Cons
- An iron supplement is not a general energy product; added iron may be unnecessary or unsuitable for some people.

MegaFood Blood Builder is a popular iron supplement with a straightforward label story: 26 mg of iron in one daily tablet, paired with vitamin C, folic acid, B12, beets, and organic oranges. MegaFood calls it the brand’s top-selling iron supplement. Its strongest feature is how easy it is to evaluate from the product page: the amount and daily serving are clearly listed.
The key question comes before the bottle: do you need supplemental iron? This is a targeted nutrient, not a general-purpose energy booster. Iron status is assessed with health history and testing, and the right amount varies by person. If you have low energy or think you may be low in iron, ask a healthcare professional before adding a 26 mg supplement.
What is in one serving
MegaFood lists 26 mg of iron per serving, using iron bisglycinate, and directs adults to take one tablet daily. The formula also includes vitamin C, folic acid, B12, beets, and organic oranges. The additional nutrients give the formula more context than a single-ingredient iron tablet, while the iron amount remains the main reason to choose it.
The brand calls Blood Builder its top-selling iron supplement. The product page’s rating components displayed inconsistent review totals, so we do not repeat a star average here. Its best documented popularity signal is the brand’s own top-selling label; that cannot tell you whether you need more iron or will tolerate this tablet.
Price and current offer
The official product page listed the 60-tablet bottle at $23.99 on October 4, 2026. MegaFood advertises 10% off Subscribe & Save orders, which is a recurring purchase with a separate renewal schedule. There is no WWIL customer code listed. The page also advertises free US shipping on orders over $50, so a single bottle may not reach the free-shipping threshold by itself.

Who should consider it
Blood Builder may suit an adult who has been advised to increase iron intake and wants a single daily tablet with a clearly stated amount. It is vegan and the brand says it is made without the top nine food allergens, but check the current label if you have an allergy or a specific dietary requirement.
Who should check first
Iron is not a universal supplement. Excess iron can cause stomach upset and other harms, while iron supplements can interfere with medicines such as levothyroxine and with other supplements such as calcium. People with conditions that affect iron storage should be especially careful. The NIH Office of Dietary Supplements iron fact sheet summarizes known risks and interactions; discuss your own situation with a clinician or pharmacist before starting.
Verdict
MegaFood Blood Builder is easy to understand as a product: one tablet, 26 mg of iron, plus vitamin C, folic acid, and B12. The brand’s top-selling label suggests real buyer interest, and the current 60-tablet price is clear. Our recommendation is conditional: it is worth considering when a healthcare professional has identified a reason to supplement iron. Popularity, a promotional price, and an energy-focused headline are not reasons on their own to add iron.
Who it's for
An adult whose clinician has recommended an iron supplement and who wants a clearly labeled, once-daily tablet.
Who should skip it
You have not established that you need added iron, have been told to avoid it, have a condition that affects iron storage, or take medicines that may interact.
