Frequently Asked Questions

What is Cyracos lemon balm extract?

Cyracos is a patented lemon balm extract standardized to contain greater than 7% rosmarinic acid and greater than 15% hydroxycinnamic acid derivatives. It was developed by Naturex and used in the Cases et al. (2011) clinical study that showed a 49% reduction in anxiety and 39% reduction in insomnia. Cyracos is considered the most clinically validated form of lemon balm and is available in several commercial supplement brands.

Can lemon balm affect thyroid function?

Yes — lemon balm has been shown in laboratory studies to inhibit TSH (thyroid-stimulating hormone) binding and may reduce thyroid hormone production. People with hypothyroidism or those taking thyroid medication should use lemon balm with caution and consult their healthcare provider. For people with normal thyroid function, standard supplement doses are unlikely to cause clinically significant thyroid effects.

Is lemon balm better for anxiety or sleep?

Lemon balm is effective for both, but its strongest evidence is for anxiety-related insomnia — it addresses the underlying anxiety that prevents sleep. For pure sleep support without anxiety, valerian or melatonin may be more appropriate. Lemon balm is particularly useful for people whose sleep difficulties stem from a racing mind or stress, as it calms mental chatter without heavy sedation.
