Pro Formula Whitening Gel Pen

Breakdown

1 ingredient to avoid

GuruNanda Pro Formula Whitening Gel Pen scores 75/100 on Tallow — our clean band. That number comes from what is on the label: the ingredients, how processed it is, and what it is packaged in. It is not a verdict on your diet — Tallow does not weigh calories, portion size or how often you eat it, so a high score means the ingredients are clean, not that the food is unlimited.

GuruNanda Pro Formula Whitening Gel Pen lists 7 ingredients, starting with Glycerin, Propanediol, Water, Hydrogen Peroxide and Carbomer. Ingredients are listed in descending order by weight, so the first few make up most of what you are eating.

At 75/100 GuruNanda Pro Formula Whitening Gel Pen sits in our top band, among the better teeth whitening we have scored. A higher-scoring option in teeth whitening is La Sante 100% Natural Charcoal Teeth Whitening Powder at 100/100.
