Why Nula comes in gum form

Nula fits in the gap between one meeting and the next. Peppermint gum is easy to carry and needs no water or mixing.

What researchers have studied

In a 2009 crossover study by Scholey and colleagues, 40 adults completed laboratory tasks with and without chewing gum. The chewing condition was associated with lower reported stress and salivary cortisol.

The findings are mixed. A 2011 re-examination by Johnson and colleagues did not find the same reduction in cortisol or reported stress. Neither study tested Nula.

What that means for Nula

These studies do not establish how quickly Nula works, how its ingredients are absorbed, or whether it works faster than a capsule. A result for another gum or an individual ingredient cannot answer those questions for this product.

The reason to choose the format is practical: a pouch of peppermint gum can come with you. Read our review of L-theanine research and directions for use for product details.
