What is LDL-C/ApoB?
The LDL-C to ApoB ratio compares the amount of cholesterol per LDL particle, giving insight into particle size and distribution.
Why does it matter for long-term health and wellbeing?
It helps evaluate lipid efficiency and metabolic balance, showing how well your body transports and manages cholesterol for energy and repair.
What’s an optimal level of LDL-C/ApoB?
- LDL-C: Typically <3.0 mmol/L (reference range)
- ApoB: <1.0 g/L (reference range)
- Optimal ratio: >1.3 (indicating larger, less dense particles)
What influences LDL-C/ApoB levels?
Diet quality, physical activity, body composition, stress, sleep, and genetic factors all affect LDL particle size and count.
What does it mean if LDL-C/ApoB is outside the optimal range?
A lower ratio suggests a higher proportion of small, dense LDL particles. This can signal reduced lipid transport efficiency and an opportunity to improve dietary and lifestyle factors.
How can I support healthy LDL-C/ApoB levels?
Focus on balanced nutrition rich in unsaturated fats and fibre, maintain regular physical activity, manage stress, and prioritise adequate sleep.
