Rule 1 BCAA is an essential intra-workout recovery formula designed to protect lean muscle tissue, boost hydration, and keep you performing at your peak throughout intense training sessions. Delivering a micro-refined 5g dose of Branched-Chain Amino Acids in the proven 2:1:1 ratio, this fast-absorbing powder helps minimise muscle breakdown and kickstart recovery while you train. Whether you are lifting heavy in the gym, pushing through high-intensity cardio, or powering through demanding athletic sessions, Rule 1 BCAA provides clean, zero-sugar hydration to keep your muscles nourished.

Key Benefits & Features

• 5g Pure Micronised BCAAs: Formulated with a clinical 2:1:1 ratio of Leucine, Isoleucine, and Valine to drive muscle protein synthesis and prevent catabolism.

• Rapid Intra-Workout Hydration: Added electrolyte blend helps replenish vital minerals lost through sweat to maintain muscle function and prevent cramping.

• Zero Sugar & Zero Carbs: Delivers refreshing flavour and hydration with zero added sugars, artificial stimulants, or unnecessary caloric fillers.

• Micronised for Easy Mixing: Specially processed powder mixes smoothly into cold water without leaving gritty residue at the bottom of your shaker.

• Versatile Daily Support: Perfect as an intra-workout drink during exercise or as an all-day amino acid refresher to support continuous recovery.

How It Works

During high-intensity exertion, your body rapidly depletes circulating amino acid stores and can begin breaking down muscle tissue for energy. Rule 1 BCAA supplies a fast-acting surge of essential Branched-Chain Amino Acids directly to active muscle tissue. L-Leucine acts as the primary signal to trigger the mTOR pathway for muscle repair, while L-Isoleucine and L-Valine assist in cellular energy production and endurance.

By combining these vital aminos with essential electrolytes, Rule 1 BCAA helps preserve intracellular fluid balance and neural firing. This dual-action approach slows down neuromuscular fatigue, decreases Delayed Onset Muscle Soreness (DOMS), and ensures your muscle fibers remain protected against breakdown during heavy resistance training or caloric restriction.

Recommended Use

Mix 1 level scoop (approx. 7.2g) with 300–400ml of cold water in your Sprint Fit shaker. Consume during your workout as an intra-workout drink, or sip throughout the day between meals to boost daily amino acid intake. For maximum intra-workout hydration on hot days or during grueling sessions, mix with extra ice water.
