Chromium and biotin affect diabetes
Combination of chromium and biotin improves coronary risk factors in hypercholesterolemic type 2 diabetes mellitus: a placebo-controlled, double-blind randomized clinical trial.
Low relevance for cholesterol treatment
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.

Successful hair regrowth
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!

Dramatic hairfall reduction
My hairfall has dramatically decreased from the second day of taking biotin. After starting with 10,000 mcg for two days, I reduced to 5,000 mcg. In one week, I've noticed a positive change where my hairfall has reduced by 80%. Highly recommended!

Effective hair revitalization
This product was taken at a critical dose of 10,000 mcg for severe hair loss. The high dosage turned out to be very effective as hair fall ceased within a month, and my hair appeared healthier. I recommend this for maintaining hair's beauty and health.

Positive hair growth
Satisfactorily, I have been drinking for about a month and I am starting to see results. It is pleasantly pleasing; new hairs have appeared, not just for me but also for my boyfriend. He had a bald spot at the temples, but after taking the pill, small hairs began to appear in that area. I hope it will help restore hair growth and density. 🙏🏻 I am attaching a photo to demonstrate the results and instil confidence in its efficacy.
