Reliable brand
This is a good product. It has no after taste, it’s also easy to swallow. I had no gut issues or bowel issues while using. I noticed an energy spike and that’s a good thing.

Great value
The capsules are so small so it is easy for anyone to swallow, the quality is great especially for the price! If I forget to take one my body will definitely remind me to. Great source of natural energy. No bad taste

So far so good
I’ve been using the vitamin for 2 weeks now. I’m also taking some other vitamins along with this one. So far, I see no negative effects. I do see a change in energy levels during the day. I would normally take a nap on my off days but, I haven’t felt the urge to do that lately. I also noticed frequent bathroom visits. Water is my best friend so I know I’m not dehydrated. The vitamin is giving nutrients to the body so I guess it’s working and just cleaning me out.
