Product analysis

47 out of 100

Source of Life Mini-Tabs supplies a broad mix of nutrients that can help fill dietary gaps and support normal energy use. Unclear proportions across its mixed ingredients make the full formula harder to compare.

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

Nutrient Quality50

Several vitamin forms are clearly identified and favourable, including folate and vitamins D, E and K. Some mineral mixtures have unclear proportions, while quality remains uncertain for many of the additional ingredients.

Ingredient Transparency72

Every listed amount and many forms are disclosed. The mixed ingredients lack clear proportions, limiting a full breakdown of the formula.

Value For Money29

The product costs relatively much in many nutrient and ingredient comparisons. Vitamin D offers more moderate value, while information for several other ingredients is insufficient.

Customer Satisfaction82

Customer ratings are positive across a large number of responses. That gives the satisfaction picture a broad base without proving effectiveness or safety.

Product Focus0

The clearest purpose is filling nutritional gaps rather than supplying extra benefits when intake is adequate. A very long ingredient list and many goals make it difficult to identify a focused purpose.
