The Kinetic Gradient Matrix
The Superior Bicarbonate
Sodium bicarbonate is one of the most evidence-backed ergogenic aids in sport. The limit was never the molecule. It was getting the full dose past the stomach without the GI distress that forces athletes to under-dose. Bicarb 3.0 approaches that problem at the level of materials science.

01 / The real problem
Buffering was never the hard part. Delivery was.
During hard efforts, the working muscle accumulates hydrogen ions and pH falls. Ingested sodium bicarbonate raises blood bicarbonate, steepening the gradient that helps move those hydrogen ions out of the muscle and supporting high-intensity performance.
The catch has always been the stomach. Taken as powder or in solution, sodium bicarbonate meets gastric acid and reacts on contact: NaHCO3 + HCl → NaCl + H2O + CO2. That reaction can produce gas, bloating, cramping, and other gastrointestinal discomfort. Every gram that reacts in the stomach is also a gram that does not reach the intestine intact.
The delivery challenge is simple: move the intended dose through the stomach intact and release it where it can be absorbed.
02 / The current benchmark
How the Maurten Bicarb System protects the dose
Maurten deserves credit for making bicarbonate practical for a generation of athletes. Based on its published materials and ingredient list, the system uses two primary protective ideas:
A carbohydrate hydrogel coating
A maltodextrin, modified-starch, hydroxypropyl-cellulose, and xanthan-gum matrix physically embeds the bicarbonate and slows acid contact by acting as a diffusion barrier.
Mini-tablet geometry
The bicarbonate is pressed into small tablets intended to move through the stomach efficiently and reduce exposure time to gastric acid.
Both mechanisms are meaningful. Bicarb 3.0 takes a different engineering route by adding a chemically reinforced barrier and a sacrificial mineral layer designed to intercept acid before it reaches the bicarbonate core.
03 / The Bicarb 3.0 architecture
A reinforced matrix with a third line of defense.
Bicarb 3.0 combines a protective matrix and controlled particle geometry, then adds a calcium-carbonate-rich shell intended to defend the payload at the beadlet surface.
Sodium alginate, not xanthan gum
Matrix upgradeXanthan gum is primarily a viscosity modifier. Sodium alginate is a gelling polymer that can crosslink in the presence of divalent calcium to form a three-dimensional gel network.
3 mm spheronized beadlets
Geometry upgradeA sphere presents the least surface area of any shape for a given volume. Uniform beadlets reduce the bicarbonate surface exposed to acid and support consistent gastric transit.
The calcium-alginate egg-box
New mechanismCalcium ions crosslink alginate into a reinforced gel structure. The calcium carbonate also functions as a sacrificial antacid at the beadlet surface.
04 / The mechanism, in detail
The egg-box model, and why it creates a real barrier
Alginate is a natural polymer made from mannuronic acid and guluronic acid. When divalent calcium is introduced, the G-blocks on neighboring alginate chains fold around the calcium ions and lock them into place, forming rigid junction zones. The arrangement resembles eggs seated in a carton, hence the egg-box model.
The result is a crosslinked network rather than a simple surface coating. Calcium carbonate plays two roles: it supplies the calcium that builds the egg-box shell and acts as a sacrificial antacid at the beadlet surface.
05 / The Kinetic Gradient Matrix
The shell is built from the inside out.
Most encapsulation coats a particle from the outside. Bicarb 3.0 is designed so its protective structure self-assembles from within the beadlet during manufacture.
The beadlet ingredients are dry-blended, wetted, and then spheronized at 18,000 RPM. At that speed, centrifugal force sorts components by density: calcium carbonate migrates toward the beadlet surface while the lighter bicarbonate remains concentrated toward the center. The motion creates a density gradient through the beadlet, which is why we call it a Kinetic Gradient Matrix.
The calcium carbonate ends up concentrated where it is intended to be most useful: at the outer surface, first in line to meet stomach acid, while the bicarbonate payload remains protected at the core.
06 / Head to head
Same goal, different engineering
Acid can diffuse through the coating toward the core.
Calcium carbonate is positioned to intercept acid at the shell.

07 / What it means for the athlete
A stronger barrier supports a more usable dose.
The engineering serves one athlete-facing goal: help more of the intended dose survive the stomach so it can reach the intestine intact. Historically, gastrointestinal distress is one of the main reasons athletes under-dose sodium bicarbonate or avoid it entirely.
Bicarb 3.0's thesis: keep what the category gets right, reinforce it with gelling chemistry, and add a calcium-crosslinked, self-organizing shell that turns a passive coating into an engineered barrier.
