Aviva Customer Review

LTO3 has made an incredible difference for my 7-year-old son. I only wish I had heard about this a few years earlier! It would have saved my son a whole lot of frustration and struggles!

He started taking this last spring after we had a meeting with his teachers where they told us that grade 1 was too difficult for Jacob and he would need to repeat. He was unable to sit in his desk during class, could not remain quiet, he seldom finished his assignments and was getting very upset with himself.  We heard about LTO3 from a family member so we decided to try it ... well ... what a difference! After a few weeks he was sitting quietly, finishing all his work, and by June he passed grade 1 with hardly any more struggles!

LTO-3: Attention deficit / Hyperactivity / ADHD / Stress / Anxiety

L-Theanine (Stress - Anxiety - Concentration)

  • An amino acid derived from another (L-Glutamine); 100% pure. L-Theanine increases the brain's levels of dopamine (the pleasure and reward neurotransmitter) and serotonin (a neurotransmitter inhibiting excess stimulation), which are both decreased in a dramatic way in stressful situations.
  • Easily crosses the hemato-encephalic barrier and produces a tranquilizing effects on the brain. It also protects against neurotoxicity induced by glutamate, which is implicated in degenerative diseases.
  • Induces relaxation without causing drowsiness, an effect which can be verified by a measurably increased production of alpha waves in the brain. Studies show that it improves the brain’s concentration capacity. In contrast to caffeine, L-Theanine increases levels of GABA (gamma-aminobutyric acid), a neurotransmitter which helps induce relaxation and a feeling of well-being.
  • Quickly absorbed by the small intestine and directly transported to the brain. Efficient dosage ranges from 50 to 200 mg; only 30 to 40 minutes are needed to feel an increase in alertness and improved mental and emotional states, which can last for 8 to 12 hours.
  • Perfect for people suffering from sleep disorders (difficulty getting to sleep or feeling tired after waking up). Take one or two capsules an hour before bedtime.


Skullcap (Nervousness - Agitation - Insomnia)

Skullcap (Scutellaria lateriflora) is used to alleviate stress and anxiety as well as acting as a nerve tonic. It's also efficient in calming children's agitation, as well as relieving nervousness, insomnia and neuralgic pain. Herb-e-Concept uses the upper part of the plant and not the root.

The Difference between the Original LT03 Formulation and the "No Taste" Formulation

Sementis (in the Original Formulation)

  • Sementis is an Atlantic wild herring roe extract. Wild fish roe contains 21% to 31% of marine DNA. This powerful antioxidant has several healing properties for emotional and physical exhaustion. Sementis complex is also packed with other antioxidants including vitamin C (404 ± 150 µg/100g), Zinc (10 - 60 µg/100g) and Selenium (0,1 - 2,0 µg/100g).
  • The typical Western diet is lacking in Omega-3 and contains excessive amounts of Omega-6, which is stored by the body. Sementis offers an ideal fatty acids profile characterized by a surprisingly high Omega-3/Omega-6 ratio (36/1): Omega-3: 28.6%, and Omega-6: 0.8%. This high ratio helps reduce risks associated with several health disorders including cardiovascular issues, inflammatory problems, and immune diseases.
  • EPA: 8.3%, DHA: 20.2%
  • Studies show that as dietary support, omega-3 fatty acids are efficient in supporting treatments of depression, schizophrenia, and nervous anorexia.


Omega-3 DHA Powder-NG (in the "No Taste" Formulation)

  • Omega-3 DHA Powder-NG is extracted from fish oil sourced through eco-friendly fishing. The contaminant levels meet or exceed the high criteria of the following organizations: CE (European Commission), NFSA (Norwegian Food Safety Authority), GOED Omega-3 (Global Organisation for EPA and DHA Omega-3).
  • A microencapsulation process is used to keep all the EPA & DHA locked in. The Omega-3 sources are the purest and the best available on the market, without any smell or taste of fish. 


NOTICE: Many people see results on the first day; but in some cases it can take 2-15 days before you feel positive results. Be patient and give your system time to get familiar with LTO3. Don't forget that LTO3 is a natural product and doesn't work the same way as pharmaceuticals or chemical products. LTO3 may also help reduce the side effects of caffeine and decrease premenstrual syndrome (PMS) symptoms. Some studies show that L-Theanine may also be effective in lowering cholesterol levels and high blood pressure.
