Product FAQs

Is Kava Kava Root safe?

Kavakava root has been shown to have calming, muscle-relaxing and stress-reducing properties. The majority of people can enjoy the benefits of kava root when taken in moderation.  Since 1978 Crystal Star has focused on the functional benefits of whole herbs formulated with secondary and tertiary supporting ingredients.  The amount of Kava kava root in Relax is just a small part of the 11 whole herb formula.   However, we don’t recommend any form of kava for people with a history of alcoholism, pre-existing liver problems, or who are taking prescription drugs.

I’m under stress from work. What products will help me?

We recommend Relax or Adrenal Support. They both contain herbal nervines which have been used for centuries to encourage normal nervous system functioning.  They can also be used as-needed to ease chronic or acute stress symptoms. 

The adaptogens like ashwagandha in Relax help to calm anxiety and the Siberian eleuthero in Adrenal Support will help support the body and mind in times of stress.

Is Oat Straw Gluten-free?

Oat Straw does not contain gluten like other grains such as wheat, barley, and rye. It does contain a protein known as avenin that is well tolerated by most people with Celiac disease and those with gluten intolerance or sensitivity.  That said, even though the amount of Oat Straw is a very small part of the Relax formula, a small minority of people with Celiac disease may be more sensitive to it.
