Check your nitric oxide levels with the Nitric Oxide Saliva Test Strips by Berkeley Fit®. Just place the strip on your tongue to collect saliva and fold the strip in half. Within 10-seconds, the strip will change color reflecting the nitric oxide levels in your system.
For best results, test your nitric oxide upon waking in the morning and then have a nitrate-rich breakfast spinach and beet smoothie or a 2 oz. Red Ace Organic beet juice shot. Go to Red Ace Organics store and enter the coupon BERKFIT2 upon checkout to get 25% off your order.
