Sensitive to most supps, however...

These have been amazing for me! It's hard for me to find supplements which provide the crucial B vitamins, that I don't react poorly to (wired feeling, headache, just generally off... basically can't adhere to these even though I want to!). This is a great way for me to get some of those important elements in. I feel great on this, so relieved and happy! Doesn't taste bad at all and now I have my mom and husband taking them as well. I split the dose in am and early afternoon. Recommend for those that are struggling to find supplements that don't make them feel "weird!" THANK YOU!

Great product

I have tried other organ supplements from popular nutritional companies, but this is the only one that has helped my iron levels increase. I really struggle to absorb enough iron, and this supplement is a definite help! I take it every day and highly recommend it!

Hi Donna, Thank you for sharing your experience with us. It's great to hear you are noticing a difference in your iron levels. We appreciate your support to Adapt Naturals!
