Chromium and biotin affect diabetes
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.

Biotin is essential for hair vitality. I experienced severe hair loss but found this product, containing 10,000 mcg of biotin, to be wonderful. I noticed an improvement in hair freshness and strength, with significant reduction in hair fall within the first week. The product is effective and reasonably priced, and I commend iHerb for their excellent service.

I took this biotin as my hair was falling out excessively. After a month, this issue nearly resolved. The tablets are small, easy to swallow, and odourless, making it a very high-quality product for the price.

I always use supplements for hair loss but never got such impressive results as now with this imported Biotin. Even my nails are growing stronger! It has greatly decreased my hair fall, and I hope this issue will soon be resolved. Highly recommend!

Visible improvement
1 people found this helpful
I can't help but share my experience! My hair was falling out excessively, and none of the usual products helped. After using Biotin for two weeks, I've already seen results. My hair is falling out less and is growing actively. I still have more to explore with the product.

Reduced hair loss

After experiencing hair breakage, I consulted a trichologist who advised a high dosage of Biotin at 10,000 units. After two weeks, I noticed much less hair falling out while combing and washing my hair, and new hairs began to sprout.

Dramatic effects
1 people found this helpful
Biotin has had a dramatic effect on my hair growth. With a high dosage of 10,000, I recommend starting with a smaller amount first, like 5000 if needed. After two months, I noticed a significant amount of new hair growing while taking it alongside omega.

Reduced cholesterol levels
1 people found this helpful
Biotin helps maintain normal blood sugar levels, reduces cholesterol, and aids in burning fat. It's a splendid supplement for those with overweight and diabetes issues. After taking it for over a month and a half, I noticed hair loss reduced and growth accelerated. The dosage and price were also favourable. However, be cautious as high concentrations may affect some lab results.

No effect noted

Not satisfied! The dose is high enough, but there is no result. I drank 2 cans, and observed no changes. There were no adverse reactions to my body. I will order the same dose from a different company, albeit at a higher price. A miser pays twice, which applies to me.
