Panax ginseng is popping up in more and more products for athletes. The question is: where does the marketing end and the science begin? I am cutting through it. What follows is what the evidence says, and just as importantly, what it does not say. Do you want the full picture on fueling on the bike first? Then read my complete guide on energy bars and cycling.

What is Panax ginseng and why does it interest athletes?

Panax ginseng, also called Korean or Asian ginseng, is a plant from Korea, China, and Russia. The active substances are called ginsenosides. More than a hundred have been identified in the root. In research on the human body, Rb1, Rg1, and Re receive the most attention.

Interest from the sports world is not new. As early as the eighties and nineties, Eastern European athletes used adaptogenic herbs in their training programs. An adaptogen is a plant whose active substances are being studied for their influence on the body. An important difference from, for example, caffeine: ginseng does not act as a stimulant. There is no direct, palpable kick. The substances are studied for a slower, chronic effect.

For cyclists, mountain bikers, runners, and triathletes who spend hours in the red zone, that sounds relevant. But relevance begins with evidence. And that is where it gets nuanced.

What does the evidence say about Panax ginseng and athletic performance?

The honest answer: there is evidence, but it is not conclusive. Several studies in humans have looked at ginseng and endurance, fatigue, and recovery. The results are mixed. Positive signals in one study, no measurable effect in another.

The largest review article in this field, Bahrke and colleagues from 2009, examined published studies on ginseng and performance and drew a clear conclusion: despite better research methods, the same weaknesses kept recurring, and a performance gain in well-designed studies has yet to be demonstrated. That is the sober state of affairs.

What often recurs as a limitation in this research:

• Most studies use small groups, often fewer than fifty participants. As a result, a real effect is statistically difficult to prove.
• Dosage, extraction method, ginsenoside profile, and duration of supplementation vary significantly. Comparing studies with one another becomes difficult.
• There is no approved EFSA health claim for Panax ginseng and athletic performance. I therefore communicate ginseng as an ingredient whose effects are being researched. Not as a proven performance gain.

Conclusion from the field: interesting, being researched, not yet proven. That is the honest summary. No overclaiming, no underclaiming.

How does Panax ginseng relate to other adaptogens?

In the world of functional ingredients for athletes, three adaptogens are central: Panax ginseng, Rhodiola rosea, and Ashwagandha. Each contains different active substances that are being studied.

I work with Panax ginseng and Rhodiola rosea as ingredients in specific bar variants. I communicate both as ingredients whose effects are being researched, in line with current EU regulations. No promises, just honest context.

Why carbohydrates remain the foundation, even with functional ingredients

Functional ingredients like ginseng are fascinating. But they do not replace fuel. That is a principle I do not deviate from. What drives you yourself during exercise are carbohydrates.

During exercise of more than sixty minutes, a trained athlete uses about 60 to 90 grams of carbohydrates per hour. There is a limit to how much glucose your intestine can absorb per hour, about 60 grams, via a primary transport channel. If you combine glucose with fructose, your body uses a second, separate transport channel and the total absorption rises toward 90 grams per hour. That is the principle behind the 2:1 glucose/fructose ratio that I incorporate into every fruit performance bar. Research by Currell and Jeukendrup shows that this combination lifts absorption and effective performance higher than glucose alone.

This is what a realistic distribution looks like in practice:

• Sports drink with 6 to 8 percent carbs, 500 to 800 ml per hour, good for 30 to 60 grams of carbohydrates. That is your main source and your hydration in one.
• 1 to 2 Eagle fruit performance bars per hour, 20 grams of carbs per 25-gram bar. Solid food that keeps your stomach calm and prevents flavor fatigue.
• In the finale, during high intensity, possibly a gel for a quick peak.

Together, you reach that 60 to 90 grams per hour comfortably, without overloading your stomach. Do you want to know when it is best to take a bar and when a gel? You can read that in my article on energy bar versus energy gel. Ginseng is included as an ingredient in a specific variant and works more slowly, over weeks. Carbohydrates provide the fuel during the ride itself. Both have a place. They do not replace each other.

Is Panax ginseng safe for athletes?

Panax ginseng has a widely studied safety profile for standardized extracts in doses of 100 to 400 mg per day, over periods of up to twelve weeks. The World Anti-Doping Agency (WADA) does not have Panax ginseng on the prohibited list. Athletes who fall under WADA control can in principle use ginseng without a doping risk, provided the product comes from a reliable source with decent quality control.

I produce the fruit performance bar at a certified Belgian production company (BRCGS Food Safety, ACS), without artificials, vegan, gluten-free, and lactose-free. The production complies with European food legislation. Ingredients such as ginseng are included in amounts that fit within the researched dosage range.

One precaution: Panax ginseng can affect the action of blood thinners like warfarin. If you use medication, consult your doctor or sports dietitian first.

Why I choose transparency over hype

The supplement industry likes to sell adaptogens as proven performance boosters. I do not do that, for the simple reason that it is not correct. Panax ginseng is an ingredient whose effects are being researched. That is an honest position.

My fruit performance bar is primarily fuel. Clean, functional, during exercise. The 2:1 carbs are the core. Ginseng is in it as an ingredient in a specific variant. That reflects exactly what the evidence currently supports and nothing more than that.

Athletes deserve that honesty. You ride 180 km in the rain. You run your marathon at 4 a.m. You train while others are asleep. You do not need hype. You need fuel and clear information. Read here why more and more cyclists are trading the gel for a clean-label bar. No gel. No brick. Fuel during exercise. Fuel your flight.
