L-Phenylalanine supports neurotransmitter, mental energy and alertness, appetite and body weight regulation, and healthy mood. 

LPA is an essential amino acid which can be converted to L-tyrosine through a series of biochemical process which takes place in the liver. L-tyrosine can be converted by neurons in the brain to dopamine and norepinephrine (noradrenaline), These neurotransmitters are depleted by stress, overwork and certain drugs. By replenishing norepinephrine in the brain, mental energy levels are enhanced and a feeling of contentment often occurs. By contributing to the synthesis of dopamine and norepinephrine, LPA may also help to regulate appetite and body weight by promoting a healthy mood. 

Caution: KEEP OUT OF THE REACH OF CHILDREN. Contains phenylalanine. Individuals with the rare metabolic disorder Phenylketonuria should not take this amino acid. Not to be used with antidepressant drugs such as MAOI's or SSRI's. Since both norepinephrine and epinephrine can cause smooth muscle (arterial) contraction, care with blood pressure should be taken when supplementing L-phenylalanine. Large amounts of L-Phenylalanine may affect your blood pressure and cause headaches, nausea and heartburn.

(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.
