Selenium supports cholesterol management
We investigated how selenium supplementation affects cholesterol levels and the associated molecular changes. Using Sprague-Dawley male rats, we fed them diets supplemented with selenium alongside high cholesterol for three months.

The results showed that while apolipoprotein B levels rose with the cholesterol diet, supplementing with 1 ppm of selenium significantly reduced these levels. Additionally, the expression of HMG-CoA reductase also decreased with selenium supplementation.

Overall, our findings suggest that selenium could offer a supportive role in managing lipid metabolism and high cholesterol.

Potential atheroprotective effects of T3
We aimed to explore how pure tocotrienol (T3), a form of vitamin E, might help in fighting atherosclerosis, a condition often linked to high cholesterol. In our study, 30 rabbits were fed high-cholesterol diets and then divided into groups receiving different doses of T3 or a control without T3.

The results were promising, showing that the lower and higher doses of T3 significantly reduced atherosclerotic markers and inflammation in early and established atherosclerosis compared to the control group. This suggests that T3 may play a valuable role alongside standard treatments in preventing coronary artery disease.

Selenium nanoparticles show limited effectiveness
We investigated whether selenium nanoparticles (SeNPs) could combat atherosclerosis related to high cholesterol. In our study involving apolipoprotein E deficient mice on a high-fat diet, both BSA- and chitosan-coated SeNPs showed promise in reducing atherosclerotic lesions over 12 weeks.

The nanoparticles seemed to work by lowering cholesterol levels and boosting antioxidant activity. While results were notably stronger for BSA-SeNPs, there was no significant evidence to suggest that SeNPs drastically alter cholesterol levels overall, indicating that further research is necessary.

Two years ago, I found I was selenium deficient. Selenium is a super antioxidant that aids thyroid hormone production, crucial for maintenance of function. I found this selenium supplement with 200 micrograms, taking one capsule daily. After two years, my selenium levels are now normal, which brings me great happiness. I highly recommend this high-quality selenium.

Improved thyroid function
4 people found this helpful
I recommend this high-quality complex. Selenium is crucial for the thyroid gland, activating thyroxine. It also improves iodine absorption and protects the thyroid from free radical damage, combating hypothyroidism. With vitamin E, the absorption is significantly enhanced. I once reduced my dose of euthyrox from 100 to 50, which shows its effectiveness. The capsules are easily swallowed, and the results have been significant for me.

Selenium nanoparticles reduce cholesterol
We explored the effects of selenium nanoparticles on high cholesterol by studying ApoE-deficient mice on a high-fat diet. Over eight weeks, we noted that selenium nanoparticles significantly reduced total cholesterol and triglycerides while boosting beneficial HDL levels.

Additionally, these nanoparticles improved vascular health and regulated important genes for cholesterol metabolism while enhancing antioxidant enzyme activities. However, it's important to note that while the results were promising in mice, the findings do not directly translate to humans yet.

Selenium may help cholesterol levels
We investigated the effects of selenium supplementation on LDL receptor activity and mRNA expression in male rats with high cholesterol. The study involved feeding the rats diets with varying selenium levels along with a high-cholesterol diet over three months.

Our results showed that while high cholesterol reduced both LDL receptor activity and mRNA expression, selenium at 1 ppm effectively improved these measures. This suggests that selenium may play a positive role in managing cholesterol levels and supporting lipid metabolism.

Selenium reduces cholesterol in rats
We explored how selenium affects lipid levels in rats consuming a high-cholesterol diet over ten weeks. By comparing selenium-treated groups with control rats, we found that selenium effectively reduced triglycerides, total cholesterol, and low-density lipoprotein cholesterol.

Additionally, it inhibited liver fat accumulation. These findings suggest that selenium could play a beneficial, recuperative role against high cholesterol. However, it's important to note that this research is based on animal studies, so human applicability requires further investigation.

Selenium is best absorbed with vitamin E, thus purchasing both together is recommended. It is essential for treating conditions like arrhythmia, coronary heart disease, hypertension, and atherosclerosis, and helps normalise fat metabolism and blood cholesterol levels. It protects blood vessels and heart muscle while reducing hypertension risk. An excellent supplement with a superb composition!

Medical necessity recommended
1 people found this helpful
Due to high antibody levels, my endocrinologist recommended a substantial selenium dosage. After two months of regular usage, my antibody levels indeed decreased. I advise against indiscriminate consumption; it's best for those with legitimate medical needs, while lower dosages are suitable for prevention. Avoid taking it continuously beyond three months; breaks are necessary.

I bought selenium from iHerb on my friend's recommendation, as I heard that centenarians have high levels of healthy minerals, including selenium. This Selenium Super Complex contains three forms of selenium plus vitamin E for good health. I found it beneficial, particularly as menopause brought hot flashes. After using this complex, symptoms like hot flashes and weakness vanished. I realised this complex aids the body in combatting oxidative damage. You only need to take it once a day, with 100 capsules in a jar lasting three months.

GlcSeCys reduces obesity, cholesterol
We explored the effects of a novel selenoglycoside compound, GlcSeCys, on obesity and high cholesterol in mice fed a high-fat, high-cholesterol diet. This compound demonstrated significant benefits, including reduced fat accumulation and improved blood sugar levels.

We observed that GlcSeCys works by inhibiting fat production in the liver and reducing inflammation, while also supporting healthy fat tissue function. This study highlights GlcSeCys as a potential new approach for treating obesity and metabolic disorders linked to high cholesterol.

Brazil nuts reduce cholesterol levels
We explored the effects of incorporating Brazil nut flour into the diets of dyslipidemic and hypertensive patients. In a randomized, double-blind study, 77 patients already taking lipid-lowering medications were given either Brazil nut flour or a placebo over 90 days.

Those consuming the Brazil nut flour showed significant reductions in total cholesterol and non-HDL cholesterol levels, suggesting a positive impact on cholesterol management. However, there were no notable differences in blood pressure or overall serum lipids between the two groups.

While the Brazil nuts appear beneficial, more research is needed to fully understand these effects.
