Spirulina Boosts Immunity and Insulin Sensitivity, Fights HIV

(Last Updated On: November 14, 2018)

spirulina boosts immune system in HIV patientsSpirulina fights HIV and significantly boosts the immune system according to a number of recent studies. Other studies have found that spirulina boosts insulin sensitivity and improves cholesterol.

Yes, spirulina is a serious green medicine. It is also one of the most nutrient-dense supplements, and one of the easiest to grow.

Spirulina is also one of the most studied microalgae. It has been studied for a variety of conditions. Most of these studies have been upon mice and rats.

And yes, spirulina was shown to be useful in most of these studies. But now finally we’re finding that these successful applications are also applicable to humans. Let’s look at a few of the more significant applications of spirulina from human studies.

Spirulina improves insulin sensitivity and more

Researchers from Poland’s University of Medical Sciences studied 50 obese patients with insulin resistance and poor cholesterol levels in a 2017 study. The patients also experienced higher inflammation levels, as

The researchers gave half the patients 2 grams (2,000 milligrams) of spirulina daily. The other half were given a placebo. After three months of supplementation, the researchers retested the patients – for their insulin sensitivity levels, their LDL-cholesterol levels and their interleukin-6 levels to test their inflammation levels.

The researchers found that the spirulina significantly reduced their LDL cholesterol levels, boosted their insulin sensitivity levels, and decreased their inflammation levels.

The scientists concluded:

“The favorable influence of Spirulina supplementation on insulin sensitivity, plasma lipid levels along with inflammation and oxidative stress biomarkers reported in this study creates the promise for new therapeutic approaches in obese patients with well-treated hypertension.”

Spirulina improves immunity

In a 2018 study from Poland’s Pomeranian Medical University, researchers studied 19 members of the Polish Rowing Team. The researchers gave 10 of the rowers 1,500 milligrams of spirulina extract for six weeks. The other 9 rowers were given a placebo.

The researchers tested all the rowers for their a variety of immunity markers. These included:

  • T regulatory lymphocytes (Tregs – CD4, CD25, CD127)
  • Cytotoxic lymphocytes (CTLs – CD8, CRαβ)
  • Natural killer (NK) cells (CD3, D16, CD56)
  • TCRδγ-positive cells (Tδγ)

The researchers found that after only six weeks of supplementation with such a small amount (1.5 grams) of spirulina per day, that the spirulina significantly boosted the rowers’ immune systems. The placebo group had increased Treg counts and decreased Tδγ counts after their workouts, as is typically. But the spirulina group did not experience these immune system losses after their workouts. The researchers stated:

“The results of this study imply that supplementation with spirulina extract may protect athletes against a deficit in immune function (especially, anti-infectious function) associated with strenuous exercise, and may cause a beneficial shift in “overtraining threshold” preventing a radical deterioration of immunity.”

HIV/AIDS and immunity

Keeping the immune system sharp is an important factor when it comes to those who have been infected with HIV. HIV and AIDS infections continue to plague modern society. The human immunodeficiency virus – also called HIV – decimates the body’s immune system by hijacking the very immune cells that typically fight viral infections.

Yet research focus has gone into antiretroviral medications because these offer the biggest return for pharmaceutical companies and their funding research. And today, one of the central strategies for preventing or delaying the onslaught of AIDS among those infected with HIV is antiretroviral therapy.

Antiretroviral therapy means to reduce a virus’ expansion and replication within the body by boosting the immune system. This is typically done in conventional medicine using antiretroviral medications to try to stop the process of DNA replication among cells that have been infected with the HIV virus. Here is an illustration of the process, courtesy of AIDS InfoNet:

As it replicates, the HIV virus will essentially highjack CD4 T-cells in order to transport the virus into cells. It does this by using the CD4+ receptors that lie on the surface of cells – as our cells allow the normal attachment of CD4 T-cells.

Multinucleated syncytia: T-cell conglomeration

As the virus replicates using CD4 T-cells, it will enlist uninfected CD4 T-cells and combine them into what is called multinucleated syncytia. A multinucleated syncytia is basically a conglomeration of cells into one big collective. The formation of these conglomeration CD4 T-cells have the effect of reducing the body’s supply of these important T-cells.

And here’s the thing: These CD4 T-cells, when there are enough of them – will basically stop a virus in its tracks, preventing it from getting inside cells and replicating itself within the cells.

This is nature’s course. As long as the body is producing additional CD4 T-cells, it should be able to keep viruses from replicating. This is how the body can fight any number of viruses.

Antiretroviral drugs

Nonetheless, antiretroviral drugs have been shown to successfully interfere with the replication process once the virus has gotten into cells. This helps slow down the growth of a virus, naturally freeing up more CD4 T-cells to fight the virus.

Our body’s own CD4 T-cells can stop a virus dead in its tracks.

But ATV therapy is not the only means to increase CD4 T-cell counts. We have covered a number of natural therapies proven to stimulate T-cell counts as well as damage viruses on this site.

Now let’s examine a natural means to boost immunity and help the body produce CD4 T-cells: spirulina.

Spirulina boosts Immunity for those with HIV

Research from the Institute of Nutritional Sciences at Germany’s University of Giessen studied 73 women who were infected with HIV. The women were all from Cameroon, a sub-Sahara African country.

The researchers divided the patients into two groups. For three months, one group was given five grams per day of Arthrospira platensis – also known as spirulina or Spirulina platensis. The other group was given a placebo supplement. To eliminate possible effects of the nutrients within spirulina, the placebo supplement had a comparable nutritional makeup as spirulina – an equal amount of protein and so forth.

Before and after the 90 days, the patients were tested for CD4 T-cell counts. They also measured “viral load” – the level of viral infection in the body – and another type of T-cell, the CD8 T-cell, which expresses the cytokine CD38. This T-cell is best when it is decreased.

The researchers also measured antioxidant activity within the blood of the patients, and kidney function. The later was measured with creatinine, urea and kidney filtration rates.

After the 90 days treatment, both groups showed weight increase due to the extra protein intake, but the spirulina group showed more weight gain – a good thing for an infection that tends to waste the body.

The spirulina group also experienced no accompanying infections, while the placebo group experienced three infections during the test period.

During the treatment, the spirulina group also experienced nearly half of the associated events of HIV infection – such as liver and kidney conditions. Of the placebo group, 70 percent (21 of 30) experienced events related to HIV and among the spirulina group only 43 percent of the patients – 12 of 28 experienced associated HIV events.

In addition, in the two weeks following the three-month treatment, 10 of the placebo group patients’ conditions had worsened to a point where they had to start antiretroviral treatment (ART). Meanwhile only three of the spirulina group was determined to require antiretroviral treatment during the two weeks after the study.

In addition, more of the placebo group had to start antiretroviral treatment during the study. This was only three total patients, but it is useful to consider.

Spirulina boosts antioxidant status

The spirulina group also had a significantly higher antioxidant status in the bloodstream. Their antioxidant levels were measured with what is called total antioxidant capacity of the serum (TAOS). The TAOS levels of the placebo group went down from 357 to 336 (-22), and in the spirulina group the TAOS levels went up from 330 to 387 (up by 56).

Meanwhile, blood creatinine levels decreased significantly (a good thing) in the spirulina group – by an average of 7.31. Meanwhile, creatinine levels went up for the placebo group by .01.

While the CD4 T-cell counts did not increase for either group – as these were growing infections, with only a three-month treatment window – the spirulina group showed a smaller reduction of CD4 T-cells than the placebo group. The relative difference was .61 for the spirulina group versus .67 for the placebo group. Because the difference was considered small, it was termed “non-significant.”

The study also showed a greater reduction of CD8-CD38 T-cells in the spirulina group. Again this was considered non-significant, but was different nonetheless. The spirulina group’s CD8-CD38 counts r values at 0.18 verses 024 for the placebo.

In their conclusion, the researchers admitted that the doses were relatively low and the treatment period was short. This is specific to real treatment periods that often extend into the years.

Spirulina increases CD4 T-cell counts

The fact that spirulina can significantly increase CD4 T-cell counts was illustrated clearly in anther clinical study. This 2011 study treated 52 HIV-positive patients who were undernourished in Sub-Sahara Africa. Again in this study, half (26) of the patients were treated with spirulina and half were given a placebo of soybeans that matched the protein content of the spirulina. Again, the treatment period lasted three months.

Instead of a mere 5 grams of spirulina per day regardless of the patient’s weight, this study considered the weight of each patient. The dose of spirulina was 0.37 grams per kilogram of the patient’s body weight for the first month and 0.20 grams per kilo for the next two months. This was calculated to be approximately a quarter of the patients’ total protein intake.

The average body weight of the patients was 53 kilograms at the beginning of the study. This means the patients were given about 19 grams of spirulina per day during the first month and about 12 grams of spirulina during the last two months, give or take the patient’s average weight during that period.

Once again, this study showed the spirulina group gained considerable body mass and fat-free mass – critical for keeping ones health up. The difference in body mass was slightly higher in the soybean group (about 14 pounds to nearly 11 lbs). But the spirulina group had a significantly higher fat-free mass increase than the soybean group – by 92 pounds to 86 pounds.

In this study, the CD4 counts significantly increased among the spirulina group compared to the soybean group. And the viral load levels were significantly decreased in the spirulina group compared to the beginning of the study. The viral load levels for the spirulina group went down significantly more than the soybean group.

One of the main differences between the two studies is that the second study from Africa tested patients that were given antiretroviral drugs from the beginning of the study. Both the placebo group and the spirulina group took the antiretroviral drugs. As mentioned above, most of the patients were not on antiretroviral drugs, and slightly more of the placebo group started the ART therapy during the treatment period.

Yet another difference – one that should be considered carefully – is the dosage. The second trial utilized 2.5 to nearly four times the dose – and related the dose to weight rather than a flat five gram dose as in the first study. The second study used from 12 to 19 grams depending upon the patient’s weight.

Other research confirms spirulina fights HIV

A 2014 study from researchers from Cameroon’s University of Yaoundé along with Germany’s University of Giessen studied 73 women infected with HIV. The researchers found that five grams a day significantly boosted the antioxidant capacity and those taking the spirulina had 27 percent fewer associated HIV symptoms.

Another 2011 study from University of Yaounde studied 33 HIV patients who also had insulin resistance related to their HIV. The researchers found that 16 grams per day of spirulina boosted insulin sensitivity by 224 percent in eight weeks compared to 60 percent among the group taking soybean, another aid for insulin sensitivitity.

Should spirulina HIV treatment include ART therapy?

Given the unblemished safety record of spirulina, the inclusion of spirulina supplementation for HIV conditions appears obvious from these studies. But what about antiretroviral therapy?

As the two studies above are examined side by side, the treatment that combined spirulina with antiretroviral drugs did produce more CD4 T-cells. But it should also be noted that given the fact when the trial began, none of the first study’s patients needed antiretroviral drugs in the opinion of their doctors, while all of those in the second trial did. This means the patients in the first study were experiencing a different progression of the infection.

This of course means antiretroviral drugs should be determined by ones physician who is privy to the specific symptoms and diagnostic testing that would determine the progression of the infection.

As both studies show, supplementing with a sufficient amount of spirulina

Whether this means HIV patients should take antiretroviral drugs while taking spirulina is not an opinion to be presented in this or any other article. This determination should be made in consultation with ones personal physician.
