The best! Im so glad I bought this Vitamin D. The main appeal was that it was mushroom derived and included other minerals as well as Magnesium which is required to be able to absorb the Vitamin D. It has worked wonders and I can definitely notice a difference if I forget to take it in the morning. I will be buying this product for life...im not even exagerating.

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.

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 took silver liquid faithfully every… I took silver liquid faithfully every day during the COVID-19 crisis thing and my daughter is a nurse and she told me that I’m going to get Covid for sure and I said not if I’m taking a silver and I never even had a cold I never had a flu symptoms or anything and I still don’t I love the stuff. Also, I cured thrush in my husband‘s mouth after he took antibiotics, they gave him some medication to heal it, but it didn’t work. I gave him silver he was healed in no time.

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!
