Research finds Chlorella extract effective against Heavy metal toxicity

It will not be wrong at all if we say “everything on this planet is now adulterated, nutrient-deficient, dirtied, and contaminated.” Our food industry has fallen prey to the present, corrupt and heavy-handed political system. The authorities don’t bother to care about the health of the state at all.

However, some organic farmers, natural health professionals, and a few leaders still serve as a silver lining of the cloud! They are standing up to the corruption, creating a movement that invests in nourishing and sustainable practices. They aim at harnessing potent foods from nature that may serve as a solution to the toxic and malnourished food destroying people’s quality of life.

Scientists along with their tireless, effortless, and extensive research have come along with a long list which enumerates the finest and the most potent foods on planet Earth. To your great surprise, Chlorella is among the top of such food choices.

Research declares Chlorella to be densed with nutrients that fight off our major corporal, health problems including “Heavy metal toxicity” especially.

What is Chlorella?

Before getting into the nutritious details regarding the food let’s find out what exactly Chlorella is?
Chlorella is a nutrient-dense, single-celled, green, freshwater alga. Moreover, it is also available as a supplement. It has shown promising effects in improving the levels of cholesterol and removing toxins from the body.

There are over 30 different species of Chlorella. However, only two types are most commonly used in research i.e.

  • Chlorella vulgaris
  • Chlorella pyrenoidosa

Chlorella has a hard cell wall that humans cannot digest. Thus, it must be taken as a supplement to reap its benefits. It’s accessible in capsule, tablet, powder, and extract form as well. Apart from serving as a nutritional supplement, Chlorella is also used as a bio-diesel fuel.

Nutrients found in Chlorella

Chlorella has an amazingly impressive nutritional profile. These nutrients may vary from species to species. Moreover, the growing conditions of the species also affect the nutrient levels of the alga. Following are the nutrients found in Chlorella,

It has 50–60% of protein. It serves as a complete protein source, containing all nine essential amino acids.

Chlorella is a potent source of iron. It may provide from 6 to 40% of your daily irons need. Moreover, it’s rich in vitamin C, which helps you to absorb iron. Some Chlorella varieties may also contain vitamin B12.

These tiny green cells pack a wide range of antioxidants. They also contain small amounts of magnesium, zinc, copper, potassium, calcium, folic acid, and other B vitamins. Chlorella also contains Omega-3 fatty acids. Around 3 grams of Chlorella delivers 100 mg of omega-3 fatty acids.

The respective alga presents a good source of fiber. However, most of the supplements don’t provide even 1 gram of fiber per dose.

Chlorella aids Detoxification of our body

Several studies demonstrate Chlorella to be a potential detoxifier for a living body. It protects the individual against toxicity caused by heavy metals’ accumulation. Studies validate the effectiveness of Chlorella at helping remove heavy metals like methyl-mercury and lead etc.

People usually get exposed to such heavy metals through pollution, certain jobs such as mining, fish, mercury amalgams, and vaccination etc. Chlorella weakens the heavy metal toxicity of the liver, brain, and kidneys.

A study, published in the Journal of International Immunopharmacology, enumerates the protective effects of Chlorella vulgaris in mice exposed to lead.

The study examined Chlorella vulgaris extract (CVE) for its chelating effects on the myelosuppression induced by lead in mice infected with Listeria monocytogenes. For the experimental study, the researchers employed two groups of mice,

  1. One infected with Listeria monocytogenes only
  2. The other was infected with L.monocytogenes and then exposed to lead

Lead exposure after an infection caused a severe reduction in the number of bone marrow granulocyte-macrophage progenitors (CFU-GM). The reduction produced by the infection was further potentiated by lead exposure. However, extramedullary hematopoiesis, which was drastically increased after the infection, was not altered by the presence of lead.

Researchers noted the levels of lead in the blood of the mice, to test the efficacy of the extract. It was observed that CVE extract simultaneously given with lead exposure caused a dramatic reduction of 66.03% in blood lead levels. On the other hand, CVE treatment after 3-10 days of the exposure produced a much less effective chelating effect. It caused a reduction in blood lead levels by 13.5% to 17% only.

The efficacy of the extract was further challenged. After a 10-day treatment with 50 mg/kg of CVE per day, the infected and infected/lead-exposed mice were challenged with a lethal dose of L. monocytogenes. The researchers observed 30% survival rates for the infected group and 20% for the infected/lead-exposed group.

The notable better response observed with the simultaneous CVE/lead administration indicates that the immune-modulation effect of CVE plays an eminent role in the capacity of this alga to trim down blood lead levels.

Other studies validating the fact

Another study published in the Journal of Toxicological Sciences enumerates the effect of Chlorella consumption on the elimination of methyl-mercury (MeHg).

The investigators employed 10 weeks aged C57BL/6N female mice for the study. The mice were orally administered with 5 mg/kg of MeHg chloride. The researchers investigated the influence of Chlorella on the excretion and tissue accumulation of methylmercury (MeHg). To serve the purpose, they provided the mice with diets containing 0%, 5%, or 10% Parachlorella beijerinckii powder (BP). The mice were then housed in metabolism cages. Their urine and feces were collected for 3 weeks.

The results showed lower blood Hg levels in the 5% and 10% BP-fed groups within 7 days. However, the control group, fed with 0% BP, showed no plausible effects.

During the 21 days of experimentation, notable increases in the growing mercury eliminations into the urine (5% BP) and feces (5% and 10% BP) were found in the BP groups. After Twenty-one days, the organ levels of Hg in both BP groups tended to decrease significantly as well. The reduction of Hg levels wasn’t significant in the liver. However, kidney and brain marked a considerable decrease in Hg levels.

These results suggest that a continuous intake of BP accelerates the excretion of MeHg. It subsequently decreases tissue Hg levels in mice without altering the glutathione (GSH) metabolism. Further studies and researches are encouraged to reveal details regarding the mechanism of BP-induced development of MeHg excretion.

Chlorella is a powerful alkaline-forming food. It is rich in chlorophyll. This pigment makes the plant appear green, healthy, and therapeutically beneficial for the well-being of the consumer. Chlorella is full of enzymes, phytonutrients, especially, essential fatty acids like gamma linoleic acid. It’s rich in dietary nucleic acids like RNA and DNA as well.

Adding in this kind of nutrition in your body can help you absorb more synergistic nutrients and healing power as compared to any other supplement. When you consume “clean” Chlorella every day, you’re giving your body an open, healthy access to optimize different bodily processes.
