Kim Kardashian's New Energy Drink

Kim Kardashian has reintroduced her energy drink, Update, as a co-founder, highlighting its unique ingredient: paraxanthine, which replaces traditional caffeine. The 45-year-old entrepreneur asserts that the beverage contains zero calories, no sugar, and no artificial flavors. The inclusion of paraxanthine has piqued the interest of both fans and health professionals. Marketed as a cleaner and smoother alternative to caffeine, paraxanthine is gaining traction on social media and in online searches. But what is paraxanthine, and is it safe for consumption?

Understanding Paraxanthine

What is Paraxanthine?

Paraxanthine is a natural byproduct of caffeine metabolism, processed in the liver alongside theobromine and theophylline. While caffeine is a widely used stimulant found in coffee, tea, and energy drinks, approximately 70% of it is converted into paraxanthine. This compound is also present in small amounts in both green and roasted coffee beans. Unlike caffeine, which stimulates the central nervous system directly, paraxanthine targets specific pathways, promoting alertness and energy without the typical side effects associated with caffeine, such as jitters or rapid heart rates. This has led to its promotion as a next-generation alternative in energy and nootropic drinks.

Comparing Coffee and Paraxanthine

How Do Coffee and Paraxanthine Differ?

Both paraxanthine and caffeine affect adenosine receptors in the brain, which play a role in regulating sleep and alertness. However, paraxanthine may offer additional benefits, such as:

Providing sustained energy

Causing fewer fluctuations in blood pressure

Resulting in less anxiety or overstimulation

Minimizing the risk of an energy crash

Initial research indicates that paraxanthine can enhance cognitive performance, reaction times, and mental clarity without the harsher effects of traditional caffeine. Nonetheless, it is crucial to note that comprehensive long-term studies on humans are still limited.

Safety of Paraxanthine

Is Paraxanthine Safe for Consumption?

Research suggests that paraxanthine is generally safe when consumed in controlled amounts. Since it is naturally produced in the body following caffeine intake, it is considered biologically familiar. However, experts warn that isolated paraxanthine in supplement or beverage forms has not been studied as thoroughly as caffeine. Regulatory agencies are still assessing its widespread use in consumer products. Individuals who are sensitive to stimulants, pregnant, breastfeeding, or have heart conditions should consult a healthcare professional before trying new stimulant-based beverages. Medical professionals advise moderation, as no stimulant is entirely without risk, and long-term research is ongoing.

Zero Sugar Claims in Energy Drinks

What About Zero Sugar Claims?

When energy drinks claim to have zero sugar, they often contain sucralose, a sweetener that has no calories but is approximately 600 times sweeter than sugar. While it is generally considered safe for diabetics in the long term, emerging studies suggest that its effects on insulin may not be as harmless as previously thought. Experts express concerns about its impact on gut health and metabolism, particularly in teenagers whose metabolic systems are still maturing.
