A sleep-related movement disorder known as restless legs syndrome creates an irritating urge to move the legs. The cause of this condition is still unknown; some researchers suggest that magnesium deficiency may be the cause.\u003c\/p\u003e\n\u003ch3\u003eGlycine for Sleep\u003c\/h3\u003e\n\u003cp\u003eGlycine is an amino acid that plays a key role in promoting restful sleep. It helps lower body temperature, enhance serotonin levels, and support relaxation, making it easier to fall asleep and improve sleep quality. Studies suggest that taking glycine before bed can lead to deeper, more restorative sleep without causing drowsiness the next day.\u003c\/p\u003e\n\u003ch3\u003eMyo-Inositol for Sleep\u003c\/h3\u003e\n\u003cp\u003eStudies have shown that myo-inositol (often simply referred to as inositol) can contribute to improved sleep quality and duration, making it an intriguing option for individuals seeking to optimize their rest. By acting as a precursor for important neurotransmitters like serotonin and dopamine, myo-inositol helps regulate brain activity and promote a sense of relaxation. Moreover, myo-inositol has been linked to reduced anxiety levels, a common contributor to sleep disturbances, thereby aiding in the overall sleep-wake cycle. With its natural origin and promising effects on sleep, myo-inositol presents a valuable avenue for individuals looking to enhance their sleep patterns and achieve a more rejuvenating and restful night's rest.\u003c\/p\u003e\n\u003ch3\u003eL-Theanine for Sleep\u003c\/h3\u003e\n\u003cp\u003eAccording to research, L-theanine may affect sleep by affecting neurotransmitters and helping promote relaxation in the brain's activity. L-theanine has a structure similar to glutamate, which is also a neurotransmitter that promotes sleep. Studies show that it also facilitates sleep through its effects on brain waves.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eApigenin for Sleep\u003c\/h3\u003e\n\u003cp\u003eApigenin sleep and relaxation benefits are largely accredited to its ability to reduce feelings of anxiety and increase feelings of sedation. This could largely be due to its ability to reduce cortisol levels.\u003cbr\u003e\u003cbr\u003eFirstly, Apigenin may reduce anxiety symptoms. A clinical randomised controlled trial found chamomile extract (standardised to 1.2% apigenin) to reduce feelings of anxiety compared to a placebo in those with an anxiety disorder. Secondly, a study performed on mice found Apigenin to augment total sleep time and rate.\u003c\/p\u003e\n\u003ch2\u003eSuggested Use for Sleep A.H.\u003c\/h2\u003e\n\u003cp\u003eFor best results, take 4 capsules 30-60 minutes before bed.\u003c\/p\u003e\n\u003ch2\u003ePremium Quality\u003c\/h2\u003e\n\u003cp\u003eAs with all \u003ca href=\"\/collections\/kratox\"\u003eKratox\u003c\/a\u003e supplements, Sleep A.H. is made using only the finest quality raw ingredients and is free from unnecessary additives, fillers, binders, colours and preservatives.\u003c\/p\u003e\n\u003ch2\u003eSuggestions for Better Sleep\u003c\/h2\u003e\n\u003ch3\u003eStart with the end in mind\u003c\/h3\u003e\n\u003cp\u003eFor example, if you'd like 8 hours sleep and you need to wake at 7am, aim to be in bed by 10:30pm, giving yourself 30 minutes - without a screen - to fall asleep.\u003c\/p\u003e\n\u003ch3\u003eLimit caffeine\u003c\/h3\u003e\n\u003cp\u003eCaffeine stays in your system a lot longer than you might think.
