Review: Definitely something needed in my health regimen. For 6 months have been trying to keep pace with chemo. Have been taking 100 mcg of Vitamin B12 in pill form two or three times a day. Then a Friend suggested I look into the liquid dose form. Bioactive B12 Full Spectrum in liquid form provides maximum absorption. After the first recommended dose, I’ve done two activities today: a 3K walk as well was simple pool laps for 45 minutes. Impressed that I feel energized from the activity versus extreme fatigue! Will keep track of my body’s response over the next 7 days. Stay tuned!
Review: Ongoing subscription. Always happy with this product.

## Questions & Answers

**Q: What country is this produced?**
A: All products are made in the USA; no raw materials are sourced from China. Unlike most other supplement companies, the ingredients that go into our
supplements are not selected based on cost. Instead, they are selected based on purity (to ensure contaminants such as microbes and heavy metals comply with regulatory GMP requirements), potency, and chosen based on successful scientific research. Patented ingredients are utilized when appropriate.

All of our products are third party laboratory tested post-production for heavy metals and other contaminants. We are also cGMP Certified (Current Good Manufacturing Process) with strict FDA compliance. These are a few of the measures Pure TheraPro Rx uses to ensure the consistent quality and potency of our formulas. In addition, our production facility and formulas have physician and scientist oversight. We are also meticulous to ensure our supplements are free of all common allergens. In other words, what is on the label must be in the bottle - no fillers, no excipients, no junk.

**Q: Seller answer only please... does this product contain any synthetic ingredients?**
A: Our BioActive B12 does NOT contain any synthetic ingredients. All the ingredients are naturally derived either as chelates or through fermentation - fermentation is a natural synthesis.

**Q: What is your vegetable glycerin derived from?**
A: The vegetable glycerin is derived from coconut oil.

**Q: Can this be used for 3 year olds?**
A: Can anyone respond if you've actually found a methyl-B12 safe for 3-year-olds?  This would be much appreciated -- thank you
