Gen-Tec L-Leucine
- Why is it recommended dosage of only 400mg of leucine on the Gen-Tec leucine container, ie 1/8 teaspoon full? The container has a big scoop.
The 400mg dose listed on the Gen-Tec Leucine container is designed to comply with Food Standards regulations. These guidelines help ensure that the product is safe for general use and legally permitted for sale in Australia.
The larger scoop inside the container is provided for those who (at their own discretion) choose to use a therapeutic or sports nutrition dose, which is typically around 2.5–3g per serve. This higher amount is supported by scientific research to help stimulate muscle protein synthesis — particularly useful for bodybuilders, athletes, or anyone aiming to maximise recovery and growth.
That said, Mr Supplement, for legal reasons, must always recommend following the dosage instructions provided on the label, unless otherwise directed by a qualified health or fitness professional.
