61 out of 100

Iron Complex offers a low-cost iron contribution alongside vitamin C and B vitamins. Unspecified folate and botanical preparations make the wider combination harder to compare.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality34

Iron and several vitamin sources are named, but their combined quality remains uncertain. Folate and the two botanicals lack specific forms, limiting preparation comparisons.

Ingredient Transparency81

The listed ingredient amounts are disclosed, making serving comparisons possible. Folate, dong quai and red raspberry lack specific form details.

Value For Money62

The iron contribution offers favorable value at the serving cost. The value added by the accompanying vitamins remains uncertain.

Customer Satisfaction85

Customer ratings are very favorable. The large number of ratings provides a broad picture of satisfaction.

Product Focus65

The formula centers on iron with accompanying vitamins and botanicals. Its several active ingredients make their individual contributions less simple to separate.

Iron may help when low intake is contributing to diffuse shedding, or hair loss spread across the scalp. That benefit depends on correcting a shortage; extra iron doesn't offer a demonstrated regrowth benefit when you already get enough. The amount in a serving cannot tell you the cause of your hair loss or the replacement amount you might need.

How this product is rated for Hair Health

Ingredient fit68

Iron may help shedding linked to a shortage, rather than reliably increasing growth when intake is adequate.
Goal fit
Iron provides the nutrient connection to hair; other actives broaden the formula beyond this goal.
Dose adequacy
Vitamin B9 (Folate): 333 mcg DFE per serving; Iron: 27 mg per serving; Vitamin B12: 50 mcg per serving.

Pathways0

The connection here concerns nutrient roles rather than a demonstrated effect on hair-fibre structure, androgen signalling or stress-related hair changes.
Depth
The connection here concerns nutrient roles rather than a demonstrated effect on hair-fibre structure, androgen signalling or stress-related hair changes.
Breadth
Nutrient roles don't imply broad action on the different causes of hair loss.

Evidence78

Correcting low iron can matter for shedding; routine regrowth when iron intake is adequate is unsupported.
Evidence strength
Correcting low iron can matter for shedding; routine regrowth when iron intake is adequate is unsupported.
Studied preparation
The declared nutrient forms don't by themselves guarantee better hair outcomes.

Vitamin B12 · 50 mcgIron · 27 mg

Iron can help address fatigue associated with iron deficiency, including selected cases of low iron stores without anemia. Folate and vitamin C also contribute through nutrient sufficiency, with fatigue relief relevant to low intake or deficiency. These roles do not establish added energy when nutrient status is adequate. B12 is present below the saved contribution threshold, and the iron trial findings do not establish the same fatigue effect for this chelated preparation.

How this product is rated for Energy

Ingredient fit82

Iron, folate and vitamin C contribute alongside ingredients outside the energy focus.
Goal fit
Iron, folate and vitamin C contribute alongside ingredients outside the energy focus.
Dose adequacy
The credited amounts largely meet saved references; B12 is below the contribution threshold.

Pathways0

The contribution concerns nutrient sufficiency; no listed direct alertness, exercise or stress-fatigue pathway receives coverage.
Depth
No listed direct energy pathway receives coverage from the credited nutrients.
Breadth
No listed pathway reaches the coverage threshold.

Evidence98

Iron provides the strongest recognized evidence contribution at its saved amount. Its practical benefit remains subject to the population and nutrient-status limits described above.
Evidence strength
Iron leads the evidence contribution among ingredients at recognized amounts.
Studied preparation
The credited ingredients meet the saved preparation criterion; this does not establish benefit for every user.

Formulation logic100

The credited ingredients require no missing partner, and no configured conflict was found. All credited amounts pass the saved minimum contribution threshold.
Partner coverage
Every credited ingredient can contribute without a missing required partner.
Conflicts
No configured ingredient conflict was identified.

Iron at 27 mg and folate support nutritional needs linked to fatigue and concentration when intake is inadequate. The 50 mcg B12 serving adds a smaller contribution in the saved assessment; benefits depend on nutritional needs rather than an assumed general boost.
