Mechanisms of Action:

Halsavit’s main ingredient, Spirulina (Arthrospira Platensis) is a unique freshwater plant that has been of an enormous interest to nutritional scientists over the past decade. Spirulina’s concentrate nutrition, as shown in Halsavits nutrient profile, makes it an ideal food supplement for people of all ages and lifestyles. It has a long history of human consumption. Currently Spirulina is used as a nutraceutical ingredient due to its unique combination of phytonutrients like phycocyanin, carotenes, xanthophylls, GLA, galactolipids, sulfolipids, chlorophyll and minerals. The three major bioactive components of Spirulina, biliprotein pigment Phycocyanin, sulfated polysaccharides and gamma linolenic acid play significant roles in improving human body functions. New experimental evidences support immunomodulation, potential health benefits and antiviral effects of Spirulina supplementation are mainly due to its chemical composition. In addition to Spirulina’s potential health effects, such as antibacterial, antioxidant, anticancer, immunomodulation and antiviral activities, some other positive effects were also observed against some disorders like malnutrition, diabetes, hyperlipidemia, inflammatory allergic reactions, obesity, anemia, heavy metal/chemical-induced toxicity and radiation damage.

Moreover, Halsavit’s second main ingredient, Ginkgo Biloba is one of the oldest living tree species, dating back over 300 million years, and individual trees can live for over 1,000 years. In China extracts of the fruit and leaves of the ginkgo tree have been used for over 5,000 years to treat lung ailments such as asthma and bronchitis, and as a remedy for cardiovascular diseases. Recently western researchers have been studying ginkgo biloba as a treatment for senility, hardening of the arteries, and as a treatment for oxygen deprivation. More than 34 human studies on ginkgo have been published since 1975, showing, among other things, that ginkgo can increases the body’s production of the universal energy molecule adenosine triphosphate, commonly called ATP. This activity has been shown to boost the brains energy metabolism of glucose and increase electrical activity.

Scientists also discovered that ginkgo contains an abundance of useful compounds including the antioxidants Vitamin C and carotenoids, but it is the flavonoid compounds collectively known as “ginkgolides” that are the most remarkable. The ginkgo flavonoids act specifically to dilate the smallest segment of the circulatory system, the micro-capillaries, which has a widespread affect on the organs, especially the brain. Researchers have also reported that Ginkgo extracts effectively increase blood circulation and increase oxygen levels in brain tissues. Ginkgo is also a powerful antioxidant that prevents platelet aggregation inside arterial walls, keeping them flexible and decreasing the formation of arteriosclerositic plaque.

Antiviral properties
Extracts from blue green algae, including Spirulina platensis, studied by researchers at the National Cancer Institute (NCI), USA yielded promising antiviral activity. The effect was mediated by a reduction in the cytopathic effects caused by the invading pathogen. Acidic polysaccharides such as calcium spirulan (Ca-SP) present in Spirulina platensis act against and inhibit the replication of several viruses. This potent and broad-spectrum antiviral activity particularly targeted enveloped viruses such as Influenza A, HIV, Herpes Simplex, Cytomegalovirus, Mumps and Measles Viruses. The cytopathic role of these viruses and replication was inhibited in human T cells, peripheral blood mononuclear cells and Langerhans cells where prevention of virus-cell attachment and fusion with host cells was observed. The Ca-SP also targeted viral absorption/penetration and some replication stages of progeny viruses. The water extract of Spirulina platensis interferes with the virus entry into host cells, particularly of HSV-1. Overall results showed that the Ca-SP, methanol (MeOH) and water extracts of Spirulina platensis were active in preventing replication of a host of enveloped viruses. These established mechanisms against RNA viruses such as SARS-CoV, Dengue, Influenza A, Mumps, Measles, Hepatitis C, HIV, all may indicate potential efficacy of spirulina platensis in a wide variety of coronaviruses as well and may even be beneficial for Covid-19.

Immunomodulatory properties

Spirulina enhances components of the mucosal and systemic immune system by activating the cells of the innate immune system. The aqueous extract of spirulina was found to have a major impact on the immune system by increasing the phagocytic activity of macrophages and stimulating the NK cells. This also enhanced NK-mediated IFNγ production. It has also been noted that in in-vivo and in-vitro it suppressed the growth of tumor cells and induced the lymphocytes in the spleen to produce TNF-α. Due to its stimulatory effects in the production of cytokines and antibodies, it also mobilized the adaptive immune system and played a role in the activation and mobilization of T and B cells. The strong IL-1β, IL-responses elicit an age-dependent enhancement of the adaptive immune response. Spirulina was also effective in potentiating the cell-mediated immunity by stimulating the Th-1 type response. A cytokine array test was performed noted that spirulina had an increased effect on the expression of genes encoding the chemokines interleukin (IL)-8, IP-10, the cytokines TNF-α, IL-1β, and the enzyme cyclooxygenase-2 (COX-2). Moreover, the effects of phycocyanin (a biliprotein of Spirulina) is seen to enhance the biological defense activity by reducing allergic inflammation. This is carried out by suppression of antigen-specific IgE antibodies and through maintaining the mucosal immune system function against infectious diseases.

Antioxidant properties

A phytochemical richly present in Spirulina, phycocyanobilin, mimics the potent inhibitory impact of biliverdin and free bilirubin on NADPH oxidase complex, thereby inhibiting its activity and promoting synthesis of increased antioxidant reduced glutathione (GSH) and reducing oxidized glutathione (GSSG). This decreases oxidative stress as well as concentrations of free radicals. Phycocyanin has been observed to play a major role in scavenging hydroxyl and peroxyl radicals. A double-blind, placebo-controlled study performed on individuals after exercise, showed decreased creatine kinase when they were supplemented with Spirulina. There was also a marked increase in exercise performance and GSH concentrations and a reduction in lipid peroxidation owing to the antioxidant properties of Spirulina. Protein extracts containing phycobiliproteins have been postulated to provide protection against teratogenesis secondary to reactive oxygen species by reducing oxidative stress. Protein extract and the biliprotein phycocyanin increase GSH in cells in order to reduce oxidative stress induced by iron. This was discovered by exposing human neuroblastoma cells in vitro to toxic amounts of iron and then to Spirulina. It was observed that Spirulina effectively protects the activity of the cellular antioxidant enzymes and reduces iron-induced oxidative stress as well as radical-mediated cell death. Geriatric patients who were administered Spirulina for 16 weeks showed a remarkable improvement in the antioxidant potential, as measured by the increased levels of antioxidant status in plasma of these individuals. Reversal of age-related declines in memory and learning were also observed.

    • 6g of spirulina for 4 weeks was associated with prolonged time to exhaustion in a 2-hour run secondary to increased fat oxidation, and also suppressed parameters of oxidation. (91)
  • A natural Anti-viral that helps reduce viral load
    • This potent and broad-spectrum antiviral activity of Halsavit particularly targets RNA enveloped viruses such as Influenza A, HIV, Herpes Simplex, Cytomegalovirus, Mumps and Measles Viruses. Established mechanisms against RNA viruses such as, Dengue, Influenza A, Mumps, Measles, Hepatitis C, HIV, all indicates potential efficacy of spirulina platensis in a wide variety of coronaviruses and may be beneficial for Covid-19.
    • Spirulina, in Halsavit is capable of inducing a sustained virologic response in some persons with Hepatitis C, at about 20% of persons (13.3% complete, 6.7% with some degree of improvement) (87)
  • A potent Antioxidant with free radical scavenging capabilities
    • 8g of Spirulina for 4 months was associated with improved lipid profile, immune variables, and antioxidant capacity; more-so in females, but favorable inflammatory changes in men. (89)


  • Immunity booster with innate and adaptive immunomodulation properties
    • Two pilot studies, independent and their results combined, note increases of NK cell mRNA and subsequent NK cell tumor-killing activity with 200-400mg Spirulina a day. (86)
    • 3g Spirulina daily for 12 weeks in elderly persons with a history of anemia improved blood parameters (without influencing RBC) and increased WBC count. (88)
  • Inflammatory Disorders:
    • It exhibits an anti-inflammatory activity by acting on the cyclo oxygenase enzyme 3, inhibiting production of prostaglandins and leucotrienes.
  • Helps manage Type 2 Diabetes:
    • In a human study, Spirulina supplementation at 2 g/day for 2 months given to diabetic patients improved glycosylated hemoglobin (HbA1C) and favorably altered the serum lipid profile. These studies show that Spirulina can be used as a functional food to manage Type 2 Diabetes.
  • Hypertension:
    • In humans, Spirulina reduced blood pressure in hypertensive subjects when given 4.5 g Spirulina for 6 weeks. Spirulina supplementation reduced both systolic and diastolic blood pressure in subjects.
  • Cholesterol Reduction
    • Spirulina consumption reduces Serum cholesterol levels by 4.5% in 4 weeks.
    • In a human study, the effect of orally supplemented Spirulina (4.5 g/day, for 6 weeks) was evaluated in Mexican population. Spirulina significantly reduced serum triglyceride values and boosted HDL and lowered total cholesterol in the test subjects.
  • Anti-Cancer Activity
    • Evaluation of chemo prevention of oral cancer with spirulina evaluated the chemo preventive activity of spirulina (1 gm./day for 12 months) in reversing oral leukoplakia in pan tobacco chewers in Kerala, India.
    • Complete regression of lesions was observed in 20 of 44 (45%) evaluated subjects supplemented with spirulina, as opposed to 3 of 43 (7%) in the placebo arm.
    • Certain special enzymes called “Endonucleases” repair damaged DNA to keep cells alive and healthy. When these enzymes are deactivated by toxins or radiation, errors in DNA go un-repaired and may eventually result in cancer. Spirulina prevents deactivation of Endonucleases, thereby preventing and even correcting early cancers.
    • Enhancement of endonuclease activity and repair DNA synthesis by polysaccharide of spirulina.
    • Exhibited inhibitive effect and mechanism of polysaccharide of spirulina on transplanted tumour cells in mice.
  • Radiation protection
    • Ionizing radiation can cause mutations in the bone marrow cells. Spirulina polysaccharide was shown to reduce mutagenesis in animal studies.
  • Lipid peroxidation Inhibition in arthritis, Alzheimer’s, immunological disorders:
    • Lipid peroxidation causes damage to cell membranes. Research suggests that phycocyanin present in spirulina inhibits lipid peroxidation at a concentration of 5oomM in rats microsomes
  • Anti-platelet:
    • It inhibits platelet aggregation by reducing prostaglandin mediated thromboxane A2 formation, thus acting as a thromboxane synthase inhibitor.
  • Neurodegenerative Disorders:
    • Neurodegenerative disorders like Parkinson’s and Alzheimer’s are associated with oxidative stress. Preclinical experiments with rats showed that phycocyanin had potential to prevent oxidative stress produced in the hippocampus of experimental animals.
  • Age related Cognitive Decline:
    • Age related cognitive decline can be due to inflammation related oxidative damage to the central nervous system (CNS). Diet high in antioxidant activity is able to reduce this decline. Spirulina was shown to reverse age-induced decreases in cerebellar β-adrenergic function in rats, and this effect may be due to high antioxidant capacity of Spirulina.
  • Neurogenesis:
    • Neurogenesis or production of new neurons is a lifelong occurrence, and necessary for learning. Inflammation causes a decrease in neurogenesis. In a rat model, diet enriched with Spirulina was able to negate this inflammation related decrease in brain neurogenesis.
  • Neuroprotective:
    • Spirulina was shown to have neuroprotective effects against transient focal ischemia in rats. This effect could be due to the decrease in pro inflammatory cytokines with Spirulina diet.
  • Kidney detoxification
    • Scientific studies suggest Spirulina may have a beneficial effect for humans suffering from heavy metal poisoning and that kidney side effects may decrease when spirulina is taken with the administration of drugs.

Anemic Patients:

Spirulina stimulates production of stem cells by bone marrow.

Suffering from arthritis:

Gamma linoleic acid manages inflammation and prevents arthritis.

Renal Failure:

Applicable to the management of general renal dysfunction and heavy metal poisoning.


Side effects and adverse effects:

The Dietary Supplements Information Expert Committee of the United States Pharmacopeia reviewed the safety of spirulina in 2011. The committee unanimously voted for a Class A safety assignment for spirulina, meaning that available evidence did not indicate it to pose a serious health risk when properly formulated and used.

In spite of the wide usage for the beneficial effects, a few side effects and contraindications have been reported with spirulina use. The most frequently reported adverse effects are headache, muscle pain, flushing of the face, sweating, and difficulty concentrating. These have been described in people taking 2 tablets or 20ml of Halsavit. Skin reactions have also been reported. Spirulina should be avoided by people who have the metabolic disorder phenylketonuria, as phenylalanine content can be harmful.

Drug Interactions:


Dosage and administration:

Oral route the tablets should be swallowed, without chewing, with half a glass of water at the end of a meal.

Syrup can be taken at the end of a meal.
