Let customers speak for us
from 13 reviewsI couldn’t be more thankful for these vitamins! I was experiencing knee pain that would have me in tears, and it would happen so often that it getting concerning to me. I thankfully had noticeable relief pretty quickly after starting to take these daily! It was so easy to get in the routine of taking them. Over the months, I have almost forgotten what it was like to be in constant pain! Love love love

I personally started taking this for anti-inflammatory help, and really couldn’t be happier that I did! I’m specifically most excited about how it has helped my skin look more even and calm. I believe these are very good quality, as I’ve tried taking turmeric supplements in the past and have never experienced results like this!

I take these daily and have felt great since, especially in the months when I’m cooped up inside more often!

I cannot express how grateful I am for these vitamins! I saw a noticeable difference in my life overall after adding these to my dailies. I feel that I experience less frequent anxiety and lows, and with less intensity. It’s a huge relief to be able to take something natural with my other vitamins and experience such a difference. Routine is very important, and I believe that is the case with these! I make sure to take them daily.

I take emdefense all year round! It seems to help me from getting sick as I very rarely do now. I really like taking these for the respiratory benefits.

I’ve tried so many different vitamins over the years, giving them time to see how they work, and I can honestly say that these are the only ones that have ever really worked for me! I have been taking them consistently for over a year and definitely will never stop! I really just thought I had bad hair genetics, but it has been growing like a weed and is so much thicker since it breaks less now, which is huge for me. My nails are also super hard and grow long easily, so I no longer have to get my nails done!

These are amazing!! I caught a virus from family during the holiday, and I was the only one who didn’t get a respiratory infection or bronchitis. I never even developed cough! I began taking these before the visit (when I knew I would be exposed), throughout having symptoms, and afterward to make sure I stayed in the clear. I’m definitely keeping these up during the rest of cold/flu season, and having them on hand in general. I recently referred my coworker to EmDefense because she’s been struggling with a respiratory infection. My order arrived super fast too, thank you so much Wivi!!

High quality chelated mag at a great price! The addition of malic acid is a nice benefit.

Love these, my nails are noticeably stronger and stopped peeling after a week. I really like how dosage is 2 capsules rather than 3+ large chalky tablets like other brands. More holistic and specialized ingredients also, A+

I was having the hardest time kicking a respiratory virus. I started incorporating these supplements and my symptoms started dissipating! Would definitely recommend them to anyone who wants that extra immune support!

Started using this over a year ago and it has helped so much with hair loss. Skin and nails look so much better. I subscribed to the yearly plan and they never miss a beat on the shipping. I can always count on WiVi to get my supplements to me on time.

We've used this product for several years and it has helped to keep us healthy amidst so many issues that we come into contact with on a daily basis. At our age this product brings peace of mind‼️

Thank you for providing decent vitamins/supplements at a decent price!
