What is a B12 Shot?

Firstly, these drops are a highly concentrated vitamin supplement that’s supposed to boost energy and, potentially, support weight-loss. B12 Shot ingredients include large amounts of Vitamin B12. While the product websites do not cite the full list, they do mention several others, including Water, Citric Acid, and Potassium Sorbate.

There are multiple manufacturers. Some specialize in the oral supplement and others in B12 injections. If taken by mouth, you do not need a prescription. We like that these are all natural and you can find them anywhere, but read on…

Taste – “Yuck!”

Our first concern with vitamin B12 Shots is the poor taste. “If something doesn’t have a good flavor, people aren’t going to use it. Some complain it is so bad they want to vomit,” said our Research Editor.

”I dislike the taste. It’s the color and consistency of Nyquil cough syrup that I took as a child. Yuck. My children tried tasting a drop and hated it,” said one user.

”It tastes pretty terrible. It is very oranges so be careful when dosing so you don’t get it places it could stain,” shares a dieter.

Others love the taste.

“This particular one has no scent but has a citrus, almost tart taste. I was a little worried that it would have a strong taste and that I wouldn’t be able to tolerate it. However, it’s not bad at all,” was an experience.

“The taste is super sweet/sickly sweet but not disgusting that will make me vomit,” said another.

B12 Shot Inaccurate Dosing – “Potential Problem?”

Several customers complained the dropper didn’t allow them to get the right dose.

”I tried many times to get 1 ml into the dropper, but the most I could get is closer to 3/4 ml, often times it ended up being 1/2 ml,” said a customer.

”The dropper does not provide equal dosing,” explained another.

Others were able to make it work just fine and noticed changes as a result.

“I recommend this to anyone with low b12 or if you’re tired all the time. Worth a shot, it’s helped me,” said a reviewer.

“I have been taking your B12 liquid supplement for only a few days, but I’m already seeing results. I am getting the best restful sleep I have had in years. My energy and focus are improving also,” as another customer put it.

Our years of experience have taught us that it only takes a simple thing, like poor flavor, to send customers running to the competition for a better solution. In this case, if the taste of vitamin B12 shots is terrible, dieters won’t take it more than once.

The Science – “B12 Helps, But…”

Vitamin B12 is connected with energy production, science proves that without a doubt. What is missing is a connection with taking extra and losing weight. There’s just no reason to believe this will happen, especially since the body pushes out any extra as it is not stored.

At DietSpotlight, we want to see science connected to weight-loss before we can recommend any product.

What Users Are Saying

"”I am surprised how well this works. I have several auto immune disease’s. All of them bring extreme fatigue. The past 4 months the fatigue has been worse than usual. I tried a B12 pill & didn’t have any change. I’ve only been using this for a few days & feel a big difference.”"

"”Take it daily, taste okay, but after a month, don’t really notice an improvement.”"

"”The liquid vitamins made me immediately vomit. I tried in a few different drinks, but same result.”"

The Bottom Line – Does B12 Shot Work?

What’s the real deal with B12 Shot? We like that it’s natural and the availability is amazing, as is the price, but we are skeptical about suggesting it for weight-loss. The science just isn’t there and no matter the cost, if it doesn’t work it’s a waste of money.

If you want to shed those extra pounds, why not try a supplement with clinically tested ingredients shown to you reach your weight-loss goals?

Among the best products we’ve seen this year is Dietspotlight Burn. It’s made with a unique blend of four ingredients, all of which have been shown in clinical testing to help support metabolism and fat loss. Our review of customer feedback showed no negative comments or mentions of harmful side effects, so we know users are getting solid results.

Also, readers can get a Special Trial Offer directly from the manufacturer, and this the kind of thing we love to see.

Previous B12 Shot Review (Updated August 12, 2013):

What You Should Know About the B12 Shot

B12 Shot is a liquid dieting supplement that claims to cause rapid weight loss. The product contains large quantities of Vitamin B12, along with other nutrients. The product claims to decrease water retention, detoxify the body, boost the metabolism, and stimulate the thyroid gland. The manufacturers claim that for the product's full potential to be reached, a heavy dairy diet is needed. Dairy products contain large amounts of vitamins, primarily Vitamin B12, and the manufacturers claim this will boost the affects of B12 Shot.

List of Ingredients

B12 Shot contains large amounts of Vitamin B12. While the product's website does not cite the full ingredients list, they do mention several other ingredients. Water, Citric Acid, and Potassium Sorbate are all mentioned ingredients.

Product Features

The number one feature of the product is that, the manufacturers claim, you can take B12 Shot and receive an increase in energy without the crash later on. The manufacturers claim this is due to the fortifying vitamins and other natural ingredients in B12 Shot. The manufactures of B12 Shot claim that the effect of their product is the same as receiving injections of Vitamin B12, which many people receive because of its healthy effect on the body. They claim their product has 2,000 mcg of Vitamin B12, the same as one injection. They offer the same effect, without the hassle and pain of a needle. B12 Shot also claims to aid in rapid weight loss, if taken with proper exercise.

Advantages of a B12 Shot

  • B12 Shot is a healthy and nutritious product that contains large quantities of vitamins and minerals.
  • The manufacturers claim that if taken regularly, B12 Shot cleanses the digestive system, promotes better overall body health, and supports a healthy heart and central nervous system.

Disadvantages of a B12 Shot

  • The manufacturers of B12 Shot are vague about the product's contents. The website fails to clearly outline the full list of ingredients, as well as providing a picture of the products ingredients label.
  • The manufacturers fail to specify if the product has successfully gone through clinical tests, nor does the FDA give their consent of the product.
  • The product's website fails to provide before and after pictures. They also fail to provide customer bios about the product.
  • B12 Shot seems relatively overpriced. They also fail to give any type of promotion or discount for purchasing the product.
  • The manufacturers fail to incorporate any type of dieting or exercise plan to be used with their product.

Conclusion

While B12 Shot is a healthy and nutritious product, that the manufacturers claim will boost the body's overall health and performance, these claims seem to be somewhat exaggerated. While B12 Shot has been on the market for a long period of time, there just does not seem to be enough information, either presented by their own website or other affiliated websites, that back up the claims presented by the manufacturers of B12 Shot.
