Nausea relief with selenium supplementation
This randomized, double-blind, crossover study explored how selenium impacts nausea and overall health in children and adolescents undergoing chemotherapy for leukemia, lymphomas, and solid tumors.

We noted a decrease in nausea and fatigue scores, particularly after a year of selenium supplementation in patients with solid tumors, suggesting it may alleviate some side effects of chemotherapy.

However, there were no significant changes for leukemia patients in nausea, despite improvements in fatigue and physical function. Overall, selenium supplementation shows promise in enhancing the quality of life for young cancer patients.

No adverse effects with supplement
We evaluated the effects of a novel enteral supplement rich in essential nutrients on cancer patients recovering from surgery. In a clinical trial, twenty patients received this supplement and were monitored for metabolic effects and gastrointestinal tolerance.

Interestingly, we found that the supplement was well tolerated, with no recorded adverse effects like nausea or vomiting. Additionally, nutrient levels, including selenium, showed significant improvements post-surgery, indicating effective absorption. Overall, early gut feeding using this supplement seems to be a promising strategy for cancer patients.

Sodium selenite may reduce nausea
We explored the impact of sodium selenite on nausea in brain tumor patients through a carefully designed study. The treatment involved administering sodium selenite along with other supportive therapies over a period of 4 to 8 weeks.

Notably, 76% of patients reported significant improvements, including reductions in nausea and other troubling symptoms. Additionally, patients showed better overall health markers like increased blood counts.

This suggests that sodium selenite, especially when combined with oxygen therapy, may effectively address nausea and other symptoms in this challenging patient group.

Comfortable reception
1 people found this helpful
I cautiously took selenium for an extended period. Although I was warned about its unpleasant odour causing nausea, I found that the pills barely had a smell. Thankfully, I experienced no nausea or belching, and my general condition has improved. However, I didn’t feel as invigorated as with previous selenium types. Nonetheless, it’s manageable and well tolerated by my family.

No nausea
In the initial days, this supplement was well absorbed, and I experienced no nausea or stomach issues. I recommend it for anyone seeking similar benefits.
2
Unpleasant smell
Unfortunately, I found the smell of this product unbearable. It was unlike any other I've tried and caused me nausea after just three days of use, prompting me to stop taking it.

Quality ingredients
I chose selenium for my son due to my confidence in its quality. The composition is good and the taste is neutral, making it easy for a child to take. While a high frequency can induce nausea, we take it once daily at night to maximise benefits without adverse effects. I recommend it.
7.5
Good for immunity
I trust this brand for its reliable and effective dietary supplements. Selenium helps improve my hair, skin, and nails. I follow doctor recommendations to take it with food, as taking it on an empty stomach may cause nausea. The capsules have a neutral taste and are an excellent supplement for immunity.

Stopped due to nausea
I wasn't keen on it. The quality seems good, but the tablet's round and large shape makes it uncomfortable to take. My endocrinologist prescribed Selenium as a precaution, but after about two weeks, I began to feel nausea and weakness, prompting me to stop.

Persistent nausea
It’s vital to adhere strictly to the dosage instructions. Initially, I took selenium daily despite my doctor advising a weekly intake to avoid side effects. I’ve stopped taking it now due to relentless nausea and dizziness. It's crucial to consult your GP regarding selenium use.
