Kintainutri® Vitamin B7 D Biotin Powder Factory
Kintainutri® offers D-vitamin D with a purity of 99% and a low price of 1%. Biotin is a water-soluble vitamin, also known as vitamin B7 or vitamin H, that plays a vital role in the biochemical processes of many organisms. It can be obtained through chemical synthesis or from natural sources such as food.
Biotinylation is commonly used in biological laboratories to label and detect specific molecules or proteins, where biotin binds to the molecule or protein to be detected, and the target molecule can then be detected or purified through specific interactions between biotin and other molecules.

Is Vitamin H B7 D Biotin Powder Water Soluble?
Yes, Vitamin B7/D-Biotin powder is considered a water-soluble B-vitamin, meaning it dissolves in water and is excreted via urine. However, it is only sparingly soluble in water at room temperature—about 22g/100 ml—and is more soluble in hot water or specialized solvents.

What is Vitamin B7 D Biotin Powder Good For?
Vitamin B7 Benefits For Hair
D-Biotin is an essential coenzyme in keratin synthesis, and keratin is the main protein that makes up the core structure of hair. Supplementing with D-Biotin helps strengthen hair strands, reduce breakage and hair loss caused by fragile hair, and improves nutrient supply to the hair roots, promoting healthy hair growth from the source. Long-term adequate intake helps increase hair diameter, making hair appear thicker and fuller, and is especially suitable for people with hair problems due to biotin deficiency.
Vitamin B7 D Biotin For Skin
Studies have shown that its main benefit to the skin lies in its ability to support a healthy skin barrier function, helping to maintain the moisture and elasticity of the stratum corneum.
As a coenzyme involved in fatty acid synthesis, biotin helps improve dry, flaky, and rough skin, and also alleviates some types of dermatitis or rashes caused by deficiency.
Simultaneously, it promotes keratin production, making the skin more supple and smooth. However, for people with a balanced diet, the effects of additional biotin supplementation are usually only seen in the deficiency state; excessive intake has limited benefits for improving healthy skin.
