Moderate benefits, high testing interference
We evaluated the effectiveness of high-dose biotin in treating multiple sclerosis through a systematic review of randomized controlled trials.

Our findings suggest that patients could see some benefit from using high-dose biotin over a period of 12 to 15 months.

However, it's important to note that this potential upside comes with a notable downside: an increased likelihood of affecting laboratory test results.

Overall, the evidence remains moderately certain, indicating a cautious approach is necessary for those considering biotin treatment for multiple sclerosis.

Biotin improves disability in PMS
We evaluated the effectiveness of high-dose pharmaceutical-grade biotin (MD1003) in enhancing treatment responses for patients with progressive multiple sclerosis (PMS). Over one year, we monitored 48 newly treated patients, using clinical assessments and brain volume metrics.

Encouragingly, 27% of patients experienced a notable reduction in disability scores. Additionally, improvements in brain and cervical spinal cord volume were observed in several patients. Yet, those with higher levels of neurofilament light chains or older age at MS onset appeared to have less positive responses to treatment.

Dexamethasone delivery variations studied
We explored how different linkers and lengths in biotin-dexamethasone conjugates affect drug delivery to the liver, particularly in autoimmune hepatitis. Through in vitro and in vivo studies, we noted that certain combinations enhance drug stability and uptake in liver cells.

Our findings suggest that tweaking the construction of these nanoparticles can meaningfully influence how effectively the drug works in the body. This could lead to better steroid formulations tailored for various medical needs.

Hair growth

The results have been impressive! I ordered this as my hair was falling out significantly. After three months, I barely noticed any loss, and others remarked on my hair's thickness. My nails have also strengthened considerably, and there were no side effects. I highly recommend it.

Nail growth

I received this product in a week and am beginning my journey with it. A friend with an autoimmune disorder saw excellent eyelash growth, so I’m excited about my own results as well. My nails are already growing faster, and I can't wait to see more improvements!

Biotin shows promise in BTD
We explored the unusual manifestations of biotinidase deficiency (BTD), showcasing three cases initially diagnosed as neuromyelitis optica spectrum disorder (NMOSD).

These patients exhibited severe symptoms such as quadriplegia and vision loss. Although some responded to immune therapy initially, they relapsed, while one did not improve at all.

Following further testing, it became clear that BTD was the true culprit. Remarkably, two patients experienced significant recovery after starting biotin supplementation, highlighting the potential of biotin in treating this deficiency.

Biotin and thiamine improve symptoms
We observed a fascinating case of a four-year-old girl diagnosed with Thiamine Metabolism Dysfunction Syndrome 5 and acute disseminated encephalomyelitis, who exhibited marked improvement after treatment with biotin and thiamine. Initially presenting with fever and agitation post-vaccination, genetic tests later revealed a pathogenic variant in the TPK1 gene. The girl's clinical status improved significantly, with resolution of autism spectrum disorder symptoms, supporting the role of early intervention. This case strengthens the evidence for biotin and thiamine in treating metabolic deficiencies related to TPK1.

We explored two intriguing cases of biotinidase deficiency, a rare genetic disorder that can mimic conditions like Neuromyelitis Optica Spectrum Disorder. Initially, both patients received treatments for immune-mediated disorders, but when their symptoms worsened, further testing revealed biotinidase deficiency.

Remarkably, after starting biotin supplementation, both children showed significant improvement. This highlights the importance of recognizing atypical neurological signs, as early diagnosis and treatment of biotinidase deficiency can lead to effective intervention.

Biotin shows potential in neuropathies
We set out to examine the effects of high-dose pharmaceutical-grade biotin on patients with different types of demyelinating neuropathies.

In a pilot study involving 15 participants, we aimed to see if this treatment could improve various nerve function measures.

While the main goal of achieving a 10% improvement in specific nerve conduction measurements wasn’t reached, many participants showed better sensory and motor abilities.

Overall, these findings suggest that high-dose biotin might help in some ways, and the treatment was well-tolerated by participants.

Stopped hair loss

I took this when my hair was growing poorly and falling out. I started with one a day for two months, then half for another two months. After a month, the hair loss stopped, and new growth began. I continue to take it weekly to maintain the effect. This biotin is excellent; it helped greatly against hair loss, and the price is fantastic!

Improved hair thickness
2 people found this helpful
I've ordered two more bottles due to a 25% discount. The Natrol Biotin is of excellent quality for treating hair thinning and loss. My husband saw bald patches after his vaccination but, after over a month of taking biotin with a growth tonic, those areas are now covered in new hair. I also noticed improved skin texture and stronger nails. I decided to try it myself, as the tablets are small and easy to swallow.

After giving birth, I experienced significant hair shedding due to an autoimmune disorder. Biotin reduced the loss after half a month. With added omega-3, the results are fantastic—my hair no longer falls out and my eyelashes have grown longer!

In spring 2020, I faced major hair loss due to stress. When various treatments failed, I tried biotin and vitamin D3. After a month, my hair fall decreased significantly, and I've observed notable length growth. This dietary supplement has been immensely helpful, prompting me to plan a reorder.

Skin condition improved

I ordered biotin for my son's seborrhoeic dermatitis. Initially, dermatology suggested steroid treatments. After taking it with vitamin C, I saw marked improvement; redness subsided and my skin changed positively. I started taking it too and noticed my nails were healthier.
