Vitacost is an online health food store that offers a wide range of products, including vitamins and supplements, food and beverage, beauty and personal care, sports and fitness, herbs and botanicals, diet products, and household, family, and pet items. Vitacost also has its own brand of supplements, including Vitacost brand, Synergy, and ROOT2, which are known for delivering high-quality nutritional support at an exceptional value.

Regarding the ingredients or materials used in Vitacost products, the blog post "Supplement Fillers and Additives: Know Your Products" explains that supplements contain "other ingredients" that can be classified as either a dietary ingredient, a functional ingredient, or a food additive. These ingredients are scrutinized for function, toxicity, and safety by the FDA and approved as a food ingredient when the evidence strongly precludes a chance of harm when consumed as expected. Some common binders and stabilizers in supplement formulas include plant-derived cellulose and oil-based stearic acid, while some additives like silicon dioxide absorb moisture and help ensure that components don’t stick together or to machinery.

As for positive and negative details about Vitacost products, the website does not provide specific information on individual products. However, Vitacost has a quality guarantee for its brand, which has been dedicated to providing the highest quality health and wellness essentials at the best prices since 1999. Additionally, supplement testing helps manufacturers confirm that formulas are correct and claims are valid, which can help customers feel confident and safe.
