Best Collagen Supplements for Perimenopause

Why Collagen Becomes More Important During Perimenopause

You might notice your skin feels thinner, less elastic, or slower to bounce back. Joints that never bothered you before now ache after exercise. These changes have a physiological explanation, and it connects directly to hormonal shift.

Estrogen plays a significant role in stimulating collagen synthesis throughout your body. When estrogen levels begin to fluctuate and decline during perimenopause, collagen production slows. Research estimates that women lose up to 30 percent of skin collagen in the first five years after menopause, with loss beginning even earlier in perimenopause. The same structural protein that keeps skin firm also supports joint cartilage, tendons, bone matrix, and gut lining.

Collagen supplements cannot replace the estrogen-driven production your body is scaling back. But they can provide the raw amino acid materials, particularly glycine, proline, and hydroxyproline, that your body needs to make whatever collagen it still can.

Types of Collagen: Matching the Type to Your Goal

Collagen is not a single compound. There are over 28 types in the body, but a few are most relevant for supplementation.

Type I collagen is the most abundant in your body and is found in skin, tendons, bones, and ligaments. Type III works alongside Type I in skin and blood vessels. Products marketed for skin elasticity and anti-aging typically contain hydrolyzed Type I and III collagen. Marine collagen (from fish) is predominantly Type I and is highly bioavailable, making it a strong choice for skin-focused goals.

Type II collagen is found primarily in cartilage and is what most joint-specific collagen supplements contain. It works by a different mechanism than Types I and III. Rather than providing building blocks, it appears to work via oral tolerance, where small amounts train the immune system to reduce its inflammatory attack on joint cartilage. If your main goal is joint comfort rather than skin, look specifically for Type II or undenatured Type II collagen products.

Hydrolyzed Collagen vs. Gelatin: Which Form Works Best

Hydrolyzed collagen (also called collagen peptides) has been broken down into smaller amino acid chains that dissolve easily in liquid and are more readily absorbed by the gut. This is the most studied form for supplementation and the one used in most clinical trials examining skin elasticity and joint outcomes.

Gelatin is partially broken-down collagen that gels in liquid when cold. It contains the same amino acids but in longer chains that are less bioavailable than peptides. Gelatin works well in cooking applications and does provide some benefit, but hydrolyzed peptides are better absorbed when taken as a supplement.

Most powdered collagen products you will find are hydrolyzed. Look for this on the label rather than just the word collagen. The distinction matters for how well your gut can process and deliver the amino acids to your tissues.

Marine vs. Bovine Collagen: What the Difference Means

Marine collagen comes from fish skin and scales. It is predominantly Type I, which makes it particularly relevant for skin goals. It is also the most bioavailable form of collagen peptides because the molecular weight of marine collagen is smaller than bovine, meaning it absorbs more efficiently. The main drawbacks are cost (typically higher than bovine) and taste, which some people find fishy, though quality products minimize this.

Bovine collagen comes from cow hides and connective tissue. It contains both Type I and Type III, making it a good general-purpose option. It is less expensive, has a more neutral flavor, and mixes easily into coffee or smoothies. It is the most widely available form and the most commonly used in the studies examining collagen supplementation.

For most women in perimenopause with combined skin and joint goals, bovine collagen peptides are a practical, cost-effective starting point. Marine is a reasonable upgrade if skin elasticity is the primary concern and budget allows.

What the Evidence Actually Shows

For skin, the evidence is reasonably consistent. Multiple studies examining hydrolyzed collagen supplementation, typically at doses of 2.5 to 10 grams per day over eight to twelve weeks, found improvements in skin elasticity, hydration, and reduction of visible fine lines compared to placebo. Effect sizes are modest but real. This is not a dramatic transformation, but measurable improvement in skin quality is a reasonable expectation with consistent use.

For joints, the picture is more mixed. Studies on Type II collagen and undenatured collagen showed benefit for people with osteoarthritis and exercise-related joint discomfort. One large trial found that athletes taking collagen peptides daily experienced less joint pain with activity after 24 weeks compared to placebo. But not all joint conditions respond equally, and if inflammation or structural joint damage is significant, collagen alone is unlikely to be sufficient.

For bone, collagen peptides have some early evidence, particularly in combination with calcium and vitamin D. One study in postmenopausal women found that collagen peptide supplementation over 12 months improved markers of bone formation. The evidence base here is smaller than for skin but growing.

The Vitamin C Factor: You Cannot Skip This

Collagen synthesis in your body requires vitamin C as a cofactor. It is not optional. Without adequate vitamin C, the enzymes that convert procollagen into the stable, triple-helix collagen structure cannot function properly.

This means that taking collagen peptides without also ensuring adequate vitamin C intake reduces the benefit. Most people who eat a varied diet with fruits and vegetables are not severely deficient, but taking your collagen with a vitamin C-rich food or a vitamin C supplement is a practical way to ensure you are not limiting synthesis at that step.

Some collagen products include vitamin C in the formula. Others do not. Mixing your collagen powder into a citrus juice or a smoothie with berries or kiwi is a natural way to combine both in one step.

What to Look for on the Label (and What to Avoid)

Look for hydrolyzed collagen peptides with a specified dose of at least 2.5 grams per serving. Products that obscure the collagen content inside a proprietary blend without disclosing individual amounts make it impossible to know if you are getting a therapeutic dose.

Certified third-party testing matters for supplements. Look for NSF International, USP, or Informed Sport certification, which verify that the product contains what the label claims and is free from prohibited substances. This is not universal in the supplement industry, so it is a meaningful quality signal.

Grass-fed bovine sourcing and wild-caught fish sourcing are worth prioritizing both for quality and sustainability reasons. Single-ingredient products, which contain collagen and minimal fillers, are generally preferable to products loaded with sweeteners, artificial flavors, or large proprietary blends.

Realistic expectations matter here. Collagen supplements support what your body is already doing. They are not a substitute for the broader tissue support that estrogen provided. Combining them with adequate protein intake, vitamin C, strength training (which stimulates collagen in tendons and joints), and adequate sleep gives you the best context for seeing real benefit.
