- Brain Basics Opti Zinc Plus - Zinc Supplement with Quercetin, EGCG, and Copper. Immune Support Formula - 60 Capsules

Works great for colds

This pill is great in that it has everything you need in one pill. However, I have a hard time swallowing them. They do not have a coating, so one got stuck in my esophagus. My husband has no problem swallowing them, so he is taking them. He likes that it has zinc and quercetin in one tablet. I went back to taking two capsules instead.

I searched high & low, however Brain Basics brand Opti Zinc Plus was the only formula on Amazon I could find that combined exactly the ingredients I heard works best for Zinc absorption. Containing Zinc in the form of Zinc biglycinate, as well as the Ionophores Quercetin & EGCG as well as to aid in absorption on a cellular level. Plus as an added bonus it has Copper in the correct ratio to the Zinc in the product, this will help keep you safe from the Zinc depleting your copper. All this and all the ingredients not in a crazy low or excessively high level. This is what made Opti Zinc Plus by Brain Basics my choice for my daily Zinc Supplement. I think you’ll love it too!

I'm sure it would've been a good product for immune defense, but unfortunately quercetin makes me nauseous. Keep in mind of this ingredient when ordering.

I bought this zinc to prepare my body should I come in contact with Covid 19. I believe studies are showing if you have zinc already at a good level in your blood you will have milder symptoms. Green basics also has the added benefit of quercetin, also known good for supporting the body against Covid. The green tea and copper are added bonuses!

I have taken these for about two weeks and honestly, I expect to have some improved mental clarity or even better resistance to the common cold, etc. Nothing, no effect at all. I am not sure what to say, but I would have a hard time recommending these.

We’re using this because Zinc with Querticin is a good immunity booster. We’re still waiting for our State to implement a Covid vaccination program. Until then, we’re using every tool we have to stay virus free. This item arrived very quickly and well packaged. We find the tablets easy to swallow and haven’t experienced any stomach irritation.

Purchased because of the combination of vitamins— zinc & quercetin, which need each other to “work.” Tiny flat vitamin is easy to swallow. Can’t say I notice or feel a difference, but will keep taking since it contains essentials important to fighting viruses!
