Buffer the burn, inside and out.

What's in the bundle: 3 x Mango BICARRB (in your chosen portion size), 4 x ITC Shot and 1 x FLYCARB Beta-Alanine pouch.

ITC Shot: Research has shown broccoli-derived isothiocyanates reduced  blood lactate by 22% at the same workload.

Beta-Alanine: buffer within the muscle. Taken daily over several weeks, beta-alanine increases muscle carnosine, helping buffer the acidity that builds inside the muscle during hard efforts. Research has demonstrated average gains of 2.7%! 

BICARRB: back it up in the blood. Sodium bicarbonate increases buffering capacity outside the muscle, helping neutralise the acidic hydrogen ions in the blood. Bicarb has been shown to lead to gains of up to 3%.

Load Beta-Alanine every day for 6 to 10 weeks, then take BICARRB and ITC Shot before your key races.

Choose your BICARRB portion size (12g, 16g, 20g or 24g) to match your body weight.

Inside and out buffering

Three Products. Two buffers. One burn.

When you push hard, your muscles produce acid faster than they can clear it. That is the burn, and it is one factor that causes you to slow down.

To get to the finish line faster, it helps to reduce the production of the acid, and to buffer any acid produced. Your body can buffer in two places: inside the muscle cell and in the blood around it. Beta-Alanine supports the first and sodium bicarbonate helps the second. Together they give you buffering power inside and out.

Intracellular · Inside the muscle

Beta-Alanine

Helps increase carnosine inside the muscle

Beta-Alanine is the building block of carnosine, a buffer stored inside your muscle cells. Taken daily, it helps raise carnosine levels so acid is neutralised right where it is produced, during surges, sprints and finishes.

It is a slow build, not a quick hit: the benefit comes from consistent daily use over several weeks.

  • Builds over6 to 10 weeks

Extracellular · In the blood

Mango BICARRB

Raises bicarbonate in the blood

Bicarbonate is your main buffer outside the muscle. A pre-session dose of BICARRB raises blood bicarbonate, helping draw buffer the acid that builds up in hard efforts, so you can hold on for longer.

Bicarbonate has been shown to improve performance by up to 3%. Our energy mix makes it easier on the stomach.

Training and racing

ITC Shot

Isothiocyanates from broccoli sprouts

Each shot contains a high dose of bioavailable isothiocyanates (ITCs) extracted from broccoli sprouts. Emerging research suggests that ITCs may help athletes sustain high-intensity efforts and recover more effectively between hard sessions.

How they work together

Because they work in different places and on different timescales, the three products complement each other rather than overlap. Both bicarb and beta-alanine are among the five supplements the IOC recognises as performance enhancing, and research is emerging around ITCs.

  1. Load Beta-Alanine

    Take 4g of Beta-Alanine every day, training day or not. Load for 6 to 10 weeks to build up your muscle carnosine levels.

  2. Test BICARRB & Use ITC Shot in key sessions

    Try your BICARRB before your hardest training sessions to get used to the protocol. Use ITC Shot 3hrs before hard training sessions to stack performance gains over a block.

  3. Use BICARRB and ITC Shot on race day

    Take ITC Shot 3 hours before, and BICARRB 2 hours before your race. Repeat the routine you tested in training.

Frequently Asked Questions for Buffer the Burn

Buffer the Burn FAQ

What's in the bundle?

  • 3 x Mango BICARRB in your chosen portion size (12g, 16g, 20g or 24g)
  • 4 x ITC Shot
  • 1 x FLYCARB Beta-Alanine pouch

Bought separately these cost £43.97. The bundle is £34.99, saving you £8.98.

Which BICARRB portion size should I choose?

Your portion size depends on your body weight and whether you have used bicarb before. Use the What's my portion size? button at the top of this page to find yours. If you are new to bicarb, start with the smaller recommended portion.

Can I take ITC Shot, Beta-Alanine and BICARRB on the same day?

Yes. The three products can all be taken on the same day.

When do I take the ITC Shots?

Take one ITC Shot three hours before hard training sessions and races. Emerging research suggests that ITCs may help athletes sustain high-intensity efforts and recover more effectively between hard sessions.

What are the ingredients?

Mango BICARRB: Maltodextrin, Fructose, Xanthan Gum, Sodium Bicarbonate, Flavourings, Acacia, Lutein Colouring.

ITC Shot: Fructose, Lemon Flavouring, Xanthan Gum, Standardised Broccoli Seed Extract.

FLYCARB Beta-Alanine: Beta Alanine.

What is the tingling from Beta-Alanine?

Beta-Alanine can cause a tingling, usually in the face, neck or hands, that fades within 60 to 90 minutes. If you find it uncomfortable, split your daily dose into smaller servings through the day. This is a common side-effect and not harmful.
