WORTH EVERY PENNY
I’ve been taking Pure TheraPro BioActive B12 for a few years and find it very effective. It’s pricier than other brands but worth every penny. other brands, but worth the cost.

Good B-12 product, but expensive.
I actually liked this B-12 and feel like it was effective. However, its expensive so I deducted a star and probably will seek something more cost effective for me.

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!

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.

I did my homework
Do your research on B12 and it will be logical choice it this. I just got this and tried it sublingual. The taste was not strong and it absorbed quickly. I will write back an updated review if this isn’t what the research has written.

It works
I use this product as a part of my morning routine and I can definatly confirm that it does work. It gives me a natural boost of energy that is easily sustained through my day. After brushing, I place the drops under my tounge and let it sit for a few minutes before swallowing for maximum absorption.
