WHY HONEY

THAT’S WHERE HONEY COMES IN.

Honey provides natural glucose, which we combine with a performance dose of electrolytes for rapid hydration and natural energy support.

WHAT YOU LOSE DURING TRAINING

Hard sessions deplete electrolytes and usable energy. If you do not replace the right things in the right amounts, performance drops.

Every hour of intense exercise, the average person can lose approximately:

 
950MG

sodium

Supports fluid absorption - primary electrolyte lost in sweat

200MG

POTASSIUM

Supports fluid balance, nerve signaling, & muscle function

20MG

MAGNESIUM

Keeps the system stable under stress

70MG

GLYCOGEN

Your stored training fuel- average used per hour

Science-backed dose and ratio to help you replenish what you actually deplete during an hour of intense exercise.

We use honey to activate our sodium-glucose co-transporters, supporting faster electrolyte and fluid absorption. Our ratio is inspired by decades of oral hydration science established by the WHO.

DUAL-CARB FUEL

2O3 uses a real fruit base, raw honey, and premium electrolytes to deliver better performance than artificial products or products with processed sugar.

Honey has free acting glucose and fructose, providing both fast-acting and long-lasting energy. They also use different intestinal transporters for absorption which spreads carbohydrate uptake across two pathways limiting GI distress.

BUILT WITH SOME OF THE

STRONGEST ATHLETES in the world

 

203 was founded by a record-holding powerlifter and is being built alongside other world champions.

 

This is not a corporate brand pretending to know hydration. 2O3 was built by people who live the problem.

Nathan Krah - MD, PhD

I use 2O3 because the formulation makes sense to me: it combines physiologically relevant amounts of sodium, potassium, and magnesium with honey as a natural source of glucose and other carbohydrates. As a physician-scientist and endurance athlete, I value products that are thoughtfully formulated around physiology to meet the demands of high performance.

Jon Heck - CSCS, CISSN

Unlike most electrolyte supplements, 2o3 features a unique synergy between sodium, and a sizeable portion of potassium and magnesium in conjunction with raw honey. This combination of electrolytes and honey allows for maximum transport and uptake of the ingredients, providing sustained energy, force output and improved recovery in a pre, intra or post-workout setting. I personally consume a can pre and/or post workout with every training session, and recommend the same for my clients.

FAQS

QUESTIONS BEFORE YOU TRAIN?

I'M NOT A PRO ATHLETE, IS 2O3 FOR ME?

Absolutely! This is for anybody who’s pushing themselves in any form of exercise, not just the pros. Whether it’s a hardcore resistance training session, a swim, hot pilates, or a run, 2o3 is replacing what you lose.

WHEN SHOULD I TAKE 2O3?

Sipping throughout your session is the best way to fuel your momentum, prevent performance dips, and subsequently lower recovery demands. Our electrolyte dosage combined with honey is formulated to be fast acting so you can replenish what you’re depleting, as you’re depleting it. You can also take 2O3 pre or post workout. Taking 2O3 as a pre will help you fill yourself with what you’re about to lose, and taking it post will aid in your recovery.

ISN'T SUGAR BAD FOR ME?

Processed sugars are often best limited, but naturally occurring sugars can play an important role in the right context. Honey provides glucose and fructose, giving the body readily available energy alongside a more sustained source of fuel. When glucose is paired with sodium, it also activates sodium-glucose co-transport in the small intestine - a mechanism that helps the body absorb sodium and water efficiently. That’s why honey isn’t merely a finishing touch in our formula; it’s a functional component designed to help athletes get more from their hydration, training, and performance.

WILL YOU MAKE A SUGAR-FREE VERSION?

We would never hurt the efficacy of our product by removing sugar, 2o3 is the first complete performance hydration system without compromise because of its dosing and source of natural sugar. Removing sugar would slow down the rate of electrolyte absorption by 30-50% and leave you without one of the most premium forms of natural energy. If zero sugar hydration is the way for you, you’re free to browse inferior options. They are plentiful.

ISN'T A LOT OF SALT BAD FOR YOU?

Salt has a negative connotation from boomer medicine the same way carbs do, but this couldn’t be further from the truth. Sodium is essential for everything you do, not just working out. Whether it’s walking, talking, breathing, dancing, or training, you’re using sodium to do it. It’s also the primary solute in sweat by a wide margin. You’re not overloading yourself with sodium if you’re training hard, you’re simply replacing what you’re getting rid of throughout the exertion process. That being said, if you have medical issues like hypertension or kidney dysfunction, we strongly recommend consulting with your doctor before supplementing with any electrolyte product.

WHO IS 2O3 FOR?

2O3 is for anyone who is pushing themselves physically, whether that be chasing world records, playing soccer, doing hot pilates, or fighting fires. 2O3 is based on decades of hydration science to give you the right dose of electrolytes with natural glucose so you can get hydrated and energized as quickly and for as long as possible.
