How often can I use O+ products?

O+ can be used every day. We recommend using O+ any time you may be experiencing depleted oxygen levels – i.e., at a higher elevation, during and after intense exercise, where air pollution and stale air are prevalent, after a late night out. Note that all Oxygen Plus products are for recreational, intermittent use only. Prolonged use is defined as uninterrupted intake for more than 8 hours. WARNING: Persons with any type of health or medical condition should consult their physician prior to use of products.
