Algae as Key Immune System Supporter

Woman with ColdComplex polysaccharides present in wild blue green algae contribute to the activation Natural Killer (NK) cells, the human body’s primary immune defense mechanism. These cells travel in the blood stream in a state of rest, but can be immediately recruited into tissues by chemical signals and activated through various mechanisms to kill virus-infected and cancer cells, b) divide and make more NK cells, and c) secrete substances that attract other cells into the site. Research on the polysaccharides in DLT’s Aphanizomenon flos aquae provides strong support of activation of NK cells in laboratory tests and supports immune surveillance of NK cells in the body.

In Vitro Testing

In vitro testing confirmed the inflammation modulation and antioxidant properties of AFAninPlusTM (Hart et al 2007). 1. AFAninPlusTM contains Phycocyanin, known to inhibit the enzymatic activity of cyclooxygenase-2 (COX 2) involved in the inflammation cascade. 2. Antioxidants in AFAninPlusTM are able to enter into and protect the lipid bilayer cell membrane and protect living cells from intracellular oxidative stress. 3. AFAninPlusTM activated NK cell expression of CD69, a marker compound that indicates increased scavenging and killing of virus containing or cancerous cells.

Clinical Study on Visual Acuity and Cognitive Function

In vivo testing confirmed consumption of Aphanizomenon flos-aquae (Jensen et al 2000): 1. Significantly improved reaction time and ability to multitask according to multi-sensory input. 2. Significantly improved visual acuity as measured by the reduction in size of the Physiological Blind Spot (PBS), when compared to placebo. 3. Showed a rapid improvement in visual acuity (within 2-10 minutes). 4. Showed a prolonged result, still effective at 1 hour after consumption.

Mechanisms of action involved in the rapid improvement are attributed in part to the PEA content of Aphanizomenon flos-aquae. Additional testing showed at least part of the effect of Aphanizomenon flos-aquae on cognitive function was due to rapid oral uptake of psychoactive compounds, such as PEA.
