PHYSICIAN ENDORSED#

Fish Oil Fish oil provides heart healthy omega-3s, which are essential long chain fatty acids that play a critical role in everyday body functions.

The omega-3 fatty acids found in fish oil are necessary for heart, joint, skin and eye health. They help maintain healthy cholesterol levels and are necessary in the maintenance of normal blood pressure.*

These important bone-strengthening components are essential for bone health and teeth.*

L-theanine is naturally found in green tea, and has been used since ancient times for its calming and relaxing benefits.*

^In a randomized, double-blind, placebo-controlled study of 112 healthy volunteers, subjects taking the GNC vitamin and mineral blend in this product for six weeks experienced statistically significant improvements in markers of B vitamin and antioxidant status, as well as improvements in SF-36 Vitality and Mental Health scores compared to those taking a placebo.
