The product is found useful for the following medical conditions

We encountered a case of a woman suffering from short bowel syndrome, who faced significant hair loss due to biotin deficiency while on home parenteral nutrition. After starting oral biotin supplementation of 10 mg/day for three weeks, we observed that her serum biotin levels increased, leading to noticeable new hair growth and resolution of other symptoms. Further intravenous biotin treatment maintained her on multivitamins that include biotin, preventing any future deficiency symptoms. This case highlights the importance of addressing biotin levels for hair health and overall well-being.

Adrenal Gland Disorder details

Biotin is essential! It must be included in the diet, as it aids in the conversion of proteins, fats, and carbohydrates into energy. A lack of energy affects physical activity and emotional well-being. Biotin improves hair health, and insufficient intake can lead to hair loss, brittle nails, and skin rashes. Studies show biotin's benefits for hair restoration, with one experiment demonstrating significant hair growth after three months of supplementation. Reports indicate that biotin enhances nail density and can also aid in lowering blood glucose for diabetes patients. Furthermore, biotin supports adrenal function and thyroid hormones, influencing various physiological processes. Insufficient biotin intake may lead to issues such as weight gain, fatigue, and sleep disorders. Overall, it promotes muscle tissue regeneration and aids in building muscle mass.

After one jar, I noticed much fine hair growth, and my hair now grows quickly while my nails have become harder and less brittle. I highly recommend this high-dose, good-quality biotin at a reasonable price.

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.

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.

It works! These genuinely work! I have hypothyroidism, and my hair falls out in clumps due to hormonal fluctuations. After stopping the weight loss pill Alli, I started taking biotin every night along with a multivitamin. Within weeks, I noticed new hair growth. My hair has grown about 4 inches and is now healthier and thicker. I highly recommend giving it a try; you should see results in around two months.

Leg Cramps details

Adequate muscle support

Most Useful Review

Great 21st Century Magnesium is a basic yet effective magnesium supplement. Formulated with magnesium oxide, it contains 110 tablets, each providing 400mg of elemental magnesium. This product supports muscle relaxation and nerve function, which in turn helps to reduce muscle cramps and enhances joint mobility. While it may not be the most absorbable form of magnesium, the high dosage compensates for this. Furthermore, the tablets are tasteless, making them easy to swallow. Overall, it is an affordable option for those needing support with muscle health and energy levels.

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.

Biotin treatment for eczema effectiveness

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.

After suffering from facial eczema for years, I decided to try biotin. A month in, my redness and eczema have significantly improved. Although it's said to take a year for complete resolution, I feel encouraged by the benefits and plan to keep using it. If you're struggling with eczema, I recommend sticking with it.
