Analysis

iron citrate supplies 25 mg of iron in one capsule. Iron citrate supplies a meaningful amount but is less established for tolerance and absorption than bisglycinate.

The focused serving may help energy and hair when low iron is documented. A vegetable capsule and very low serving cost are useful practical strengths.

No absorption cofactor or blood-cell-support vitamin is included. Iron status and the reason for supplementation should guide duration and dose.

Who is it for
  • Adults with verified low iron
  • People seeking a low-cost vegetable capsule
  • Users who specifically prefer iron citrate
Best for
  • Focused daily iron
  • Budget capsule use
  • Energy support when iron is low

Pros

  • Clear 25 mg iron amount
  • One vegetable capsule
  • Simple single-ingredient formula
  • Very low serving cost

Cons

  • Citrate is not a top-priority iron form
  • No vitamin C
  • No folate or vitamin B12

Warnings

  • Iron citrate may cause constipation, nausea, or stomach discomfort.
  • Use iron for a confirmed need; unnecessary intake can accumulate, particularly in people with hemochromatosis or other iron-overload conditions.
  • Iron can reduce absorption of levothyroxine and some tetracycline or quinolone antibiotics, so separate doses as directed by a pharmacist.
  • Keep iron supplements away from children because accidental ingestion can cause serious iron poisoning.

Nutrient quality

81 Highest impact

A meaningful amount supports focused deficiency correction at low cost. The less established citrate form and targeted-use requirement are the main trade-offs.

.

Ingredient transparency

84 Highest impact

The iron form and amount are specific, with no hidden blend. Intake directions and non-active ingredients were not included in the supplied details.

.

Customer satisfaction

71 High impact

The available satisfaction metric is favorable and the sample provides useful confidence. Specific experience details are absent, so repeated complaints and purpose fit remain uncertain.

.

Value for money

96 Highest impact

Strong active quality and a very low serving cost provide excellent value. The focused formula is competitive without relying on weak extras.

Iron · 25 mg

Iron can reduce deficiency-related shedding when low ferritin or anemia is the underlying problem. Human evidence supports correction of iron deficiency, but extra iron does not promote hair growth in iron-replete users.

The 25 mg amount is substantial and iron citrate is clearly identified. Unneeded iron can cause digestive effects and accumulate in iron-overload disorders, so use should match a documented need.

Iron · 25 mg

Iron can restore energy when deficiency limits hemoglobin and oxygen transport. The capsule supplies a meaningful amount with clear elemental disclosure.

Iron citrate is less preferred than premium chelated forms and the formula includes no vitamin C or blood-forming cofactors. People with adequate iron status should not use iron solely for energy because excess iron can be harmful, and the capsules must be kept away from children due to poisoning risk.

Iron · 25 mg

Iron may improve energy and concentration when iron deficiency limits oxygen delivery, but it is not a general productivity enhancer. Evidence supports benefit in deficient users rather than routine use by people with adequate iron stores.

The 25 mg amount is effective, while citrate is a less established choice than several common iron forms and no absorption cofactors are included. Unneeded iron can cause constipation, nausea, or excess accumulation, so this dose is best guided by confirmed need.

F Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyA+ Value

The 25 mg dose is effective and convenient in one vegetable capsule. Iron citrate is a lower-priority form for absorption and digestive comfort, and no supporting cofactors are present. Its very low serving cost is attractive, but form quality remains the key compromise.

85 Performance

Iron Complex

Advanced Nutrition by Zahler
Ferrochel iron is paired with vitamin C, methylcobalamin, folic acid, and histidine, giving broader disclosed support for energy and hair goals. Its iron amount stays close to the original’s 25 mg. The added nutrients make it less minimal than a single-ingredient iron product.
87 Performance

Vegan True Iron Support

Source Naturals
Ferrochel bisglycinate iron is combined with vitamin C, folic acid, and vitamin B12, with strong iron and energy alignment. Its iron amount stays close to the original’s 25 mg. Cyanocobalamin and folic acid are clearly listed, although other forms may be preferred by some users.
86 Performance

Chelated Iron 18 mg

Bluebonnet
The concise formula uses a clearly identified ferrous bisglycinate chelate and avoids unrelated active ingredients. Its iron amount is lower than the original’s 25 mg. The simpler amount may suit users who do not need a higher-dose or multi-ingredient formula.
77 Budget

Iron 65 mg

Nature Made
The lower serving cost provides a clearly identified ferrous sulfate form. Its iron amount is higher than the original’s 25 mg. The single-active formula keeps the formula similarly focused on iron.
85 Budget

Iron 25 mg

Source Naturals
The lower serving cost provides iron as an explicitly named amino acid chelate. Its iron amount stays close to the original’s 25 mg. The single-active formula keeps the formula similarly focused on iron.

Prenatal Multivitamin/Multimineral with Folate

Spring Valley
The lower serving cost provides iron alongside folate, vitamin C, vitamin D3, zinc, and other prenatal nutrients. Its iron amount stays close to the original’s 25 mg. The iron form is not supplied, and the prenatal focus may be unnecessary for someone seeking iron alone.
