What are TCO₂ Readings and How Can Equestrolyte Affect Them?

For those in the equine racing and performance industry, understanding TCO₂ readings is essential, as they play a critical role in ensuring fair competition and the overall well-being of horses. Here, we’ll explore what TCO₂ readings are, why they matter, and how Equestrolyte is formulated with specific ingredients to support your horse’s performance without causing a significant impact on these readings.

What is TCO₂ and Why Does It Matter?

TCO₂, or Total Carbon Dioxide, is a measure of the total amount of carbon dioxide present in the blood, which includes dissolved CO₂, carbonic acid, and bicarbonate. In horses, TCO₂ readings are commonly used as an indicator of acid-base balance. Bicarbonate is a natural buffer that helps maintain a stable pH in the bloodstream, essential for muscle function and general health, especially during intense exercise.

High TCO₂ levels can sometimes suggest the use of buffering agents intended to artificially delay fatigue by preventing the natural buildup of lactic acid in muscles during strenuous activities. Because elevated TCO₂ levels can indicate a performance-enhancing intervention, most racing authorities set strict limits, often around 35.1 mmol/L. Horses exceeding this threshold may face penalties or disqualification from races.

How Do Buffering Agents Affect TCO₂?

Certain buffering agents, particularly sodium bicarbonate, are known to increase bicarbonate levels in the bloodstream, leading to higher TCO₂ readings. Sodium bicarbonate, also known as “bicarb” or “baking soda,” is commonly used in many sectors to manage acidity. However, in performance horses, excessive use of such buffers can artificially boost endurance and delay muscle fatigue, which is why its use is carefully monitored in the racing industry.

Buffers like sodium bicarbonate work by helping to maintain the body’s pH balance during intense exercise. During high-performance activities, a horse’s muscles produce lactic acid as a byproduct of anaerobic metabolism, leading to a drop in pH levels in the muscles and bloodstream, which causes fatigue and muscle 'burn.' Buffering agents like bicarbonates counteract this by neutralizing excess acid, keeping pH levels more stable. This buffering effect delays the buildup of acidity, allowing muscles to keep contracting effectively for a longer period and, in turn, extending endurance and delaying the onset of fatigue. While helpful, this effect can be seen as performance-enhancing, which is why elevated TCO₂ levels—indicating excess buffering—are regulated in racing environments.

Other common buffering agents include calcium carbonate and potassium bicarbonate, which similarly work to neutralize stomach acid and can also contribute to elevated TCO₂ readings. Because of these effects, it is essential to choose buffering agents that offer gastrointestinal benefits without pushing TCO₂ levels beyond regulatory limits.

How is Equestrolyte Different?

Equestrolyte is formulated with a unique blend of buffering agents that provide acid-neutralizing support while minimizing any potential impact on TCO₂ levels. Instead of strong bicarbonate sources, Equestrolyte contains Acid Buf, a natural buffer derived from marine algae, along with magnesium oxide and magnesium hydroxide. Here’s how each component contributes:

• Acid Buf: With 3.6g of Acid Buf in each 60g daily dose, Equestrolyte offers a gentle, sustainable buffering effect. Acid Buf is derived from calcareous marine algae and provides bioavailable calcium and trace minerals. This unique buffering agent supports gastric comfort without spiking TCO₂ levels like traditional bicarbonate products.

• Magnesium Oxide and Magnesium Hydroxide: Each 60g daily dose of Equestrolyte contains 0.6g of magnesium oxide and 0.6g of magnesium hydroxide. These mild antacids work alongside Acid Buf to neutralize stomach acid gradually. Their contribution to TCO₂ levels is minor, helping to maintain digestive health without creating significant increases in blood bicarbonate levels.

Why These Ingredients?

The buffering agents in Equestrolyte were carefully selected to offer sufficient acid-neutralizing power to protect the horse’s stomach and maintain optimal gut health while ensuring a minimal impact on blood TCO₂ levels. This approach makes Equestrolyte an ideal choice for routine use, providing peace of mind for those concerned about TCO₂ regulations.

Practical Usage Tips for Equestrolyte

While Equestrolyte is designed to support your horse’s performance without triggering elevated TCO₂ readings, here are some practical guidelines:

1. Follow Recommended Dosage: Using the recommended 60g daily dose ensures that your horse receives the necessary buffering support without exceeding safe levels.

2. Timing Matters: For horses competing under strict TCO₂ regulations, it may be beneficial to administer Equestrolyte at least 24-48 hours before a race. This allows any slight TCO₂ impact to stabilize before testing.

3. Monitor Baseline Levels: Knowing your horse’s baseline TCO₂ levels can help you better understand how various supplements affect them, especially if they’re on a regular electrolyte or buffering regimen.

Conclusion

Understanding TCO₂ readings and how they’re affected by different buffering agents is crucial for anyone involved in equine racing or high-performance activities. Equestrolyte offers a balanced approach, using natural buffering agents like Acid Buf, magnesium oxide, and magnesium hydroxide to support digestive health without elevating TCO₂ to concerning levels. This makes Equestrolyte a safe and effective choice for trainers and owners who want to support their horse’s health and performance without risking regulatory issues.
