Difference between collagen and Biotin

Difference between collagen and Biotin

Collagen has several roles, such as assisting in blood clotting and offering structure to the skin. It is gaining popularity as an ingredient in body lotions and shampoo and a nutritional supplement. Biotin is a B vitamin, and it has a significant role in converting food into energy. Biotin assists to manage the level of blood sugars, boosting the health of nails and hair. The B vitamin also helps in a healthy pregnancy.

Understanding Collagen

Collagen is a primary building block for ligaments, bones, tendons, skin, and muscles. You can also find collagen in other body parts, such as teeth, blood vessels, and corneas. You can view collagen as the glue that holds things in your body together. Endogenous collagen is naturally produced by the body, while exogenous collagen is synthetic, originating from outside sources, such as supplements. [1] The synthetic version of collagen is ideal for cosmetic and medical purposes, such as to repair body tissues. Food sources of collagen include:

  • Chicken
  • Berries
  • Fish
  • Citrus fruits
  • Egg whites
  • Garlic
  • Leafy greens
  • Red and yellow vegetables
  • White tea
  • Soy
  • Cashews
  • Avocados
  • Herbs rich in collagen
  • Bell peppers
  • Tomatoes
  • Beans

While the above foods contain collagen, individuals who want a youthful and wrinkle-free skin and other health benefits opt for supplements to increase intake of collagen. Collagen supplements undergo hydrolyzation to break down the collagen into peptides for easy absorption and usage. The supplements are available in powder, tablets, and capsules.

Increasing Collagen Production

The body manufactures collagen that begins as procollagen by combining proline and glycine. The process utilizes vitamin C. You can assist your body to produce more collagen by ensuring that you have plenty of these nutrients:

  • Copper- Found in cocoa powder, lentils, sesame seeds, cashews, and organ meat
  • Vitamin C- Found in strawberries, citrus fruits, and bell peppers
  • Glycine- Found in gelatin, pork skin, and chicken skin
  • Proline- Found in cabbage, mushrooms, wheat germ, asparagus, egg whites, and dairy products

What Damages Collagen

Some factors drain collagen levels in your body. [3] Therefore, it is paramount to avoid these factors to keep your skin and body healthy for a long time:

  • Consumption of a lot of sugar
  • Smoking
  • Sunlight
  • Age
  • Autoimmune disorders
  • Genetic changes

Health Benefits of Collagen

  1. Improve Skin Health

Collagen is a primary component of your skin. It strengthens the membrane and benefits in hydration and elasticity. The body produces less collagen as you age, causing wrinkles and dry skin. You can take collagen supplements to slow the aging of the skin, reduce dryness, and wrinkles.

  1. Relieve Joint Pain

Collagen maintains the integrity of the rubber-like tissue, known as cartilage that protects joints. Older people are at a high risk of developing degenerative joint disorders. Collagen supplements reduce joint pain and enhance the symptoms of osteoarthritis in older people. [2] Also, athletes who take in more collagen experience reduced joint pain while resting and walking compared to those who don’t take the supplements. Collagen also reduces inflammation and better support of the joints.

  1. Prevent Bone Loss

Collagen constitutes a large percentage of your bones, giving them structure and keeping them healthy. Bone mass deteriorates in older people. A diet containing collagen increases bone density and reduces risks of bone fractures.

What is Biotin?

Biotin is a water-soluble vitamin, known as vitamin B7. It is found in an array of foods, and it plays an essential role in helping enzymes to breakdown fats, carbohydrates, and proteins in food. Without the process of food breakdown, your body cannot convert the food you eat into energy for performing daily tasks and hair growth.

Biotin also assists in regulating the signals that the body sends between cells. You can get vitamin B7 through a healthy lifestyle and balanced diet. The bowel produces biotin, and the body requires this vitamin in small amounts to support normal body functions. While biotin deficiency is rare, some of the symptoms include:

  • Thinning hair
  • Skin infections
  • Red, scaly rash around mouth, nose and eyes
  • Brittle nails
  • Conjunctivitis

You need to visit a physician if you experience any of these symptoms. Besides processing food into energy, biotin is essential in supporting healthy skin, nails, and hair. [5] You can maintain the ideal levels of biotin by consuming the following foods:

  • Pork
  • Nuts and seeds
  • Cooked eggs
  • Beef liver
  • Salmon
  • Sweet potato

Since the vitamin is water-soluble, the body is unable to store it. Therefore, you have to ingest biotin through the above foods frequently. You can opt for biotin supplements to add more biotin into your daily meals. People living with chronic medical conditions, pregnant and breastfeeding mothers, and people struggling with alcoholism are at a higher risk of biotin deficiency.

Health Benefits of Biotin

  1. Thickens Hair

Biotin stimulates hair growth, making your hair to thicken and look more lustrous. Also, it makes your hair appear healthier than usual. People who are struggling with stunt hair growth or medical conditions that cause lackluster hair should incorporate more biotin into their diets. You can opt for biotin supplements if you struggle with nutrient deficiencies.

  1. Improves Skin

People struggling with vitamin H deficiency have issues with the appearance of the skin. Some common problems they experience include dry and itchy skin, psoriasis and acne. [4] Incorporating biotin into your diet or supplements helps you to create youthful skin.

  1. Strengthen Nails

Biotin is famous for its ability to strengthen nails. A high dose of biotin enhances the health of your nails and thickens them. Supplements reduce nail breakage and splitting.

Similarities between Collagen and Biotin

Collagen and biotin have different molecular structures, other functions, and synthesis pathways. [6] But, the two have a few similarities, including:

  1. There are foods rich in collagen and others in biotin
  2. The two have medical applications
  3. Both improve the health of the skin

Difference between Biotin and Collagen

  1. The two molecules differ from each other in various ways, such as:
  2. The extracellular matrix of connective tissues synthesize collagen, while bacteria in the large intestines synthesize biotin
  3. Biotin is a vitamin while collagen is a protein
  4. The connective tissue hosts collagen while biotin is found in dietary supplements or food
  5. The body doesn’t synthesize biotin while collagen has about 20 genes coding for its different forms


Collagen and biotin are both necessary for body functions. The similarities between the two molecules are less than their differences. Collagen is a protein and biotin is a vitamin. But, the two molecules make up healthy skin and can be used for cosmetic purposes. You can get the full benefits of collagen and biotin through foods.
