When given to animals, Spirulina increased antioxidants and reduced tumor growth.
It caused changes at the cellular level, promoting cancer cell death and impacting key growth pathways.
The study identified several compounds in Spirulina that target specific proteins, suggesting it could play a significant role in breast cancer treatment.

Spirulina shows promise in PDT
We explored the efficacy of a new cubic form of spirulina (CSP) in photodynamic therapy (PDT) for cancer treatment. In our study using tongue cancer cells, we compared CSP with its naturally occurring counterpart and another photosensitizer.
All three showed safety for normal cells, but while CSP and the natural form mainly caused apoptotic cell death, the other led to necrosis. We found that CSP is a promising option for cancer PDT, although caution is advised with higher concentrations of the other photosensitizer due to toxicity concerns.

We examined how C-phycocyanin (C-PC) impacts melanoma, a particularly aggressive skin cancer. In our study, we induced tumors in mice and subsequently treated them with C-PC for three days. We found that treatment boosted key immune cells and showed significant immunomodulatory effects, especially when tumors were present. Importantly, there was no damage to vital organs from the treatment. Our research highlights the potential role of C-PC in enhancing tumor immunity, suggesting promising avenues for future clinical trials in cancer treatment.

Organic Spirulina Powder is a fantastic supplement I've been ordering frequently. This superfood offers several benefits including reducing fatigue, improving mood, lowering cholesterol and blood glucose levels, and exhibiting antioxidant properties that help in the fight against cancer. It protects the brain, lessens allergy activity, and enhances kidney and liver function. Notably, it contains considerable amounts of Vitamin A and B-12, with no GMOs. However, there are contraindications for those allergic to seafood or iodine, pregnant women, and others with specific health conditions. Based on my experience, I take one teaspoon daily, preferably before meals, mixed with water. Although the taste took some getting used to, I truly enjoy the energy boost and improved mood it provides. A healthy lifestyle is still vital for the best results alongside spirulina.

We explored the anticancer potential of Spirulina maxima extract, particularly through a new delivery method called nanoemulsion. This approach effectively loaded the extract into tiny nanoparticles, making it more stable.
Our findings showed that this treatment significantly reduced cell viability in cancer cell lines and successfully inhibited tumor growth in mice. Notably, the treatment also normalized liver enzymes and decreased oxidative stress.
While the results are promising, it's essential to note that more research is needed to fully understand its effectiveness in cancer treatment.

Spirulina aids in testicular protection
We examined the potential of nano Spirulina platensis (NSP) to protect rat testicles from cisplatin-induced damage, a common chemotherapy drug. In a controlled study with groups receiving different treatments, we found that NSP significantly improved sperm quality, hormone levels, and overall testicular health compared to those receiving cisplatin alone. Notably, NSP also enhanced the expression of key genes involved in reproductive health. This suggests that NSP could be a beneficial support for mitigating the harmful effects of cisplatin on fertility.

We investigated an innovative system using Spirulina platensis and gold nanoclusters to enhance cancer radiotherapy. This approach is designed to work through several mechanisms, including producing oxygen when exposed to light.
The system effectively generates reactive oxygen species that can attack tumor cells and improve the sensitivity of radiation treatment. In studies with two cancer models, the results showed significant improvements in tumor reduction compared to standard treatments.
While promising, this research is still in its early phases, so further exploration is necessary to fully understand its potential in real-world applications.

Spirulina fermentation reduces cancer cell viability
We looked into how fermented Spirulina, produced under optimized conditions with specific bacteria and yeast, affects cancer treatment. In our testing, a unique production mode significantly reduced the viability of colon cancer cells by up to 72% without harming normal cell function.
This indicates that fermented Spirulina has potential as a supplementary food source with beneficial properties, particularly for cancer support. However, more research is needed to truly understand its bioactive compounds and their impact on human health.

Spirulina proteins show anticancer promise
We explored a novel technique to extract antioxidants and anticancer proteins from spirulina, a cyanobacterial biomass known for its beneficial properties. This method utilized ultrasound-assisted deep eutectic solvent extraction, optimizing extraction parameters to maximize protein yield and bioactivity.
Our findings revealed a protein yield of over 80% with impressive antioxidant capabilities. Notably, the extracted proteins showed significant cytotoxic effects against colorectal cancer cells while being safe for normal cells. This highlights spirulina’s potential as a natural ally in cancer treatment and health enhancement.

We investigated a new treatment using Spirulina platensis as an innovative embolic agent for tackling hepatocellular carcinoma (HCC). This microalgae formulation, loaded with doxorubicin, was designed to overcome challenges with current therapies by improving drug delivery and maintaining effectiveness in challenging tumor environments.
The treatment not only showed success in reducing tumor size in rat models but did so with minimal side effects due to the natural safety profile of Spirulina. These promising results suggest that DOX-SP may offer a viable solution for improving cancer treatment strategies in HCC.

We investigated the potential of selenium nanoparticles (SP-SeNPs) sourced from Spirulina platensis in treating cancer. The results showed that these nanoparticles not only possess antioxidant and antimicrobial properties but also demonstrated anti-tumor effects.
In experiments with breast and ovarian cancer cell lines, we observed a reduction in cell viability, indicating their potential in cancer therapies. While SP-SeNPs show promise, further studies are essential to fully understand their effectiveness and applications in medical treatment.
