Excellent!

Verified Purchase

I bought this because I wanted to take both zinc and selenium. I trust Dr. Mercola products because their ingredients are clean and reliable. The pills are comfortable to take and don't smell bad, so I'm happy with them. I also feel less tired and they seem to help with immune system management, so I'm satisfied.

Zinc and selenium

Verified Purchase

I really like this company Doctor Mikola, the quality is excellent, the composition of ingredients is excellent if you need zinc and selenium for the female body or to improve women's health, this is an excellent option, the size of the capsule is small, very convenient to use, I saw the result after the course, I closed my deficiencies, my hair began to fall out less, the packaging is convenient, I recommend it also strengthens the immune system

maybe the best there is

Verified Purchase

it has copper which is absolutely necessary for zinc to work as it should (Essential Synergy) , I hate the smell ,so it's better to take it with some food (don't take it with iron/calcium rich food like dairy)

I take it to support my immune system, thyroid gland, and skin. It is convenient that one capsule contains zinc and selenium in balanced doses - no need to buy two separate preparations. The capsules are medium-sized, easy to swallow, have no unpleasant smell or taste. I have not noticed any side effects, I take it in courses. The packaging is made of dark glass - it protects from light, and looks high-quality. Overall, I am happy, I feel more energy and my skin condition is better.

The Best Investment in Your Immunity — Why I Choose Dr. Mercola

Verified Purchase

I have been looking for the perfect complex to support the body for a long time, and this drug from Dr. Mercola has become a real find! I want to share my experience, because the quality of this brand is really felt from the first days. Why is this complex special? First of all, every ingredient is perfectly selected here. You get not just zinc, but a well-thought-out formula with selenium and copper, which is very important for the balance of trace elements. One serving contains the optimal amount of mg of the substance, which helps to quickly cover the deficiency in the body without overdose. The packaging is very reliable: dark glass protects the contents from sunlight, and 90 capsules are just enough for a full course. The capsule itself is of a convenient size, so there are no problems with swallowing. By the way, the taste is absolutely neutral, which is a big plus for me. Useful properties and my experience: Immunity: This is the main reason for my purchase. I noticed that during the cold season this complex works as a powerful antioxidant. It provides prevention of viral diseases, helping the body recover faster. Hair and skin: After a month of taking it, I noticed a real effect - my hair became stronger and had a healthy shine, and my skin became much cleaner. Overall energy: Zinc and selenium support the thyroid gland, so I feel much more cheerful. Conclusion: If you are looking for a working drug for health "from the inside", Dr. Mercola is the best for your money. I definitely recommend it! A review from me and a like from you - and let every ingredient in your body work like a Swiss watch! ⏳👍"
