Xtend Supplements

At Xtend, we are whole-heartedly committed to excellence in manufacturing, research and results and nothing proves this more than the world's best selling BCAA, Scivation Xtend BCAA.

After years of doing this — and with over a century of combined experience — we are unwilling to settle for complacency or commonplace. We know we are dealing with delicate and intricate biological machinery. And we know that only those products such as Xtend BCAAs that are rigorously investigated for efficacy and relevance are worthy of the Scivation name; worthy of putting into your body.
