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.

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.

Great Product for the price
Very easy to take. Tastes good and you can control the dose. Just what my doctor wants me on. Price is good as well.

Pretty good, needs better method of measurement
I decided to give a liquid form of B12 a try since my usual sublingual by Douglas Labs was often unavailable. This is a decent alternative - taste is fine and I like that it’s 3rd-party tested. Hard to say whether it gives me more/less/same energy as my other B12 but I figure it can’t hurt me to continue using. The one downside of this product is its method of use. The dosage is given in number of drops and the dropper doesn’t have any sort of method of measurement. So if you are dropping this directly in your mouth, it’s hard to tell if you are using the correct dosage. I wish the dropper had a graduated measurement so you knew exactly how much to suck up into it, and then dispense directly in your mouth.

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!

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.

There is no way to measure how much you put into your body
Only been on it for a couple of days, but it seems to be working okay. I'm not sure I would buy it again only because there are no measurements at all anywhere on the dropper. So when 1000 mg per drop that's what it means.There are no lines at all even to say this is 5,000 milligrams. No reference whatsoever. I may even return it anyway.
