about this product.

The Maurten Bicarb System is a sodium bicarbonate supplement designed for use before high-intensity exercise. Sodium bicarbonate is a well-studied alkalising agent that works by raising blood pH, which helps buffer the build-up of hydrogen ions during intense effort. That buffering effect is associated with a delay in the onset of muscular fatigue — particularly relevant in events or training sessions where you are working at or near threshold for sustained periods.

The product is aimed at competitive and serious recreational athletes: track and road cyclists, middle- and long-distance runners, rowers, and anyone whose performance is limited by the accumulation of metabolic acid during repeated hard efforts. It is most relevant in training blocks where intensity is high and recovery between sessions is short.

Sodium bicarbonate supplementation is one of the more consistently supported ergogenic strategies in sports science. The challenge with it has historically been gastrointestinal discomfort — a well-known side effect when taken in standard bolus doses. Maurten's Bicarb System addresses this with a specifically developed delivery format designed to reduce that GI burden, which is the key differentiator from simply purchasing sodium bicarbonate in bulk.

This is not an everyday supplement. It is a targeted, session-specific tool for athletes who have already optimised the basics and want a protocol-driven edge on race day or in key training sessions.

Follow the protocol on the packaging — timing and preparation before exercise is specific to this system and matters for both efficacy and tolerability. Do not substitute a generic sodium bicarbonate dose; the format here is designed to manage gastrointestinal side effects.

frequently asked.

How is this different from just taking sodium bicarbonate powder?

Standard sodium bicarbonate taken as a bolus is well known for causing nausea, bloating, and gastrointestinal distress in many athletes. Maurten's Bicarb System uses a specific delivery format designed to reduce that GI burden — which is the primary reason to choose this over a generic source.

Who is this most relevant for?

Athletes competing or training at high intensities where metabolic acid accumulation limits performance — middle-distance runners, cyclists, rowers, and team sport athletes during repeated sprint efforts. It is less relevant for low-intensity or purely aerobic training.

When should I take it before exercise?

The timing is protocol-specific. Follow the instructions on the packaging exactly — the system is designed around a particular preparation window, and deviating from it may affect both efficacy and tolerability.

Are there any safety considerations I should know about?

Sodium bicarbonate may not be appropriate for individuals with kidney conditions, those on a sodium-restricted diet, or people taking certain medications. If you have any of these concerns, check with a clinician before use.

Should I test this in training before using it on race day?

Yes — this is standard practice with any new supplement protocol. Trialling the system in a hard training session first lets you assess your individual tolerability before relying on it in competition.

The first adrenal support that made a quick difference.

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

MRVerified Buyer

Steadier mornings within a fortnight.

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

ALVerified Buyer

Subtle, but real.

2 weeks ago

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

SKVerified Buyer

My clinician recommended it.

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

TPVerified Buyer

Recovery feels faster.

1 month ago

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

DVVerified Buyer

Does what it says.

1 month ago

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
