Grasping “Bio Age Testing” Through Bryan Johnson’s Experience

The billionaire Bryan Johnson, featured in the Netflix documentary Don’t Die, is on a quest to attain the lowest achievable “biological age,” or bio age.

He reportedly allocates millions each year towards anti-aging treatments, including a daily regimen of numerous supplements, weekly skin acid peels, collagen-enhancing injections, hyperbaric oxygen therapy, and plasma infusions sourced from his 17-year-old son.

To track his advancement, Johnson has undergone several tests to assess his bio age, asserting that these evaluations show he is currently 5.1 years younger than when he embarked on his anti-aging endeavor.

Nonetheless, doubt persists; a New York Times investigation indicates that Johnson’s biological age might have actually risen by 10 years.¹

Regardless, Johnson’s “don’t die” initiative continues to gain traction.

Bio age testing is a frequent topic on well-known podcasts hosted by Peter Attia, Joe Rogan, and Andrew Huberman. A quick search for “bio age testing” uncovers a multitude of ads for mail-order blood or urine testing kits that assert to offer insights into your biological age and rate of aging. With prices becoming more affordable, you may wonder…

Should you or your clients think about bio age testing?

If yes, which test is the most appropriate? Just as crucial, how should you apply the findings?

This article will address:

• Five FREE techniques to assess your overall health and rate of aging from home
• Doctor-endorsed bio age tests you might have already taken without realizing it
• The science behind commercial bio age tests and their significance
• The two most frequent errors individuals make in their quest for health and longevity

What is Your Bio Age?

Your biological age (bio age) signifies the function of your cells. It does not necessarily equate to your chronological age, which merely counts how many years you have aged.

For example, think about Chang, a 50-year-old man who maintains a sedentary lifestyle, eats unhealthy foods, and smokes. Conversely, Jabari, another 50-year-old, exercises consistently, follows a healthy diet, and practices mindfulness. Setting genetics aside, it is reasonable to conclude that Jabari’s bio age is less than Chang’s.

How Are Bio Age Tests Administered?

Bio age testing kits evaluate one or multiple biological markers of aging, referred to as biomarkers.

Certain tests concentrate on the length of telomeres, the protective caps on chromosomes, while others examine DNA methylation, a process that chemically alters DNA.

After isolating and assessing these markers from your blood or urine, companies utilize the data to determine your bio age.

If you regularly consult a physician, you may already be monitoring some aging biomarkers, such as blood pressure, cholesterol levels, and blood glucose, which can indicate your vulnerability to cardiovascular diseases, a primary cause of premature death.

Why Perform Biomarker Testing?

Biomarker testing facilitates proactive health supervision rather than waiting until illness symptoms present themselves.

For some individuals, it can act as a source of motivation. Learning that your bone health is comparable to that of someone considerably older may drive you to start a routine of strength training.

Moreover, biomarkers furnish objective data, allowing you to quantitatively evaluate various health-related activities. For example, tracking your blood pressure could reveal that regular exercise is beneficial for you, while an energy drink in the afternoon is not.

You don’t need to be affluent to keep track of your aging biomarkers.

This section showcases several underestimated, scientifically validated tests that can offer insights into your bio age—at no expense.

Prior to the advent of advanced blood-based bio age tests, researchers relied on these free tests to evaluate aging rates in their study participants.

IBS Patients Would Exchange Years of Life for a Remedy

A survey of nearly 2,000 people living with irritable bowel syndrome (IBS) showed that a significant number would readily forfeit 10 to 15 years of their life expectancy for an instant cure for their ailment.¹

In a separate study, IBS sufferers expressed their willingness to take a medication with a one percent chance of sudden death if it could ease their symptoms², which may involve urgent diarrhea, gas, or chronic constipation.

Some individuals with IBS report abdominal discomfort that they insist is more severe than childbirth. These incidents can impair concentration, disturb sleep, and reduce workplace productivity.³

As a result, numerous individuals with IBS plan their lives around the availability of clean, private restrooms. The anxiety of unanticipated flare-ups often drives them to steer clear of dining out, social events, or exercising in public.

This pervasive worry is known as gastrointestinal-specific anxiety, affecting aspects from social interactions to overall well-being. It is also a major reason why those with IBS report a diminished quality of life compared to people with other chronic conditions, such as heart disease, diabetes, and late-stage kidney disease.⁴

Managing IBS: Options for You or Your Clients

PN Super Coach Sarah Maughan, certified by Monash University—a pioneer in understanding food sensitivities and IBS—has witnessed how lifestyle changes can help prevent flare-ups, decrease GI anxiety, and allow IBS patients to live satisfying lives.

“I hope everyone suffering from IBS understands they have choices, whether that means consulting a doctor for medication or collaborating with a health coach to discover lifestyle adjustments and how to apply them,” Maughan remarks.

This article will offer more insights from Maughan, covering:

• Understanding IBS: its nature, causes, and various presentations
• What your stool indicates about your digestive wellness
• Five evidence-based lifestyle modifications that can ease IBS symptoms
• The optimal techniques to identify food triggers for IBS symptoms (along with foods that are typically safe)

Furthermore, health coaches will learn how to support clients dealing with IBS while staying within their professional limits.

Understanding IBS

Commonly referred to as “spastic colon,” IBS is the most commonly diagnosed digestive disorder worldwide, impacting around 14 percent of adults.⁵

Unlike Crohn’s disease and other forms of inflammatory bowel disease (IBD), IBS does not alter the gut’s structure. Diagnostic imaging usually reveals no infections, inflammation, or damage to the bowel lining.

This lack of visible illness led many healthcare providers to historically perceive IBS as a psychological concern. However, recent viewpoints have shifted.

Experts now categorize IBS as a functional neuro-gastrointestinal disorder.

This classification signifies that the interaction between the GI tract and the brain is not functioning properly, resulting in unnecessary pain signals and disrupted bowel activity.

Symptoms of IBS

Symptoms of IBS can vary, with some individuals enjoying extended periods of relief before experiencing severe flare-ups that can last from hours to weeks.

Not all IBS sufferers display identical symptoms, complicating the diagnosis.

The illustration below shows the range of IBS symptoms.

Causes of IBS

Researchers are actively investigating the reasons behind the variation in gut function among individuals with IBS, proposing multiple theories.

One theory posits that nerve endings in the GI tract may be excessively sensitive in those with IBS. This heightened sensitivity can give rise to two distinct patterns of symptoms.

Hypersensitive nerves send pain signals to the brain, causing those with IBS to sense digestive actions that others may overlook. For instance, minor gas bubbles can lead to substantial discomfort for someone with IBS, while a person without the disorder might not feel any effect.

Overactive nerves can trigger GI muscles to contract too vigorously, leading to gas, bloating, and diarrhea. Conversely, if they underperform, the muscles may not contract adequately, slowing food transit and resulting in constipation.

Another theory links disturbances to the gut microbiome, which may clarify why some individuals manifest IBS symptoms after a severe GI illness, such as Norovirus.
