HelloPharmacist Scorecard of Selenium 200 mcg by NutraBio
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: selenium at 200 micrograms per capsule. Selenium is an essential mineral your body needs for antioxidant protection and thyroid and immune function.
The capsule also contains inactive ingredients—rice flour, hypromellose (a plant-based capsule material), and water—that help deliver the selenium.
Does it work?
Strong evidence
Selenium has the strongest evidence for treating selenium deficiency itself. For Kashin-Beck disease (a joint disorder linked to low selenium), autoimmune thyroiditis (an autoimmune condition affecting the thyroid), and pre-eclampsia (high blood pressure in pregnancy), the evidence is considered possibly effective—meaning there's some promising research, but it's not definitive.
For dyslipidemia (abnormal blood fat levels), the available evidence suggests it's probably not effective.
How safe is it?
Well-documented data
Selenium at this dose—200 micrograms daily—is generally well tolerated and falls within the safe upper limit of 400 mcg per day for adults. The most common side effects from normal doses are mild gastric discomfort, headache, and rash.
At much higher doses, excess selenium can cause hair loss, nail changes, fatigue, nausea and vomiting, skin inflammation, and weight loss. The facts note that chronic exposure to very high levels of selenium may increase the risk of motor neuron problems and has been linked to increased skin cancer risk in some studies.
Pregnancy and lactation safety data on file shows pregnancy is listed as possibly safe and possibly unsafe (the data is conflicting), and lactation is possibly safe—talk with your doctor or pharmacist before taking this if you're pregnant or breastfeeding.
Meds to double-check
Moderate interaction found
Check your medications against this product before you start, especially if you take blood thinners or antiplatelet drugs (increased bleeding risk), warfarin, immunosuppressants, barbiturates, oral contraceptives, or niacin. Your doctor or pharmacist can tell you whether selenium is safe to combine with what you're on.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
If you're deficient in selenium or want to support thyroid and immune health, this supplement has solid evidence for deficiency and some promise for thyroid-related conditions. However, it does interact with blood thinners, immunosuppressants, barbiturates, and warfarin—so check with your doctor or pharmacist before starting if you take any of those.
Stay below 400 mcg daily to avoid toxicity, and remember that in pregnancy and breastfeeding, the safety data is mixed, so discuss it with your own healthcare provider first.

Selenium 200 mcg by NutraBio Drug Interactions
HelloPharmacist Interaction Report
NutraBio Selenium 200 mcg interacts with several medication types, with the most serious concern being blood thinners (anticoagulants) and antiplatelet drugs—selenium may increase bleeding risk by boosting a substance called prostacyclin that inhibits clot formation.
Read the full breakdown — every affected drug type, severity by severity
Moderate interactions also affect immunosuppressants (drugs that suppress your immune system may become less effective, since selenium can stimulate immunity), barbiturates (sedating drugs whose effects may be prolonged), and warfarin specifically (a blood thinner that selenium might interfere with by displacing it from protein binding or reducing liver metabolism). Altogether, these interactions span 321 individual medications.
There's also a minor interaction with contraceptive drugs—they may increase your selenium levels, though the real-world significance isn't clear—and niacin, where selenium might reduce its benefits for raising good cholesterol (HDL).

For each ingredient in Selenium 200 mcg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Selenium
Anticoagulant/Antiplatelet Drugs
Selenium may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Clinical research suggests that taking selenium 10 mcg/kg/day can increase bleeding times by increasing prostacyclin production, which inhibits platelet activity. Other clinical research suggests that taking selenium 75 mcg daily, in combination with ascorbic acid 600 mg, alpha-tocopherol 300 mg, and beta-carotene 27 mg, reduces platelet aggregation.
Barbiturates
Theoretically, selenium might prolong the sedating effects of barbiturates.
Laboratory research suggests that selenium can inhibit the hepatic metabolism of barbiturates. Selenium seems to prolong the sedative effect of pentobarbital in animal models.
Immunosuppressants
Theoretically, selenium supplementation may reduce the effectiveness of immunosuppressant therapy.
In vitro research and preliminary clinical evidence suggests that selenium may stimulate the immune system.
Warfarin (Coumadin)
Theoretically, selenium might interfere with warfarin activity.
Animal research suggests that selenium can increase warfarin activity. Selenium might interact with warfarin by displacing it from albumin binding sites, reducing its metabolism in the liver, or by decreasing production of vitamin K-dependent clotting factors. Selenium can also prolong bleeding times in humans by increasing prostacyclin production, which inhibits platelet activity.
Contraceptive Drugs
Contraceptive drugs might increase levels of selenium, although the clinical significance of this effect is unclear.
Some research suggests that oral contraceptives increase serum selenium levels in women taking oral contraceptives; however, other research shows no change in selenium levels. It is suggested that an increase could be due to increased carrier proteins, indicating a redistribution of selenium rather than a change in total body selenium.
Niacin
Selenium might reduce the beneficial effects of niacin on high-density lipoprotein (HDL) levels.
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease. It is not known whether this adverse effect is due to a single antioxidant such as selenium, or to the combination. It also is not known whether it will occur in other patient populations.
