How safe is the valerian as a sleep and anxiety aid for most individuals, and people with spectrum ? can the overdose of valerian be life-threatening ? because, it's not regulated by the fda and it's sold as otc supplements, so, just how effective is?

Some studies suggest that Valerian may reduce the length of time it takes to fall asleep, but not all the studies agree. The proper dosage is unclear, and since supplements are not regulated by the FDA, product claims may be misleading. The dosage is also unclear. it’s probably not good to take a supplement on a regular basis for sleep. Consult your doctor for advice. Good luck.
