Biotin and Weigh Gain

The body turns excess calories into fat. The first key step in the process uses an enzyme that is dependent on biotin. The enzyme is called acetyl-coA carboxylase, or ACC.

Decreased ACC enzyme activity may result in reduced synthesis of fat for storage as triglyceride and greater use of fat as an energy source, that is according to the results of a mouse study published in 2007 in Proceedings of the National Academy of Sciences.

Overweight and obesity are associated with elevated triglycerides — fat — and LDL — the “bad cholesterol” both of which are risk factors for heart disease. This makes biotin a factor leading to weight gain

What it all means is that insufficient biotin within your body may lead to slow or weak metabolism which in turn can result to a number health issues including weight gain. However, this appears a very indirect way of gaining weight. Other signs of a slack metabolism include;

  • Digestive problems
  • Poor moods
  • Possible development of diabetes
  • Changes in appetite

According to experts, most vitamin deficiencies (including Vitamin D & B-12) actually manifest as weight gain. For those who want to gain weight, this unfortunately isn’t the recommended way to gain weight. You need the vitamins for your body to stay health and function well. Biotin isn’t specifically designed for weight gain.

One aspect that seems common amongst a couple of the reviewers is that biotin increases your appetite which you will be eating more and more. The link between biotin and appetite is not clear. In fact, some claim that biotin actually curbs hunger.

Here are some of the user reviews

“I have always had a high metabolism and I’m very active, so I don’t really worry about weight gain. I eat very healthy and work out regularly. I’m 5’5 and normally weight anywhere from 116-118. I’ve been taking biotin 5,000mcg twice a day for the past 7 months and have gained weight!! I have gained about 12 pounds. I couldn’t figure out why I had gained the weight. So I started exercising even more and couldn’t lose the weight. Even though I love what biotin has done for my hair and skin, it’s just not worth the weight gain. This makes so much sense. I am going to stop taking it from now on. Thanks for sharing your experiences, ladies! This has really helped me.”,

“… I am very active as well and eat healthy like 95% of the time and I have definitely noticed weight gain. IT MAKES YOU CONSTANTLY HUNGRY! It’s uncontrollable! Also I use an acne treatment that is VERY effective and since I started taking Biotin my face has gotten considerably worse. So yep. You either get good hair and nails or you get acne and weight gain. Your choice.”

Ladies all of your comments have been so helpful… I’m 46 and have had weight loss surgery I’ve lost 152lbs for almost 4yrs now. I recently about 3 weeks ago started taking 1000mcg Biotin as advised by my cousin to thicken my hair. And strangely have been eating even more than I can take in. I’m constantly hungry and I have gained 6lbs added on to the 6 I gained during the holidays lol. I started to panic that my surgical procedure was starting to fail.
Your comments have truly helped me. Now I have to get this 12lbs off of me for good. Good luck to you all

WebMD Review

On WebMD answers, Maryann Tomovich Jacobsen, a registered dietitian with 15 years of experience in the nutrition field, says that there is no research that biotin causes weight gain.  Weight gain is typically caused by a calorie imbalance and certain medications, but not vitamins. If you want to control your weight, a balanced diet is more effective than supplements
