Innermost The Define Booster is a science-backed, non-stimulant daily formula designed to complement an active lifestyle and healthy weight-management routine. Each serving provides 2 g of acetyl L-carnitine alongside vitamins B6 and B12.

Acetyl L-carnitine is a naturally occurring form of carnitine involved in the transport of fatty acids into mitochondria, where they can be used in energy metabolism. The acetyl form is also able to cross the blood-brain barrier, making it a popular choice for supporting both physical and cognitive wellbeing.

Vitamins B6 and B12 contribute to normal energy-yielding metabolism and help reduce tiredness and fatigue. Together, the formula provides nutritional support for energy, performance, and active lifestyle goals.

With a refreshing juicy orange flavour, The Define Booster is easy to mix with cold water and can be enjoyed at any time of day. It is best used alongside a balanced diet and regular physical activity as part of a healthy approach to body composition and definition.
