Nduranz
Bicarb 180 capsules

Nduranz Bicarb is a supplement containing sodium bicarbonate in delayed-release, enteric-coated capsules. It serves as an acid buffer, helping maintain optimal blood and muscle pH during high-intensity exercise. This can delay fatigue and support performance in HIIT intervals, sprints, or the final stages of races. Sodium bicarbonate is one of the most researched ergogenic aids in sports science.

The recommended timing is 60 minutes before intense exertion—a standard dose is 10 capsules (10 g) taken with at least 500 ml of water. If adjusting for body weight (0.2–0.3 g/kg), split the dose into two: take the first half 2 hours and the second half 1 hour before exertion. Correct timing is key to maximizing the buffering effect.

Each capsule contains exactly 1 g, making dosing easy. Calculate 0.2–0.3 g per kilogram of body weight. For example, a 70 kg athlete would take 14–21 capsules (14–21 g). The standard dose is 10 capsules (10 g). For higher doses, we recommend splitting: take the first part 2 hours and the second 1 hour before performance.

A bottle of 180 capsules provides 18 standard doses at 10 capsules (10 g) per serving. If you use 15 capsules per dose based on weight, it provides 12 servings. It is a practical, cost-effective pack for 4–5 intense sessions per week at standard dosage.

Enteric coating ensures the capsules pass through the stomach undissolved, releasing the active ingredient only in the small intestine. This significantly reduces digestive distress—bloating, nausea, and diarrhoea—which are common with loose baking soda. It also removes the unpleasant salty taste, resulting in better tolerance while maintaining full buffering efficacy.

Sodium bicarbonate can cause digestive issues like bloating or nausea in sensitive individuals. The enteric coating minimises these risks compared to loose baking soda. The product is high in sodium, so limit intake from other sources. Start with a lower dose to assess your individual tolerance.

Yes, sodium bicarbonate naturally contains high sodium (about 27% of its molecular weight). A 10 g dose contains approximately 2700 mg of sodium. Therefore, limit salt intake from other sources like meals, electrolyte drinks, or other supplements while using this product.

Yes, it is vegan-friendly. The capsule is made from HPMC and amidated pectin—both plant-based. The product contains no allergens and is compatible with both vegan and vegetarian diets.

No, it contains no common allergens. The formula—sodium bicarbonate, magnesium salts of fatty acids, silicon dioxide, HPMC, and amidated pectin—is free from gluten, lactose, soy, and nuts, making it safe for those with intolerances or coeliac disease.

While both contain sodium bicarbonate, the delivery method is key. Loose powder from a pharmacy tastes poor and dissolves in the stomach, increasing bloating risks. Nduranz Bicarb passes the stomach, releasing in the small intestine, which ensures better tolerance and precise 1 g dosing without the bad taste.

These are different substances. Sodium bicarbonate is an extracellular buffer used acutely before exercise. Beta-alanine increases intracellular carnosine stores and requires long-term daily intake. They can be combined for maximum buffering effect as they work on different levels.

Yes, it can be combined with most common supplements. For long or very intense races, the manufacturer recommends supplementing 5 g per hour, for example with Nduranz Nrgy Drink Bicarb 45. Be mindful of total sodium intake when mixing with electrolyte drinks.

It is ideal for cyclists, runners, triathletes, rowers, swimmers, Hyrox competitors, CrossFit athletes, and anyone doing HIIT, sprints, or competitive racing. It is effective in team sports and martial arts involving repeated high-intensity bursts, especially where anaerobic work causes high lactate buildup.

It works acutely on the day of use. Once the enteric-coated capsules reach the small intestine, plasma concentration peaks within 60–90 minutes. That is why we recommend taking it 60 minutes before exercise for immediate performance support.

Yes, it can be used for long events. We suggest supplementing roughly 5 g per hour, perhaps combined with Nduranz Nrgy Drink Bicarb 45. Remember that the buffering effect is most pronounced during short, high-intensity efforts rather than long, steady-state aerobic activity.
