Product analysis
Source of Life Tablets offers broad nutritional support for normal energy metabolism, blood formation and immune function. Its relatively high cost and undisclosed blend details make it less appealing for someone seeking a specific nutrient.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality50
Several vitamins use clearly identified forms, including D3 and a readily usable folate form. Other forms and mixed-source proportions are less clear, so quality varies across the formula.
Ingredient Transparency72
Ingredient amounts and many forms are listed. Several blends omit their component proportions, and some do not identify individual components, limiting a full understanding of the contents.
Value For Money29
Many nutrient portions are relatively costly for the amounts supplied. The broad formula therefore offers limited value if you mainly want one or two nutrients.
Customer Satisfaction69
Customer feedback is positive, though the number of ratings is small. The limited review base gives less breadth to the satisfaction picture.
Product Focus0
The formula spans many nutritional goals, with benefits clearest when it fills a dietary gap. Its extensive ingredient list and undisclosed blends make it difficult to judge as a targeted supplement.
