Aphanizomenon flos-aquae (AFA) is a nutrient-dense cyanobacterium, or blue-green algae, and one of the most complete and balanced whole foods available. This microscopic organism is used to create AFA extract, a dietary supplement celebrated for its high concentration of vitamins, minerals, and other bioactive compounds.

Spirulina, a blue-green algae, is often touted as a superfood, yet certain individuals should avoid it. Understanding these contraindications is crucial before including it in your diet or supplement regimen.

According to a 2023 study, microplastic fragments were found in commercially available spirulina products, highlighting a growing environmental risk. Beyond plastics, what is the contamination in spirulina that consumers should be aware of? Common issues include heavy metals, cyanotoxins, and pathogenic bacteria that can compromise the safety of this popular supplement.

Some varieties of blue-green algae, scientifically known as cyanobacteria, produce toxins that can be extremely harmful to humans, pets, and livestock. Exposure to these toxins, especially during dense algal blooms, can lead to a range of mild to life-threatening side effects, including severe gastrointestinal distress, skin irritation, and even liver or nervous system damage.

According to a 2025 review of scientific literature, spirulina products have been found to contain varying levels of microcystin toxins, highlighting the critical importance of careful product selection. When adding this powerful superfood to your routine, quality should always be your top priority to ensure safety and maximize health benefits.

Overconsumption of poorly sourced spirulina, a blue-green algae, can lead to serious health issues, including liver damage from toxins. While widely considered a superfood, it is vital to understand the potential negative effects before adding it to your routine and to know the answer to, 'Does spirulina have any side effects?'

According to the World Health Organization, toxins produced by algae in both fresh and salt water can pose a serious threat to human health, causing symptoms from stomachaches and diarrhea to severe neurological effects and even death. While not all algae are dangerous, a specific type known as harmful algal blooms (HABs) can contaminate food sources through various pathways, creating significant health risks.

Studies have shown that spirulina has the potential to absorb and accumulate heavy metals from its growing environment, a capacity sometimes utilized for bioremediation. This ability means that the safety of spirulina as a dietary supplement hinges entirely on its cultivation and sourcing methods. Consumers must be diligent to ensure they purchase a product free from harmful contaminants.

According to scientific studies, spirulina harvested in the wild or cultivated in open ponds is susceptible to contamination from heavy metals and other toxins present in its growing environment. Understanding what is the contamination of spirulina powder is crucial for ensuring the safety and purity of this popular dietary supplement.

Spirulina, a type of blue-green algae, is a popular dietary supplement, but concerns about its safety persist. Research shows that contaminated spirulina can be toxic to humans.
