Biotin Review - Does This Vitamin Really Work? Are user complaints and insufficient results deal breakers?

By Summer Banks on Aug 18, 2016
Biotin Review

Diet products either work or they don’t. Period. Let’s find out which on Biotin is. Our detailed review focused on the ingredients, side effects, customer service quality and scientific research. Moreover, we checked out countless user comments posted on the internet. Then, we summed up all of the facts to give you the information you need.

EDITOR'S TIP:

What is Biotin?

To start, Biotin is a vitamin that is found in foods such as carrots, almonds, halibut, milk and walnuts. It is also known as Vitamin B7 or H. It helps break down substances in the body such as carbohydrates, proteins and fats, which is likely the connection is has with weight-loss. While there is no set recommended amount for daily use, typically 10-100 micrograms per day is suggested.

Biotin has been available in supplement form for many years now. It’s easy to obtain online, as well as in local drugstores and supercenters. It is a natural vitamin that you can get from your daily diet and it may help with overall health, but read on…

User Complaints – “What’s Up?”

The first concern we have about Biotin ingredients is the fact that far too many dieters have complaints. “You’d think because this vitamin is commonly found in foods that there would be no problems,” says our Research Editor. “Surprisingly, we found more than we expected.”

According to one customer, “It caused these dry skin rashes all over my body, on my scalp, and my lips. My lips are so dry they’re bleeding.”

“After about 2 weeks of taking a full capsule, my skin started to break out, my breasts were extremely tender, and I noticed no change in my hair or nails,” said another user.

We found some positive customer comments. “I take 2 tabs daily and my nails are no longer soft and tender. My hair feels better as well,” said a user.

Insufficient Results – “Another Concern”

There is simply not enough evidence to link Biotin to weight-loss, something you can clearly see in numerous reviews.

In fact, one dieter commented, “Haven’t seen any effects yet in the past four weeks since I began using the vitamin.”

Another user stated, “Have not noticed any weight-loss, but a lot of acne breakouts.”

On the other hand, one customer stated, “I take 5000 mg Biotin daily on the advice of my dermatologist. It has helped a lot – it is subtle.”

“It takes several months to see results. Now my hair is coming in like crazy,” commented another.

Our research has revealed that if there is some particular part of a diet supplement or weight-loss program that is very problematic (insufficient evidence, too many user complaints, a fat price tag) the probability of long-term success is rather minimal. So, if Biotin does not work to help you lose more, this could be a serious problem.

The Science – “Valid?”

There have been some studies and research conducted with Biotin supplements. However, according to WebMD, this vitamin can help with conditions such as thinning hair and skin rashes. On the other hand, there is not sufficient evidence that it can help with weight-loss. For us at DietSpotlight, we need to see published science that supports the supplement and that’s not available. That’s an issue because there are clinically tested supplements out there we strong results and even stronger customer testimonials.

The Bottom Line – Does Biotin Work?

Should the dieter add this to their morning routine? While we appreciate that Biotin is an important vitamin that is healthy in small quantities, but we do not feel comfortable giving this one the green light because it is not associated with weight-loss. You should also note that too much of this vitamin can lead to side effects which can include skin irritation, acne breakouts and body pains. No one should ever settle for adverse reactions.

Those who need to slim down and trim off excess body fat, we encourage you to select a diet supplement that contains clinically tested key ingredients, is backed by excellent customer service and is supported by positive user reviews.

Among the best products we’ve seen in 2016 is one called Leptigen. It contains a proprietary blend of four ingredients, which have been shown in documented scientific testing to help accelerate fat loss and ignite metabolism. Also, we have not found many discussions of unpleasant side effects and customer feedback on the web shows people are seeing amazing results.

Also, it’s with great confidence that the makers of Leptigen are offering a Special Trial Offer, not something you find every day.

How Does Biotin Compare?

Previous Biotin Review (Updated September 20, 2014):

What You Should Know

It's important to understand that there are many ways to shed excess body fat and numerous key ingredients that can assist with this process. Take Biotin (used to be called Vitamin H) for instance. This is basically a "b-class" vitamin that can be found in a number of foods and supplements. The intestines produce Biotin in small amounts regularly. This substance has been linked to weight loss because it aids the metabolism of carbohydrates, protein, and fats. Common foods that contain Biotin are poultry, rice, vegetables, beef, spinach, oatmeal, nuts, and egg yolks.

Not only has Biotin been linked to weight reduction, but it has also been associated with hair maintenance, bone strength, and the health of finger/toe nails. This means that brittle nails and hair loss can be attributed to a lack of Biotin in ones diet. In regards to weight loss this vitamin is claimed to aid the body with processing food and utilizing energy more effectively. This is why some people believe that Biotin boosts energy levels and leads to a slimmer figure. Some supplement formulas that offer Biotin are Country Life Biotin capsules, Natrol Biotin tablets, Twinlab Biotin capsules, and AST Multi Pro 32X http://www.dietspotlight.com/biotin-review/caplets.

Product Features

Biotin aims to increase energy levels by assisting with food digestion. Those that lack this substance in their diet can experience afflictions such as dry skin, hair loss, mental depression, nausea, fatigue, and brittle nails.

Advantages

  • Biotin is good for the human body and may assist people with having healthier skin, nails, and hair.
  • Biotin is a natural substance.

Disadvantages

  • There are no documented clinical studies which heavily support Biotin as a weight reduction ingredient.
  • Biotin does not aim to suppress the user's appetite.

Conclusion

Studies have shown that this substance can benefit the user's hair, skin, nails, and overall health. In efforts to improve total body appearance, many users, when starting a new weight-loss program, also begin a skin-care routine. Products like Neutrogena Rapid Wrinkle Repair and Ponds Age Miracle claim to help with the signs aging. However, when it comes to issues like real weight-loss, whether or not Biotin supplements will assist dieters with shedding excess body fat is not certain. It's probably a good plan to investigate a number of products before giving Biotin supplements a shot. After all, there are a number of others that are better supported by studies.

    I have been taken Biotin for almost two months now. At first I started to break out a little with pimples. Now its all gone and I have noticed my hair is growing, my appetite is less. I always had nice nails and skin. However, I drink lots of water like 5 or 6 bottles of water a day. This is the key. Lots of water. Yes your peeing a lot but your hair is growing, less appetite and your on the road to beautiful hair now. This pill has worked amazing for me. Good luck peeps! 🙂

    From what we’ve gathered, Kimberly, biotin isn’t designed specifically for weight gain. We recommend looking around our site for suitable alternatives.

    I’ve been taking the biotin 5000 mcg for 2 weeks. Haven’t noticed much yet except this one problem, dry patch on my face disappeared. Nails are still not stronger. I have to keep them short so can’t comment on the growing of them. I really hope it would help my hair which is so dry and dull despite everything I do with it: conditioning, deep conditioning, co washing, masks, oils etc.. So far nothings happened with that either. By the way, this stuff will make you break out if you aren’t drinking enough water.

    I took Biotin for 6 months – 7500 mcg – and I feel it made a noticable difference in my nails (no peeling and splitting)and my fine thin hair felt thicker with more volume. I ran out for 2 months but am back on it, I might increase to 10,000 mcg a day as I saw no ill effects.

    I am now taking biotin as a hair regrowth product. I have taken it at least 1 week today and I do see a in my appetite, my energy level and to me, my skin looks a lot better. Right now I would give it 5 stars. My hair feels softer and that leads me to believe it is starting to work. Will get back with an update as the time goes on. Most importantly it is easy to take. I was really excited to know it assists with diebetics as that is running rapid in my family although I do not have it.

    Its because of the increase in metabolism. Increase in urination keeps body active all the time. Cells never rest 🙂

    Biotin is a must-have. The ingredient Biotin, or vitamin B7, is crucial for the production of keratin, the key structural component of hair, nails, and skin. Daily doses as high as 60 mg a day can be taken for long periods, as there have not been any reports of biotin toxicity.

    I also make sure to use a shampoo with a high biotin and vitamin content – for this I recommend the Shielo Volume Shampoo. The Shielo shampoo, combined with biotin supplements, will give you everything you need. I had success using both together.

    I dont know if it actually works for weight loss but what i do know is that it does work for hair. I bought a bottel containing 100 tablets with 1000mcg at target for $3.00 and in 2 weeks my hair has grown 1 1/2 inches, and i have like 1 1/2 inch of baby hair growing all over my head wich is exiting for someone with thin hair that seems like it never grows. I do take 6 tablets trough out the day 2 in the morning after lunch and 2 before dinner wich equals to 6000mcg. I think its fine considering that there are tablets that contain 7500mcg each.

    Thats so true! When I started taking Biotin 6 months ago, I broke out here and there but nothing horrible. Eventually the breakouts stopped. My nails and hair have grown alot. My hair sheds less, and my nails never chip or break anymore.
    Also, I noticed my appetite is nonexistent. This is good and bad. I have lost weight but when it comes time for me to eat my appetite is nowhere to be found. I eat small meals- as I seem to get full very quickly. Food isn’t as enjoyable as before and it takes forever to finish a meal.

    I just purchased biotin today, and plan to start it tomorrow so I thought I would do a quick review on it to see if it really works. First off let me say that in these reviews I have seen where some say that the supplement is causing breakouts of tiny pimples all over the face.. As a cosmeologist I know that when starting any type of new skin care or supplement helping overall skin health, your skin is GOING to get worse before it gets better simply because that is your body working to push all of the bad stuff out of your pores. Once all of the dirt and oil is out that is when your skin health will improve. I have seen where people say they stop taking biotin to see if it will help the breakouts, NO! You are stopping the process!’ continue taking the supplement, tough it out for a few more weeks and see what happens then. I cam pretty much guarantee your skin will look better, and healthier than ever. I mean think about it.. Your nails grow.. And get rid of the old brittle nails, your hair grows out so you can cut the dead stuff off, your skin is pushing all the grime out to it can become more healthy 🙂
