Product Review

Accuracy: 3.5/5

This product tries to analyze ketosis via the breath. It does this via measuring the amount of acetone in the breath. Blood analysis is more accurate but doesn’t measure the actual amount of ketones in the blood either, it measures beta-hydroxybutyrate (BHB).

Price: 3/5

From an upfront perspective, this is the most expensive way to measure ketosis. However, it’s a once off price so you need to consider how often you will measure your level of ketosis. If you are going to be measure once or twice a week for only a few months then you will want to go with a different option.

If you want to measure often or want to measure more than one person, you should consider this product because it is a once off payment and can be used by multiple people (with different mouth pieces).

Ease of use: 4.5/5

The Ketonix breathalyzer is easy to use and easy to read. You will need to apply consistent pressure to get accurate readings which may take a bit of practice. This doesn’t matter thought because it’s completely reusable.

The 4 different colored lights make it very easy to understand.

The software is straight forward and can be used by the most tech-impaired person.

Convenience: 5/5

This is the most convenient option for ketosis testing. It’s portable and can be done anywhere.

Urine testing obviously needs a bathroom and can be a bit of a hassle.

Blood testing can be done in most places but is socially better to do it in private. There are also hygiene complications and you need multiple items to conduct a ketosis blood test properly.
