This is important because these plant ingredients provide beneficial antioxidants adding additional benefits. See the research below.


The Sharp Focused formula also contains L-Theanine an amino acid found in tea. This is the ingredient that helps you feel calm, so this formula helps to increase your energy and focus, but at the same time helps to keep you calm.


Guarana has demonstrated a high antioxidant activity, and a group of people taking guarana regularly showed lower LDL oxidation when compared with a group that did not (Portella Rde L, et al., 2013).

LDL oxidation is a major risk factor for cardiovascular disease.


Green coffee supplementation has been found to improve fasting blood glucose, insulin, and total cholesterol (Asbaghi O, et al., 2020). When the green coffee extract was taken for 8 weeks or more, a reduction of LDL was also seen.


When 27 studies were reviewed, all of them randomized placebo-controlled trials, green coffee supplementation significantly decreased fasting blood glucose, insulin, triglycerides, and increased HDL, the so-called good cholesterol (Morvaridi M, et al., 2020).


When green coffee extract, guarana, and L-Theanine are taken together, not only will you get the benefits of increased energy and focus as well as the benefits of antioxidants, but L-Theanine provides calm, relaxation, and focus. L-Theanine has been found to produce anti-stress effects (Kimura K, et al., 2007).


If you want to feel even calmer, but still energetic, you can experiment by adding 1 capsule at a time of the L-Theanine EF formula we have.

1 capsule of the L-Theanine EF contains 100 mg of L-Theanine and is perfect to experiment with, just add 1 capsule at a time until you feel the way you like to feel. L-Theanine has not been found to produce any side effects even with a huge dose.
