The product is found useful for the following medical conditions

We explored a unique case involving a girl diagnosed with biotinidase deficiency, a rare inherited metabolic condition that can lead to notable skin and hair issues. The report highlighted her struggles with intractable dermatitis, yellow hair, and alopecia—symptoms that pointed to the underlying deficiency.

Biotin, a vital nutrient, was administered at a dose of 20 mg per day as a replacement therapy. Within one month, we observed a substantial improvement in her dermatitis, and by the three-month mark, her hair color had returned to near normal. The significant change in her condition illustrates how effective biotin can be for individuals suffering from both biotinidase deficiency and associated eczema-like symptoms.

This case serves as a reminder for healthcare providers, especially dermatologists, to consider biotinidase deficiency as a potential factor when treating similar conditions in children. By recognizing the importance of biotin, we can help improve health outcomes for those experiencing dermatological challenges tied to this rare disorder.

Hypothyroidism details

SCIENTIFIC SCORE

Questionable

Based on 2 Researches

Low-dose biotin effects minimal

Angelopoulos N, Paparodis RD, Androulakis I, Anagnostis P, Boniakos A, et al. The clinical significance of low dose biotin supplements (<300μg/day) in the treatment of patients with hypothyroidism: crucial or overestimated?. Thyroid Res. 2023;16:18. doi:10.1186/s13044-023-00162-8

We set out to investigate how low-dose biotin supplements, specifically those containing less than 300μg per day, might affect thyroid hormone levels in patients with hypothyroidism. Our approach included a detailed evaluation of 57 patients who were receiving thyroxine and also taking biotin supplements for a period ranging from 10 to 60 days.

Throughout the study, we measured the levels of thyroid-stimulating hormone (TSH) and free T4 (FT4) while the patients were on biotin and again 10 days after they stopped taking the supplement. As a control, we compared these findings to those of 31 age-matched individuals who were also being treated for hypothyroidism but were not using biotin.

Our analysis suggests that any changes observed in thyroid hormone profiles due to low-dose biotin supplementation are not clinically significant. In most cases, these changes do not warrant any adjustments to the patient's thyroid medication.

Overall, while our findings contribute to understanding the relationship between biotin and thyroid hormone levels, it appears that low-dose biotin may not play a crucial role in the treatment of hypothyroidism. Larger, more comprehensive studies would be beneficial to explore this phenomenon further.

Stopped hair loss

Most Useful Review

After three months of taking this supplement, my hair loss has stopped, and my nails are stronger. I have chemical sensitivity and hypothyroidism, both of which contribute to hair loss. This supplement has a higher content of ingredients compared to Japanese biotin, and it has helped my hair and skin feel better. I even take more on days with strong chemicals due to its detoxifying properties.

Irritable Bowel Syndrome details

Improved bowel health

Most Useful Review

My bowel health has improved significantly.

Bruise details

Enhanced eyelash growth

Most Useful Review

It was effective. There was a bruise on his forehead, and his eyebrows were plentiful, but they became rich. My eyelashes have grown longer.

Celiac details

I’ve been thoroughly impressed with Natrol Beauty Biotin, which offers 10,000 mcg per serving. The potency significantly supports healthy hair, skin, and nails. Since I started taking it, I’ve noticed visible changes in my hair's strength and shine, as well as enhanced skin texture. I'm pleased that it is free from gluten, dairy, and artificial colours, making it safe for those with specific dietary needs. The quality of the ingredients is commendable, and the formula absorbs well, amplifying its effectiveness. The tablets are also small and easy to swallow, with no unpleasant taste. Overall, this product has greatly improved my beauty regimen, and I highly recommend it to anyone looking to elevate their skincare and haircare routine.

Common Cold details

Hair regrowth observed

Most Useful Review

Delight! After falling ill with the common cold, my hair suffered severe loss. Within a month of taking biotin, the loss notably reduced. I observed regrowth, particularly at the roots, and shorter hairs at my forehead are also coming back nicely. One tablet a day is convenient, and the small size makes it easy to swallow. I hope my review assists you!

Depression details

I've taken this vitamin for several months now, and it has been excellent. I take it daily to maintain my health, and I've seen improvements not only in my immunity but also in my mood, which is fantastic given my battle with depression.

Multiple Sclerosis details

Effective for patients

Most Useful Review

I love this Biotin as it aids energy production and the activity of enzymes crucial for breaking down proteins, fats, and carbohydrates. It promotes hair growth, reduces hair loss, and strengthens nails. Studies show an obvious improvement in nail durability. Additionally, Biotin can enhance skin condition. Importantly, it's being used in treating multiple sclerosis, with studies showing improvements in over 90% of cases using increased doses.

Rosacea details

Very good! My rosacea is improving since I started taking the biotin. I'm grateful and pleased with the results.

Stroke details

Effective for recovery

Most Useful Review

This product really helps with hair loss! My hair fell out terribly after childbirth; even a gentle stroke would leave me with clumps of hair in my hands. On my doctor's advice, I completed three courses of biotin. Now, my hair is thick, and it no longer falls out excessively, even when I wash it.

Back Pain details

This product effectively saved me from postpartum hair loss! Three months after giving birth, I experienced significant hair loss, but after taking this supplement daily, I noticed my hair started to grow back, and daily shedding has nearly stopped. My hair is returning quickly, and I believe it has shortened the duration of my hair loss. Highly recommended for mothers!

Blurred Vision details

Effective for blurred vision

Most Useful Review

A flat circle. The small, drinkable tablet is truly popular for a reason! Its shape is very easy to drink. The bottle’s compact size is convenient, and as 10,000 mg is excessive at once, I split it and take it twice daily, morning and night. I wanted to address both my blurred vision and flying mosquitoes simultaneously, so I tried "biotin plus" with lutein. The results were fantastic. However, the tablet is hard and slender, making it challenging to swallow. I’m used to American supplements that usually go down easily, yet this one seems to get stuck. Increasing moisture helps a bit, but it still often remains lodged in my throat. Although I attempted to split it, I still struggle with taking it.

Cardiovascular Disease details

Seborrheic dermatitis relief

Most Useful Review

I've had seborrheic dermatitis on my scalp for years, but after a month of taking biotin and krill oil, the itching has reduced dramatically. I intend to continue this regimen as I’ve experienced such positive results. I believe in the quality of iHerb's supplements and feel reassured using them.

Floaters details

I have managed to stop the hair loss process! The tablets are small and easy to swallow. After taking these vitamins for a month, I've noticed that my hair loss has decreased by 2 to 3 times. Although I still see some hair in the drain and a bit more when using the hair dryer, it's nothing compared to before! I believe my hair is slightly thicker, but I am certain that I have finally halted the hair loss!

Menopause details

I've noticed my hair is growing, and my nails grow faster now. I am in my forties and experiencing mild menopause. My lifestyle has been hectic, and after a month of taking this supplement, the speed of my nail growth accelerated while hair issues improved overall. I feel my hair is growing thicker.

Allergies details

Based on 3 Researches

Biotin's impact on allergies explored

Kuroishi T. Regulation of immunological and inflammatory functions by biotin. Can J Physiol Pharmacol. 2015;93:1091. doi:10.1139/cjpp-2014-0460

We investigated the effects of biotin on immune responses and inflammatory conditions. Biotin, a necessary vitamin, plays a role in various metabolic pathways related to inflammation. While previous studies have suggested that biotin deficiency can lead to skin inflammation and immune issues, our findings highlight the potential of biotin supplementation in addressing metal allergies in animal models. However, significant improvements in allergy symptoms were not conclusively shown. Thus, while biotin may be beneficial, more research is needed to fully understand its impact on allergies.

9.5

Inhibits itch production

Most Useful Review

Atopy and allergies! High concentrations of biotin are beneficial. After 20 years on antihistamines, I sought to stop them and began taking biotin. I found that biotin aids in eliminating essential amino acids like histidine, which helps metabolise histamine, thereby alleviating the itch.

Anemia details

Great! I take it in the morning on an empty stomach one hour before eating or in the evening two hours after my last meal. My nails are stronger, and I have noticed improvement in hair growth and density after taking an iron supplement. My hair loss has significantly decreased. If you're suffering from anaemia, biotin alone won't solve hair issues; it's best to take an iron supplement too. Thumbs up!

Blood Clot details

Increased hair growth

Most Useful Review

Since taking this biotin supplement, my hair growth has been remarkable, and my nails are growing much faster. Despite a busy life and only averaging five hours of sleep, I've felt improvements in my overall health. I've noticed less unwanted hair growth, and I'm experiencing noticeable changes in my hair and nails in just a month.

Chronic Cough details

Very satisfied! As I often touch water at work, I suffered from chronic hand roughness and weak nails, often resulting in doubled nails and breakage. After beginning biotin, I noticed improvement in my hands' textures within a week and a significant decrease in nail issues after three weeks. My nails are now much stronger than before!

Cai X, Zhang M, Zou J, Wang L, Zhan Y, et al. A novel self-assembling peptide nanofiber hydrogel with glucagon-like peptide-1 functionality enhances islet survival to improve islet transplantation outcome in diabetes treatment. J Nanobiotechnology. 2024;22:792. doi:10.1186/s12951-024-03072-5

We explored a cutting-edge peptide hydrogel designed to improve islet transplantation outcomes for diabetes. By integrating glucagon-like peptide-1 (GLP-1) into a self-assembling nanofiber structure, we aimed to address the common issues of islet graft survival and function.

In our tests, this innovative hydrogel notably increased islet function and longevity, reducing inflammation and enhancing metabolic control in a mouse model. The findings show promise for localized delivery methods and suggest a potential breakthrough in diabetes treatment through improved graft efficacy.

9.5

Promotes hair growth

Most Useful Review

My mother has type 2 diabetes and since taking biotin, her hair loss has decreased significantly. After starting biotin alongside her ketogenic diet, she noticed new hair growth. She plans to continue purchasing this product as it has been effective for her hair and glucose levels.

Osteoporosis details

With a deficiency of vitamin D3 in women, the risk of various genitourinary diseases increases. During pregnancy, vitamin D3 aids calcium-phosphorus metabolism for a healthy gestation. Following menopause, the risk of osteoporosis significantly rises due to low estrogen. I took biotin for my hair, nails, and skin, and after one jar, I noticed a marked improvement.

Psoriasis details

I have suffered from psoriasis vulgaris and have been taking biotin for some time. With three tablets daily, I’ve healed from within and feel that my hair and nails grow rapidly.

Adenoiditis details

Hair density restored

Most Useful Review

I would recommend this product to anyone! While taking antibiotics, my hair was coming out in handfuls when washing, and my throat felt very sore. After five days, hair loss decreased by 70%, returning to a normal shedding rate of 7-9 hairs per wash after two weeks. I take half a tablet once daily, which lasts me six months! I now hope to restore my hair density more quickly with biotin. I advise everyone to try it.

High Cholesterol details

Chromium and biotin affect diabetes

Albarracin C, Fuqua B, Geohas J, Juturu V, Finch MR, et al. Combination of chromium and biotin improves coronary risk factors in hypercholesterolemic type 2 diabetes mellitus: a placebo-controlled, double-blind randomized clinical trial. J Cardiometab Syndr. 2007;2:91.

We investigated the effects of a combination of chromium and biotin on cholesterol levels in people with type 2 diabetes. In a randomized, double-blind trial with 348 participants, those taking the supplement showed improvements in blood sugar levels and cholesterol levels compared to the placebo group.

However, while the chromium and biotin combination did yield positive results for cholesterol in some participants, overall, we found no significant changes in lipid levels for all participants. This suggests that while chromium and biotin may help with metabolic factors, their direct impact on cholesterol may be limited.

9.5

Successful hair regrowth

Most Useful Review

Miracle biotin! I struggled with hair loss for a long time and tried everything, but only biotin worked. I developed a routine of taking half a tablet, which successfully stopped my hair loss and significantly increased hair growth. I am thrilled with the results!

Hives details

The saviour for unexplained hives! Although I used to ignore my hives, one day stress triggered a severe outbreak. After hearing about biotin's benefits, I decided to try NATOROL's biotin and Acidophilus. Remarkably, the hives subsided immediately! I'm so impressed and grateful. The value for money is exceptional, making it the most effective supplement I've purchased. I intend to repurchase this product.

Abscess details

Housewife's eczema, which I suffered from, was painful and spread upon scratching. Despite visiting several dermatologists, I only saw minimal improvement with steroid ointments. After researching online, I tried biotin. After a while, my condition returned to normal. I continue to take biotin regularly.

Migraine details

Regular intake of two capsules has significantly normalised my sleep and improved my migraines. When symptoms arise, I take the pills and extra magnesium, which usually alleviates the migraine within a couple of hours. The frequency of my migraines has decreased, and magnesium helps alleviate PMS symptoms. Additionally, I’ve noticed less chronic pain in my nasopharynx. I haven't experienced any side effects like allergies or stomach issues. The quality is excellent, with natural ingredients that positively affect health.

Pelvic Pain details

The results have been fantastic! After a month of biotin, I noticed less hair loss and new fluffy hair sprouting. However, I must caution those with gastritis; I experienced severe stomach pain on it and had to stop. For those without such issues, I recommend trying it for noticeable effects!

Reflux details

Excellent! Biotin in this dosage helps me with bile reflux. I take it in the morning with breakfast. Good therapeutic dosage, and the package lasts a long time.

Yeast Infection details

This biotin product has enhanced my hair health, significantly reducing hair fall. I’ve also noticed an improvement in my blood sugar management, and it has made controlling my yeast infection much easier. Overall, I feel this vitamin contributes to my wellbeing.

Leg Cramps details

No dermatitis experienced

Most Useful Review

For the first time, I did not experience dermatitis during pollen season this year. Since childhood, I have suffered from itchy legs and facial discomfort from February to May, but I resisted medication for hay fever dermatitis. My scalp has been sensitive and itchy, despite using an amino acid shampoo. I took biotin, and this year my face remained clear during pollen season, allowing me to feel comfortable. Additionally, my skin stayed moisturised, and my scalp gradually improved, though it's still a work in progress.

Swollen Lymph Nodes details

Inflammation reduction

Most Useful Review

I take biotin with Acidophilus three times a day to alleviate atopic dermatitis symptoms. I've noticed that it effectively suppresses swelling inflammation and has improved the smoothness of my skin, even in areas without atopic symptoms.

Nausea details

This supplement, prescribed by my doctor, has been a useful aid for hair growth. By the end of the month, I noticed less hair falling out and improved hair quality.

Moderate benefits, high testing interference

Espiritu AI, Remalante-Rayco PPM. High-dose biotin for multiple sclerosis: A systematic review and meta-analyses of randomized controlled trials. Mult Scler Relat Disord. 2021;55:103159. doi:10.1016/j.msard.2021.103159

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.

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.

Bone Pain details

I gave birth at 35 and developed bone pain shortly after. This led to stress and hair loss. After using biotin shampoo and supplements from iHerb, the hair loss decreased significantly, which has positively impacted my mental state.

Sleep Apnea details

This little tablet has become my best friend! I struggle to switch off at bedtime, but taking one tablet 20 minutes before sleep has worked wonders. I enjoy vivid dreams and sleep soundly through the night without waking up to pee. Though I wake slightly tired, it’s manageable with coffee. Highly recommend for anyone struggling with sleep.

Urinary Tract Infection details

Biotin is an excellent remedy for digestive issues. I experienced no heaviness after meals, and my gastrointestinal tract functions much better.

Heartburn details

Consistent heartburn issue

Most Useful Review

It’s acceptable, but I experience heartburn often. I take it after dinner, and despite the extra strength dosage, I frequently feel heartburn afterwards.

Obesity details

It's wonderful! My hair has improved significantly with this, and it has not caused any obesity.

Insomnia details

Thanks to this product, my insomnia has significantly improved, allowing me to sleep well.

Headache details

I can now sleep well after previously using commercial sleep inducers which caused headaches and fatigue. Melatonin has allowed me to sleep naturally. If you experience similar issues, I recommend melatonin but advise using it according to your condition.

We examined the impact of Baitouweng Decoction, a traditional Chinese herbal remedy, on diarrhea caused by dampness-heat conditions. By using Wistar rats, we created various test groups to observe its effectiveness compared to a control group.

Our findings showed that Baitouweng Decoction significantly improves diarrhea symptoms, suggesting it works by reducing inflammation and preventing cell death. The study also highlighted key metabolic compounds like biotin that play a role in its healing effects.

Effective but diarrhoea

Most Useful Review

The quality is good and the quantity large. I noticed a 90% reduction in fallout, though the first day caused me diarrhea, which then normalised.
