INTENDED FOR USE BY PERSONS UNDER THE AGE OF 18. KEEP OUT OF THE REACH OF
CHILDREN. If you are
pregnant or breast feeding, consult your health
 care professional before using
this product. People with known medical conditions and/or taking drugs should
consult with a licensed physician and/or pharmacist prior to taking any dietary
supplements. Do not take in conjunction with MAO inhibitor drugs. Not for use by
persons with a history of malignant melanoma or if bipolar, pregnant, suspect

associated with increased dopamine levels such as mania and schizophrenia. This
supplement may increase sensitivity to the effects of CNS stimulants. Caution is
advised when taking tyrosine along with stimulants and dosages should be lowered
accordingly. Keep out of the reach of children.
L-Tyrosine side effects:
L-Tyrosine may help some people in their fight against depression, but dosages
above 500 mg, in some people, may cause anxiety, restlessness and rapid heart
rate. L Tyrosine can cause over stimulation, restlessness, anxiety, and
insomnia. Heart palpitations or arrhythmias are potential side effects that
occur from high doses of tyrosine. These can occur in sensitive individuals in
as low a dose as 200 to 500 mg. Always start with a low dose, such as 200 mg or
less, even if it means opening a tyrosine capsule and taking a portion of it.

Certificate of Analysis
Proves Quality & Freshness: Always know the expiration date of a
supplement before you purchase. If the manufacturer won't give you the
expiration date and a Certificate of Analysis than beware. Many online venders
sell expired or nearly expired products which they get on closeout from
distributors who can no longer sell them to stores. NutraBio.com guarantees that
this product is from the freshest and purest raw ingredients available and was
packaged within the last two weeks. Click on the red "Purity & Freshness Seal"
at the top of the page to view the actual Certificate of analysis.
Beware of
inferior packaging: How your supplements are packaged can
be just as important to their freshness and quality as the
ingredients themselves. All NutraBio supplements are packaged in
HDPE (high density polyethylene) bottles. These bottles keep
moisture vapor and harmful UV rays out, protecting the freshness and
integrity of their contents. HDPE bottles are 400% more effective as
compared other brands currently using PET (polyethylene
terephthalate) bottles. HDPE bottles do not break as glass can and
are also recyclable so we urge you to please recycle them.
Beware of
companies claiming to save you money by putting their supplements in
plastic baggies. These are usually companies operating
out of their house or small facilities that do not have the proper
equipment and technology to manufacture and package  supplements
under clean, sanitary conditions as required by the FDA and CGMP
guidelines. LDPE (low density polyethylene) clear baggies allow UV
light, air and airborne contaminants to come in contact with their
contents, which can degrade active ingredients and deteriorate their
freshness.
