My pediatrician is very holistic oriented. She recommends various supplements as well as a delayed vaccination schedule for those who vax. So, I was really surprised that when I came to see her after the birth of my fourth child, she told me to supplement with Vitamin D even though I was breastfeeding. Haven't supplemented with any of my other kids. She recommended these Carlson drops (also good for my older kids). They work great. I simply put a drop on my just washed finger, and my little one sucks it off. Easy as can be. The whole bottle will last a year with one child, but as my other kids use the drops as well, not as long. Carlson is a great Brand that has a wonderful reputation. I feel very comfortable giving these to my children.

Been taking this for about six weeks. Energy is more consistent and I feel less sluggish in the afternoons. Happy with the purchase.

Took this for a month and didn't notice much change. Might just not work for me personally.

Third-party tested, clean label. That's what I look for first. Actually works too, which is a bonus.

Switched from a more expensive brand and honestly can't tell the difference in results. Saves money.

It's fine. Did what I expected, nothing more. Might try other brands before reordering.
