Here are four natural products that can help improve sleep quality—without the deleterious side effects.

The most popular natural aid for sleep is melatonin. Supplementation with melatonin has been shown in several studies to be very effective in helping induce and maintain sleep in both children and adults, and in both people with normal sleep patterns and those with insomnia. However, the sleep-promoting effects of melatonin are most apparent if melatonin levels in the body are low. In other words, using melatonin is not like taking a sleeping pill. It has a sedative effect only when one’s melatonin levels are low.
Melatonin supplementation appears to be most effective in treating insomnia in the elderly, in whom low melatonin levels are quite common. A dose of 3 mg at bedtime is usually enough, because doses as low as 0.1–0.3 mg have been shown to produce a sedative effect when melatonin levels are low.
Melatonin appears to have no serious side effects as long as one takes the recommended dosage.

5-HTP (5-hydroxytryptophan)
5-HTP is converted in the brain to serotonin—an important initiator of sleep. It is one step closer to serotonin than L-tryptophan, and has shown more consistent results in promoting and maintaining sleep, even though used at lower dosages.
One of the key benefits of 5-HTP is its ability to increase REM sleep (typically by about 25%), while increasing deep sleep stages 3 and 4 without lengthening total sleep time. The sleep stages that are reduced to compensate for the increases are non-REM stages 1 and 2—the least important stages. To take advantage of the sleep-promoting effects of 5-HTP, the recommended dosage is 50–150 mg, 30–45 minutes before retiring. Start with the lower dose for at least three days before increasing it if necessary.

When taken together, the above three ingredients exert synergistic effects to promote restful sleep. NOTE: At higher single dosages, e.g., 600 mg, L-theanine does exert a sedative effect.

In terms of herbal medicine, there is no question that valerian (Valeriana officinalis) is the most popular remedy for insomnia. Recent scientific studies have substantiated valerian’s ability to improve sleep quality and relieve insomnia. In a large double-blind study involving 128 subjects, it was shown that an aqueous extract of valerian root improved the subjective ratings for sleep quality and sleep latency (the time required to get to sleep), but left no “hangover” the next morning.

In a follow-up study, valerian extract was shown to significantly reduce sleep latency and improve sleep quality in sufferers of insomnia and was suggested to be as effective in reducing sleep latency as small doses of benzodiazepines (Valium).

The difference, however, arises from the fact that these drugs also result in increased morning sleepiness. Valerian, on the other hand, actually reduces morning sleepiness. As a mild sedative, valerian may be taken at the following dose 30–45 minutes before retiring: dried root (or as tea): 1–2 g; tincture (1:5): 4–6 ml (1–1.5 tsp); fluid extract (1:1): 1–2 ml (0.5–1 tsp); or valerian extract (0.8% valeric acid): 150–300 mg.

If morning sleepiness does occur, reduce the dosage. If the dosage was not effective, be sure to eliminate those factors that disrupt sleep, such as caffeine and alcohol, before increasing the dosage.
