There are many natural remedies for anxiety and nervousness. However, only kava and inositol have multiple randomized controlled trials showing that they are effective for anxiety.
Kava is from the roots of Piper methysticum, a plant. Multiple studies show that kava is effective for anxiety. However, kava has significant treatment-emergent side effects. Kava use carries a risk of developing liver toxicity and liver failure. Because of this severe side effect, kava is not recommended as a treatment for anxiety.
Inositol is a carbohydrate and is found in fruits and lechitins. Inositol also has multiple studies showing that it is effective for anxiety. In addition, inositol has very few side effects. Therefore, the best natural remedy for nervousness is inositol.
You can find inositol in Kalmpro, which is a natural supplement that contains a proprietary blend of inositol, L-theanine, passionflower, lavender, and lemon balm. In addition to inositol, the other natural ingredients in KalmPro also have studies that they are effective for anxiety, and have very few side effects.
