There are so many ketone meters to buy it’s hard to know which ones are best. We selected 8 of the best ketone meters market to make your search easier.

Being in ketosis is important on the keto diet. In fact, everyone on keto desperately wants to raise their ketones to reach this metabolic state. Many even hope to remain in it until they’ve reached their goals and ideally longer.

But how do you know if you’re in ketosis? One surefire way is by using ketone meters. There are two types of ketone meters to buy on the market: blood ketone meters and ketone breath analyzers. The devices measure blood ketone levels or ketones on your breath. Both are highly accurate (especially the blood meters), and some brands can measure additional metrics: blood glucose, hemoglobin, and more.

Ketone meters have an edge over ketone test strips. The latter can accurately measure ketone levels while you’re in the initial stages of ketosis. But when you’ve become keto-adapted after following keto for weeks, their accuracy diminishes. That’s why if your goal is to stay in ketosis for a really long time — ketone meters are better for gauging ketosis.

So, which ketone meters to buy in 2021? Here is a quick rundown of the best ketone meters on the market.
