Customer Reviews
Rated 5 out of 5 by from Terrific Results I tried this product because my B12 level was tested and was found to be very low but still within the "normal" range. My health care provider at that time did not agree that supplementation was needed. I tried this product on my own. I used it two to three times a week. I changed providers and some months later had my blood retested. The level came back at the high end this time! My energy is my improved and in general, I feel better. And the taste is very pleasant! My new provider wants me to continue doing what I am doing. This stuff is great.

Rated 5 out of 5 by from Best Energy My "Get up and go" got up and went.. so I've been using this terrific liquid with a dropper for a few years. One serving and 10 min. later I feel like getting on my feet & doing something. It really helps

Rated 4 out of 5 by from Great product The only bad thing about this product is the bulb at the top of the dropper is not big enough to suction 1 ML into the tube, which is the dose you are supposed to take. It only fills about 3/4 of the way full. I have to do 1/2 twice to get the full dose. Other than that, it is a great product.

Rated 5 out of 5 by from B 12 ENER B SHOT This product tastes great, is economically priced and I do notice an increase in alertness.

Rated 4 out of 5 by from Excellent Product Great taste. Excellent for taking B-12 supplement sub- lingual. No after taste easily absorbed. The best and only way anyone should take b-12 unless one needed injections. Just as effective SL in my opinion.

Rated 5 out of 5 by from More energy. I have been taking this for almost 2 years and I love it. Really works to give me more energy. I feel better when I take it. I use it in the morning and once more at lunch. I would recommend this product and I will continue to use it.

Rated 5 out of 5 by from Great morning pick me up!!! I take this every morning before my five mile jog. Within 15 minutes, I feel completely awake and alert. One serving has 83,000% of your daily B12, so it is more than adequate for anyone! It is a much better value than a 5 Hour Energy, since one bottle has 60 servings.

Rated 5 out of 5 by from Great tasting product I am usually not impressed with liquid vitamins, however this product is great tasting and fast acting, along with a B12 sublingual, it helps me to complete my task when ministering to our Church on Sunday mornings.

Rated 5 out of 5 by from More energy. I take a dropper full twice a day, and I find it gives me all the energy I need to make it. The taste is great, easy to swallow. I will order this again. I feel my health is better for it.

Rated 3 out of 5 by from Energeeee, I wish Going on two weeks now and nothing dramatic to say about this. I exercise very rigorously and would like a natural pick up, the type I get in pre-work out supplements. However, this is not it.

Rated 5 out of 5 by from Energy when I want energy. What I love about this product is it gives me energy when I want it. I take it before my workout and it kicks in fast. Once my workout is complete, I have no jitters and no crashing. Other energy drinks kept me up at night, this one lets me sleep like a baby.

Rated 3 out of 5 by from unexpected reaction Ordered the products before TG holiday. After the 1st try at recommended dosage, my heart raced terribly and my head was feeling spinning - I had to lie done ...the 2nd time, I reduced the dosage by less than half of the instructed amount, but my body felt the same reaction - I have liked Puritan's products so do my parents but this one is not feeling right - I am glad that I found out this bad reaction now. If I had taken this product during the regular work days, I might not be able to find a place to lie down in the office

Rated 1 out of 5 by from This product does nothing for me I was hoping this product would give me an energy boost without taking other products that contain ingredients that are harmful, but this product does not provide any type of energy boost at all. I am very disappointed with this product.
