ALT/TG ratio: normal range and what your result means

What is ALT/TG Ratio?

The ALT/TG ratio is the relationship between Alanine Aminotransferase (ALT), an enzyme found in the liver, and Triglycerides (TG), a type of fat in the blood. This ratio helps assess liver function and metabolic health.

Why does it matter for long-term health and wellbeing?

This ratio is crucial for understanding how well the liver is processing fats, which can directly influence metabolism, energy levels, and overall wellness. Tracking it helps optimise long-term health and supports the prevention of metabolic imbalances.

What's an optimal level of ALT/TG Ratio?

While ranges can vary slightly depending on laboratory methods, the optimal ALT/TG ratio generally falls between 0.2 and 0.5 in Australian units. Specific ranges can vary based on individual health and lifestyle factors.

What influences ALT/TG Ratio levels?

Diet, physical activity, alcohol consumption, and overall metabolic health can all influence the ALT/TG ratio. Maintaining a balanced diet, regular exercise, and limiting alcohol intake support a healthy balance.

What does it mean if ALT/TG Ratio is outside the optimal range?

If the ALT/TG ratio falls outside the optimal range, it could indicate imbalances in liver function or fat metabolism, potentially pointing to areas for lifestyle improvement. This should be monitored regularly to assess trends.

How can I support healthy ALT/TG Ratio levels?

 To support a healthy ALT/TG ratio, focus on a balanced diet rich in whole foods, regular exercise, maintaining a healthy weight, and limiting alcohol and processed foods. Regular monitoring can help fine-tune these lifestyle changes.
