excellent product Essentials product is a part of 1qt of veggies from juicer consumed each day. My recent lab profile from my annual checkup at my VA impressed my doctor. Also adds great flavor. I am 77yr mostly disabled (service connected) Nam vet .

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!!!!

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.

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!

Wonderful trustworthy products and customer service I have used the Silver Gel for many years now. I keep one in my purse and in car all times. Since the Sur2Fibr has come out, I've been very satisfied. If there are any issues or concerns, the customer service is friendly and very helpful. I've always been pleased with all contact.
