Product analysis
Source of Life Prenatal supplies iron, folate and B vitamins that may help maintain normal energy and immune functions when nutritional needs are unmet. An unnamed blend with no stated quantity makes the full formula harder to check.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality38
Vitamin B5 and manganese use favorable forms, while several other nutrient forms remain difficult to judge. The unclear thiamin and iodine forms and unidentified blend limit confidence in consistent quality.
Ingredient Transparency73
Most ingredient amounts and forms are stated, helping you review much of the formula. The unnamed blend lacks a quantity and ingredient breakdown, preventing a complete check.
Value For Money42
Value is mixed, with a favorable price comparison for phosphorus and a less favorable one for vitamin B5 and bromelain. Several other ingredients lack enough price information for a complete comparison.
Customer Satisfaction79
Customer feedback is highly positive across a few hundred ratings. The response gives a useful picture of satisfaction but cannot establish suitability during pregnancy.
Product Focus10
The clearest contributions involve meeting nutrient needs related to energy, immune function and normal metabolism. The broad ingredient range and unidentified blend make the formula less focused and prevent a complete check of its scope.

Iron at 18 mg, folate and vitamin B12 help maintain nutrient status relevant to fatigue and weakness. The other B vitamins support normal energy metabolism, and magnesium at 200 mg adds nutritional support. These contributions are most useful when intake is inadequate and do not imply a stimulant effect.

Zinc, iron and biotin can matter when deficiency contributes to shedding; they do not establish routine regrowth with adequate intake. Vitamin C supports normal collagen production and iron absorption, and folate supports cell division. Vitamin A received recognition, but ordinary cell functions do not establish regrowth and excess can contribute to hair loss. The small vitamin D and B12 amounts did not count.

Vitamin A supports protective barriers, while zinc supports normal immune-cell function. Folate and vitamins B6 and B12 help restore immune-cell function when intake is deficient; larger amounts do not establish extra benefit once needs are met. Vitamin C and vitamin D are present in amounts too small to contribute to the saved findings. Iron is relevant when deficiency impairs immune function, rather than as routine infection prevention.
How this product is rated for Immunity
Ingredient fit60
Zinc is a relevant part of this formula’s immune connection. Zinc supplies a meaningful part of the serving’s immune connection, while the included amounts provide only partial overall coverage of the saved comparisons.

Iron can help restore heat production when iron-deficiency anemia has reduced it; this is a conditional correction rather than a boost above normal metabolism. Iodine also supports thyroid hormone production when intake is low. B vitamins support normal use of food for energy, but additional amounts have not been shown here to increase whole-body energy expenditure.
How this product is rated for Metabolism Support
Ingredient fit69
Thiamin and the other nutrients have normal metabolic roles, but those roles do not establish a routine increase in energy expenditure. The formula’s ingredient amounts provide nutritional context rather than proof of a metabolic boost.
Goal fit
Thiamin and the other nutrients have normal metabolic roles, but those roles do not establish a routine increase in energy expenditure.
Dose adequacy
Some declared amounts are small or unresolved, limiting their contributions; the other amounts still do not establish a thermogenic effect.
Pathways0
No direct energy-expenditure pathway receives support in the saved findings. The findings do not establish broad thermogenic coverage.
Depth
No direct energy-expenditure pathway receives support in the saved findings.
Breadth
None of the examined areas has sufficient contribution for broad coverage.
Evidence100
Thiamin leads the saved findings, while the supplied scientific context does not establish a routine energy-expenditure boost from supplementation. Deficiency correction remains a distinct conditional role.
Evidence strength
Thiamin leads the saved findings, while the supplied scientific context does not establish a routine energy-expenditure boost from supplementation.
Studied preparation
The counted ingredients meet the saved preparation criteria; that finding does not establish a preparation proven to raise everyday energy expenditure.
Formulation logic100
The counted ingredients have their required partners and no evaluated conflict was identified. Meeting amount thresholds does not establish a proven thermogenic regimen.
Partner coverage
The counted ingredients do not lack a required partner in the supplied findings; this does not demonstrate a combined thermogenic benefit.
Conflicts
No evaluated ingredient conflict was identified in the supplied facts.
Effective doses
The counted ingredients meet the comparison’s amount threshold; this is not evidence of a proven thermogenic dose.
