Can selenium cause weight gain?

There's no definitive answer to this question since everyone's body reacts differently to selenium. Some people may experience weight gain as a side effect of taking selenium supplements, while others may not notice any change in their weight. If you're concerned about gaining weight while taking selenium, speak to your doctor or a registered dietitian to get their professional opinion.

Do I need a selenium supplement?

Selenium is a mineral found in the soil. It is taken up by plants, which are then eaten by animals. Selenium is found in meat, fish, poultry, and grains. It is also found in some nuts and in certain fruits and vegetables. The body needs selenium to work properly. Selenium supplements are sometimes needed if the body does not get enough selenium from the diet. Selenium supplements are also used to treat some medical conditions.

Does selenium cause hair loss?

Does selenium give you energy?

Selenium is an important mineral that is found in small amounts in the body. It is important for many functions, including metabolism and thyroid function.

Selenium 200 Mcg for Thyroid, Prostate and Heart Health - Selenium Amino Acid Complex - Essential Trace Mineral with Superior Absorption, Non GMO, Gluten Free, Soy Free, 250 Capsules Review:


Other brands of selenium that I've taken as tablets have been really challenging for me to swallow. These capsules are significantly more effective and convenient to ingest. Exactly what I had hoped for. Order arrived really quickly. Definitely will purchase this brand again. Additionally, it is devoid of dairy, gluten, and soy, which is crucial to me when choosing a supplement.



Life Extension Super Selenium Complex Capsules, 200 mcg, 100 Count Review:


The human body needs selenium for good health. Problems arise from a lack, but an excess is also problematic. To put this assessment into perspective, a quick summary of data from the National Institutes of Health (NIH) is provided at the outset.1) Dietary selenium is usually sufficient for most people. Studies of blood levels as well as intake from food and supplements (2009–2010 National Health and Nutrition Examination Survey (NHANES)) have verified this (NHANES data from 2003–2004).a. Organ meats, seafood, and brazil nuts are the foods that have the greatest selenium. Muscle meats, cereals, breads, and other grains, dairy products, poultry, and eggs are other sources.b. Regional and soil factors will affect the amount of selenium in food.b. It is well known that some regions of China, some European nations, and New Zealand have extremely low amounts of selenium.c. People who eat mostly vegetarianism or veganism or avoid grains like wheat may need to take supplements.2) It is believed that the RDA for selenium is sufficient to cover the needs of 97-98% of healthy individuals. It ranges from 20 mcg for infants to 55 mcg for people 14 years of age and beyond. For people who are breastfeeding (60 mcg) or pregnant, it is higher (70 mcg).Re: Cancer risk The NIH states that selenium "may play a role in the prevention of cancer due to its effects on DNA repair, apoptosis, and the endocrine and immunological systems as well as other pathways, including its antioxidant characteristics." Selenium may be part of your prescribed treatment for cancer, but it should not be viewed as a substitute for it. Please keep in mind that having a potential role in prevention is not the same as treatment. Low selenium levels appear to increase the chance of developing certain cancers, including colorectal, prostate, lung, bladder, skin, esophageal, and stomach cancers. Please note that there are studies that support this position as well as studies that do not find that support due to the amount and kinds of selenium that people consume in their diets, as well as other factors including interactions between selenium and other minerals. Selenium is important, but it is not the only factor.4) With regard to cancer treatment, "Ovarian, bladder, lung, and other cancers are treated with cisplatin, an inorganic platinum chemotherapeutic drug. Cisplatin can lower serum and hair selenium levels, however it is unknown if these lower levels have any clinically meaningful effects. A few small studies have suggested that selenium supplementation can lessen the toxicity of cisplatin, however the authors of a Cochrane review found that there is insufficient data to support this claim (NIH). Tell your doctor and/or pharmacist about the selenium supplements you personally recommend, and ask them to stay informed.5) Concerning cardiovascular disease. "Selenoproteins assist in decreasing inflammation and avoiding platelet aggregation by preventing the oxidative alteration of lipids. Due to these factors, researchers have proposed that selenium supplementation may lower the chance of developing cardiovascular disease or dying from a cardiovascular disease-related cause (NIH). If you have major health concerns, ask your doctor to evaluate your selenium levels and proceed from there. Too much selenium is likewise undesirable.6) With regards to aging-related cognitive loss, serum selenium concentrations decrease. Selenium levels that are marginal or inadequate may be linked to age-related losses in brain function, presumably as a result of a decline in selenium's antioxidant action (NIH). Rather than selenium levels alone, it appears that overall nutritional health, which includes selenium, is related to mental capacities throughout time.Re: Thyroid Like iodine, selenium plays a crucial role in the manufacture and metabolism of thyroid hormones, and the thyroid gland has the highest concentration of selenium of any organ in the body (NIH). Selenium and iodine levels appear to interact to affect thyroid volume, goiter risk, and thyroid tissue injury risk. Women, people with thyroid conditions, and expectant mothers seem to need to be especially aware of this.Regarding dialysis. Some selenium from the blood is removed during hemodialysis. Along with dietary restrictions and anorexia, patients may have reduced uremia intake.9) Re: HIV. "Selenium levels are frequently low in HIV-positive individuals, presumably as a result of insufficient intakes (particularly in impoverished nations), high diarrheal losses, and malabsorption. Low levels of selenium have been linked to an increased risk of cardiomyopathy, death, and, in pregnant women, HIV transfer to unborn children and an early death of unborn children, according to observational studies (NIH).Re: Absorption problems. As always, you may need to take supplements if you have a health issue that interferes with your ability to absorb selenium.11) There is such a thing as TOO MUCH selenium. For people 14 years of age and older, 400 mcg is the maximum dose that is deemed reasonable. Beyond that point, signs of overdosing include a garlicky breath odor, a metallic taste in the mouth, brittleness and loss of the hair and nails, lesions on the skin and nervous system, nausea, diarrhea, skin rashes, discolored teeth, weariness, and irritability.12) Whether you have enough selenium or not does not depend on a guess. Your physician may prescribe tests. Your doctor can do a recent consumption test using blood or urine concentrations, or a long-term intake test using hair or nail analyses (that means over months or years). Your doctor may order tests for selenoprotein P and/or glutathione peroxidase as examples of how to determine your condition.13) The selenium form is significant when comparing supplements. Selenium-enriched yeast (produced in a high-selenium medium), sodium selenite, and sodium selenate are frequent forms found in supplements. More than 90% of selenomethionine is absorbed by humans, but only about 50% of selenium from selenite. This explains why a person could get varying outcomes when taking several supplements.14). Due to the fact that this product contains a variety of selenium forms, it can have a different impact on you than other selenium supplements. It is unlikely that taking more than one capsule daily would be beneficial at a combined level of 200 mcg, and even if you were told to take a supplement, it is possible that taking more than one may surpass suggested amounts. Clarify with your doctor what they want you to do. Keep in mind that selenium and other supplements can modify the effects of prescription drugs in one way or another. Bring your entire list of supplements to the pharmacist so they may compare it to your prescriptions. Additionally, there are online tools that check supplements for drug interactions. These might assist you in focusing your queries for your pharmacist and ensuring that no details are missed. This business does use independent third-party testing for content and purity, and it identifies each product with its lot number and expiration date. That's significant. Expect an inner seal inside the cap and a clear seal on the exterior. That one is actually for sale in my doctor's office. It may be simpler to compare a single form to any medicines you may be taking. Thanks!



Thorne Research - Selenomethionine - 200 mcg Selenium Supplement for Antioxidant Support - 60 Capsules Review:


This item is outstanding. I have noticedably more energy, reduced mental fog, and even unintentional weight loss. When I needed this supplement, I went with Thorne since I trust them from using some of their other products. Due to my Mthfr, I need to be closely watched during every pregnancy to help prevent miscarriage, which I had three of before they started giving me methylated folate and b vitamins. But every time they use the conventional test to check my thyroid—because a low thyroid can potentially lead to a miscarriage—it is always just barely inside the acceptable range. So, if they perform the t3 test and the other suggested tests that a functional medicine doctor would request, I assumed I would have a low thyroid. After my most recent pregnancy, I started seeing hair loss and a serious brain fog, so I got this product.I was genuinely shocked by how wonderful this made me feel. I wasn't aware that I had aches, but now that they're going away, I can tell how much better I feel.



Global Healing Center Selenium, 60 Capsules Review:


Hey there, Amazon users! I know that there are intelligent individuals like myself who can distinguish between genuine and fraudulent evaluations. I just want to remark that this is absolutely true and that it's funny. Many consumers grumble about the detox items they purchase because they expect them to function without making dietary changes. Yes, people, going fully vegan is the only way to see results. Whatever you're fighting, however difficult it may be, cannot stand a chance against green. I've had a throat infection for around eight months now. It has been seriously interfering with my mental health; I've seen multiple therapists, but they simply treat me like a lunatic and don't even try to assist. They essentially just push me to the side and earn their money off of my consultation. Nobody even paid attention to what I had to say or paused to consider that I might have acquired an uncommon infection. That was never ever thought of. The medical industry is truly sad, but it is a separate subject for another day. Returning to my throat, I've had two throat cultures that came back negative and a ton of blood work to support it. It resembles a bug or worm in every way. It consumes all of my food and all of my energy, but today I did notice something. It barely affects the energy I get from my greens in the slightest. Although my diet is quite strict and not everyone will follow it, I am doing it because I truly don't care how long it takes to get my life back. Stop doing everything if you want to quickly see actual results. Everything about it is poison. Green organic vegetables are necessary. And a wide range of them. Blend them in a blender to create juice. I've been following this diet for the past two weeks, and with the help of this product and all the other herbs I'm taking, I've come to realize just how weak my throat infection really was. It cannot compete with my diet of fasting and prayers to God. Therefore, before you give this product or any other product that you use to detox yourself a nasty review, keep in mind that detoxing also entails changing your entire diet and quitting eating the poison that these fast food restaurants and grocery shops refer to as meals. Because right now, as I type this, I can actually feel my immune system fighting this problem I've been having MUCH better. You guys are going to get harmed, but that is how you will know it is working. Push through the cravings, and anyone who objects to your diet (and believe me, they will, especially if you work in a workplace that enjoys potlucks like I do) needs to be avoided as much as possible because it's possible that they, too, are suffering from an infection that is causing terrible symptoms, and they are simply unwilling to put in the necessary effort to feel better. bringing you down once more with them. Whatever it is you're facing, you can overcome it! Good luck!



Solgar – Yeast-Free Selenium 200 mcg, 250 Tablets Review:


I often take a variety of vitamins and supplements. I've chosen to include them in my daily routine and have made the decision that this dosage of selenium is crucial to add in order to ascertain as best as I can what the right supplements and quantities are that I should take. I should include selenium, one of the trace elements our bodies employ in conjunction with vitamin e to give our antioxidant defenses, according to the advice I'm relying on, among other sources, including Eating Well for Optimum Health: The Essential Guide to Food, Diet, and Nutrition.According to the research I've done, selenium should be taken in an organic form in doses of 200 mcg, either bound to yeast or as selenomethionine. The dose of 200 mcg is over the adult recommended daily intake (usually found as 80-200 mcgs). These pills don't include any yeast, and the only active component is L-selenomethionine, which provides selenium. The tablets don't include any sodium, sugar, dairy, soy, gluten, wheat, yeast, artificial sweeteners, colors, or preservatives.Given that the two nutrients are more efficiently absorbed into the body when taken together, selenium and vitamin E are advised to be taken together. My personal preference for vitamin E is another one from Solgar: D-Alpha Tocopherol and Mixed Tocopherols 400 IU Mixed Softgels by Solgar.Since I've been using this Solgar product for a while, I'm happy with the quality. I recently started buying this larger 250 tablet quantity instead of the 100 tablet version of Solgar - Yeast-Free Selenium 200 mcg, 100 Tablets because it is marginally more affordable.The selenium is not available as a gel tablet, at least not from Solar and not in the form that is offered with these tablets, for some reason. The tablets are slightly more difficult to swallow than softgels.In my opinion, this is one of the best Selenium tablet options on Amazon. If I discover later that a comparable or superior option is available, I'll edit my review to reflect that discovery.



NOW Foods Selenium 200 mcg VCaps, 180 ct Review:


Since selenium is essential for producing thyroid hormones and converting T4 to active T3, which always helps when my thyroid slows, I have been taking it for years. Additionally, according to research, it reduces the harmful consequences of too much iodine on the thyroid, which are more common than most people know because it is added to table salt, which raises urinary iodine excretion. It defends against damage caused by free radicals as an antioxidant. You can increase your glutathione levels with selenium, and I've found that this helps with heavy metal and toxin detox. Since mercury attaches to selenium, I had discovered that supplementing with more of it was crucial when I was dealing with excess mercury. I used to use some blackstrap molasses or a few Brazil nuts as natural sources of selenium, but I think that this selenium is so much better and simpler to take. Most selenium supplements have a faint smell. The only reason for the 4 and not 5 stars is because, if I were wealthy, I would buy everything without fillers, such as the 3x more expensive Pure Encapsulations selenium. I wonder if I entirely stopped using fillers whether my natural pheromones would rise and if millions of women would start chasing me like an axe commercial. Maybe I should give that a shot and see what happens. Since our bodies are a balance beam, both a deficit and a significant excess can lead to issues. In the interim, I've had good luck with this product, and I obtain a hair tissue mineral study to check the levels.



Selenium 200mcg for Thyroid, Prostate and Heart Health - Essential Trace Mineral with Superior Absorption - Yeast Free - 100 Once Daily Vegetable Capsules - Manufactured in The USA Review:


Due to my hypothyroidism, my thyroids are unable to convert T4 into T3. Selenium is likely the second most significant mineral affecting thyroid function after iodine. The thyroid is the organ with the highest weight concentration of selenium. Without selenium, thyroid hormone would not be activated by the enzymes that transform T4 into T3 by removing the iodine molecules from it. Selenium levels in patients with various thyroid conditions were all found to be lower than those of healthy individuals. According to several researchers, selenium administration will enhance T4 to T3 conversion. The thyroid gland itself is protected in part by selenium. Hydrogen peroxide is produced by thyroid cells, which are then used to produce thyroid hormone. The thyroid gland is shielded by selenium from the oxidative harm brought on by these processes. High iodine levels cause the thyroid gland's cells to be destroyed in the absence of sufficient selenium.



Go Nutrients Selenium 200mcg Supplement - Yeast Free Liquid Drops - Helps Support Thyroid Health, Fight Free Radicals & Boost Immune System - 1 oz Bottle Review:


This selenium is great. I used to have a little hypothyroid condition, but I was able to overcome it by adopting a paleo diet. I wanted to be sure I was getting all the appropriate nutrients now that I've switched to veganism. I switched to individual vitamins since I didn't think my multivitamin was working. To aid my thyroid, I combine selenium with nascent iodine. I had no idea that the two would immediately improve my mood so significantly! It was like day and night the change. I'm very happy I came across this selenium. It's a relief to know this exists! And minutes after taking it, I feel better in real life!



Nature's Way Selenium 200 mcg, L-Selenomethionine, Antioxidant, 100 Capsules (Packaging May Vary) Review:


I've now had four or five bottles of Natures Way Selenium 200mcg. When I first started using this product, I felt relief nearly right away. Believe it or not, my desires for alcohol, especially beer, have fully stopped as my age and liver spots fade. I had everyday beer cravings, especially in the late afternoon after a long day. Water simply couldn't do the task. My weight is currently reducing as a result. The fact that I converted to a micro-lingual selenium is what I find to be the most fantastic aspect of this product. I believed that it would improve the absorption. So, after a short while, all of my problems reappeared. In order to get back on track, I have started using the Nature's Way brand again.



Pure Encapsulations - Selenium (Selenomethionine) - Hypoallergenic Antioxidant Supplement for Immune System Support* - 60 Capsules Review:


After reading the Hashimoto Protocol book, I was really optimistic that this product would work, however I haven't noticed any changes in my hair loss. Consider this: studies from the National Institutes of Health (NIH) suggest that long-term selenium use may raise the risk of acquiring Type-II Diabetes.**Update: Since I was able to manage my anemia, my hair loss has significantly decreased. I discovered I was SEVERELY anemic after having extensive blood testing done. My feritin levels are good since I started taking PE's Opti-Ferin C, which has been nearly a year now. My labs have been fantastic since I added back the selenium, PE's 15 mg zinc, and the o.n.e (for Hashimotos). Additionally, EVERYONE with a thyroid disorder MUST take PE's B-Complex! I only regret not starting to take it years ago. If you start taking their B-Complex, Hashimoto's patients report feeling like their "old" selves before the diagnosis. Lots of energy, a sharp mind, serenity, joy, and most importantly, the anxiety will vanish entirely. It really is a miracle. Returning to selenium, I felt that it had also alleviated some of my symptoms and was an essential component of the regimen required to treat the wide range of thyroid problem symptoms.
