PCOS, or polycystic ovary syndrome, is a common endocrine disorder that affects as many as 116 million women worldwide. While the cause of PCOS remains mostly a mystery, there's no doubt that dietary supplements can play a pivotal role in managing its symptoms. One such supplement that's been making waves recently is collagen. Is collagen good for PCOS? Let’s dive into the connection between collagen and PCOS and how collagen may help manage PCOS symptoms.

What Is Collagen?

In the vast symphony of proteins that make up the human body, collagen holds a vital role as the principal performer. It's not just any protein; it is the most prevalent one, making up approximately one-third of the body's total protein content. As a structural protein, it forms the backbone of our skin, hair, nails, bones, and joints, providing them with the strength, structure, and elasticity they need to function properly.

Skin Health

Collagen provides the skin with its firmness and suppleness, that youthful elasticity that allows it to snap back into place. It provides the building blocks for nail and hair tissues, promoting strength and growth. 

Joint and Bone Health

Collagen is also indispensable for our bones and joints. It helps to maintain the structural integrity of our bones and acts as a sort of “glue” that holds our joints together. It enhances the resilience of our tendons and ligaments, the structures that anchor muscles to bones.

Heart and Digestive Health

It is also instrumental in the health of our blood vessels and digestive system. It helps to maintain the integrity of the walls of our arteries, veins, and capillaries, which is crucial for cardiovascular health. In the digestive system, it helps to support and protect the lining of the gastrointestinal tract, aiding in digestion and nutrient absorption.

As we age, our body's collagen production naturally decreases. This results in the skin losing some of its elasticity and hydration, leading to the appearance of wrinkles and fine lines, which are common signs of aging. It can also lead to weakened bones and joints, increasing the risk of fractures and conditions like osteoporosis and joint pain.

It's safe to say that collagen is a protein powerhouse with wide-reaching effects on our health and well-being. Understanding the role of collagen can help us better appreciate its importance and consider ways to support our body's collagen production as we age.

What Are the Types of Collagen?

While there are 28 distinct types of collagen, the bulk of collagen present in the body typically belongs to one of the following five classifications:

  • Type I: Representing the lion's share of your body’s collagen at 90%, Type I is densely arranged, pivotal in providing structure to various parts of your body, including your skin, bones, tendons, and fibrous connective tissues.
  • Type II: Predominantly found in elastic cartilage, Type II collagen contributes significantly to joint health and mobility by providing cushioning and support.
  • Type III: Located in several vital areas such as muscles, arteries, and organ structures, Type III collagen is integral to maintaining the integrity and functionality of these body components.
  • Type IV: Primarily found in the various layers of your skin, Type IV collagen aids in fortifying the protective barrier between your body and the external environment, keeping it safe from harmful elements.
  • Type V: Uniquely situated in the cornea of your eyes, certain skin layers, hair, and the tissue of the placenta, Type V collagen is fundamental to ensuring clear vision and maintaining the health and strength of skin and hair.

Can Collagen Be Helpful for PCOS?

Although PCOS has a complex matrix of symptoms, some research suggests that collagen for PCOS could indeed have positive effects. PCOS often comes with metabolic syndrome, a condition characterized by insulin resistance, which can lead to elevated levels of insulin and testosterone in the body. These elevated levels can contribute to weight gain, irregular menstrual cycles, and even facial hair growth.

Collagen, however, can help balance these levels. Studies show that regular collagen supplementation can help manage blood sugar levels, potentially reducing insulin resistance. This can lead to better weight management, regulating menstrual cycles, and lessening other PCOS symptoms.

Benefits of Taking Collagen for PCOS

Taking collagen as a PCOS supplement offers a range of health benefits, especially for those managing PCOS:

  • Balanced hormone levels: Regular collagen supplementation may assist in balancing androgen and insulin levels in women with PCOS, helping to alleviate symptoms such as weight gain, hair loss, and irregular menstrual cycles.
  • Improved metabolic function: Collagen's role in blood sugar regulation can help improve metabolic function, reducing the risk of metabolic syndrome often associated with PCOS.
  • Healthy skin and hair: Collagen can aid in reducing symptoms such as acne and unwanted hair growth, common in women with PCOS. Plus, its well-known benefits for skin elasticity and hair health offer an added bonus.
  • Supports overall health: Regular collagen supplementation and a balanced diet rich in omega-3 fatty acids and probiotics can significantly improve overall health.

It’s important to note that there is a potential for collagen side effects on the menstrual cycle, and it is always advised to discuss any new supplements with your healthcare provider before starting. 


PCOS supplements, including collagen, can provide several benefits for women, from balancing hormone levels to supporting overall health. Though they are not a cure-all, they can be a valuable tool in the overall management of PCOS symptoms. The right blend of nutrients, as found in S’moo’s Build(her), can help to make living with PCOS a bit more manageable.
