HelloPharmacist Scorecard of Selen 200 mcg by Amvilab
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
Selen 200 mcg is a straightforward single-ingredient supplement: it contains selenium, a mineral your body needs for thyroid function, immunity, and antioxidant protection. The 200 microgram dose is packaged in a capsule with inactive ingredients — rice flour, cellulose, magnesium stearate, and silicon dioxide — which are there to hold the capsule together and keep the powder from clumping.
Does it work?
Strong evidence
Selenium is likely effective for treating selenium deficiency, which can happen in people who eat very little seafood, meat, or nuts. The evidence is less clear for other uses: it's possibly effective for Kashin-Beck disease (a joint condition linked to low selenium), pre-eclampsia in pregnancy, and autoimmune thyroiditis (Hashimoto's disease).
For high cholesterol and triglycerides, the evidence suggests it's probably not effective.
How safe is it?
Well-documented data
Selenium at 200 mcg is generally well-tolerated — this dose is below the daily upper limit of 400 mcg that experts consider safe for regular use. The most common side effects are mild: stomach discomfort, headache, and rash.
However, avoid taking more than the recommended dose without your doctor's guidance. At high doses, selenium can cause hair loss, nail changes, fatigue, nausea, and in rare cases serious liver or organ damage.
Long-term exposure to very high selenium levels has also been linked to nerve damage and increased skin cancer risk, so this is a supplement you don't want to overdo.
Meds to double-check
Moderate interaction found
Check with your pharmacist before starting if you take blood thinners or antiplatelet drugs (Moderate risk of increased bleeding), warfarin (Coumadin) specifically (Moderate risk of interference), immune-suppressing medications (Moderate risk of reduced effectiveness), barbiturates (Moderate risk of prolonged sedation), birth control pills (Minor — may raise your selenium levels), or niacin for cholesterol (Minor — may reduce its HDL-raising effect).
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you've been told you have low selenium or you eat a very limited diet, this supplement makes sense — it's a modest, well-tolerated dose. If you take blood thinners, birth control, immunosuppressants, or niacin for cholesterol, or if you take older sedating medications, check with your pharmacist first.
Don't take more than directed, and talk to your doctor if you have any concerns about long-term use.

Selen 200 mcg by Amvilab Drug Interactions
HelloPharmacist Interaction Report
Selen 200 mcg by Amvilab contains one active ingredient — selenium — which does interact with a number of medications.
The most serious concern is with blood thinners (anticoagulants) and antiplatelet drugs: selenium may increase bleeding risk by affecting how platelets work, and it may also interfere with warfarin (Coumadin) specifically by changing how your body processes it.
Read the full breakdown — every affected drug type, severity by severity
Selenium may also reduce how well immune-suppressing drugs work if you're taking them after an organ transplant or for an autoimmune condition. It could theoretically prolong the sedating effects of barbiturates, an older class of sleep or seizure medication.
There's also a minor interaction with birth control pills — they may raise your selenium levels, though we're not sure how much that matters in practice — and selenium might reduce niacin's beneficial effects on HDL cholesterol if you're taking both.
Altogether, these interactions span 317 individual medications. Before you start this supplement, use the medication checker below to see if any of your prescriptions are on the list.

For each ingredient in Selen 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.
