From the Research

The highest strength of valerian available in Australia as an approved product is typically found in tablet or capsule form, with a recommended dosage of 300-600mg taken 30-60 minutes before bedtime, although some products may offer higher strengths, as noted in studies such as 1. In Australia, valerian products are regulated as complementary medicines by the Therapeutic Goods Administration (TGA) and are available over-the-counter without a prescription. Valerian (Valeriana officinalis) is commonly used as a herbal remedy for insomnia, anxiety, and stress. Some key points to consider when using valerian include:

  • The standard recommended dosage for sleep issues is 300-600mg taken 30-60 minutes before bedtime
  • Valerian works by increasing levels of gamma-aminobutyric acid (GABA) in the brain, which has a calming effect on the nervous system
  • While generally considered safe for short-term use, side effects may include headache, dizziness, and gastrointestinal disturbances
  • It's essential to note that valerian may interact with certain medications, particularly other sedatives, so consulting with a healthcare professional before use is advisable, especially if you're taking other medications or have existing health conditions, as discussed in studies such as 2 and 3. The available evidence suggests that valerian might improve sleep quality without producing side effects, as seen in the systematic review and meta-analysis by 1. However, due to the presence of multiple active constituents and relatively unstable nature of some of the active constituents, it may be necessary to revise the quality control processes, including standardization methods and shelf life, as noted in 1. In conclusion, valerian could be a safe and effective herb to promote sleep and prevent associated disorders, but it is crucial to follow the recommended dosage and consult with a healthcare professional before use, especially when considering the highest strength of valerian available in Australia.
