Your metabolism is a vital part of your overall health. It affects how you burn calories, store energy, and feel on a day-to-day basis.

If you’ve been feeling like something is a little “off” recently, it could potentially be related to your metabolism. For those who are interested in checking in on their gut, Everlywell makes one of the most popular metabolism tests around.

We did a little research to help you decide whether this test is right for you.

During the metabolic process, your body combines the calories from the things you eat and drink with oxygen to release energy. This is what keeps your body fueled.

When your metabolism isn’t working the way it should, the entire bodily system can get thrown off. A slow metabolism can lead to:

A metabolic test can help you find out how and maybe even why your metabolism isn’t functioning properly.

Everlywell provides a wide range of at-home medical testing kits to help you stay on top of your health from the comfort of your home.

One of the most popular tests is the metabolism test, which works by measuring three hormones that are closely linked to normal metabolic function. These hormones are:

By measuring cortisol, testosterone, and TSH, the test can give you some key insights into your metabolic health.

Plus, becoming familiar with these hormone levels can help you learn more about other related health issues you may be experiencing.

Each test is reviewed by a physician and the overall process is regulated by Clinical Laboratory Improvement Amendments (CLIA) to ensure quality laboratory testing. The process is also compliant with the Health Insurance Portability and Accountability Act (HIPAA).

While the test isn’t covered by insurance, you can use a Flexible Savings Account (FSA) or Health Savings Account (HSA) to pay for it if you have one.


Cortisol helps control glucose levels. (Glucose provides the body with energy.) Cortisol is also released when people experience stress and the fight, flight, or freeze response.

As a 2007 study noted, low levels of cortisol cause a decrease in energy, increased TSH levels, and increased insulin sensitivity.

When cortisol levels are low, the body can have a hard time metabolizing food into fuel, making it difficult to perform exercises or even day-to-day tasks.


Testosterone is another crucial hormone for a healthy metabolism.

Low levels of testosterone can cause weight gain, especially in men. A long-term testosterone deficiency can even lead to a risk of diabetes in men.

Thyroid-Stimulating Hormone (TSH)

The thyroid gland produces thyroid hormone (TH), while TSH regulates production of TH.

TH is an important hormone for healthy metabolic processes. Too much TH can lead to a hypermetabolic state that includes energy loss, weight loss, and low cholesterol.

On the other hand, a TH deficiency can lead to weight gain and high cholesterol.

The Everlywell metabolism test gives you a full TSH assessment to determine if your TSH levels are in the healthy range.

The Everlywell metabolism test promises to be easy to take at home. Here’s what the process looks like:

  1. After placing your order, you’ll receive a kit in the mail that includes instructions, materials, and pre-paid shipping.
  2. You’ll need to register for an account on the Everlywell website, where you’ll be notified of your results later.
  3. You’ll take a saliva test and finger prick test per the provided instructions.
  4. Once you complete the tests, you’ll package up your samples in the provided biohazard bag.
  5. Use the prepaid label to ship your samples off to the lab.
  6. Within a few days, you’ll receive physician reviewed digital results broken down by hormone.

Best forgeneral knowledge about hormones related to metabolismpeople who want a free consultation after their at-home testpeople who want a more extensive hormone assessment for other potential causes of weight gainfor people worried about liver function, this metabolic test can give you a more extensive understanding of your glucose levels

Compared with top competitors, the Everlywell metabolism test is low-cost, convenient, and reliable.

For people who are looking for general insight into how their hormones may be affecting their metabolism efficiency, this test is a great option.

For those who are interested in more extensive hormone analysis or who are concerned about liver function, this test isn’t the best choice.

Understanding and staying on top of your metabolic health can help you to feel your best on a day-to-day basis.

Plus, it’s also important for maintaining overall wellness and preventing the development of more serious conditions, like diabetes.

Taking a convenient and affordable Everlywell metabolism test can help you better understand how your metabolic system is working, but it should never replace diagnosis and treatment by a licensed medical professional.

However, your results can give you lab-certified data to share with your doctor to help get your metabolism function back on track.
