There’s no denying that this product is the cheapest on this list, and it’s definitely a popular choice among the budget conscious. You’re essentially getting two 125-strip bottles for the price of one.

The Advantages of Ketosis Strips

Following a ketogenic diet, taking keto supplements, and entering the state of ketosis has a long list of health benefits besides helping you lose weight.

All About Convenience

Using ketone urine strips is as easy as taking a urine sample in a clean container, holding the end of a strip in it, and waiting for a few seconds for it to change color. Afterwards, you can easily compare the color of the end of the strip with the chart typically found on the packaging.

Yes, a ketone breath analyzer is a more convenient way of determining if you’re in ketosis. But, research suggests that the amount of ketone body in one’s breath isn’t consistent even in the early stages of nutritional ketosis – in a study, only 9 out of 11 test subjects tested positive.

save money

On the Matter of Price

The price of ketone strips range from 8 to 10 USD for a pack of 50 strips. With the recommended testing frequency of once per day, the test strips would only cost you 20 cents per day.

Compare this to ketone breath meters and ketone blood test kits; you are not investing a significant amount of money right off the bat. To illustrate, a breath meter would cost around 200 to 300 USD, while a blood test kit would be 100 to 150 USD (might include a set of blood ketone test strip).

Precision Xtra, which is a blood ketone meter, typically sells for around a hundred dollars. The kit only contains ten strips for checking ketone production.

Also, while capable of testing blood glucose, the kit doesn’t contain strips for that purpose. This means those following a low-carbohydrate diet despite having diabetes or insulin problems will have to spend more.

Confirmed Accuracy

In a study, 12 individuals following a low-carb diet was observed. The subjects were tested for ketosis through their blood and urine.

There were no instances wherein the readings from the blood and urine testing contradicted each other.

Although there’s criticism that ketosis strips are inaccurate in later stages of ketosis, research shows that consistent readings can be achieved. It’s safe to say that in most cases, using strips is more than enough.

Offers What You Need

When testing, all you need to know is whether your body is in ketosis – especially if you’re following a low-carb diet mainly to burn body fat. You don’t need to know the exact amount of ketone bodies in your blood.

Ketosis strips suffice for this purpose, being something recommended by both researchers and medical practitioners for measuring acetoacetate.

The Verdict

All things considered, our recommendation goes to SmackFat Ketone Strips.

With the product being quite versatile, you don’t have to purchase another brand if you decide to go Atkins or paleo. In addition to that, it shows consistent and accurate readings on urine samples.

And, if your purchase goes bad before the expiration date, you can easily take advantage of the lifetime warranty. So, with SmackFat, you’re essentially making a risk-free purchase.

It’s true that you can’t go wrong regardless of which product you pick – the strips serve a fairly straightforward purpose after all. Still, if you’re looking around for the best ketosis strips, you should really consider SmackFat.
