Natural protection against viruses.

Imunivar® is an immune supporting, anti-viral health supplement containing a natural concentrated active ingredient, Fucoidan 85%, sourced from Undaria pinnatifida sea kelp.

  • The fucoidan in Imunivar® can block the entry of coated viruses to cells, thereby preventing or halting the progress of infections.3
  • Fucoidan has been shown to be a highly effective inhibitor of influenza viruses.1,3,4

Imunivar® Fucoidan 85% (Undaria pinnatifida extract ) has undergone extensive in vitro, in vivo and human clinical testing. Examples of the potential benefits and biological effects identified in this testing include:

Immune function

Increased mobilisation of CD34+ stem cells and CXCR4 expression.
Increased IgG levels by 397%.
Activation of Toll-like receptors 2 and 3 by up to 387%.

Boosting immune responses

In the elderly and while ill, one’s Immune responses to vaccines or infections could potentially not be as efficacious. Fucoidan was shown to help support the immune responses to seasonal influenza vaccines, in a clinical study.5

In healthy people, the ingestion of fucoidan supported an increase in the anti-pathogenic activity of granulocytes and macrophages. In a mouse model, the increase in immune activity was shown to eliminate the tropical protozoan parasite Leishmania.
Other positive effects of ingested fucoidan are promotion in the maturation of dendritic cells, activation of NK cells and promotion of cytotoxic activity.7

Anti-viral activity

Inhibition of the binding and entry of a range of viruses to host cells.
Significant reduction in the clinical signs of influenza and lung damage.

Inhibits viral activity

Fucoidans may prevent or halt the progress of infections by blocking the entrance of coated viruses to cells.
Other viruses that fucoidan is effective in inhibiting are the Herpes Simplex viruses (HSV1 and HSV2)8 and influenza viruses.4
it has also been shown, in vivo, that fucoidan, taken orally, inhibits lung damage and clinical signs of respiratory infection. This is due to its anti-inflammatory effect.

Research has further shown that 1-2 g of ingested fucoidan per day resulted in a decrease in clinical signs and lung damage.9 This shows that fucoidan is effective in viruses due to its modulation of pathology, no matter which pathogen is present.
