HelloPharmacist Scorecard of Super Natural Selenium by Vibrant Health
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
Super Natural Selenium contains two active ingredients. Broccoli powder is included for its nutrient profile, and Phytavail™ Selenium is a form of the mineral selenium.
The product has no other inactive ingredients listed. Both work together in the formula, though they have different roles: broccoli contributes various plant compounds, while selenium is a trace mineral your body needs for several functions.
Does it work?
Not established
Selenium in this product is likely effective for selenium deficiency and possibly effective for Kashin-Beck disease (a joint condition linked to low selenium), pre-eclampsia in pregnancy, and autoimmune thyroiditis (a type of thyroid disease). The evidence suggests it may not help with dyslipidemia (abnormal blood fat levels).
Broccoli powder is possibly effective for colorectal cancer prevention, but the evidence for bladder cancer, breast cancer, and fibromyalgia isn't established yet in the data we hold.
How safe is it?
Well-documented data
Selenium is generally well tolerated in the recommended amounts — the daily upper safe limit is 400 mcg. At normal doses, the most common side effects are gastric discomfort, headache, and rash.
However, excess selenium is toxic and can cause serious problems including hair loss, nail changes, fatigue, nausea, and in rare cases multi-organ failure. Broccoli as a food is safe, but concentrated supplements haven't been studied as thoroughly; the facts advise avoiding high-dose broccoli extracts unless your doctor approves.
Both ingredients are rated likely safe in pregnancy and lactation, though the concentrated forms are less studied than food sources. The facts note that long-term high selenium intake may increase the risk of certain skin cancers and possibly affect nerve health.
Meds to double-check
Moderate interaction found
Check with your pharmacist before using this product if you take blood thinners or antiplatelet drugs (like aspirin or warfarin), immunosuppressant medications, barbiturates (sedatives), birth control pills, or niacin supplements. Broccoli powder may also reduce the effectiveness of medications broken down by your liver's CYP1A2 or CYP2A6 enzymes — ask your pharmacist if any of your drugs use those pathways.
The bottom line
Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
This product may work for selenium deficiency and a few other specific conditions, but only if you take the right dose — too much selenium is harmful. If you take blood thinners, immunosuppressants, barbiturates, or warfarin, or if you're on birth control or niacin, check your exact medications with the tool on this page before starting.
Ask your pharmacist whether the dose in this product is right for you and whether it fits your current prescriptions.

HelloPharmacist Interaction Report
Super Natural Selenium by Vibrant Health contains two active ingredients, and one of them — selenium — has documented interactions with several medication types.
The most serious concerns involve blood thinners (anticoagulants/antiplatelet drugs). Selenium may increase bleeding risk by boosting a compound called prostacyclin, which reduces how your blood clots.
If you take warfarin (Coumadin) or similar medications, this needs attention: research suggests selenium can make warfarin work harder, possibly by freeing it from its carrier proteins or affecting how your liver processes it.
Read the full breakdown — every affected drug type, severity by severity
The broccoli powder in this product may reduce how your body breaks down certain medications. It contains compounds called glucosinolates that can speed up liver enzymes called CYP1A2 and CYP2A6, potentially making drugs metabolized by those pathways less effective.
Additionally, selenium may interfere with immunosuppressant medications (by stimulating your immune system), barbiturates (by prolonging their sedating effect), and niacin supplements (by reducing their benefits for cholesterol). Birth control pills might raise your selenium levels, though it's unclear if that matters clinically.
Additionally, minor interactions are documented with contraceptive drugs and niacin. Altogether, these interactions span 451 individual medications.

For each ingredient in Super Natural Selenium 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.
Phytavail(TM) 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.
Broccoli powder
Cytochrome P450 1A2 (Cyp1A2) Substrates
Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP1A2.
Pharmacokinetic research in humans shows that eating 500 grams of fresh broccoli daily for 6-12 days can increase CYP1A2 activity by 10% to 200%. Induction of CYP1A2 activity by broccoli is attributed to its glucosinolate constituents.
Cytochrome P450 2A6 (Cyp2A6) Substrates
Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP2A6.
Pharmacokinetic research in humans shows that eating 500 grams of broccoli daily for 6 days increases CYP2A6 activity by 135% to 550%. Induction of CYP2A6 activity is attributed to its glucosinolate constituents.
