Carbohydrate blocker supplements are formulated to support smarter nutrition choices when you’re enjoying carbohydrate-rich meals. Many blends feature white kidney bean extract (Phaseolus vulgaris), linked with alpha-amylase inhibitor activity that may help reduce the breakdown of certain starches. At AustralianVit, you can compare options suited to everyday routines in Australia, with pricing presented in AUD.

These supplements are best viewed as an add-on to consistent habits: balanced meals, adequate protein, plenty of fibre, and regular activity. Outcomes vary depending on total carbohydrate intake, portion sizes, and following label directions. They are not intended to replace healthy eating or professional medical advice.

How to use & who it suits

Carb blockers are typically taken with meals containing starches such as pasta, rice, potatoes, or bread. For a more consistent routine, prioritise hydration and choose higher-fibre whole foods where possible. If you’re pregnant or breastfeeding, managing diabetes, or using glucose-lowering medicines, speak with a qualified healthcare professional before use. Always read the label and use only as directed, and discontinue use if you experience discomfort.
