Product analysis

50 out of 100

Glow can help fill nutrient gaps that affect normal immune function, metabolism and hair health. Its undisclosed blend makes the added ingredients harder to assess.

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

Nutrient Quality49

Folate, iodine and selenium use favorable identified forms. Other form comparisons are less clear, and the vitamin K type and blend contents are not specified precisely.

Ingredient Transparency77

All declared amounts and most forms are disclosed, making much of the serving checkable. The blend contents remain undisclosed, and some form details are incomplete.

Value For Money31

Several nutrients offer limited value, with selenium, chromium and riboflavin relatively costly for the amounts supplied. Value for many accompanying nutrients remains uncertain.

Customer Satisfaction73

Customer ratings are generally positive. The more modest review base may reflect a narrower range of experiences.

Product Focus16

The main role is filling nutritional gaps that affect normal immune function and metabolism. The declared 105,000 mcg vitamin D serving is exceptionally high and needs verification before use.
