L-Isoleucine is an essential amino acid. It can not be made by the body, and must be acquired through food or supplements. The male adult’s daily requirement is 10 mg/Kg body weight. It has numerous health and athletic performance benefits. L-Isoleucine is known as one of the three branched chain amino acids (BCAAs, L-isoleucine, L-valine, and L-leucine). It is used in combination with the L-leucine and L-valine to improve the nutritional status of people. The combination ratio is usually 2:1:1 (L-leucine : L-isoleucine : L-valine). BCAAs serve as important fuel sources for skeletal muscle during periods of metabolic stress. BCAAs may promote protein synthesis, suppress protein catabolism and serve as substrates for gluconeogenesis. BCAAs are catabolized in skeletal muscle, stimulating the production of L-alanine and L-Glutamine, and other substances.

(4). For International Buyers, please read following carefully before you decide to order (Including domestic buyers asking for shipping to an address outside USA)

International shipping is complicated. Different country has different regulation. While most foreign countries permit to import our store listing products, some countries' customs may restrict or ban some of the products. Would you please consult your country's customs to see if there is any restriction to the product, before you order, to avoid unnecessary money loss. It is your own responsibility, if your packages are confiscated/destroyed/held/seized by your country’s customs, we do not refund any of your payment.

If we can be aware of your country's restrictions according to our international shipping experience, we will ask you to cancel your order and then refund all your payment. But we cannot guarantee having the awareness of your country’s customs regulation.

It is international buyer’s (or receiver’s) responsibility to pay import tax and any other fee incurred from your country’s Customs or any other organizations, if there is that.

International shipping carrier is USA Postal Service (USPS). This low shipping fee which we collect for international shipping is only for regular postal international shipping service. We can only provide you Customs Form number of your package and evidence of shipment, but it is not a tracking number, without any tracking details. If you want a tracking number (especially for high value products), you can spend additional US$12 cost for extra Register Mail Service, then you can get a Registration tracking number.

We always ship out international order as soon as possible once all the conditions are clear. The international delivery time is variable from anywhere of 2 to 6 weeks, sometimes even longer time, depends on your country’s Customs Checking and Clearance situations, and Postal Service conditions.
