Aug 4, 2019 · What’s more, spirulina growing in waters with high concentrations of mercury and lead absorbs these heavy metals. In addition to liver damage, contaminated spirulina can cause nausea, vomiting, weakness, rapid heartbeat, shock and death.

Metals like lead, mercury, cadmium, and arsenic are the most likely to adulterate Spirulina products. Each is found as a trace contaminant in certain pesticides and fertilizers, so they are common in agricultural areas.

Also known as blue-green algae, spirulina is a plant-based superfood with anti-inflammatory properties that support the body while detoxing heavy metals. (16) Spirulina can also reduce oxidative damage in the brain, according to animal studies.

A total of 58 preclinical studies demonstrate the alleviative effect of Spirulina against experimental arsenic, cadmium, lead, and mercury toxicities. Five clinical studies reported protective effects of Spirulina against arsenic toxicity in humans.

Jan 23, 2020 · Spirulina may be tainted with microbes, radioactive metal ions and heavy metals — including mercury, cadmium, lead and arsenic. Harvard Health Publishing adds that spirulina, like other dietary supplements, is not regulated by the FDA.

Sep 12, 2024 · To our surprise, we learned that spirulina often contains high traces of heavy metals. We decided to check the market and purchased best-selling spirulina products from Amazon. To our astonishment, the products purchased from Amazon contained arsenic, lead, cadmium, and mercury.

Apr 13, 2014 · Researchers with the University of Rjasthan, India, say Spirulina fusiformis is able to not only protect the kidneys, but may also be able to reverse the damage done by toxic mercury. Published in the journal Food Chemistry Toxicology, the study separated albino mice into four groups.

Spirulina, a filamentous microalga, is used all over the world as a nutraceutical dietary supplement. Recent studies have focused on examining its chelating activity and antioxidant properties, especially as a candidate for protection against neurotoxicity caused by heavy metals.

Jun 13, 2022 · The present study investigated the ability of blue-green algae ‘ Spirulina’ (Arthrospira platensis) to bind with mercury at different pH conditions, i.e., water, SGF (pH 1.2) and SIF (pH 6.8) to simulate the conditions of gastrointestinal pH.

Jun 13, 2022 · In mice, Spirulina and activated charcoal were significantly reduced the mercury deposition in tissues and facilitated their excretion through feces. Spirulina has shown good adsorption and removal efficacy like activated charcoal.
