Charlotte, North Carolina (March 25, 2015) - Given the number of variations in e-liquid ingredients available on the market, how should consumers or wholesalers choose? An [b]RTS Vapes review[/b] recommends consumers look for products with quality controls such as United States Pharmacopeia (USP) grade or Kosher Certified. This is to ensure that the ingredients are safe and of the best quality.

The USP is the official authority for all prescription and over-the-counter drugs, food ingredients, and dietary supplements manufactured or sold within the country. It sets the standards for strength, quality, purity, and consistency of these products and is enforceable by the Food and Drug Administration. Its standards are recognized by more than 140 countries. Bypassing the guidelines means it’s likely for the ingredient to be substandard, possibly containing harmful contaminants.

One key ingredient of e-liquids is vegetable glycerin (VG), often accounting for about 50-90% of the mixture. It’s responsible for producing vapor during exhalation. It is estimated that 95% of all e-liquids available have VG as a base. As an RTS Vapes review would show, compared to propylene glycol, VG produces more vapor and is milder on the throat.

Along with the necessary supplies to make e-liquid, RTS Vapes offers 100% pure USP Kosher certified VG. Aside from the ingredient’s high vapor production, certified VG is also a very good alternative for those allergic to propylene glycol.

RTS Vapes offers the best deal for USP grade VG. Aside from enjoying low prices, purchasers may benefit from discounts through the company’s MyRewards program. Plus, qualifying orders of $75 or more ship free within the U.S. Standard shipping rates apply for International orders.
