Tried my first bottle of Vitamin C Tried my first bottle of Vitamin C. You can not get this quality of Vitamin C in health food stores, or grocery stores. Thanks for another winter without a cold or flu.

Absolutely the best products ever!! Delivery is fast, never an issue. Love the silver, its very effective for humans and dogs, We take it twice a day to keep our immune system running smooth. Love the throat drops, The lotion and jell works really good too for any skin condition. The price is very good.We are in our 70's and we rarely get sick,

These are absolutely amazing products These are absolutely amazing products. All of them. I can’t say what I like the most, the gel is probably my top followed very closely by the throat lozenges. Super happy someone introduced me to these products!

Best Supplements EVER! For the record, I am not a review writer. That’s not my thing-but these products have changed my life! I have used them for years now. My immune system deficiency always caused me to have severe illness-a little cold or sniffle always led to secondary infection. I started out using SilverSol at the first sign of a cold and realized it helped with getting me over illness so much quicker. Once I added the Vitamin D-GAME CHANGER!!! No more secondary infections and I usually feel great within a day. ABSOLUTELY NOTHING compares to these products!! Believe me, I have tried many over the years that never worked. Optivida products are the real deal! Don’t forget to get some Silver Gel too! It helps healing cuts, scrapes and burns. LOVE LOVE LOVE the Optivida products!!!!

I use the Liquid and the gel for just… I use the Liquid and the gel for just about everything. I never buy other brands because I know and trust your brand. I have been using your brand even before the name change. Probably at least 10 plus years. I even use it on my dogs for any cuts or scrapes. Works Wonders!
