The Everlywell Metabolism Test measures hormone levels in blood and saliva. Cortisol, free testosterone, and thyroid-stimulating hormone (TSH) help regulate the body’s metabolism rate. This rate, in turn, may affect a person’s weight and energy levels.

Below, we describe Everlywell’s metabolism test and the hormones it measures. We also compare it to similar tests from some of the company’s competitors.

Metabolism is the process of breaking down nutrients into energy.

A person’s metabolic rate, the rate at which this happens, depends on several factors, including:

  • age
  • gender
  • muscle-to-fat ratio
  • levels of exercise
  • hormone function

Everlywell says that its metabolism test can indicate whether a person has a slower, normal, or faster metabolism. The test analyzes three hormones — cortisol, free testosterone, and TSH — that play a role in regulating metabolism.

The company states that each test is reviewed by an independent physician who is board certified in the customer’s state of residence.

To use this test, a person:

  1. purchases the kit online
  2. registers the kit when it arrives
  3. collects a finger prick blood sample and a saliva sample using the tools in the kit
  4. mails the samples to a certified laboratory using the prepaid shipping container provided

Within days of receiving the samples, Everlywell notifies the person that their test results are available. The person logs into the company’s secure platform to view their results and personalized recommendations.

Everlywell uses laboratories certified by the Clinical Laboratory Improvement Amendments, which means that these labs are subject to state and federal certifications and inspections.

The company also states that it complies with the Health Insurance Portability and Accountability Act (HIPAA) and encrypts people’s personal information.

The EverlyWell Metabolism Test measures cortisol, free testosterone, and TSH levels.


Cortisol is a hormone that the adrenal gland makes and releases into the bloodstream. Many cells have cortisol receptors, and this hormone has various effects on the body.

Cortisol helps control blood sugar, for example, which affects a person’s metabolism.

Free testosterone

Testosterone is a hormone present in everyone. The gonads in the body produce it, and it affects muscle mass and body fat composition.

The pituitary gland produces and releases TSH into the body. This hormone controls the production of two other thyroid hormones, thyroxine and triiodothyronine.

These two hormones have many roles, including maintaining metabolic rate, heart and digestive functions, and brain development.

At the time of publishing, the EverlyWell Metabolism Test cost $49.

The company also offers a subscription service, in which a person selects one of 14 tests each month for $24.99.

Everlywell accepts payment from Health Savings Accounts and Flexible Savings Accounts, among other methods. It offers free shipping.

A person’s test results may indicate whether they have lower, higher, or average levels of the three hormones that this test analyzes.

The company hosts live group webinars to discuss next steps with a healthcare professional and others who have taken the test.

However, keep in mind that these test results do not represent a diagnosis. If they indicate an excess or deficiency of certain hormones, contact a healthcare professional for further tests and treatment.


Having too much cortisol may lead to Cushing’s syndrome. This can have various effects, such as glucose intolerance, high blood sugar, high blood pressure, and rapid weight gain in the face, chest, and torso. It may result from the use of oral, injected, inhaled, or topical steroid treatments for other health issues.

Additionally, having too much cortisol may lead to low libido. And females with too much cortisol may experience fewer or irregular periods or stop menstruating.

Having too little cortisol may also be a sign of Addison’s disease. Some symptoms of this condition include gradual, unintentional weight loss and muscle weakness.

Free testosterone

Low levels of testosterone may lead to weight gain and higher cholesterol levels.

It is uncommon for adult males to produce too much testosterone. Females who produce an excess of this hormone may have polycystic ovary syndrome, which can lead to an increase in acne, body hair, and muscle mass.

Having too little testosterone can lead to an increase in body fat, a loss of muscle tone, fatigue, and a low sex drive. In males, it can cause erectile dysfunction.


Having too much TSH may indicate hypothyroidism. This condition can cause symptoms such as weight gain, depression, tiredness, sensitivity to cold, muscle weakness, dry skin, brittle hair and nails, and irregular periods.

Having too little TSH may indicate hyperthyroidism. People with this condition may experience unintentional weight loss, excessive hunger, restlessness, insomnia, diarrhea, intolerance to heat, palpitations, and anxiety, among other symptoms.

Before purchasing an Everlywell Metabolism Test, a person may wish to consider these possible benefits and downsides:

At the time of publishing, Everlywell did not hold accreditation with the Better Business Bureau (BBB). The BBB gives the company an A+ grade. However, the average customer rating is 1.1 out of 5 stars. On Trustpilot, customers give Everlywell an average rating of 2.4 out of 5 stars.

Positive reviews indicate that taking an at-home test was more convenient than booking a test through a doctor. One customer reported that the company’s customer service team was responsive when a test kit had defective parts.

Negative reviews say that Everlywell took up to several weeks to process tests. One customer reported that the company’s results differed significantly from results that they received from other labs.

Several customers mentioned that a person can only contact Everlywell through an online form and cannot speak to a representative.

The Everlywell Metabolism Test measures the levels of cortisol, free testosterone, and TSH in a person’s blood and saliva. The results of this analysis may provide an insight into whether the person’s metabolic rate is slow, fast, or within a normal range.

However, at-home metabolism test results are not a diagnosis. If the results indicate higher or lower levels of one or more hormones, contact a healthcare professional for further tests and treatment.
