Nitric Oxide Saliva Test Strips by Berkeley Test (50 strips)

Excellent for testing Nitric oxide in the body, We all need nitric oxide and these sticks will tell you where you stand. Please do not use a mouthwash when using test strips as the mouth wash will kill all the nitric oxide in your saliva. These strips are excellent for testing the strength of bodybuilding supplements, these are normally called NO boosters. These NO boosters mainly contain the amino acids arginine and citrulline.From food, the best 2 sources are Rocket leaves ( aka aragula) and Beetroot juice. Celery and rhubarb are other good sources. Please google for more information on nitric oxide.I have recently being informed the amino acid Carnitine in various forms also boosts nitric oxide.

Does exactly what it says on the tin.

These strips are so easy to use for an instant reading . The container allows them to be carried with you all day whenever you want to take a reading . This is first pack I have bought and I'm sure I'm going to be a repeat buyer . One slight thing is the price , they could be a bit cheaper but at the moment it won't discourage me

Rating says it all.

These strips don't work they will always indicate "depleted" no matter who it is that they are 'testing'. Tried on three different people two of whom were perfectly healthy. A complete and expensive waste of money.

i've been using the Berkeley strips for some months now and find them to work well. As a long distance triathlete, I've often practiced dosing on NO for a competitive advantage, however i was doing this blind, unable to measure the effectiveness of the various products and foods available. It was also difficult to figure out how long the effects would last after consumption of these NO sources.The Berkeley strips have allowed me to accurately measure the strength and decay for each product. You have to use them with a clean palate though, I recommend testing at least one hour after any food or drinks consumption, including water, as this effects the chemical reading on the saliva. Once you get in to a regime of testing, you find the best time to consume NO, and which products work best for you, and a pattern can be found for your individual response. Some of the results are surprising, for example a good sleep vs a bad sleep after NO consumption can change the reading from threshold to high, this is not something I'd realised before, or a heavy training session can drop your NO levels more than you thought possible. My personal view is that many people could be dosing at the wrong time, with a product that they do not respond well to, I think these test strips eliminate that obscurity and creates a clearer picture on an individual basis.

I like this NO tester, but sudently, all the rest of the strips stopped working. This was the second time I purchased these testers (50 strips each). I used 25 of them successfully and all the rest of the 25 became useless because all of them showed my NO low and depleted. I know that those readings are wrong. I'm disapointed

First time i tested i thought they werent working. Today it showed signs just like in dr office

I will do the best I can.

Not sure what I was doing wrong but couldn't get some to read when I tested

Inflammation is behind all chronic pain. Knowing the diagnosis is not enough. Getting to controllable sources of inflammation objectively is A#1. I've been using these test strips as recommended in the book, "Drop Acid" to monitor Nitric Oxide (NO) in saliva, a measure of inflammation (overstated so read the book) that can be reduced through diet, exercise, exposure to nature and daily restorative time. Having ways to self check NO is extremely valuable.
