Best Selenium Supplement FAQs

Selenium is an important mineral for human health, but many people are not sure how to get enough of it in their diets.

Not only is selenium essential for human health, but it's also hard to come by. The best way to make sure you're getting enough selenium is to take a supplement, but with so many options on the market, it can be hard to know which one is right for you.

We did the research so that you don't have to. Based on our findings, we've compiled a list of the most frequently asked questions about selenium supplements and found the best answers for each one.

What Is the Best Form of Selenium to Take?

The best form of selenium to take is in the form of a supplement. Selenium supplements come in many different forms, including capsules, tablets, and liquid forms. Capsules and tablets are the most common forms of selenium supplements.

The recommended dose of selenium is 200 micrograms (mcg) per day for adults. however, some people may need to take more or less depending on their specific health needs.

Liquid forms of selenium are also available, but they are not as commonly used. Selenium can also be found in food sources, such as Brazil nuts, seafood, meats, and poultry.

However, it is important to note that the amount of selenium in food sources can vary widely. So, if you're looking to increase your selenium intake, a supplement is the best way to do it.

Life Extension Super Selenium Complex is another example of a comprehensive selenium supplement that provides the body with everything it needs to function at its best.

Is 200 Mcg of Selenium Too Much?

There is no RDA (Recommended Dietary Allowance) for selenium, and the upper limit is 350 micrograms per day for adults. Some people may need more selenium than others depending on factors like age, gender, health status, and diet. For example, pregnant or lactating women need more selenium than other adults.

Excessive intake of selenium can cause a number of health problems including gastrointestinal upset, hair loss, white spots on the nails, garlic breath odor, and mild nerve damage. Selenium toxicity is rare but can occur at very high doses (15-20 milligrams per day). If you are taking a supplement that contains 200 micrograms of selenium, you are not at risk of selenium toxicity.

Nutricost Selenium Capsules are a good example of a selenium supplement that provides the recommended daily dose of selenium.

Is It Worth Taking Selenium Supplements?

There is no one-size-fits-all answer to this question as the amount of selenium that a person needs depends on their age, sex, and other factors. However, most people can get the recommended amount of selenium by eating a healthy diet that includes plenty of selenium-rich foods such as seafood, meat, eggs, Brazil nuts, and mushrooms.

That said, some people may still benefit from taking a selenium supplement if they are not getting enough from their diet. Selenium supplements can be especially helpful for people who eat a lot of processed foods or who live in areas where the soil is low in selenium.

A healthy immune system is important for everyone, but it's especially critical during cold and flu season. If you're looking for a way to give your immune system a boost, selenium supplements are a great option.

Who Should Not Take Selenium?

While selenium is generally safe, there are a few people who should not take it. These include pregnant women, children, and people with certain medical conditions.

Pregnant women should not take selenium because it can increase the risk of miscarrying. Children should not take selenium because it can interfere with their development. People with certain medical conditions, such as diabetes or heart disease, should not take selenium because it can make these conditions worse.

Negative health outcomes are more likely to occur at high doses of selenium. Therefore, it is important to talk to your doctor before taking any selenium supplement, especially if you are pregnant, breastfeeding, or have a medical condition.

What Are the Signs of Selenium Deficiency?

Selenium deficiency can cause hair loss, brittle nails, white patches on the skin, impaired thyroid function, and a weakened immune system.

Selenium is a trace mineral that's important for overall health. It's involved in many biochemical processes in the body, including reproduction, thyroid function, and immunity. A selenium deficiency can cause a variety of health problems.

Signs of selenium deficiency include hair loss, brittle nails, white patches on the skin (especially around the eyes and nose), an enlarged liver or spleen, impaired thyroid function (including an underactive thyroid or Graves' disease), and a weakened immune system. Some people with selenium deficiency also experience problems with balance and muscle control.

Can I Take Selenium and Zinc Together?

There is no research to support taking selenium and zinc together as a single supplement, though they are often found in multivitamin supplements. Some people believe that the two minerals have complementary actions, with selenium providing antioxidant protection and zinc playing a role in immune function.

It's generally recommended that you take no more than 100 mg of zinc per day (or 50 mg if you're over the age of 50), and 400 mcg of selenium per day. Excess levels of either mineral can be toxic, so it's important to speak with a healthcare professional before starting any supplementation regimen.

Selenium supplementation is generally considered safe, but there are a few potential side effects to be aware of. These include gastrointestinal upset, hair loss, and nervous system problems such as weakness and muscle pain. Selenium can also interact with certain medications, so it's important to speak with a healthcare professional before taking any supplement.

Can I Take Selenium and Magnesium Together?

Yes, you can take magnesium and selenium together. However, it's important to note that too much selenium can be harmful, so it's best to consult with a healthcare professional before taking any supplements. Magnesium is a safe mineral to take in high doses, but it's always best to speak with a doctor if you're unsure about whether or not a supplement is right for you.

Should I Take Selenium in the Morning or at Night?

There is no right or wrong time of day to take selenium supplements, as each person’s body will metabolize the selenium differently. However, it is generally recommended that you take selenium supplements in the morning, as this will give your body enough time to absorb the nutrient before you go to bed. Additionally, taking selenium in the morning may help improve your energy levels throughout the day.

Is 400 Mg of Selenium Too Much?

It is not possible to overdose on selenium from food or supplements because the body has a tightly regulated system for excreting any excess. The tolerable upper intake level (UL) for selenium, set by the US Food and Nutrition Board, is 400 micrograms (mcg) per day.

The recommended dietary allowance (RDA) for selenium is 55 mcg/day for adults, so 400 mcg/day is more than seven times the RDA. While it's technically safe to consume this much selenium, it's not necessary and could be harmful. Selenium toxicity can cause hair loss, brittle nails, garlic breath odor, nausea, vomiting, diarrhea, abdominal pain, and nerve damage. If you're concerned that you're getting too much selenium, speak with a healthcare professional.

What Foods Are Highest in Selenium?

When in doubt, always err on the side of caution and take the lower dose. After all, it's better to be safe than sorry!
