Review: It’s tasty and easy, two drops in more than enough - Some of the other reviews are saying that this doesn’t have a flavor. But as someone with very sensitive taste buds, I can assure you that it does but it’s not a negative flavor it’s very sweet and pleasant. With that being said, it works incredibly well so well in fact that I took it at 4 PM like an idiot and stayed up till five in the morning, I don’t recommend doing so. It’s also as you might be able to tell dark red, which had me and my mother and Fitz of laughter because every time we took it, we look like we took a swig of blood which was mildly unsettling. And if you were like me and wear retainers, obviously make sure to remove them prior to taking this, but after taking it, make sure to take a swig of water. Otherwise, your retainers will be stained a light pink . With that being said, I love this B12, especially since I deal with a methylating disorder, which is a disorder that basically means my body doesn’t process vitamins the normal way and so I need liquids more so often than solids and it’s worked very well in improving my vitamin levels , in this case, obviously B12.
Review: No complaints, will order again! - I’ve tried a few different B12 supplements, and this is the first one that doesn't make me feel weird. It seems like a very high-quality product with good ingredients. Even though I'm new to this specific brand, I'm happy with it and plan to keep using it.

## Features

- 𝐌𝐄𝐓𝐇𝐘𝐋𝐀𝐓𝐄𝐃 𝐕𝐈𝐓𝐀𝐌𝐈𝐍 𝐁𝟏𝟐: Our practitioner-recommended formula is made with non-Chinese-sourced Methyl B12 because it's essential for supporting energy production and detoxification, as well as brain & nervous system health, and MTHFR enzyme status.
- 𝐀𝐃𝐕𝐀𝐍𝐂𝐄𝐃 𝐅𝐎𝐑𝐌𝐔𝐋𝐀 Containing a potent, biologically active form of Methylcobalamin, a mitochondrial form of Adenosylcobalamin considered an active "coenzyme" that is utilized directly in B12-dependent enzyme reactions in the body, and a protector form of Hydroxocobalamin that readily converts to Methylcobalamin, our Dr. recommended B12 liquid vitamins are truly unlike any other on the market today.
- 𝐏𝐑𝐄𝐌𝐈𝐔𝐌 𝐐𝐔𝐀𝐋𝐈𝐓𝐘: We never use fillers, excipients, or flow agents in our supplements, including our vegan B12 vitamin supplement. We always promise to put quality first with absolutely no exceptions. We do not use Chinese-sourced ingredients because their quality, potency, and authenticity are often questionable.
- 𝐅𝐎𝐑𝐌𝐔𝐋𝐀𝐓𝐄𝐃 𝐀𝐍𝐃 𝐏𝐀𝐂𝐊𝐀𝐆𝐄𝐃 𝐈𝐍 𝐓𝐇𝐄 𝐔𝐒𝐀: Discussed on The Joe Rogan Experience with Gary Brecka as an optimal choice to regain ideal health. Formulated and packaged in NSF-certified facilities right here in the USA, our third-party tested non-GMO sublingual B12 supplement meets the FDA's strict cGMP guidelines.
- 𝐀𝐁𝐎𝐔𝐓 𝐔𝐒: Pure TheraPro Rx was founded in Denver Colorado to formulate and manufacture the highest quality supplements available on the market today. Purity is our priority, which is why we insist on using patented, clinically studied ingredients, and never utilizing fillers, flow agents, excipients, or ingredients sourced from China. We also never use dairy, gluten, corn, soy, or other common allergens in any of our class-leading, practitioner-recommended formulas.

## 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
