FAQs

If I already eat enough protein, do I need a BCAA supplement?

BCAA supplements are often used as a convenient way to consume leucine, isoleucine and valine during training. If your dietary protein intake is sufficient you may not notice a big difference, but some people enjoy sipping BCAAs for variety.

Do sugar‑free BCAAs have artificial sweeteners?

Many flavoured BCAA powders use artificial or non‑nutritive sweeteners to keep sugar at zero. Check the label for specific sweeteners if you have preferences.

When should I take BCAAs? Pre‑, intra‑ or post‑workout?

BCAAs can be taken before, during or after exercise. Many users sip them during training for taste and hydration, while others enjoy them post‑workout.

Are stim‑free BCAAs safe for evening use?

Yes. Stim‑free BCAA formulas contain no caffeine, so they’re commonly taken in the evening or before bed without affecting sleep.
