Everything You Need To Know To Find The Best hydrolyzed fish collagen manufacturers

Don’t freak: If you’re 25 years or older, you’re actually already experiencing collagen loss. But the good news is that the best collagen peptide supplements can lessen the blow. Naturally produced by your body, collagen is an essential protein that helps build and maintain skin, bones, and connective tissues. “Think of it as the body’s internal ‘glue’ that holds everything together,” says licensed nutritionist Britta Sather, LN. Our collagen levels slowly diminish as we age, affecting our skin, hair, joints, and more. “Without enough collagen, our joints wouldn’t move smoothly, our bones could become weak and fragile, and our skin would feel dry and lose its elasticity,” says Sather. “On top of aging, other factors like smoking, environmental pollution, excessive alcohol consumption, and poor nutrition can also speed up collagen loss.” Enter: collagen peptide supplements, a close cousin to the collagen supplements you might already be taking but more easily absorbed (more on their difference later).

Everything You Need to Know

What are collagen peptides?

Supplementation is essentially useless unless your body can absorb it. That’s where collagen peptides come in. Also known as hydrolyzed collagen, collagen peptides are short chains of amino acids derived from collagen, the most abundant protein in the human body. “Collagen is a structural protein that’s responsible for strength, flexibility, and support to tissues such as skin, bones, tendons, ligaments, and cartilage,” explains Ryan. “There are various types of collagen in the body, distinguished by their structure and where they are found. When the collagen is hydrolyzed, it becomes more bioavailable which means the body is more effective at absorbing it.”

What’s the difference between collagen and collagen peptides?

It all comes down to how the body absorbs collagen. “Collagen is the full-length protein found in skin, joints, and connective tissue, but it’s difficult for the body to digest in its natural form,” says Fazio. “Collagen peptides are smaller, broken-down pieces of collagen that are much easier to absorb and use as supplementation.” Gavini notes that collagen molecules are very large—around 300,000 daltons molecular weight—whereas collagen peptides are fragments typically about - daltons. Through a process called hydrolysis, the full-length collagen is broken down into smaller chains of amino acids. “If you’re taking a supplement to support skin, joint, or overall health, it’s likely collagen peptides,” adds Sather.

Are collagen peptides worth it?

As with many supplements, it depends. “If you’re experiencing signs of aging or simply want to give your body a little extra structural support, yes, collagen peptides can be a smart addition to your routine,” says Sather. “Just remember they aren’t a miracle, and they work best when paired with a healthy lifestyle, movement, good nutrition, consistency, and smart self-care habits (like sunscreen).”

It’s also important to understand how collagen peptides work. “When you ingest collagen peptides, your body doesn’t simply shuttle them to your skin or joints and ‘plug them in’ as collagen,” says Fazio. “Instead, they’re broken down into individual amino acids (like glycine, proline, and hydroxyproline) which are then absorbed and used wherever the body needs them. The presence of these specific amino acids may signal the body to ramp up collagen production in targeted tissues, but the process depends on having the right cofactors (like vitamin C) and adequate protein intake overall.” While collagen peptide supplements can work in a thoughtful, long-term routine, they don’t act as a direct transplant for collagen. “They support the internal rebuilding of collagen-rich structures—especially when taken consistently for 8 to 12 weeks,” adds Fazio.

What are the benefits of collagen peptides?

The benefits of collagen peptides are many—and they can improve skin, hair, nails, joints, bones, and gut health. Here, Fazio breaks down the potential (incredible) benefits you can anticipate when using a collagen peptide supplement:

Skin

• Supports skin hydration and elasticity
• May reduce the appearance of fine lines and wrinkles over time
• Contributes to skin-barrier resilience and repair

Hair

• Provides amino acids (especially glycine and proline) needed for keratin production
• May help strengthen hair structure and reduce breakage indirectly through nutrient repletion through adequate amino acid intake

Nails

• Can improve nail strength and reduce breakage

Joints and Bones

• Supports joint integrity by providing building blocks for cartilage
• May help reduce mild joint discomfort or stiffness, especially in active or aging individuals
• Contributes to bone matrix formation and density when paired with adequate protein and micronutrients

Gut

• Supplies amino acids that support the structural integrity of the gut lining
• May aid in maintaining mucosal health, though more human research is needed to confirm direct benefits

Key takeaways

• Most research indicates that collagen supplements are effective at doses ranging from 2.5 to 15 grams (g) per day for skin health benefits.
• We chose collagen products with added nutrients, like vitamin C, that also benefit skin.
• We think Vital Proteins Collagen Peptides Powder is the best collagen powder for skin health.

So, what type of collagen is best for the skin? Technically, all types of collagen, but if you want to go the extra mile, we recommend choosing a supplement that contains additional ingredients thought to enhance skin health.

We chose five collagen powders and one capsule option after evaluating their ingredients against clinical research.

Collagen is a type of protein found throughout your body. It’s in your skin, bones, joints, ligaments, tendons, tissue, and teeth.

Collagen in supplement form is most commonly derived from:

• bovine
• porcine
• marine sources

It can also be made synthetically from insect, yeast, and plant or mammal cultures, resulting in a lower risk of allergic reactions. People often use collagen supplements to promote skin health, as this protein has shown benefits for skin elasticity, hydration, and texture.

Though bovine collagen is more widely found in supplements, the body absorbs marine collagen better, and it’s less inflammatory and contains fewer toxins, according to research.

Most of our picks contain bovine collagen because it’s more common. However, our Ancient Nutrition pick contains marine collagen as well as bovine and other sources.

Additionally, Anthony’s Marine Collagen is a former top pick that’s made strictly from marine sources, but we decided not to include it in our main list since it does not contain additional ingredients that benefit skin health. However, it’s a good choice if you want a collagen powder sourced solely from marine sources.

We selected the products featured in this article based on the following criteria:

• Type of supplement: We included collagen supplements in various forms, including powders and capsules.
• Ingredients: We selected collagen supplements made with high quality ingredients, all of which are free of fillers and unnecessary additives.
• Third-party testing or certifications: Many of the products on our list have been tested or certified by a third-party organization to ensure safety and quality.
• Dosage: Most studies have evaluated the effects of collagen at doses of 2.5 to 10 g per day. We selected collagen supplements available in a wide range of doses so you can adjust based on your needs.

Hydrolyzed collagen has been broken down into smaller molecules. It may be easier for your body to digest and absorb than regular collagen.

The amount of time it takes to experience noticeable benefits after taking collagen supplements can vary. Some research suggests collagen supplements could improve skin elasticity and hydration within 4 to 12 weeks.

Collagen supplements are generally considered safe and are associated with few negative side effects when used as directed.

However, to ensure safety, it is important to purchase products that have been tested by an independent lab whenever possible. Additionally, be sure to consult a healthcare professional before adding any new supplements to your routine.

Some research suggests that collagen could help slow signs of aging. In fact, one review of 19 studies concludes that after taking a hydrolyzed collagen supplement for 90 days, it could:

• improve skin hydration
• decrease wrinkles
• improve skin elasticity

There is limited research on whether collagen can tighten skin. However, some studies have found that collagen supplements could potentially improve the appearance of skin by improving:

• skin elasticity
• hydration
• texture

Because collagen is derived from animal products, there are no vegan-friendly sources of collagen.

Some older research suggests that vegan collagen could be made using genetically modified yeast and bacteria. More studies are needed, though, and vegan collagen supplements are not yet readily available.

However, several vegan-friendly, collagen-boosting supplements are already on the market. These usually contain ingredients that support collagen production, such as vitamin C, but not collagen itself.

Alternatively, you can consume more vitamin C-rich foods, such as fruits and vegetables, to help naturally promote collagen production.

Collagen can fit into a ketogenic diet, as it is typically low in carbs and high in protein. However, to keep your carb intake low, be sure to check the ingredients label carefully and opt for products without added sugar.

Taking a collagen supplement can be an easy and effective way to help promote better skin.

Plenty of products are available, containing a range of doses and a variety of ingredients.

When deciding which supplement is right for you, consider:

• the type of supplement
• additional ingredients
• the dosage
• whether the product has undergone third-party testing

As with any supplement, consult a healthcare professional, like your primary care doctor, a dietitian, or a pharmacist, before adding collagen to your treatment regimen, especially if you have any underlying health conditions.
