Does apigenin help you sleep better?
There is currently no evidence that apigenin as a supplement meaningfully improves sleep in humans. Animal research is promising, but the only randomised study in humans showed no effect, so caution is warranted.
Apigenin, a compound that occurs naturally in chamomile, parsley and other plants, has shown clear sleep-promoting effects in mouse studies. The combination with magnesium extended sleep duration in mice by 32 to 44 percent, with the combination outperforming either substance on its own. That is a striking result, but it has only been established in animals.
In one large study of nearly two thousand Italian adults, people who obtained more apigenin through their diet slept better on average. That association was visible only in people with a healthy weight, however, and was entirely absent in people who were overweight or obese. Whether apigenin itself was responsible, or whether healthier eaters simply sleep better regardless, cannot be determined from this study.
In cell studies, apigenin has a two-sided effect on GABA receptors, the same receptors targeted by sleep aids and sedatives. At low concentrations it enhances the action of sedatives, but at high concentrations it inhibits that same receptor instead. What the net effect is in the living body remains unclear.
The only available study in which people were randomly assigned tested 50 mg of apigenin combined with magnesium and L-theanine in healthy, active adults over two weeks. That group saw no significant improvement in sleep quality compared with placebo. One caveat: apigenin was not tested on its own, participants were already sleeping reasonably well, and two weeks is a short test period. The group that took different supplements (without apigenin) in the morning did show improvement, which complicates the picture further.
All in all, research in humans is still in its early stages. There is currently no good evidence that apigenin as a supplement improves sleep in humans. The mechanism is biologically interesting, but the only RCT in humans shows no effect. For anyone with sleep problems: always discuss supplements or medication with your doctor.
This answer is based on mouse studies, cell studies, one large observational study of nearly two thousand people, a review article and one randomised study in humans that tested apigenin in combination with other substances. The only randomised study in humans is limited by its short duration (two weeks), the combination formula (apigenin was never tested alone), and the fact that participants were already sleeping well. The human evidence is thin and inconsistent.
Does taking glycine help you sleep better?
Glycine shows tentatively positive signals, but the evidence is thin and the only direct human study comes from the manufacturer itself. Anyone who wants to try it would be wise to view it as a complement to good sleep habits, not a replacement.
What can I do to sleep better?
CBT-I is the most powerful approach for persistent sleep problems; if you do not have access to it, ask your general practitioner about a shorter behavioural treatment of four sessions. Fixed sleep times, less caffeine and alcohol in the evening, and regular exercise are the best-supported self-help steps.
Does magnesium glycinate help you sleep better?
Magnesium may offer some benefit for sleep in certain people who are deficient or have a medical condition, but this has not been demonstrated for healthy people without a deficiency. If you have had poor sleep for years, first discuss with your doctor whether other causes may be involved.
Does CBD oil help you sleep better?
There is currently too little good research to say that CBD oil genuinely helps with sleep problems; if you suffer from them, there are better-supported options to discuss with your doctor.
How much melatonin should you take to sleep better?
If you want to try melatonin for difficulty falling asleep, 4 mg taken 3 hours before bedtime gives the best chance of effect; if you are 55 or older, only the extended-release form is officially recommended. Always discuss this with your doctor, as it concerns the treatment of a sleep disorder.
Does mouth taping help you sleep better?
For healthy sleepers, mouth taping has not been proven beneficial, and it is risky if you have a blocked nose. If you have sleep apnoea and are considering mouth taping, discuss it with your doctor first.
