Kava is a tropical evergreen shrub with heart-shaped leaves and woody stems. Its scientific name is Piper methysticum. The roots of the kava plant contain compounds called kavalactones. These compounds are responsible for many of kava's beneficial effects.
Yellow color.
Kava is a natural alternative to prescription sleep medications. While it's effective at treating stress-induced insomnia, its effects on otherwise healthy people are unknown.
Dosage:
Experts recommend that your daily intake of kavalactones does not exceed 250 mg.
An effective dose of kavalactones is 70-250 mg.
Kava supplements may list kavalactones in milligrams or as a percentage. If the content is listed as a percentage, you will need to calculate the amount of kavalactones it contains.
For example, if one capsule contains 100 mg of kava root extract and is standardized to contain 30% kavalactones, it will contain 30 mg of kavalactones (100 mg x 0.30 = 30 mg).
To reach an effective dose within the range of 70-250 mg of kavalactones, you would need to take at least three capsules of this particular supplement.
Most extracts of kava root contain 30-70% kavalactones.
