Can Collagen Help Improve Brittle Nails?

Can Collagen Help Improve Brittle Nails? Hello everyone, I hope you are well. In today’s post, I will be sharing a guest post from Stephen Small. Stephen Small is the CEO of Clinic Nutrition, which has created a range of high-quality, broad-spectrum liquid supplements that are supplied to clinics and direct to the consumer. Stephen will be looking at the role of collagen in nail health and, in particular, if it can help improve the health of brittle nails. Brittle nails (onychoschizia) affect about 1 in 5 people and are more prevalent in women. It is a common cause of soft, thin, or splitting nails.

Can Collagen Help Improve Brittle Nails?

Our body’s natural collagen production slows down as we age, beginning around 30. Lower levels of collagen lead to lower levels of keratin which can make your nails brittle and more prone to breakage.

Keratin is the primary protein in nails that helps to maintain your nails’ integrity and strength. Also, 95% of the hair follicle is made from keratin and, an interesting fact, the rhinoceros horn is also made from keratin. The primary amino acids in keratin are: (2)

• Glycine
• Valine
• Serine
• Tryptophan
• Lysine
• Methionine
• Cysteine

Brittle nails (onychoschizia) affect about 20 in 100 people and are more prevalent in women. (1) It is a common cause of soft, thin, or splitting nails. It can also occur when our body is deficient in any of the amino acids mentioned above. A collagen supplement can boost amino acid levels and help maintain or improve nail health.

Most collagen tablet supplements contain low doses of collagen, typically less than 1,000mg or 1g. There is no clear guidance on the optimum daily amount of collagen, but higher strength, typically 8,000mg to 10,000mg (8g-10g) per serving per day, will be adequate for most people.

How Can Collagen Help Improve Your Nail Health?

Collagen is a structural protein and a crucial component of your skin, hair, nails, bones, muscles and other body parts. It contains almost all the amino acids that make keratin. Some foods —animal skin and bone broth— can naturally boost collagen levels in your body. However, it might not be possible for everyone to take these foods.

Moreover, long-term or high intake of red meat may increase the risk of (3)

• Diabetes
• Heart disease
• Colon cancer

Collagen for Brittle Nails: What does the science say?

Below, we take a closer look at the potential benefits of collagen supplements for brittle nails based on recent scientific evidence.

Collagen decreases the frequency of broken nails.

A 2017 Journal of Cosmetic Dermatology article states that a 6-month oral administration of collagen peptides promoted nail growth. It decreased the frequency of broken nails in women aged 18 and 50. (4)

Collagen reduces nail brittleness and peeling.

In an 8-week study, participants receiving a supplement containing collagen, hyaluronic acid, peptides, and lipids had significant improvement in: (5)

1. Nail cracking
2. Nail brittleness
3. Nail softness
4. Nail peeling

Collagen significantly improves nail roughness

The roughness of the fingernail plate improved significantly in those who took a fish-derived type 1 collagen hydrolysate for 12 weeks. (6)

So, taking a collagen supplement can help improve the health of your nails. For example, Cutizana from Clinic Nutrition is a liquid collagen supplement sold in salons and online. It contains 10,000mg (10g) of type 1 & 3 collagen to support skin, hair and nails, including all the amino acids for keratin production. In addition, Cutizana contains Biotin, Hyaluronic Acid, Silica and Vitamin C for a complete beauty supplement.

The Bottom Line

Collagen contains most amino acids found in keratin, the building block of your nails. When your body lacks these amino acids, your nails can become brittle and rough, resulting in breakage or splitting.

Thus, a collagen supplement can safely and effectively improve brittle nails and boost nail health.

When choosing a collagen supplement, read the ingredients label and confirm that it contains amino acids that make keratin.

I hope you enjoyed that.
