Review: High-Quality B12 Supplement That’s Easy to Take - This B12 supplement is a great option if you’re looking for a clean easy-to-use formula without unnecessary fillers. I have noticed an increase in energy and better mental clarity. The liquid format is a nice texture and makes it simple to take. The dropper allows you to control the dosage easily. It absorbs quickly when used sublingually which is convenient if you prefer not to take pills. The combination of different forms of B12 is a nice touch, and it feels like a more complete approach compared to basic supplements. The taste is quite mild and not overpowering which makes it easy to use consistently. My whole family has no issues with the taste, my toddler says it tastes like strawberry. It’s also reassuring that it’s made without common additives and is produced in certified facilities. I think that this is a solid supplement that’s simple, well-formulated, and easy to incorporate into a daily routine.
Review: Better than B12 injections!!! - More effective for me than injections! I was *extremely* low on B12 and I did injections for almost a year with hardly any noticeable difference, neither in the way I felt nor in my bloodwork labs. I read about this product in a group that is for chronic illness and someone mentioned that she used five drops per day and it significantly raised her levels. So I did the same (I could actually feel a difference in my energy within a few days) and two months later I did another round of bloodwork (I had stopped doing the injections when I started using this because I was sick and tired of the needles and they weren’t even helping) and my levels went from extremely low to within normal range!! I continued on to get my levels higher in that normal range and six months later, it was well past that normal range and considered extremely high. So, no doubt about it THEY WORK!!! I now do only three drops per day. My doctor was absolutely amazed at how well these have worked and has recommended it to all of her patients who were getting B12 injections. I’m not sure why these teensy weensy drops work so much better than intramuscular injections but they are absolutely amazing and are one of the few supplements I take that I KNOW without a doubt actually do something and are worth purchasing repeatedly.

## 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 activity.
- 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.

### ⭐⭐⭐⭐⭐ Teeny Tiny Bottle Barely Lasts A Month!!
*by C***N on 11 March 2026*

"Pure TheraPro BioActive Vegan Methylated Vitamin B12 Sublingual Liquid Methylcobalamin, Hydroxocobalamin & Adenosylcobalamin 1,000 mcg per Drop (5 Drops = 5,000mcg / 2 Month Supply) 10 ml" I ordered this product, because I have had B-12 Deficiency for more than 25 years. I have to inject B-12, but I wanted to add an oral supplement to see if I could somehow boost my b-12 levels. This product had a lot of great reviews, which is why I ordered it. I trusted the reviews that I read. I'm on my 2nd order, and once delivered I fell hard for the sweet taste of the sublingual drops. That made it a pleasant experience. I did use up my first bottle, and truthfully, I can feel somewhat of a difference. As another reviewer observed, however, the bottle is TEENY TINY. Not one of my favorite features. It also is supposed to last 60 days. NOT A CHANCE! That is just untrue. But, I've committed to stick with it and see how it works for me long-term. So far, I'm enjoying using it. But it barely lasts a month.
