Why Do Your Muscles Burn?

The burning sensation you feel in your muscles during intense efforts — whether it’s sprinting, interval training, or
climbing uphill — is the result of your body pushing its limits to supply energy.

Normally, your muscles rely on aerobic metabolism, where oxygen helps break down glucose for energy. This process is efficient and sustainable over long periods.

However, when your body demands more energy than it can produce aerobically — like during short bursts of extreme intensity — it switches to anaerobic metabolism. In this process, your muscles break down glucose without using oxygen, producing lactic acid as a byproduct.

Here’s where the burn comes in: As lactic acid accumulates, it releases hydrogen ions which increase the acidity (lowering the pH) in your muscles. This acidity interrupts muscle function and causes that familiar burning sensation, signaling muscle fatigue.

This burning sensation is most noticeable during high-intensity intervals, sprinting, or when you’re pushing hard above your lactate treshold for 3 to 15 minutes. This is the point where your body can no longer clear lactic acid as quickly as it produces it, leading to muscle fatigue and decreased performance.

How Does Nrgy Unit Drink Buffer Help?

Developed by Dr. Tim Podlogar, the head of science at Nduranz, Nrgy Unit Drink Buffer combines the power of sodium bicarbonate and a perfectly balanced carbohydrate mix to increase your endurance by:

1.) Neutralizing the acid.
As lactic acid builds up and increases muscle acidity, sodium bicarbonate acts as a buffer, neutralizing the excess hydrogen ions.

This slows down the drop in pH, preventing your muscles from becoming too acidic.

2.) Stopping the burn.
Sodium bicarbonate delays muscle fatigue by keeping your muscles in a less acidic state.

With less acid accumulating in your muscles, you can continue performing at a higher intensity for a longer period of time without feeling that burning sensation.

3.) Improving overall endurance.
The added carbohydrates in Nrgy Unit Drink Buffer helps you delay your glycogen consumption so you have more energy for sustained efforts. Paired with sodium bicarbonate, this combination allows you to push harder for longer.

Lemon taste

The taste is too strong. The consistency is with some kind of admixture and
seems like a long time.
