Amino X 1kg for Intra-Workout and Recovery Support

BSN Amino X delivers 10g of free-form amino acids per 14.5g scoop at 51kcal, including 2g L-leucine, 1g L-isoleucine, 1g L-valine, 3.5g L-alanine and 2.5g taurine, alongside 0.49mg vitamin B6 and 2.5mcg vitamin D. The stimulant-free formula is effervescent and sugar-free. The 1kg tub provides 69 servings across multiple flavours.

Free-form amino acids bypass digestion and absorb directly into the bloodstream, making them available faster than protein-derived aminos from food or a shake. The BCAA fraction (leucine, isoleucine, valine at 2:1:1) supports muscle protein synthesis and reduces muscle protein breakdown during training. L-alanine at 3.5g contributes to energy production via the glucose-alanine cycle - a relevant pathway during prolonged aerobic output. Taurine supports cellular hydration and muscle function. Vitamin B6 contributes to normal protein metabolism and energy-yielding metabolism.

At 69 servings from a 1kg tub, Amino X provides meaningful value for an amino acid drink in the category. The effervescent format makes it a practical intra-workout option - lighter on the stomach than a protein shake mid-session and easy to sip through a warm-up or during rest periods. The stimulant-free formulation means it can be used across any session regardless of pre-workout intake and at any time of day without affecting sleep.

Built for gym-goers and endurance athletes who want a flavoured intra-workout or between-meals amino drink. The formula covers BCAAs but not the full nine essential amino acids - not the right choice for anyone specifically seeking a complete EAA product. Contains soy lecithin. Produced in a facility that processes milk.

Alternatives: Strom EssentialMax EAA 450g (14.4g total EAAs including all 9 essentials) for a complete amino acid profile, or Applied Amino Fuel EAA 390g as an intra-workout EAA drink with comparable serving count.

Frequently Asked Questions

Who is BSN Amino X best suited to?

BSN Amino X is best suited to people who want a more deliberate hydration option they can use consistently. It works best when you want something practical that fits a repeatable routine rather than a dramatic one-off.

When should I use BSN Amino X?

The best time to use BSN Amino X depends on the format and the rest of your routine, but most people get more from it when it sits in a consistent daily or around-training slot. Consistency usually matters more than chasing a perfect time.

What makes BSN Amino X a practical option?

BSN Amino X is practical because it is built to help you stay on top of hydration around sweating and longer sessions without adding much friction to the rest of the day. That ease of use is often what makes a product stay in the routine long enough to be worthwhile.
