Overview
We keep Dr. Mercola Zinc Plus Selenium Dietary Supplement, 30 Servings on our zinc shelf alongside 52 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: Dr Mercola Zinc Plus Selenium brings together two of the most valuable everyday minerals in a single, simple capsule. This is a genuine immune duo. Both zinc and selenium contribute to the normal function of the immune system. That is the maker talking, not us, so read it as a claim rather than a finding. On Amazon it sits at 4.5 out of 5 across 1,200 ratings. How that compares with the rest of the shelf is below.

Across the 53 rated zinc products we track, the middle of the pack sits at 4.6 out of 5. This one scores 4.5. Bottom quarter of the shelf. Not a red flag by itself, but similar money buys a better-rated option here, so the case for this one has to come from somewhere else.
1,200 people rated it, where the shelf median is 597. That's enough for the score to mean something without being the last word on it.
On money, this sits in the top third of a shelf running from £3.64 to £81.00, with the midpoint around £12.99. Paying above the middle of the shelf needs a reason the star rating does not supply, because on ratings alone the extra money is not buying an advantage here.
Worked out from the 53 zinc products we track, not from the brand's own claims.

Key features, as the manufacturer lists them
Taken from the product listing via Amazon's product API. These are the seller's claims, not our test results.
TWO ESSENTIAL MINERALS IN ONE: Dr Mercola Zinc Plus Selenium brings together two of the most valuable everyday minerals in a single, simple capsule. Zinc and selenium each play important roles in the body and work well as a pair, so one daily capsule covers both without the need for separate supplements. With 30 capsules per bottle, it is an easy one-a-day, 30-day supply that keeps two easily overlooked essentials topped up as part of your routine.
SUPPORTS YOUR IMMUNE SYSTEM: This is a genuine immune duo. Both zinc and selenium contribute to the normal function of the immune system, so they work together to help support your body's natural defences day to day. It makes this a sensible, simple choice for anyone who wants to look after their immune system through the busy, colder months, or simply keep a dependable daily foundation in place all year round – real, authorised support in every capsule.
ANTIOXIDANT PROTECTION FOR CELLS: Zinc and selenium are both valued antioxidants. Each contributes to the protection of cells from oxidative stress, helping defend your body against the everyday wear and tear of modern life. Having both in one formula gives you well-rounded antioxidant support from two complementary minerals at once, making Dr Mercola Zinc Plus Selenium a smart, considered addition to your daily wellbeing routine rather than a single-nutrient one-trick supplement.
GOOD FOR SKIN, HAIR AND MORE: Beyond immunity, these minerals are real multitaskers. Zinc helps maintain normal skin, hair and nails, supports normal cognitive function and has a role in cell division and DNA synthesis, while selenium supports normal thyroid function and the maintenance of normal hair and nails. Together they look after several aspects of your health at once, from your natural defences to the way you look and feel every day.
NON-GMO, SOY & GLUTEN FREE: We have kept the formula clean and considerate. Dr Mercola Zinc Plus Selenium is non-GMO, soy free and gluten free, so it suits a wide range of dietary preferences and sensitivities – a particularly handy top-up for those on plant-based diets, where zinc can be harder to absorb. The simple one-a-day capsule needs no measuring or fuss. Choose Dr Mercola and keep the essentials covered, one capsule a day.
