Best Ketone Test Strips of 2025

"I've been using these strips for years on Keto and Carnivore diets. The negative reviews come from people who mistakenly believe they're in ketosis. From my experience, it takes about three full days to get back into ketosis after eating carbs. These strips work great if you follow the instructions. I've tested them against hospital results, and they're quite accurate. Don't be swayed by bad reviews; it's not the product's fault!"

"As someone new to the keto lifestyle, these test strips have become essential for keeping me on track. They're super easy to use, and I appreciate the quick feedback since I’m not the most patient person. The clear color chart helps me gauge my progress accurately. The bonus eBook and app provide valuable insights and tips, making it easier to navigate my diet. If you're curious about keto or serious about it, these strips are a reliable and affordable tool!"

"I appreciate that these strips provide enough tests to check throughout the day. After a high reading, I panicked, but I remembered to stay hydrated, which is crucial while in ketosis. The strips help verify my hydration level, guiding me to drink more water if needed. They are a great tool for anyone on this journey!"

"These strips are affordable and so easy to use for monitoring my ketone levels!"

"Although the strips worked well initially, they only lasted two months after opening, and I found some inconsistencies with the colors."

"I find it much easier to track my progress with these strips!"

"I found these strips to be very effective for indicating ketosis. I noticed a significant difference in the results from older strips compared to fresh ones, especially after 90 days. Overall, I'm satisfied and plan to purchase another bottle in a couple of months."

"When I hit a plateau on my keto journey, these strips were incredibly helpful. They allowed me to check if I was still in ketosis and figure out how to get back on track when I slipped out."

"I used these strips all the time during my keto diet. They were super easy to handle and gave me the results I needed."

"I was really excited to try these strips! After reaching out, the company offered a replacement, and my new batch showed a 1.5 mM range of ketones. I’ve been keeping my carbs under 50g, and it's great to finally see results. Just avoid storing them in humid places!"

"I really wanted these test strips to work because the Ketostix are so expensive. The first batch was decent, but the second batch was useless—they arrived purple even when dry. I wish they would fix the color chart; it's hard to read at lower levels of ketosis."

"I find these strips very simple to use, and they seem accurate and easy to read. The price is reasonable, and I will definitely buy again!"

“I bought this to measure my ketones due to diabetes. It's quite accurate compared to urine test strips and easy to use. I appreciate the convenient carrying zipper pouch. I've used it three times already and I'm satisfied so far.”

“Although the device is very pricey, it works easily. I find it a bit challenging to open each Keto strip, so I use small scissors. However, with just a small blood sample, I get quick results and would highly recommend this product.”

“In my journey to lower my high morning fasting numbers, I unintentionally started ketosis. I bought this ketone reader to monitor my levels as I'm aware of the health risks of going too far with keto. It's easy to use alongside blood glucose tests and provides fast results. I'm really happy with my purchase.”

"I find these strips helpful for tracking my progress on a keto diet, and they are easy to use overall. I appreciate the quick results they provide. Most of the time, they seem to work well, but sometimes the color doesn’t match the chart, which can be a bit tricky. Despite this occasional inconsistency, they are still useful for giving a general idea of my ketone levels, and for the price, they are worth it for anyone serious about a low-carb lifestyle."

"I purchased two bottles initially and then got another for work. Unfortunately, several strips were defective; some had no test strip at all, while others were inconsistent. I eventually tried a keto mojo product, and the difference was astonishing. I found this product to be extremely inconsistent, and I'm now throwing away all three of my half-used bottles. The performance is just not worth it."

"I tested myself twice and noticed the strip was a really light pink. From my understanding, that's not a bad sign; it just means that I'm using fat for energy instead of it spilling into my urine. Overall, I'm satisfied with what the strips indicate."

"These strips really helped me on my keto journey. It's great to know when I'm in ketosis, and the strips have been reliable for my testing."

"I've tried many brands, but these are the best I've found so far. They offer great value and I appreciate how they hold me accountable for my keto diet."

"I bought this two-pack and while the sticks worked as intended, I noticed they went bad after a few months. Just a heads up that they might not last if you're not testing frequently."

"At first, I thought it wasn't working or that I wasn't in ketosis. Then I realized I needed to test in the afternoons, and that's when it registered for me. Also, I pay attention to expiration dates after opening the bottle, as they stop working after that date."

"I started the keto diet on the 1st, and by the 6th day, I was already at the max on the readout. The product arrived quickly, and the expiration date is over two years away. I find it easy to use—just pee in a cup, dip the strip, and compare the color after 40 seconds. I definitely recommend this product!"

"I do intermittent and prolonged fasting while on a low-carb diet. These strips help me track my progress. I compare them with Walgreens brand, and they give identical results. The first picture was taken on the 3rd day of my water fast, and the second was on the 5th day."

"I've tried various Keto strips, but these are by far the best! The small zip seal packs make them incredibly portable, allowing me to keep some in my purse and at home without worrying about moisture damage. Plus, the accuracy of these strips has been a great motivator during my 90-pound weight loss journey."

"As someone practicing intermittent fasting, I was eager to see if I was achieving ketosis. On my 17th hour of fasting, I tested with these strips. After following the instructions, there was barely a color change. I was a bit disappointed, but at least I no longer have to guess. I plan to keep using them to see if I can eventually reach ketosis from fasting alone."

"I absolutely love these strips! The fact that they come in small packages means I won’t ruin a ton if one pack is left open. They are perfect for anyone venturing into low-carb diets like Keto or Carnivore. When I run out, I intend to buy these again!"

"I find the product works well, though I think the price is a bit high compared to others. I suggest not measuring every day and would appreciate a slightly lower price."

"As a type two diabetic following a ketogenic diet, I’ve become fat adapted, and this meter is no more challenging than a blood glucose meter. I appreciate how it requires a chip calibrated to the strips, but the test strips are pricier. I won’t test often—just when I’ve had a good fast—but the meter works very well for my needs."

"These strips are fantastic and easy to use with the monitor! If I ever need more, I would definitely purchase them again!"
