnia, probably because of the caffeine content!
However, it does promote a sense of well-being for me.
Sleep wise I’ve had much better luck with GABA and high dose fish oil.
Yes, L-theanine can have the opposite effect on some people, therefore it’s important to try a few nutrients to see which one(s) work for you. We are so different when it comes to foods and supplements!
Good to know about a combination of GABA and fish oil.
Yes! Agreed! I like I purchase on Amazon.
I have just started giving it to my 8 & 9 year old sons. My oldest is on the autism spectrum, never been medicated. I hope this might be something positive to help him focus and stay calm in high stress situations, and just w general anxiety or panics feelings.
It has really helped me, just as you described above.
Thanks for the blog!
