Hydrothermal yeast impacts breast cancer
We investigated the ability of a hydrothermally treated yeast cell wall to fight against MCF-7 breast cancer cells. This innovative method improved solubility and produced a potent anti-proliferative agent.

The treatment significantly reduced cancer cell growth by nearly 59%, even when separated by a plastic barrier.

This suggests that a diffusible factor in the treated yeast contributes to this anti-cancer effect, likely linked to reactive carbon species generated during treatment.

Overall, our findings hint at a promising potential for this approach in cancer therapy development.

Engineered yeast for cancer therapy
We explored an innovative system using Saccharomyces cerevisiae var. boulardii that secretes immune checkpoint inhibitors. This method has shown promise in reducing intestinal tumor loads, presenting a potential breakthrough in cancer immunotherapy.

The study highlights the engineered yeast's ability to safely deliver biologics, enhancing their effectiveness. While it’s still early days, the potential for such treatments could change how we approach cancer treatment in the future.

Engineered yeast protects heart health
We investigated the effects of engineered yeast that produces butyrate on heart damage caused by cancer radiotherapy. This study demonstrated that the yeast assists in maintaining intestinal health, which in turn significantly reduces heart tissue damage during radiation treatment.

By increasing beneficial gut bacteria and activating certain genes, the engineered yeast helps mitigate the harsh side effects of radiotherapy. This brings a promising avenue for improving cancer treatment and protecting vital organs, ultimately enhancing patient care.

Beta glucan offers good value and quality. It has been known for over 50 years for its healing properties, particularly for cancer, which is my reason for taking it. It also helps against conditions like high cholesterol, diabetes, and reduces the side effects of radiation and chemotherapy. Recently, production costs have decreased, making it more accessible. This NOW brand offers a 500 mg dose per capsule at a much lower cost, making it a better option compared to more expensive alternatives.

Helps me for a long time in the fight against cancer. I discovered this product through my doctor after a detailed immune analysis showed deficiencies. As I'm undergoing chemotherapy, I need to support my body. Since I began taking this in 2018, I’ve seen results: stomatitis and dermatophytosis have disappeared. Most importantly, there is some stability in my underlying disease (sarcoma). Last year, I paused the medication, and in three months, I noticed a negative trend. Ultimately, I've decided to continue this medication for my lifetime as I can clearly see the benefits!

Beta glucan significantly enhances the immune system and is beneficial for skin health. My wife had colorectal cancer and underwent 30 days of radiation. When her doctor examined her, he was astonished at her condition; her insides appeared remarkably healthy. Upon learning she was taking Beta Glucan, he advised her to continue for the rest of her life. Thank you, Now and iHerb!

Cancer-targeting yeast technology
We explored a new treatment mechanism using a formulation called LYTAC that employs glyco-engineered yeast-derived glycans for targeting cancer cells. This method taps into the body’s natural lysosomal degradation system to remove a protein linked to tumors.

In our study, LYTAC demonstrated the ability to effectively degrade the PD-L1 protein, which is known to inhibit T cell activity against cancer. Not only did it show greater effectiveness compared to traditional treatments, but it also highlights an innovative approach that could play a vital role in advancing cancer therapies.

Since my cervical cancer dysplasia diagnosis, I have taken this alongside AHCC without fail. Initially, I hoped to boost my immunity, and I believe it also improves my intestinal health, leading to regular bowel movements, unless stressed. Although the capsules are somewhat larger, I find them easy to swallow without any unpleasant taste.

Strengthens immune system
6 people found this helpful
Very effective! I have taken Beta Glucans for over 10 years now. It significantly strengthens my immune system by increasing the percentage of lymphocytes (T cells and B cells), crucial for tackling viruses and cancer cells. Now Foods Beta Glucans is one of the top brands and quite affordable. I take one capsule 2-3 times a day on an empty stomach. For healthy individuals, one capsule daily is usually sufficient.

Helps prevent cervical cancer
1 people found this helpful
I started taking this to inactivate HPV and prevent cervical cancer. I consume 2 tablets each morning on an empty stomach, then 2 before bed, totalling 4 daily. I find the combination with AHCC particularly beneficial. As my immunity improves, I'm hopeful that it will not only deactivate HPV but also prevent other diseases, alongside improving the health of my skin.
