What is Collagen?
Collagen is one of the primary structural proteins found in the body’s connective tissues. In fact, it comprises approximately 30% of all proteins in your body! It’s essential for skin, bones, cartilage, connective tissue, hair, skin, nails, and other areas.
Collagen supplies various amino acids that can boost collagen and protein synthesis in the body while enhancing overall health.
Traditional diets were rich in collagen due to bone broths and nose-to-tail eating practices. However, modern diets are typically low (or even absent) in collagen, which is why supplementation can prove beneficial.
Additionally, as we age, collagen production naturally declines. Many classic signs of aging, such as joint pain and wrinkles, are partially related to decreased collagen levels.
Benefits of Collagen Supplements
Collagen supplements offer a broad range of potential benefits, some better researched than others.
Generally speaking, collagen supplements may provide the following health benefits:
- Healthier Skin
- Joint Support
- Healthier Hair
- Nail Support
Healthier Skin
The most well-researched benefit of collagen supplementation is improved skin health. Collagen may enhance skin hydration, firmness, and elasticity. Regular use could also reduce wrinkles and fine lines.
These benefits likely stem from collagen’s ability to boost collagen synthesis in the skin and prevent skin health deterioration over time.
Joint Support
Evidence also supports collagen supplements for joint health improvement. This occurs by strengthening the connective tissue surrounding joints. In fact, collagen can reduce joint pain and arthritis symptoms while enhancing joint flexibility and mobility.
Healthier Hair
Collagen supplement users may also experience healthier hair. Collagen provides essential nutrition for hair, potentially helping slow age-related hair damage. Specifically, collagen may improve hair thickness and fullness, slow hair loss, and promote shinier, more lustrous hair.

Nail Support
Finally, collagen likely supports nail health by enhancing collagen production in nails. Some research shows collagen can improve nail thickness and reduce brittleness.
How to Choose the Right Collagen Supplement for Hair
When selecting the right collagen supplement for hair, consider both general guidelines and specific concerns.
First, the collagen dose should be at least 2.5g to be effective, preferably in the 5 to 10g range per serving.
Consider the types of collagen offered as well. The more collagen sources included, the greater variety of collagen types present, likely making it more beneficial.
You may also want additional ingredients that support collagen synthesis and hair health, such as vitamin C, hyaluronic acid, or various antioxidants.
Safety and quality are equally important. We only recommend supplements made in cGMP, FDA-registered facilities, third-party tested (or individually tested), and fully transparent with labeling and information. If possible, choose supplements sourcing their collagen from grass-fed cows, pasture-raised chicken, wild-caught fish, and other quality sources.
Additional Information (FAQ)
Still have questions about collagen supplements for hair health? Below we’ve provided answers to common questions about collagen supplements and hair.

How long does it take for collagen supplements to work for hair?
This depends on various factors. Generally, it will likely take at least a few weeks before any noticeable benefits appear. It may take several months to achieve optimal results for hair fullness, thickness, etc. Keep in mind that it’s not a cure-all and cannot fully reverse hair loss or treat severe hair problems.
Does collagen really make my hair grow?
Collagen appears to indirectly support hair growth. The amino acids in collagen can promote increased hair-building proteins. Plus, it supports hair follicle strength and health, which may lead to hair growth and improved fullness.
Are there ways to get collagen in my diet to support hair health?
Yes. Most often, you can obtain collagen from bone broths, poultry with skin, or gelatin (which is essentially collagen in a different form).
However, most people will find it easier to achieve the recommended dose through supplementation.
Is there a limit on how much collagen I can take?
Collagen doesn’t appear harmful even in high amounts. However, it shouldn’t comprise more than 30% of your total daily protein intake. Generally, we recommend following guidelines of 2.5 to 15g per day, possibly up to 25g daily in some cases.
Are there side effects?
Collagen may cause digestive side effects, such as upset stomach, nausea, or bloating. It may also trigger allergic reactions in a small percentage of people.
Additionally, if supplements contain other ingredients like vitamin C, hyaluronic acid, or herbal extracts, these also carry potential side effects.
Always consult with your doctor before taking any supplement, especially if you take prescription medications, have chronic health conditions, or have concerns about side effects.
