Original CAFCARB delivers a high dose of bicarbonate and 120 mg of caffeine in one convenient product. Bicarbonate has been shown to improve performance by up to 3% by increasing the body’s buffering capacity, while caffeine enhances alertness, reduces perceived effort, and improves time to exhaustion. Combined, they help you push harder for longer.

Our original unflavoured formula was the world’s first caffeinated bicarbonate product, designed for athletes who want performance without any additional flavour or additives.

Frequently Asked Questions for BICARRB

BICARRB FAQ

Extra Information

What is BICARRB?

BICARRB is a sports nutrition product designed to help athletes perform at their best by increasing the body’s natural buffering capacity. Each serving consists of an Energy Mix, which is designed to ensure the sodium bicarbonate can be easily tolerated, and the Bicarb Mix.

BICARRB has been developed and tested by athletes to support performance in high-intensity endurance events such as running, HYROX, cycling, triathlon, and many other sports.

How It Works

During intense exercise, your muscles produce lactic acid. The build up of the acidic H+ ions contributes to fatigue. Sodium bicarbonate acts as a natural buffer, helping maintain optimal pH balance and delaying the onset of muscle burn. Bicarb has been shown to:

  • Increases time to exhaustion during high-intensity effort
  • Improves repeat sprint ability
  • Helps sustain power output during endurance events

How to Use

We recommend taking BICARRB 90–120 minutes before exercise. Mix the Energy Mix with just 60ml of water then add the Bicarrb Mix and consume immediately.
