What Is Baking Soda?
Baking soda, or sodium bicarbonate, is a naturally occurring compound best known for its use in baking. However, in the athletic world, it serves a very different purpose—as a powerful pH buffer. When taken before high-intensity exercise, baking soda helps combat the build-up of lactic acid in muscles, delaying fatigue and improving overall performance.
This buffering capacity makes it a valuable tool for athletes engaged in anaerobic sports where the accumulation of hydrogen ions (H+) leads to muscle acidosis and reduced output. Baking soda neutralizes these ions, allowing muscles to contract harder and longer before fatigue sets in.
How Does It Boost Performance?
During intense exercise, your muscles rapidly produce lactic acid. This leads to an increase in H+ ions, which lower muscle pH and contribute to the burning sensation and loss of power output. Baking soda acts as an extracellular buffer, helping to stabilize blood pH by neutralizing these ions.
The result is a delay in muscle fatigue, improved high-intensity endurance, and enhanced repeated-sprint performance. It’s particularly beneficial for activities involving repeated bouts of intense effort lasting between 30 seconds and 7 minutes—such as MMA rounds, CrossFit WODs, or sprint intervals.
What Types of Athletes Benefit Most?
Athletes who participate in short, intense, and repeated bouts of exercise stand to gain the most from baking soda. This includes sprinters, wrestlers, boxers, martial artists, CrossFitters, cyclists, and strength athletes who perform multiple sets under fatigue.
Endurance athletes may benefit too, especially during the sprint finish or high-output climbs. However, the benefits are more pronounced in anaerobic or glycolytic efforts, where acidosis is a primary limiting factor.
The Science of Acidosis and Buffering
As your muscles work at high intensity, glucose is broken down into lactate and H+ ions. These ions lower the pH in muscle cells, leading to fatigue and impaired function. The body has its own buffering systems—primarily bicarbonate in the blood—but they can be overwhelmed during intense efforts.
Supplementing with sodium bicarbonate increases the amount of bicarbonate available in the bloodstream, enhancing the body’s ability to remove H+ ions and maintain optimal muscle function during hard training or competition.
Evidence-Based Benefits of Baking Soda Supplementation
Multiple studies have demonstrated that baking soda can improve performance in high-intensity sports. Research published in the *Journal of Applied Physiology* and *International Journal of Sport Nutrition and Exercise Metabolism* shows significant improvements in time-to-fatigue, total work output, and sprint performance.
On average, athletes see a 1–3% performance boost—enough to separate first from fifth place in competitive events. When combined with proper dosing strategies, the benefits can be substantial without side effects.
Classic Dosing Protocols (and Their Pitfalls)
The traditional loading protocol involves taking 0.3 grams of baking soda per kilogram of body weight about 60–90 minutes before exercise. For a 70 kg person, that’s roughly 21 grams. While effective, this method is infamous for causing gastrointestinal distress, including bloating, cramping, and diarrhea.
The large, one-time dose overwhelms the digestive system and often deters athletes from continued use. That’s why newer, more tolerable dosing strategies are gaining traction for both competitive and recreational use.
The GI Distress Problem
The primary downside of baking soda supplementation is gastrointestinal discomfort. Taking too much at once can create a laxative effect due to the high sodium load and its impact on stomach pH. This is a major reason why many athletes abandon its use after just one try.
The key to successful use is to minimize GI distress through better absorption techniques—such as lower doses, split dosing, or encapsulation. Hydration and meal timing also play a crucial role in reducing symptoms.
Split Dosing Strategies
Rather than taking the full amount at once, split dosing involves dividing the total dosage into multiple smaller servings over several hours. For example, instead of consuming 20 grams all at once, you might take 5 grams every 20 minutes over an hour and a half.
This method gives the body more time to absorb bicarbonate without overwhelming the digestive system, making it much more tolerable for most users while preserving performance benefits.
Microdosing Over Several Days
Microdosing involves taking smaller daily doses of baking soda (0.1–0.2 g/kg) over several days leading up to competition. This strategy gradually raises plasma bicarbonate levels without causing digestive upset and may even extend the buffering benefits over multiple days.
Some studies suggest that microdosing is nearly as effective as acute loading when used consistently and may be ideal for events with multiple heats or rounds spread across days.
Enteric-Coated Capsules: A Game-Changer
Enteric-coated baking soda capsules are designed to bypass the stomach and dissolve in the intestines, drastically reducing GI side effects. These are ideal for athletes who want to benefit from bicarbonate loading but can’t tolerate raw powder.
They also offer more accurate dosing, convenient transport, and better timing for event-day use. For athletes sensitive to sodium bicarbonate, enteric-coated capsules offer the most practical solution.
Baking Soda vs. Beta-Alanine
Both baking soda and beta-alanine are buffering agents, but they work differently. Beta-alanine increases carnosine levels inside the muscle cells to buffer H+ ions from within, while baking soda works outside the muscle in the bloodstream.
The two can be stacked together for synergistic effects, especially in athletes who require both intracellular and extracellular buffering capacity for peak output and recovery between efforts.
Hydration and Electrolyte Balance
Baking soda contains a high dose of sodium, which can impact fluid balance. Proper hydration is critical when supplementing to avoid cramping or elevated blood pressure. Pair sodium bicarbonate with magnesium and potassium to maintain electrolyte equilibrium.
Athletes who sweat heavily should be especially mindful of hydration status, as baking soda can shift water balance. Drinking 500–750 ml of water during the loading phase helps improve absorption and reduce GI symptoms.
Who Should Avoid Baking Soda?
While generally safe for healthy individuals, people with high blood pressure, kidney disease, or sodium-sensitive conditions should avoid baking soda supplementation unless approved by a medical professional. It’s also not recommended for endurance athletes during prolonged efforts due to its high sodium content.
For those with contraindications or sensitivity, consider alternative performance enhancers like creatine, beta-alanine, or nootropics that support focus and power output—such as Huperzine A.
Stacking for High-Intensity Performance
Stacking baking soda with other proven supplements can maximize your performance. A smart stack might include creatine for ATP production, beta-alanine for intracellular buffering, and Huperzine A for mental sharpness and neuromuscular control during high-output efforts.
Huperzine A is a cognitive enhancer that supports acetylcholine levels in the brain, improving memory, focus, and mind-muscle connection—an ideal companion for complex, high-skill workouts.
Timing Your Doses for Best Results
If using the traditional protocol, take your full dose 60–90 minutes before training. For split dosing, begin 2–3 hours out and finish your last mini-dose 30 minutes before your session. Microdosing can be done once daily for 3–5 days before peak performance.
Always test your tolerance during training—not on competition day. Every body responds differently, and optimal timing will vary based on your digestion speed and exercise intensity.
