  • Energy boost
  • Promote athletic performance
  • Taste

L-Isoleucine is an essential amino acid that is routinely used by bodybuilders for energy and endurance.


Serving Size & Timing

This supplement is suggested to be taken in servings between 1000-2000mg to be consumed three times per day. It is also important to remember to take proportional elements of the other BCAAs as mentioned above. If taking one, it is necessary to take the rest.



This supplement is considered pharmaceutical grade and has no fillers of any kind.


Those who have had kidney or liver problems in the past are cautioned from taking this supplement, as are women who are pregnant or nursing. However, as long as suggested serving sizes are adhered to, it should be safe for anyone else to take.


L-Isoleucine has a bit of a bitter taste, and it is best to mix with a protein shake (as it is not very soluble in water). It should be stored in an area that is free from light, heat and moisture.

The products from Bulk Supplements are shipped and arrive quickly. Order at the beginning of the week and they arrive by the end of the week.
I have been extremely happy with every product I have purchased through Bulk Supplements. My local supplement shop has lost a customer, because of Bulk Supplements.*

i bought leucine, isoleucine and valine to take together. Works better than any other pill product I've ever tried. I will buy from bulk supplements many more times. *
