Based on 15 Researches

Upadhyay TK, Trivedi R, Khan F, Al-Keridis LA, Pandey P, et al. elucidation of antioxidant, antiproliferative, and apoptotic potential of yeast-derived β-1,3-glucan particles against cervical cancer cells. Front Oncol. 2022;12:942075. doi:10.3389/fonc.2022.942075

We examined how yeast-derived beta glucan could potentially assist in treating cervical cancer. Our study involved thorough testing to evaluate its effects on cancer cells, revealing that beta glucan generates reactive oxygen species, which can lead to cell apoptosis. We discovered that this substance effectively slows down the growth of cervical cancer cells at specific concentrations.

While these findings are promising, they indicate that further research is essential to fully understand its anticancer properties and potential as a safer alternative therapy alongside traditional treatments.

Helps me long-term in my battle against cancer. I wasn't aware of this product until my doctor recommended it after viewing my immune analysis, showing deficiencies in T-helpers and natural killers. Since I’m undergoing chemotherapy, I've needed support. I started taking this in 2018, and the effects are noticeable: stomatitis and skin fungi from chemotherapy have resolved. Most importantly, there is some stability in my underlying condition (sarcoma). I chose not to buy this last year, and within three months, I noticed a downturn. Hence, I’ve resolved to continue taking this for life, as it clearly has a positive effect!

I remember the dread of winter approaching, knowing it would bring an endless cycle of illnesses for our children. They perpetually passed infections amongst themselves, often resulting in high temperatures and dreadful coughs that required antibiotics. This exhausting cycle ended with the discovery of EpiCor and beta glucans, which truly work! At the first sign of malaise, I gave each child a capsule, and generally, the illness didn’t progress further. Even when symptoms lingered, they were significantly milder, and we managed to avoid antibiotics. This isn't the only antiviral I use, but it's one of the best. I've tried various brands, and while they all work well, I was particularly drawn to this one labelled "Extra Strength," which boasts an additional immune-boosting larch extract. I believe this blend significantly enhances immune response.

My mother, aged 73 and an asthmatic, has long struggled with various winter health issues and seasonal allergies. I started her on NOW Foods beta glucans (100mg) two and a half years ago, and since then, she hasn't had a cold or flu. I recently increased her dosage to 250mg out of precaution due to COVID-19, and she remains in perfect health, even venturing out in public. Additionally, her blood sugar and cholesterol have returned to normal, ostensibly due to the beta glucans. This regime has also contributed to her weight loss. Beta glucans have had a remarkable effect on her immunity, effectively preventing bouts of food poisoning.

Calegari GC, Barboza MGL, Dyna AL, Barbosa-Dekker AM, Dekker RFH, et al. Structural relationship of regioselectively-sulfonated botryosphaeran derivatives on activity against herpes simplex virus type 1. Int J Biol Macromol. 2024;274:133261. doi:10.1016/j.ijbiomac.2024.133261

We examined the effects of sulfonated derivatives of a natural polysaccharide, botryosphaeran, on the herpes virus, specifically HSV-1. Two different sulfonation methods yielded derivatives with varying effectiveness. The one treated with mild sulfonation showed significant antiviral activity, successfully inhibiting HSV-1, while the other approach did not demonstrate any effectiveness.

This suggests that the placement of sulfate groups is crucial for attacking herpes. Despite the success with HSV-1, neither derivative worked against dengue virus, revealing a targeted action specific to herpes.
