    which is best vitamin?
    A shopper

    Best Answer:  First, one must distinguish between micronutrients and macronutrients, and within the realm of micronutrients, some are vitamins, some are not. There is no useful answer to that question. I recommend Wikipedia for a better understanding of the term :"vitamins". NAC is considered to be a precursor for glutathione, and glutathione is a substance your own body can produce that acts as an anti-oxidant and thereby acts as an anti-inflammatory agent. I take it in very large amounts daily, almost at the level of micronutrients.

    How and who test this product?
    A shopper

    Best Answer:  The Vitamin Shoppe is very diligent about testing each lot of all of our raw materials for identity, purity, strength, composition, and contaminants before they can be used in the manufacturing of a Vitamin Shoppe brand supplement. Finished products are also tested at random by FDA audited, independent third-party laboratories to ensure that label claims are being met. Our manufacturers adhere to current good manufacturing practices (cGMP) and perform quality control checks throughout the entire manufacturing process.

    Best Answer:  No

    What is shelf life if buying 200 capsules using one a day?
    A shopper

    Best Answer:  The usable shelf life is years, so 200 days will be no problem. Over time, you may notice a whiff of vinegar. That is just NAC breaking down into its components, L-cysteine and acetic acid. Aspirin does the same thing, breaking down into acetic acid and salicylic acid.

      Ubiquinol CoQ-10 - Helps Energy Production, Supports Cellular
      • Promotes cardiovascular health and energy production
      • Offers antioxidant support
      • Especially beneficial for those taking statins
      • Free of gluten, dairy, and nuts

      Ubiquinol is the active form of coenzyme Q10—otherwise known as CoQ-10. In addition to being an essential component for energy production, ubiquinol also supports cardiovascular health and protects your cells against free radical damage. However, your ability to convert CoQ-10 into ubiquinol can decline with statin use and age.

      These once-daily The Vitamin Shoppe® brand softgels contain 50mg of ubiquinol to promote your CoQ-10 levels and support overall heart and cellular health.

      Frequently Asked Questions

      What are statins?

      Statins are drugs that can help lower cholesterol levels.

      How can an ubiquinol supplement benefit people who take statins?

      Statin medications may deplete naturally-occurring coenzyme Q10 in the body. Supplementing with The Vitamin Shoppe® brand Ubiquinol CoQ-10 softgels help replenish CoQ-10 levels and may help prevent statin-induced depletion.
