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 love the silver lozenges. I love the lozenges mostly because they have the silver in them. I would like to see aloe added to them and less mint. I don't care much about the mint and would like to see less of it in them. It's hard to find lozenges when you're a singer that are healthy.

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 .
