BSN Amino X is marketed as a stimulant‑free amino acid / BCAA supplement, aimed at supporting muscle endurance, recovery, and protein synthesis.
Each serving delivers about 10 g of amino acids (including BCAAs and other amino acids like L‑Alanine, Taurine, L‑Citrulline).
The BCAA portion typically follows the common 2:1:1 ratio (Leucine : Isoleucine : Valine) for supporting muscle protein synthesis.
| Content / Component | Approximate Amount / Info |
|---|---|
| Amino acids total | ~ 10 g total amino‑acid blend |
| BCAAs (Leucine : Isoleucine : Valine) | ~ 4 g (Leucine 2 g, Isoleucine 1 g, Valine 1 g) |
| Other amino acids (e.g., Alanine, Taurine, Citrulline) | Included in the blend (e.g. Taurine, Alanine, L‑Citrulline) |
| Calories / Carbs / Sugar | Very low — carbs < 1 g, sugar ~0 g. |
| Additional nutrients | Sometimes includes Vitamin D (depending on formula) |
| Flavoring / additives | Natural / artificial flavors, sweeteners (e.g. sucralose), emulsifiers, anti‑caking agents, etc. |
According to BSN and retailers, Amino X is intended to help with:
Enhanced muscle recovery after workouts.
Supporting muscle endurance and performance during workouts (especially long or intense sessions).
Helping with protein synthesis / muscle building & maintenance — as amino acids are the building blocks of protein.
Being a low‑sugar, caffeine‑free supplement makes it viable to take before, during or after workouts, or even at other times without interfering with sleep or diet.
Typical serving: mix 1 scoop (≈ 14.5 g) with ~200–240 ml cold water (or any beverage).
Timing: You can take it before, during, or after workouts.
Some sources mention possibility of two servings per day (e.g. for intense training days) — but should stay within recommended use.
Amino‑acid supplements (like Amino X) are not a substitute for full‑value dietary protein (e.g. from food). They are meant to supplement — not replace — a balanced diet.
Contains additives: flavorings, sweeteners, emulsifiers, possibly soy lecithin (so not ideal for people with soy allergy).
As with any supplement: effectiveness depends on overall diet, total protein intake, training, rest — you can’t rely on it alone to build muscle or improve performance.
It’s a fairly popular choice for:
People doing regular workouts (weight training / resistance / endurance) who want extra support for recovery, endurance, and muscle maintenance.
Those who prefer a light, low‑sugar, easily mixable amino supplement (instead of heavier protein powders).
Athletes who need BCAA / amino support but don’t want stimulants (since Amino X is caffeine‑free).
