Looking for the ultimate collagen boost but unsure which collagen supplement is best? With so many options—bovine, marine, and even so-called ‘plant-based’ collagen (spoiler: it doesn’t contain real collagen)—it’s easy to feel overwhelmed. That’s why I’m thrilled to introduce the best collagen supplement of 2025: Marine Hydrolyzed Collagen—formulated for superior absorption and proven results! it's the most abundant protein in our bodies, serving as a vital building block for our skin, bones, muscles, tendons, and ligaments. It plays a crucial role in maintaining the structure and elasticity of our tissues. As we age, our natural collagen production decreases, leading to signs of aging such as wrinkles, joint pain, and reduced skin elasticity. This makes collagen supplementation an appealing option for those looking to support their overall health and maintain a youthful appearance. In this post, we explore the best collagen supplements of 2025: Marine Hydrolyzed Collagen vs. Bovine Collagen.
Personal Experience
Having explored the world of collagen myself, I’ve learned firsthand how important it is to make an informed choice. Whether you’re looking to improve your skin, hair, nails, joints, or overall health, choosing the best collagen for your needs makes all the difference.
My own journey began with grass-fed bovine collagen, a long-time standard collagen made from cattle hides and bones. But it wasn’t until I switched to marine hydrolyzed collagen, the new superstar collagen derived from fish scales and skin, that I noticed a real difference in my health.
Unlike bovine collagen (or porcine collagen derived from pigs), marine collagen offers a safer, more sustainable, and promising alternative. It boasts high bioavailability and potency, meaning it’s more easily available and absorbed by the body. Additionally, marine collagen comes with a lower risk of transmissible diseases, is free from religious concerns, and is both eco-friendly and cost-effective.
3 Key Tips for Selecting A Marine Collagen Supplement
Prioritize hydrolized collagen. This form has been broken down into smaller peptides, making it easier for your body to absorb.
Choose brands that guarantee transparency in sourcing and undergo third-party testing. This is particularly important to ensure you’re getting a safe, high-quality product free from or compliant with established levels for contaminants like PFAS, heavy metals, and microbial impurities.We lose about 1% of collagen every year starting in our 20s, and this rate accelerates to a staggering drop of up to 30% during menopause. Incorporating a high-quality collagen supplement into your routine can be a game changer. I wish I had known about collagen years ago; I believe it would have helped me feel my best much earlier in life.
Aim for collagen products that deliver 5 to 10 grams per serving. Research suggests that a daily intake of 5 to 10 grams can help improve skin elasticity, hydration, and overall appearance, while also supporting joint health and reducing the risk of joint-related issues. Moreover, this dosage can enhance muscle mass and aid in recovery after exercise, making it particularly beneficial for athletes and active individuals.
Consider the type of collagen in your supplement. There are 4 main types—Type I, Type II, Type III, and Type IV—and each plays a unique role in our body:
• Type I: The most abundant form; found in skin, tendons, and bones. It helps maintain skin elasticity and firmness and is crucial for anti-aging.
• Type II: Primarily found in cartilage; it supports joint health and reduces pain and inflammation. This is particularly important as we age.
• Type III: Often found alongside Type I; it contributes to the structural support of muscles, blood vessels, and organs. It also aids in tissue regeneration and repair.
• Type IV: Located in the basement membrane of various tissues, it plays a key role in filtration, particularly important for gut health.
Incorporating a blend of different collagen types into your diet provides comprehensive support for skin, joint health, muscle vitality, and overall wellness.
The Impact of Menopause on Hair Health
Menopause brings a host of changes for many women, including thinning hair and increased shedding. I experienced this firsthand—during menopause, my hair became noticeably thinner, leading to concerns about bald spots. However, after incorporating collagen into my routine alongside my Supergreens Shampoo and Conditioner along with the Supergreens Scalp Treatment and Armra, (15% Off on your first order). I began to see a remarkable transformation. My hair is finally growing back in areas where I was once nearly bald.
The Benefits of Hydrolyzed Collagen with Vitamin C
Combining hydrolyzed collagen with vitamin C can significantly enhance the benefits of collagen supplementation. Vitamin C plays a crucial role in collagen synthesis, as it is required for the enzymatic processes that stabilize and cross-link collagen molecules. Taking vitamin C alongside collagen can improve the efficacy of the collagen you’re consuming.
Recommended Vitamin C Intake
For optimal results, it’s typically recommended to consume about 500 to 1000 mg of vitamin C per day if you are taking it as a supplement. If you prefer to get your vitamin C from food sources, aim for at least 75 mg per day for women and 90 mg for men. Some of the best food sources of vitamin C include:
Oranges and other citrus fruits: 1 medium orange contains about 70 mg
Strawberries: 1 cup contains about 85 mg
Kiwi: 1 medium kiwi contains about 71 mg
Bell peppers: 1 cup of chopped red bell pepper contains about 190 mg
Broccoli: 1 cup cooked contains about 102 mg
Brussels sprouts: 1 cup cooked contains about 97 mg
Best Time to Take Collagen
For optimal absorption, it’s generally recommended to take collagen on an empty stomach, ideally first thing in the morning or at least 30 minutes before a meal. This helps ensure that your body can effectively absorb the collagen peptides.
Supporting Research
A recent study published in Nutrients (2024) examined the effects of a daily dose of 5 g of hydrolyzed collagen combined with 80 mg of vitamin C, with some participants also receiving 30 mg of hyaluronic acid. Over 16 weeks, the study showed beneficial effects on skin parameters, including improvements in dermis density and skin texture, as well as a reduction in the severity of wrinkles. Notably, the addition of hyaluronic acid did not yield superior effects compared to collagen alone. This study supports the idea that collagen, especially when paired with vitamin C, can be effective in addressing skin aging, particularly for menopausal women.
The Pure Haven Difference
What sets Pure Haven apart is our commitment to quality and purity. Our wild-caught marine collagen is harvested from clean white fish like cod, haddock, and pollock found in the pristine northern Atlantic waters off Canada—areas known for their low pollution levels. This ensures that our collagen is free from direct exposure to antibiotics and hormones.
Pure Haven’s collagen is manufactured in-house at a USDA Certified Organic facility, ensuring strict quality control. We do not use additives, preservatives, fillers, or bulking agents, meaning you get the purest product possible without toxins or compromises. Each batch undergoes third-party testing for heavy metals, ensuring safety and purity.
With a blend of Types I, II, III, and IV collagen, our product supports skin, hair, nails, and joint health while promoting the repair and regeneration of connective tissues and gut health. Plus, our marine collagen is easily digestible, dissolves well in both hot and cold beverages, and has no taste, making it a convenient addition to your daily routine.
If you’re considering a collagen supplement, I highly recommend trying Pure Haven’s marine hydrolyzed collagen. After taking bovine collagen for over six months with little to no results, I noticed a significant improvement in my joints and nail strength after just one month of using Pure Haven's product.
By making an informed choice about your collagen supplement, you can take proactive steps toward maintaining your health and vitality.
