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.

Good B12
After careful research, this is the choice of B12 I landed on. It doesn’t have cyanocobalamin which was a plus for me. The ingredient seem clean and vegan. The taste is almost nonexistent. Most importantly it has the three types of b12 I need in their respective quantities. The bottle is small but I am positive I will see good results with this product. I just started using it though.

New supplement regimen while on chemo
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!

Teeny Tiny Bottle Barely Lasts A Month!!
"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.

Disappointed
Good flavor, gave me energy, but unfortunately it did not last more than 30 days. Too bad, I will not be reordering this product.
