What are Collagen and Biotin?
Collagen and biotin are dietary supplements that are often used to improve beauty. They are available in various forms like powder and capsules or added as ingredients for several beauty products. Some are adding them to nutritional food supplements as well.
Collagen
As we age, we develop some sagging skin, wrinkles, and weaker hair. That is where Collagen can come in.
Collagen, therefore, is a type of protein carrying a crucial role in maintaining the health of several body organs and tissues, including the muscles, bones, skin, and many more. The goal of this supplement is to increase its production to minimize the effect of aging. [1]
Biotin
Biotin is commonly known as vitamin B7. It is a water-soluble vitamin that helps our body digest the fats, carbohydrates, and proteins we consume. Because of its ability to support metabolism, it is said to help maintain healthy hair, skin, and nails. [2]
Collagen Vs. Biotin Benefits
Collagen and Biotin are best known for their hair and skin health support. The following are the details of their benefits and how they differ in terms of performing their duties.
Collagen Vs. Biotin for Hair Growth
Collagen:
According to research, Collagen is good at strengthening the hair follicles. Such activity leads to denser and thicker hair and reduced hair breakage. [3]
Biotin:
Biotin, on the other hand, facilitates keratin production. Keratin is a type of protein that plays a primary role in healthy hair growth. More specifically, it prevents hair dryness and maintains hair elasticity. [4]
Collagen Vs. Biotin for Skin
Collagen:
Research has proved that Collagen is great for improving skin elasticity and keeping the skin hydrated. This lets the body reduce the emergence of fine lines and wrinkles, which typically develop as we age.
Moreover, it also facilitates the process of skin repair. This contributes to a youthful-looking beauty. [5]
Biotin:
Biotin is a protein good for cell regeneration support. Its ability to help the body generate new cells promotes a healthy skin barrier, resulting in a smooth and glowing skin complexion. [6]
Collagen Vs. Biotin for Thinning Hair
Collagen:
Since Collagen supports health growth, we can expect it can also be a good support for individuals who notice their hair becoming thin. The nutrients contributing to the hair follicle’s strength ultimately lead to thicker and healthier-looking hair.
Biotin:
Similar to Collagen, Biotin can also facilitate hair growth. Its production of keratin supports the health of the hair shaft. In the long run, it leads to thicker hair.
Collagen Vs. Biotin for Nail Health
Collagen:
Studies say that Collagen is capable of strengthening nails. Specifically, it facilitates hydration in the nail matrix, which prevents dryness. This makes the nails less prone to cracking and remains flexible. Thus, those with enough Collagen in the body have reduced brittleness in their nails.
Moreover, Collagen improves cuticles’ health. Cuticles are the skin’s thin layer protecting the nails’ base. It results in a firm boundary against infections and, thus, promotes healthy nails. [7]
Biotin:
As mentioned, Biotin contributes to Keratin production. This protein plays a role in maintaining nails’ structure. Moreover, Biotin is good at moisture retention, preventing the nails from drying excessively. [8]
Collagen Vs. Biotin Other Benefits
Collagen:
Aside from the health benefits mentioned above, Collagen also positively contributes to joint and cartilage health. It further supports bone density which helps people have a reduced risk of developing osteoporosis and other bone-related issues.
Lastly, it supports gut health. The amino acids Collagen contains support the gut lining, which helps promote a healthy digestive system.
Biotin:
Like Collagen, Biotin also comes with some more health benefits other than the ones that had been mentioned earlier. It provides good support for metabolism.
It helps the body convert nutrients like carbohydrates and proteins into energy. Some say that it can also support fetal development, preventing some possible birth defects.
Collagen Vs. Biotin Side Effects
Like other supplements, Collagen and Biotin also have their own side effects. Here are some of them.
Collagen:
Generally, Collagen supplements are safe to use. However, some individuals may experience minimal side effects like the following:
- Allergic Reactions like mild skin irritation and itching
- Difficulty breathing (rare)
- Bloating
- Stomach upset
Biotin:
Like Collagen, Biotin is also generally not harmful. However, some individuals may experience the following side effects:
- Skin rashes
- Acne breakouts
- Nausea
- Cramps
- Diarrhea
- Stomach upset
- Allergic reactions like itching, swelling, or difficulty breathing (rare)
Collagen Vs. Biotin Which Is More Effective
In terms of efficacy, Collagen vs. Biotin come with their own sets of strengths. Thus, when choosing which product you want to buy, it is essential to know your goal.
For instance, when talking about hair growth and skin health, both supplements can have their contribution. However, Collagen offers a broader scope of benefits. Likewise, it also promotes bones, joints, and muscle health.
Meanwhile, Biotin has narrower benefits. That includes pregnancy and metabolism support.
Conclusion
Collagen and Biotin are both helpful in sustaining skin and hair health. They also come with other benefits; choosing which one to take depends on your goal.
While they are generally safe, it is still best to consult your health provider before taking any of them. Unusual reactions must be reported immediately to avoid complications, especially if you have allergies.
