Iron is an important mineral, helping deliver oxygen from our lungs to our entire body. Without adequate iron stores, you may not be able to get enough oxygen delivered to all your tissues, which could result in fatigue, muscle weakness upon exertion, pale skin and inability to stay warm.
According to the CDC, 1 in 10 women is at risk for an iron deficiency.
Low iron can be a result of low dietary intake, poor absorption and/or excessive blood loss over time, increased demand during pregnancy.
Obtaining enough iron is often easier said than done, especially if you’re on a vegan or vegetarian diet. Additionally, it’s important to note that iron relies on other nutrients, like vitamin C, to properly absorb into the bloodstream.
We also offer Blood Builder Minis (a convenient mini tab version of Blood Builder) and Blood Builder Liquid Iron One Daily (a convenient, once-daily liquid iron format).

"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."
"Tablets are perfectly sozed and very easy to swallow. No constipation or upset stomach. Feeling a lot more energized and can not wait for my f/u visit for my repeat blood work. Need to get my iron level way up!"
"Love this supplement! No upset stomach! No constipation. Consistent daily use has increased my iron levels and energy. It’s been a game changer for me."
"Awful- after 2 doses, immediately made me very ill. No response from customer service when I emailed about a return."
"My doctor recommended this product due to my extremely low iron and ferritin. I've been taking consistently for years now and have seen improvement. I tolerate this well. I now buy as many of my supplements as possible from MegaFoods."
"This is the one iron supplement I have found that doesn't have side effect no one needs, constipation!"
"I’m Absolutely Blessed With This Project And Will Continue To Order When It’s Time To Reorder"
"We take this because we're regular blood donors to replenish our iron stores! It's easy to take and easy on our stomachs."
"This product absolutely saved me. It was the only iron I tried that didn't constipate me and seems to be absorbing well. I used to be dizzy constantly, anxious, exhausted, losing hair, had random blood sugar issues despite no diabetes, and even trouble swallowing at some point. I was constantly overstimulated and couldn't even handle listening to music anymore, and of course, could not focus or remember things. . . Some of the weirdest issues I've experienced. I finally got a blood test and my ferritin was 9. I've been taking this consistently for about 3. 5 months and ALL above issues went away. I noticed improvements in the first 2 days, but even more at about 2 weeks. About to get my levels checked. I cannot express how thankful I am for the scientists who figured out this formula all with clean ingredients."
