What is Biotin?

Biotin, also known as vitamin B7, is a water-soluble vitamin that plays a vital role in metabolism, gene regulation, and cell signaling. It’s a type of vitamin called a co-factor, meaning it helps enzymes break down fatty acids, glucose and amino acids so your body can function properly. While biotin gained fame as a beauty booster, it does more than keep your hair, nails and skin healthy.

Biotin 1% is a combination of both dicalcium phosphate and biotin.


Biotin is well-known for its benefits on hair, skin, and nail health and is commonly found in anti-aging creams and lotions. When taken orally, it may support healthy hair. Biotin may also help maintain healthy glucose levels and contribute to cardiovascular health. It also helps fortify the brain, support cognitive ability and mood, and promote feelings of well-being.

  • Supports healthy hair, skin & nails

Supplement Facts
Serving size: 100 milligrams
Serving per container: *
Amount Per Serving % Daily Value**
Vitamin B7 (as Biotin 1%)...1mg 330%
* Daily Value not established.
** Based on 2,000 calorie diet

DiCalcium Phosphate

Sugar, soy, dairy, yeast, gluten, and corn.

As a dietary supplement, take 100mg daily, or as directed by physician.

Serving Size & Timing

About 100mg of Biotin supplement is the recommended dosage per day. However, the FDA recommendation is for 300 mcg per day, which is notably lower in dose. Because the mixture contains 1% Biotin, only 1mg of the solution is actual Biotin. There are about 1,000 mcg in every milligram, so 100mg amounts to approximately 333% of the daily value of 300 mcg.


This particular mixture of Biotin 1% contains 99% DiCalcium Phosphate, which serves as a carrier. The powder is very fine and should be kept in a cool, dry area away from heat and light.


No specific side effects have been associated with Biotin, and even overuse results in very few reports of problematic symptoms. Because it is part of the B-Vitamin complex, any excess is excreted through the urinary tract.


This B vitamin can be found naturally in the human body in small quantities. It is usually located and stored in the brain, muscle and liver. Biotin can be found in dishes that include egg yolk, liver, nuts, grainy cereals, beans and legumes. While processed foods may still contain some level of Biotin, the heat involved in cooking and maintaining freshness of these processed food items may inadvertently kill a lot of the Biotin available in these sources. The fresher the foods are, the higher the levels of Biotin that will be found in them.

Biotin 1% dissolves easily in water, coffee, juice, and most other drinkable liquids that are water based. However, it is most efficient when it is taken with other B vitamins, so try to find a B-vitamin-rich drink to dissolve it into.

I love shopping here for my products because I never have to worry about the quality of the product that I'm getting. And the shipping is always fast. I have only been able to take the biotin a few times because I have so many other great products from here that I'm taking. I'd love to review it again once I've had a chance to really implement it!

Very, very pleased! ! !

I purchased Biotin 1% in hopes that it would help with hair loss issues along the edges and nape of my hairline. I began seeing hairs fill in where before I was seeing only scalp, that was within the first week of using. Second week in I am seeing some length albeit slowly, but, if I am seeing all this within a two week period, I feel pretty confident that the Biotin is truly working toward having my hair back after waiting for over a year and using a zillion other products that did absolutely nothing. I am very, very pleased!


Great product!

As always, Bulk Supplements has delivered another fantastic product :-) This version (the 1% Biotin) is easy to encapsulate and add to daily supplements. The powder is very fine and white.


Great product

I'm having bariatric surgery in just a few days. I need truly good, easily dissolvable supplements, that aren't full of unnecessary fillers, etc. I was very happy to find Bulk Supplements and will be ordering more products!!

Biotin was recommended by my doctor. I have MS and he said it would help me. It has helped me. I have less spasms than before. I would recommend Biotin to all MS patients.
