Great vitamin capsules
Most multivitamins have an awful odor that turns me off from using them. Each of these capsules encases the contents in a lining that blocks the smell and is easy to swallow, which then dissolves in the stomach. It's a great solution for me.

Life changing for me!
I never write reviews but these are AWESOME! I have had low iron for about 10 years and nothing I’ve tried in the past (changing my diet, other multi-vitamins, prescribed iron supplements, etc.) has ever gotten rid of the fatigue that comes with it. I started taking these about a month ago and I feel like a brand new person! I can get through the day without taking a nap or multiple, which has bettered not only my sleep schedule but my productivity all around! I could not recommend enough. They do have a nasty smell but I just breathe through my mouth until I’ve swallowed it lol. The smell is 100% worth the outcome in my opinion.

Ordered multiple times and am pleased!
I got these when one a day stopped making the gelcap minis that I loved and used for years. I prefer gelcaps over tablets for better absorption, and these don't disappoint at all. They're good quality, as I notice the difference when I don't take them. They're easy to swallow despite being a somewhat larger capsule, and very comparable in contents and values to the ones I took before. I feel better when I take them, and that's enough for me. Shipping was fast and they arrived undamaged, every time I've ordered them.

The Perfect Liquid Gel-Cap Multivitamin
My doctor asked me to take a multivitamin in liquid form, as the vitamins are absorbed so much better than with a pressed-powder tablet. These are not easy to find locally! I have been using these vitamins for quite a while and order more when I am getting close to running out. I was pleased to find them on Amazon at a good price. I had bought others online, but the price was considerably more for a comparable product. There is no aftertaste, and they are easy for me to swallow. They are large, so they may not be for everyone, but they solved a problem for me.
