Natrol Biotin

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.

Premenstrual Syndrome 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.

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.

Anxiety details

These vitamins truly work! My anxiety has diminished, and I’m sleeping better. However, taking four capsules feels excessive. I recommend dividing the dose into two in the morning and two before bed. They are expensive, but effective for stress relief without causing drowsiness!

Hypothyroidism details

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

Questionable

Based on 2 Researches

Low-dose biotin effects minimal

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.

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! 👍

Biotin treatment for eczema effectiveness

Moderately Effective

Based on 5 Researches

Yang Y, Yang JY, Chen XJ. Biotinidase deficiency characterized by skin and hair findings. Clin Dermatol. 2020;38:477. doi:10.1016/j.clindermatol.2020.03.004

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.

Allergies details

Biotin's impact on allergies explored

Moderately Effective

Based on 3 Researches

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.

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.

Leg Cramps details

No dermatitis experienced

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.

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.
