Review: Along with the other well known benefits of L-theanine, this microlingual helps me sleep. The one objection I have to purchasing it on desertcart is the large FNSKU sticker placed on the box. This happens with other supplements I have bought on desertcart as well. And they are stuck fast so that removing them, removes the information under it.

## Features

- PROMOTES HEALTHY HAIR, SKIN & NAILS - Superior Source Biotin helps support Healthy Hair, Nails and Skin. Additionally, Biotin is necessary for certain enzymes to work properly. Biotin is a water-soluble B Vitamin required for the body's protein, carbohydrate, and fat metabolism. As the body can’t make or store biotin, a daily dose will help maintain proper levels in the body.
- JUST PURE INGREDIENTS – Non-GMO, gluten-free, preservative free, sugar free, dye free; no unwanted fillers, no additives, no excipients, no Magnesium Stearate or Silica. Other vitamins require lots of binders to hold them together. Our Micro tablets only contain the pure active nutrients and other necessary natural ingredients.
- MICROLINGUAL VITAMINS – Melts that dissolve instantly with no pills to swallow. Superior Source pioneered the world's best delivery system of MicroLingual vitamins that melt fast under the tongue and give rapid absorption for the body.
- GMP CERTIFIED QUALITY - We test all incoming raw materials for the active ingredients, heavy metals, GMOs, and microbial contamination through a third-party certified laboratory. Once manufactured, the Superior Source MicroLingual tablets go for additional potency, contaminant and purity testing. Once we confirm that the finished product meets or exceeds our GMP compliant quality standards it is released to you.
- SUPERIOR SOURCE, THE COMPANY THAT CARES - Creating pure MicroLingual vitamins since 1998 in our family-owned manufacturing facility. We are a company built from love for health, wellness, fitness, nutrition, and the need for a better life.
