Cough reduced significantly
Most Useful Review

An excellent product at a great price! This remedy significantly reduces cough and phlegm, outperforming Claritan and other over-the-counter options. I was sceptical initially, especially seeing my husband recover from a long bout of pneumonia with persistent coughing even through medication. However, after taking it, his cough diminished within a day, and he finally slept soundly in bed again. We’re committed to buying this; it has truly made a difference.

Mood and energy boost

THIS STUFF WORKS!! We both began taking it to prevent winter colds and for Seasonal Affective Disorder (SAD) prevalent in long, dark winters. We noticed a mood boost within just 2 days and felt more alert. We haven't had any colds, flu, or sinus infections this winter, when typically we'd have at least a couple of severe infections. I take 2 tablets in the morning with coffee for energy, especially before workouts. I've learned NAC is beneficial for many issues, including cold and flu prevention. I share this with my friends—it's effective!

We conducted a 12-week study to explore the effects of selenium supplementation on flu immunity in healthy adults aged 50-64. Participants were divided into groups receiving different selenium doses or no selenium at all.
The results indicated that selenium could have both positive and negative impacts on immunity against the flu vaccine, influenced by the amount and type of selenium consumed. This complexity highlights the need for careful consideration of the benefits and risks associated with selenium supplementation in boosting flu immunity.

Selenium shows promise for migraines
We explored the effects of selenium supplementation in a double-blinded trial involving 72 patients with migraines. Over 12 weeks, participants received either selenium or a placebo. We observed that those taking selenium experienced reduced headache frequency and severity.
Additionally, selenium improved antioxidant levels and lowered oxidative stress markers. However, it appears that many other factors related to migraine symptoms did not see significant changes. While this research shows promise, further studies are necessary to confirm these findings.

NAC truly benefits my OCD and social anxiety, providing better focus and creativity. It alleviates hangover headaches, which I used to experience after drinking. I can now enjoy social events without dread of the next day.

Effective for anxiety
Most Useful Review

I conducted blinded tests on this product for anxiety and it works! I experimented on myself for a month, noting which days I took NAC while my girlfriend kept track. There was a noticeable difference in my anxiety levels on days I took NAC compared to when I didn't. It appears effective for me, but it’s important to cycle it (4 days on, 2 days off) because NAC increases glutathione levels, and to maintain those levels, a break is necessary.

Our family takes NAC, which has helped my daughter with autism and her OCD behaviours significantly. Clinical studies back its efficacy for treating similar disorders. It's also handy in emergencies and has no taste, making it easy to consume.

Breathing improved
Most Useful Review

Finding NAC has been a relief. I typically suffer from sinus infections during winter, which often lead to bronchitis. This winter, I experienced intense phlegm and struggled with athletic activities. I found NAC online and took 2 x 600mg for six days, which resulted in clear breathing and normalised sinuses. My doctor supports continuing NAC as a preventative measure against future lung issues. It really works, while Mucinex proved ineffective for me.

Cough relief
Most Useful Review

Excellent product and great price! It reduces cough and phlegm better than Claritin or any other product. My husband, recovering from a long bout of pneumonia, was constantly coughing. Despite using codeine cough syrup, he found no relief. After starting this product, his cough lessened significantly, and he slept well for the first time in ages. I am sold on NAC, especially given the much better price on Amazon compared to health food stores.

We examined how selenium, a trace element known for its role in health, can help those suffering from allergic dermatitis. In our exploration, we focused on how selenium nanoparticles, specifically designed for easier manufacturing and use, can activate the body's natural defenses against allergies.
The study highlighted how selenium impacts allergic reactions by enhancing the production of selenoproteins, which are crucial in regulating inflammation and oxidative stress. We saw that these selenium nanoparticles effectively inhibited mast cell activation. Mast cells are known to release substances that can trigger allergic reactions, so by reducing their activation, the potential for severe allergic responses decreased.
Additionally, through a series of experiments on allergic mouse models, we confirmed the nanoparticles increased selenium levels in the skin, which led to a reduction in inflammatory cells and mast cell activation. The results indicated significant therapeutic benefits, providing a promising avenue for managing allergic reactions.
Ultimately, this study not only demonstrates the innovative use of selenium nanoparticles in treating allergies but also emphasizes the importance of scaling up their production for broader clinical application.

Eases sinus congestion
Most Useful Review

Alleviates sinus congestion and boosts the immune system. I've been intermittently taking N-A-C for over three years, and it's significantly helped alleviate sinus congestion and improve lung capacity. N-A-C enhances our body's supply of Glutathione, crucial for maintaining antioxidant defences. The boost of Glutathione noticeably reduces my sinus congestion during allergy season. Within days of starting the supplement, I breathe easier, especially with dust allergies. I notice I can jog and play soccer without difficulty, improving my stamina.

Selenium nanoparticles reduce liver toxicity
We investigated how selenium nanoparticles (Se-NPs) and chitosan-encapsulated selenium nanoparticles (Se-CS-NPs) can mitigate liver toxicity induced by carbon tetrachloride (CCl) in rats. In our study, eighty rats were divided into eight groups, including placebo and control.
The findings indicated that both forms of selenium helped in reducing liver damage by influencing key biological markers. Notably, while selenium was effective, encapsulating it with chitosan did not provide additional benefits. Overall, these nanoparticles could be a valuable treatment option against liver toxicity.

Restores liver health

I've relied on this for 15 years, recommending it widely for liver repair and restoration. My son reversed his fatty liver disease within months. We never faced the reported "spotting" issues, and I appreciate the natural sulphur smell, indicating glutathione production by the liver. Despite its age, I trust its quality and find it effective for maintaining liver health.

This study explored how selenium intake relates to lung function in people with asthma. We analyzed data from 4,541 participants in a national survey using various statistical methods. Our findings showed a positive connection between higher selenium intake and better lung function, particularly in forced vital capacity and forced expiratory volume. We noted that to potentially enhance respiratory health, asthma patients could benefit from consuming between 137.65 mcg and 200 mcg of selenium daily, while also being cautious of any adverse effects.

I’ve recently struggled with sinus issues and asthma-like symptoms, leading to anxiety attacks. I bought this thinking it was just a molybdenum supplement, but within an hour my breathing improved significantly. This product has offered the relief I couldn’t find with previous treatments, bringing my symptoms to mild levels.

Selenium showed no significant effects
We examined a clinical trial that investigates whether selenium supplementation can help alleviate migraine symptoms. In this randomized, double-blinded study, 72 patients were divided into two groups: one received a daily selenium supplement while the other got a placebo, all over 12 weeks.
We tracked headache severity, frequency, and mental health markers like anxiety and depression, alongside measuring oxidative stress biomarkers. Despite the hopes for selenium’s antioxidant benefits, the trial did not find significant improvements in migraine symptoms or related health measures.

This is a miracle supplement! I have chronic inflammatory issues and have tried countless remedies since 2013 with no success. Since taking this along with L-glutamine, my migraine symptoms are virtually gone, and my energy and mood have improved significantly.
