Want More Insights Into Your Longevity? Try One Of The Best Biological Age Tests

Biological age is a measurement of the physiological function of your cells. Why is biological age important you may ask? It's an indication of the lifestyle choices you make each day.

For example, people who smoke tend to have a higher biological age1 than those who don't.

By investing in the best biological age test, you can reveal detailed insights into the habits that impact your overall health and longevity.

"A biological age test uses biomarkers to assess biological age. There are many ways to estimate biological age—such as by tracking movement or measuring clinical markers in blood," Cuellar explains.

This Viome at-home test evaluates DNA health, mitochondrial health, and immune stress, which help quantify the biological factors that are influencing aging at the molecular level.

The data is gathered from testing your gut microbiome and blood transcriptome, which is a human gene expression test that decodes how your cells are functioning.

The actionable report includes 30 scores and subscores that are related to your cellular function, microbiome health, and biological age.

With this test, you'll also gain insight into your energy level, stress response, and immune health. The report includes a list of foods that you should eat and those you should avoid based on your microbiome and blood results, which the company calls precision nutrition.

Tally uses a cheek swap to analyze your DNA and calculate your biological age. The test measures many aspects of your health and provides information on how your body is aging on a cellular level. 

Because aging has so much to do with lifestyle choices, Tally provides actionable recommendations to lower your biological age. These recommendations are personalized to you, based on the results of your cheek swab.

Each TruDiagnostics test kit comes with detailed instructions about how to collect the blood sample necessary for biological age testing.

In the lab, TruDiagnostic measures over one million DNA locations that are known to have significance to health and wellness.

All testing is performed at an in-house laboratory and users receive an over 30 page report with information about the factors that influence their biological age based on their genetics.

Using epigenetic testing, the Elysium Index measures 10 areas of aging. Users receive information about their biological age, cumulative rate of aging, system scores of how nine body systems rank in biological age, as well as evidence-based and science-backed recommendations for healthier habits and longer life.

Epigenetic patterns are analyzed using a computational approach which was developed in Partnership with Morgan Levine Ph.D. from Yale University, a leading epigenetics researcher.

InsideTracker offers users data-driven recommendations based on blood analysis of 17 biomarkers in men and 13 in women.

Using an algorithm, the report gives users a calculation of their biological age and personalized information on how to impact and optimize these biomarkers using exercise, lifestyle changes, nutrition, and supplements.

The brand says these biomarkers were objectively identified, referencing tens of thousands of data samples, which is why there are separate age-related markers for men and women, based on biological sex.

For example, the data showed a significant correlation between C-reactive protein and age for males but not for females, so this biomarker is only evaluated in men.

The purpose of an NAD test is to highlight your blood NAD levels, which are correlated with biological age. When you're taking NAD supplements, it's hard to know how much your body is absorbing and what's being used.

Renue’s home kit tests biological markers to determine whether your supplement is doing what it's meant to. Users collect just a few drops on the test strip and receive results in seven to 10 days.

NAD supports repair and anti-aging processes at the cellular level. It is also a measurement of metabolic health, which can indicate your potential for metabolic syndrome.

This test measures glycan sugar molecules, which are an indication of the level of inflammation in your immune system. This inflammation is influenced by exposure to environmental toxins, lifestyle choices, and your genetic makeup.

Unlike other testing, GlycanAge reviews the inflammatory process at many levels.

The test evaluates how your glycan's functionally affects aging, based on studies that show accelerated glycan aging is associated with some disease development and can be altered by changing lifestyle choices.

With the option to purchase two tests at once, the first is meant to provide a baseline measurement and the second can be done after lifestyle changes have been implemented.

There are a variety of biological age tests on the market. Our process for choosing the best ones involved meticulous examination to ensure that the tests we chose provide a trustworthy indication of biological age based on robust scientific principles and user experiences.

Biological age is sometimes called physiological age since it's a measurement of how your body functions in relationship to your chronological age.

Steve Horvath, Ph.D., Sc.D., from the University of California, discovered the epigenetic clock that measures the age of human tissue far beyond the length of genetic telomeres.

Using epigenetic measurements, scientists found there are several lifestyle factors that affect biological age. They discovered that by changing these factors, a person can significantly improve their average life expectancy.

Cuellar elaborates on the importance of prioritizing lifestyle choices that have a significant impact on longevity. "We now know that a number of factors indeed impact how people age and that what has the greatest impact on one person may be different for someone else," she says.

Biological age testing helps provide immediate feedback on certain lifestyle habits. Testing can indicate the potential for a disease before symptoms appear and help you develop a personalized approach to improve your health and well-being.

To maximize longevity using a biological age test, you must start with a baseline. Baseline measurements give you an indication of your current health and wellness status so you can take appropriate measures to improve your health.

However, taking a series of tests over months or years has limited value unless you are committed to making changes in your lifestyle choices.

Studies have shown that a novel aging measure based on clinical biomarkers, also called a phenotypic age, could predict biological age2. There are several ways to measure your body's biological age.

It's a fact of life that some people live longer, while others have an early onset of chronic illnesses or seem to age more quickly. Using the best biological age tests at home, you can unlock your health potential and identify the factors that speed up your biological age.

"You cannot optimize what you can't measure," Cuellar says. "You wouldn't drive a car without a dashboard, yet we do that with our bodies. It's very important to measure your health periodically to see if the changes that you make in your lifestyle work for you."

Biological age tests should be done every six months as you are making lifestyle changes. This helps you determine if the changes are making a difference in your health.

The best biological age tests are easy to take, accurate, affordable, and produce information you can use.

"Biological age tests are most impactful for health and longevity when not only do users have important health information at their disposal, but they have accompanying action plans to lower their biological age and increase their health span," Cuellar says.

The best biological age tests can help motivate and inspire you to make healthy lifestyle choices that reduce your risk of disease and lengthen your life—but the test is just the tip of the iceberg.
