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
This product contains 2 active ingredients: broccoli powder and Phytavail™ Selenium. Broccoli powder is a concentrated form of the vegetable, supplying compounds called glucosinolates.
Selenium is a mineral your body needs for various functions, and this form is designed for better absorption. There are no other inactive ingredients in this product.
Does it work?
Not established
Broccoli powder shows possibly effective evidence for colorectal cancer prevention. For bladder cancer, breast cancer, fibromyalgia, and gastric cancer, the evidence isn't established enough to rate.
Selenium is likely effective for selenium deficiency and possibly effective for Kashin-Beck disease (a joint disorder), pre-eclampsia (high blood pressure in pregnancy), and autoimmune thyroiditis (an immune condition affecting the thyroid). For dyslipidemia (abnormal blood fat levels), selenium appears possibly ineffective.
How safe is it?
Well-documented data
Broccoli as a food is fine, but the safety of concentrated supplements is less studied — your doctor should approve before you use a concentrated extract. At normal dietary amounts, selenium is well tolerated, but high doses can be toxic.
Common side effects from selenium at recommended doses include stomach discomfort, headache, and rash. Excessive selenium can cause hair loss, skin problems, fatigue, nail changes, nausea, vomiting, and weight loss.
Rarely, very high amounts have caused serious organ damage. For pregnancy, selenium is possibly safe but also possibly unsafe — talk with your doctor or pharmacist about whether it's right for you.
During breastfeeding, it's rated possibly safe.
Meds to double-check
Moderate interaction found
Before taking this product, check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (the risk is moderate and involves bleeding). Also double-check if you're on immunosuppressants, barbiturate sedatives, warfarin, birth control pills, or niacin.
No interactions are documented for the broccoli powder with most drugs, but it may affect how your liver processes certain medications — your pharmacist can check your specific prescriptions.
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 help with selenium deficiency and possibly support thyroid health, but it's not right for everyone. If you take blood thinners, immunosuppressants, barbiturates, birth control, or niacin, you'll want to check with your doctor or pharmacist before starting.
Stick to the recommended dose — excess selenium can cause real harm. Talk it over with your own healthcare provider to see if it fits your situation.

HelloPharmacist Interaction Report
Super Natural Selenium by Vibrant Health interacts with medications through both its broccoli powder and selenium content.
The most serious interaction is with blood thinners (anticoagulants) and antiplatelet drugs like warfarin — selenium may increase bleeding risk by affecting how your blood clots.
Read the full breakdown — every affected drug type, severity by severity
Broccoli powder can speed up how your liver breaks down certain drugs metabolized by CYP1A2 and CYP2A6 enzymes, potentially making those medications less effective. This effect was seen in studies where people ate large amounts of fresh broccoli daily for up to two weeks.
Selenium also interacts with immunosuppressants (which suppress immune activity), barbiturate sedatives, warfarin specifically, birth control pills, and niacin. With immunosuppressants and barbiturates, the concern is reduced drug effectiveness or prolonged sedation.
Birth control and niacin interactions are minor but worth knowing about.
Altogether, these interactions span 455 individual medications. Use the medication checker on this page to look up your exact prescriptions before you start.

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.
