HelloPharmacist Scorecard of Selenium-Chelate by Nutri-West
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
Selenium-Chelate contains 12 ingredients. The active ones include liver extract (derived from animal liver) and selenium, a mineral your body needs in small amounts for thyroid function and immune health.
The other 10 ingredients are animal tissue concentrates — adrenal, parotid, pituitary, duodenum, kidney, thymus, spleen, pancreas, heart, and stomach — which are included as part of a glandular or organ-support formula. There are no inactive filler ingredients listed.
Does it work?
Strong evidence
Selenium itself is likely effective for selenium deficiency and possibly effective for Kashin-Beck disease (a joint disease linked to low selenium), pre-eclampsia (pregnancy-related high blood pressure), and autoimmune thyroiditis (an autoimmune thyroid condition). It's rated possibly ineffective for dyslipidemia (abnormal blood fat levels).
Liver extract, on the other hand, is rated possibly ineffective for chronic fatigue syndrome and has insufficient evidence for hepatitis C. The effectiveness of the other tissue concentrates in this formula isn't established in our data.
How safe is it?
Well-documented data
Selenium is generally well-tolerated in the recommended dietary amounts — up to 400 mcg daily — but excess selenium can be toxic. The most common side effects at normal doses are stomach discomfort, headache, and rash; at high doses, excessive selenium can cause hair loss, skin inflammation, fatigue, nail changes, nausea, vomiting, and weight loss.
Liver extract carries caution flags: it can deliver very high levels of vitamin A (which may harm a developing baby) and heme iron, and there's concern about source quality and possible contamination from sick animals or BSE-infected tissue, though no human cases of BSE transmission from liver extract have been reported. The safety of the tissue concentrates hasn't been well studied.
During pregnancy, selenium is rated possibly safe, though high doses may be unsafe; during breastfeeding, it's rated possibly safe. Talk with your doctor or pharmacist before using this product if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before you take Selenium-Chelate, double-check with your doctor or pharmacist if you're on blood thinners (anticoagulants) or antiplatelet drugs — selenium may increase bleeding risk and may interfere with warfarin. Also flag any immune-suppressants, barbiturates or sedatives, birth control pills, niacin supplements, or iron supplements or medications.
The liver extract in this product adds concerns for anyone on warfarin or taking iron.
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.
Selenium-Chelate is aimed at people looking to support their immune and thyroid function with glandular tissue, and selenium alone has good evidence for selenium deficiency and some evidence for certain thyroid and pregnancy-related conditions. However, if you take blood thinners, immune-suppressants, barbiturates, or birth control pills, you'll need to check with your doctor or pharmacist first — the interactions are real and may affect how your medications work.
The liver extract component also raises concerns about vitamin A levels and source quality, especially in pregnancy. Have your doctor or pharmacist review your full medication list and health history before starting.

Selenium-Chelate by Nutri-West Drug Interactions
HelloPharmacist Interaction Report
Selenium-Chelate by Nutri-West contains two ingredients with documented interactions: liver extract and selenium.
The most serious concern is selenium's Moderate interaction with blood thinners (anticoagulants) and antiplatelet drugs — selenium may increase bleeding risk by thinning your blood further, and it may also interfere directly with warfarin (Coumadin) activity.
Read the full breakdown — every affected drug type, severity by severity
Selenium also has Moderate interactions with immune-suppressant medications (it may reduce their effectiveness), barbiturates or sedatives (it may prolong their sedating effects), and a Minor interaction with birth control pills (which may raise your selenium levels, though the clinical significance isn't clear). It also has a Minor interaction with niacin, potentially reducing its beneficial effects on HDL cholesterol.
Liver extract carries Minor interactions with warfarin through its vitamin K content — theoretically, changing how much you take could affect warfarin's blood-thinning power — and with iron supplements or medications (extra iron intake could raise the risk of stomach upset or iron overload, especially at high doses or with prolonged use).
We could not check several other ingredients — adrenal, parotid, pituitary, duodenum, kidney, thymus, spleen, pancreas, and heart tissue concentrates — because we hold no interaction data for them. Run your exact medications through the search tool on this page before you start.

For each ingredient in Selenium-Chelate with known interactions, here are the types of medications they 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.
Liver
Iron
Liver extract can contain heme iron. Taking liver extract with iron-containing medications or supplements may increase total iron intake and could increase the risk of gastrointestinal adverse effects or excessive iron accumulation. The risk is greater with high doses, prolonged use, or in individuals with hemochromatosis or another iron-overload disorder. Review the iron content of the liver extract and the total elemental iron dose. Avoid unnecessary duplicate iron supplementation and consider monitoring ferritin and transferrin saturation when clinically appropriate.
Warfarin (Coumadin)
Liver extract products may contain small and variable amounts of vitamin K. Theoretically, starting, stopping, or substantially changing the amount of liver extract used could reduce the anticoagulant effect of warfarin and lower the INR. However, this interaction has not been directly studied or reported in humans, and the vitamin K content of liver extract products is generally not standardized. Consider monitoring the INR after a meaningful change in liver extract use.
