I test my pee in the morning, and it's fun to start the day off with an indication that I did well on my diet the day before!
I think that these strips won't be effective forever, because in "The Art and Science of Low Carbohydrate Living," the authors mention that after a few weeks of ketosis, the body begins to adapt.
"Within a few days of starting on carbohydrate restriction, most people begin excreting ketones in their urine.
"...But over a matter of weeks, the muscles stop using these ketones for fuel. Instead, muscle cells take up acetoacetate, reduce it to betahydroxybutyrate, and return it back into the circulation. Thus after a few weeks, the predominant form in the circulation is beta-hydroxybutyrate, which also happens to be the ketone preferred by brain cells (as an aside, the strips that test for ketones in the urine detect the presence of acetoacetate, not beta-hydroxybutyrate).
"In the kidney, this process of keto-adaptation is also complex. Over time, urine ketone excretion drops off, perhaps to conserve a valuable energy substrate (although urine ketone excretion never amounts to very many wasted calories). This decline in urine ketones happens over the same time-course that renal uric acid clearance returns to normal (discussed below) and thus may represent an adaptation in kidney organic acid metabolism in response to sustained carbohydrate restriction.Read more ›
And they are nicely sized for cutting in half to get twice as many per bottle. Makes the price a little nicer.
One important thing about purchasing an item like this though is to note the actual seller. This item (at the time of the review) is sold by one of Amazon's partner vendors. In fact, the one listed today is not the same as the one that mailed mine so do the due diligence on checking out the vendors. This also means that shipping charges may vary as can the actual product prices. The listing today is actually about 10 percent less than what I paid (oh well). Sometimes you can even find vendors that keep their stock in the Amazon warehouse system and get the products with Prime/Super Saving as well...but do pay attention as the vendor (or at least the shipping) can change between the time you add to your cart and the time you check out.
In any case, for those seeking to know their ketone status, this is a nice product--easy to use, easy to read, and reliable.

We bought theses after we started out Keto diet in hopes to get an idea when we are in Ketosis. These worked better than I thought they were going to! Read morePublished 20 days ago by Amy Westmoreland
I really love these. I do not purchase them online, however, because I imagine age/handling can effect quality. I go to the pharmacy and get them there. Read morePublished 2 months ago by Momma Green
