HelloPharmacist Scorecard of Seleno Met 200 mcg by Klaire Labs
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
Seleno Met 200 mcg is a single-ingredient supplement: selenium at 200 micrograms per capsule. Selenium is a mineral your body uses to make selenoproteins — compounds that act as antioxidants and support thyroid and immune function.
The capsule itself contains inactive ingredients (cellulose, a plant-based thickener, hydroxypropylmethylcellulose, water, and L-leucine) that help deliver the selenium.
Does it work?
Strong evidence
Selenium is likely effective for treating selenium deficiency, which can happen if you don't get enough from food. The evidence suggests it's possibly effective for Kashin-Beck disease (a joint condition linked to low selenium), pre-eclampsia (high blood pressure in pregnancy), and autoimmune thyroiditis (an immune attack on the thyroid).
However, research shows selenium is probably ineffective for improving cholesterol levels (dyslipidemia).
How safe is it?
Well-documented data
Selenium at 200 mcg per dose is generally well-tolerated when you stay within the safe upper limit of 400 mcg daily. The most common side effects are mild: gastric discomfort, headache, and rash.
At high doses, selenium can cause hair loss, skin inflammation, fatigue, nail problems, nausea, vomiting, and weight loss — and in rare cases, very high doses have caused organ failure. The data also shows that long-term high-dose selenium may increase skin cancer risk and has been linked to a rare nerve condition (amyotrophic lateral sclerosis, or ALS).
Pregnancy safety is unclear: some evidence suggests it's possibly safe, but other evidence suggests it may be possibly unsafe — talk with your doctor or pharmacist about whether to take it while pregnant. For breastfeeding, the limited data suggests it's possibly safe, but you'll want to confirm with your own healthcare provider.
Meds to double-check
Moderate interaction found
Blood thinners and antiplatelet drugs (like warfarin, aspirin, or clopidogrel) carry a Moderate risk — selenium may increase bleeding. Immunosuppressants, barbiturates, and warfarin specifically also have Moderate interactions documented.
If you take any of these, confirm with your doctor or pharmacist before adding this product.
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.
This supplement is for people who need to correct a selenium deficiency or who have specific conditions like Kashin-Beck disease where the evidence leans toward benefit. If you take any blood thinners, birth control, or barbiturates, or if you're on immunosuppressants or niacin, check with your doctor or pharmacist before starting.
Stick to the 200 mcg dose — don't add other selenium supplements on top of it, because too much can be toxic. Talk it over with your own healthcare provider to make sure it's right for you.

Seleno Met 200 mcg by Klaire Labs Drug Interactions
HelloPharmacist Interaction Report
Seleno Met 200 mcg by Klaire Labs contains selenium, which has documented interactions with several medication types.
The most serious concern is with blood thinners (anticoagulants) and antiplatelet drugs — selenium may increase bleeding risk by thinning your blood further, which is a Moderate severity interaction.
Read the full breakdown — every affected drug type, severity by severity
Selenium also interacts with immunosuppressants (drugs that calm your immune system), where it may reduce how well they work. It can prolong the sedating effects of barbiturates, a class of older sedative medications.
Additionally, it may interfere with warfarin (Coumadin), a common blood thinner, by changing how your body processes it.
There are also Minor interactions documented: birth control pills may raise your selenium levels (though doctors aren't sure if this matters clinically), and selenium might reduce the cholesterol-raising benefit of niacin.
Altogether, these interactions span 321 individual medications. Before you start this supplement, run your exact medications through the checker on this page to see if any of yours are affected.

For each ingredient in Seleno Met 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.
