There is no product guarantee, but HealthAid has a reputation going back over 25 years in the supplement market. Customer reviews are quite split, with over half reporting positive results as promised on the box, and about 30% unhappy with the results of the supplement.


The long reputation of this manufacturer, and the proven ingredients that aid in digestion and remedy bad breath make this comparable to many supplements on the market. The mix of five-star and one-star reviews seem to indicate that this may be a ‘hit or miss’ product that works well for some and not for others. The lack of guarantee is another downside of this product.
