Blood Builder has done wonders
Blood Builder has done wonders for me. I've been hit with a bad bout of arthritis in 2024 and was put on medication. My count has tipped downward some after maintaining a steady and perfect count since I started the therapy years ago. This month I am due for a retest and follow-up with my Hematologist. There were a few days where I have forgotten to take my supplements which may have contributed to that fact. I have once again been faithful in my scheduling consumption and have no doubt my count has risen to the perfect levels it has maintained since the beginning. Thank you MegaFood. I would like to explore a quality of B12 or a all B complex so any info you can send my way would be great.

Mega food blood builder iron
Mega food blood builder iron supplement is the only one I can take to help boost my iron with stomach problems. My iron is typically on the lower side and this supplement has been just right. I take it on occasions where I feel my iron is low or a day before I donate blood.

Best iron vitamin
I love these vitamin iron pills. They are very gentle on your belly, they have some vitamin c in them which makes it even better to absorb the iron.

I tried a lot different
I tried a lot different irons, and I like that this one does not stain my teeth, does not make me constipated, and does not make me nauseous. I do try to make sure I have something on my stomach or I’m going to eat soon after I take it, but this has been the least problematic iron I’ve tried

The most effective supplement for my RLS (restless legs syndrome). Without this specific formulation I suffer. Yes, iron deficiency as (at least part of) the cause of RLS has been pretty well documented.

I have low ferritin and
I have low ferritin and iron deficiency, and my doctor recommended Blood Builder because it’s gentle on my stomach and I can take it without food. It also has vitamin C to help with absorption, plus B12 and folate to support red blood cell production. My iron and ferritin levels have improved a lot.

Shared this product with my mom as her iron was very low, Her provider wanted her to try some drug store brand supplement. I asked her to try this and when she went back for her test result her iron was in normal range, She showed her provider what she was taking and he is now aware of Blood Builder by Mega Food.
