The Truth
5 Stars
The Truth
I am anemic and usually have very low energy and find it hard to concentrate throughout the day. I also take naps VERY often. This has been a game changer. I just take one pill first thing in the morning and I have so much energy for the rest of the day and I get so much done! These are easy to swallow, I find them already starting to disintegrate before I can take a drink. I didn’t notice an after taste. There is a huge cotton ball to prevent them from spilling out. I give this a 10/10. Will order again.
