Review: Nice product. Mild flavor . Very effective!
Review: I really like this product. I only have to use 4 drops/day, so it goes a long, long way. Its easy to use. I add it to my Vitamin C effervescent tablet in water every day so I don't have to pop any pills and that way I don't notice the taste either so I can't comment on that. I highly recommend.

## 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

### ⭐⭐⭐⭐⭐ Review
*by H***M on 20 November 2025*

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!
