Those with joint discomfort may appreciate the soothing effect as I experienced less stiffness after a few weeks, an unexpected but welcome change. Above all, what strikes me is how this product feels like a natural part of my diet rather than a supplement.

After a few weeks, I noticed my nails strengthening and less brittleness, a welcome change. It wasn’t just my nails; my skin seemed to attain a certain glow. I’ve tried various supplements, but the bioavailability of this collagen made a visible difference.

3. Sunwarrior Shape Chocolate

unwarrior Shape Chocolate

Customer Satisfaction: 90%

Sunwarrior Shape Chocolate makes my top 3. It is a blend of pea protein, brown rice protein peptides, along with other wholesome ingredients, not only supports my muscle growth and recovery but also aids in managing my weight, which has always been a priority for me.

The chocolate flavor is quite enjoyable, making it a treat when added to my smoothies or just mixed with almond milk. The vitamins included, like vitamin C and biotin, contribute to the health of my skin and hair, and I’ve noticed a certain glow and strength to them since I started using this powder.

A potential downside I noticed is that the powder doesn’t dissolve as effortlessly as I’d like it to, sometimes leaving a bit of a gritty texture. I found that blending it a little longer than usual or using a shaker bottle helps achieve a smoother consistency.

  • Plant-based ingredients
  • No added sugars

  • Slightly grainy texture may require thorough mixing
  • Taste may vary for individuals, some finding it not to their preference

Further Food Chocolate

Customer Satisfaction: 77%

I just tested Further Food’s Chocolate Collagen a couple of days ago. I must say that even through I didnt enjoyed it as much as I believed, it really is one of the best out there. The dark chocolate flavor melds perfectly with my brew, and it’s reassuring to know that I’m taking steps to enhance my skin’s elasticity with every sip.

Mixing this collagen into my post-workout smoothie was a breeze, which was the case at the time of my testing. The powder blended seamlessly, and I felt satiated for hours. My good friend, who also uses this product, noticed less hair shedding in the shower, which is a massive win for someone concerned about hair health.

Despite the rich flavor, Further Food ensures that sugar isn’t part of the deal, which aligns with my keto dietary preferences. Nevertheless, I did experience slight nausea initially, which settled after a few uses. So, my advice is to start with a smaller serving to allow your body to adjust.

What I liked
  • Indulgent chocolate flavor satisfies sweet cravings
  • Promotes skin, hair, and nail health effectively
  • Incorporates well in various beverages and snacks
What I didn't like

I’ve heard from many sources about how hair felt more resilient and nails grew stronger after consuming Dr. Colber’s Keto Zone.

I appreciate that it doesn’t cause a sugar spike, making it a great addition to a morning smoothie. The hydrolyzed collagen seems to be highly bioavailable, as I’ve felt a positive difference in my joint mobility. Mixing it into hot beverages works best; otherwise, it can take a bit of effort to avoid clumps.

Once dissolved, it’s virtually tasteless, which is ideal for combining with other flavored ingredients. Those who prefer tasteless over flavored options might look at the best options for their needs.

For those focusing on dietary restrictions, the powder is gluten-free, non-GMO, and lactose-free, fitting a variety of health preferences.

Nature’s Truth Multi Collagen Powder has become a crucial part of my dad’s morning ritual. I must say that I do not fully understand why he prefers it over other options, but from what he told me, and after m testing it, I can comfortably say it really is among the best one on the market at the moment.

The fine texture of the powder makes it incredibly easy to mix into breakfast smoothie or even just a glass of water. It’s reassuring to know that starting a day by giving our body important building blocks it requires. Committing to a keto and paleo lifestyle has its challenges, especially when it comes to finding appropriate supplements.

Customer Satisfaction: 74%

Best Naturals Multi Collagen is a solid way to start a day with a cup of coffee. It can easily become a seamless habit. The powder’s solubility is impressive, leaving no clumps behind, which I greatly appreciate as I dislike grainy textures in any drinks.

Despite the benefits, it’s worth mentioning that there is a distinct taste and smell to this unflavored powder. Initially, it was a little off-putting, but with continued use, I’ve found ways to mask it effectively in flavored beverages and smoothies. It’s been a small concession to make for the noticeable health improvements.

As someone who appreciates straightforward, clean ingredients, the absence of additives like artificial colors and flavors in Best Naturals Multi Collagen aligns with my preference for more natural supplements.

However, those with dietary restrictions should note that it does contain egg and fish, and if you have sensitivities or allergies, it’s wise to consider this before purchasing.

  • Noticeable effects on skin and nails
  • Dissolves well in liquids
What I didn't like

9. Nature’s Truth Peptides


Customer Satisfaction: 60%

I used Nature’s Truth Collagen Peptides for a few weeks, and the ease with which the fine powder blends with any beverage is quite good. No clumps or texture changes, just a smooth integration that doesn’t disrupt the enjoyment of the drink.

The benefits to my skin didn’t take long to materialize, but again they didnt last too long before. That is why I ultimately changed the product I use. Also, I did have a bit of a quibble with the container size, which seems a tad petite for my liking, especially since I use it daily.

Additionally, while the unflavored nature of the powder is usually a plus as it doesn’t alter the taste of my foods or drinks, there have been moments where I’ve yearned for a hint of flavor.

What I liked
  • Mixes easily into both foods and beverages
  • Noticeably improves skin radiance
  • Fits well with ketogenic and paleo dietary plans
What I didn't like
  • Container size feels a bit small
  • The unflavored taste may be undesirable to some
  • Reported discrepancies in the number of servings

Customer Satisfaction: 71%

The final product I want to address is California Gold Nutrition’s CollagenUP. It is a product that countless people around me used for a while, and I was fortunate enough to test it a couple of times.

Even though I can understand the positive opinion of many people, I simply didnt like it. The reason is quite simple: the taste is not what I expected. At the same time, the aftertaste is another thing that I had problems with.

The most positive side I noticed is how easy it blends in a beverage, regardless of your choice. If you are someone who dones’t know where to start, this one just might be the option that can determine later choices, which is not a bad thing if you think about it.

What I liked

  • The product is free from gluten, GMOs, or soy

Buying Guide

Best Tested Collagen Powders Buying Guide

Now, let us take a look at some of the most important factors you need to pay attention to before purchasing collagen powder.

Collagen Types

Collagen, a vital protein in the human body, is available in several forms as supplements, each catering to different health needs. Understanding these types is crucial for choosing the right supplement for your specific health goals.

Type I Collagen

This is the most abundant collagen type in the human body and is crucial for maintaining the health and structure of skin, hair, nails, and bones. Type I collagen is known for its ability to promote skin elasticity and hydration, potentially reducing wrinkles and dryness.

It also plays a significant role in strengthening nails and hair. In terms of bone health, Type I collagen helps in maintaining bone density and can be beneficial in preventing bone-related conditions as we age.

Type II Collagen

Primarily associated with joint and cartilage health, Type II collagen is essential for those looking to support their joint function. It’s found in the elastic cartilage that cushions the joints, making it particularly beneficial for individuals suffering from joint-related issues or those involved in heavy physical activity that puts stress on the joints.

Regular intake of Type II collagen can aid in reducing joint pain and inflammation, and it’s often recommended for people with arthritis or joint degeneration.

Type III Collagen

Often found in the body alongside Type I, Type III collagen supports the structure of muscles, organs, and blood vessels. It plays a critical role in maintaining cardiovascular health by contributing to the elasticity of blood vessels.

Additionally, Type III collagen is important for the skin, particularly in the healing process, and for the elasticity of the skin. It’s also beneficial for muscle health and can be an important supplement for athletes or individuals engaged in regular physical activity.

Each type of collagen has its unique benefits, and they are often taken in combination to support overall health and well-being. For instance, a combination of Type I and III collagen supplements can be particularly beneficial for enhancing skin health, while Type II is more focused on joint and cartilage support.

When choosing a collagen supplement, it’s important to consider your specific health needs and goals to select the most appropriate type.

Source and Quality

When selecting collagen supplements, the source and quality of the collagen are paramount factors to consider, as they directly impact the effectiveness and safety of the product.

  • Bovine Collagen: This type of collagen is derived from cows and is particularly rich in Type I and III collagen. Bovine collagen is a popular choice for those looking to improve skin elasticity and bone strength.
  • Marine Collagen: Extracted from fish, marine collagen is known for its high bioavailability, meaning it’s generally absorbed more efficiently by the body compared to other sources.
  • Poultry-Based Collagen: Sourced from chickens, this type of collagen is rich in Type II collagen, which is particularly beneficial for joint health.

The quality of the collagen supplement is just as important as its source. High-quality collagen supplements should undergo third-party testing to ensure their purity and potency. This testing helps confirm that the product is free from contaminants and meets label claims.

It’s advisable to choose supplements that contain no added fillers, artificial ingredients, or unnecessary additives. The presence of such substances can dilute the effectiveness of the collagen and may lead to unwanted side effects.

When choosing a collagen supplement, it’s also beneficial to consider whether it includes other synergistic ingredients like biotin, which can further support skin, hair, and nail health. Biotin, often known as vitamin B7, works in tandem with collagen to provide a more comprehensive approach to beauty and health.


Collagen Powders Bioavailability

Bioavailability is a critical factor in the effectiveness of collagen supplements. It refers to the body’s ability to absorb and utilize the collagen after ingestion. Not all forms of collagen are equally bioavailable, which means that the body may not always absorb and benefit from the collagen consumed.

Hydrolyzed collagen, also known as collagen peptides, is a form of collagen that has been broken down into smaller, more easily digestible particles. This process of hydrolyzation reduces the protein into smaller peptides, which are more readily absorbed into the bloodstream.

As a result, hydrolyzed collagen tends to be more bioavailable compared to non-hydrolyzed forms. The increased bioavailability of hydrolyzed collagen means that it can be more effectively used by the body for various functions, such as repairing and rebuilding skin, bones, and joints.

This form of collagen is particularly beneficial because it ensures that a higher percentage of the ingested collagen is actually utilized by the body, rather than being wasted.

Additional Nutrients

it’s beneficial to consider products that include additional nutrients. These vitamins and minerals can complement and enhance the body’s natural collagen synthesis, providing a more holistic approach to health and wellness. Here are some key nutrients often added to collagen powders and their benefits:

Vitamin C

This essential vitamin is a powerhouse when it comes to enhancing collagen formation. Vitamin C plays a critical role in the synthesis of collagen by stabilizing the collagen molecules and increasing their production.

It’s not only vital for the maintenance of healthy skin but also for the overall integrity of connective tissues throughout the body. Including Vitamin C in collagen supplements ensures that the body has the necessary components to effectively utilize the collagen.

Hyaluronic Acid

Known for its incredible capacity to retain moisture, hyaluronic acid is a valuable addition to collagen supplements, especially for skin health. It supports skin hydration, helping to maintain a plump, hydrated, and youthful appearance.

The combination of hyaluronic acid and collagen can significantly improve skin elasticity and reduce the appearance of fine lines and wrinkles.

Amino Acids

Collagen is made up of various amino acids, the building blocks of proteins. Supplementing with additional amino acids can aid in the production of collagen in the body. Specific amino acids like proline, glycine, and lysine are particularly important for collagen stability and synthesis.

By including these amino acids, collagen supplements can be more effective in supporting the body’s collagen needs.

Certifications and Dietary Needs

I pay close attention to various certifications and how the product aligns with my dietary needs. These factors are crucial in determining the quality, source, and safety of the collagen, ensuring that it meets my personal health standards and preferences.

Grass-Fed Certification for Bovine Collagen

When choosing bovine collagen, I look for products labeled as ‘Grass-Fed.’ This indicates that the collagen comes from cows that were raised on pastures and fed a natural diet. Grass-fed cows are generally healthier, and their collagen is considered to be of higher quality.

This type of farming is also more environmentally sustainable and ethical, which is important for my personal consumption choices.

Wild-Caught for Marine Collagen

For marine collagen, I prefer products labeled as ‘Wild-Caught.’ This term suggests that the fish used for the collagen were caught in their natural habitats, which often leads to a better nutritional profile.

Wild-caught is also a marker of sustainability, indicating that the product was sourced in a way that is less harmful to the environment and supports the natural ecosystem.

Quality Certifications

Certifications from reputable organizations like NSF (National Sanitation Foundation) or USP (United States Pharmacopeia) are key indicators of a product’s quality and safety. These certifications mean that the collagen supplement has undergone rigorous testing and meets high standards for purity and potency.

I always feel more confident in a product’s safety and efficacy when it has these certifications.

Compatibility with Dietary Restrictions

It’s essential for me to ensure that any collagen supplement I choose is compatible with my dietary needs. This includes checking for labels like gluten-free, non-GMO, dairy-free, or any other specific dietary requirements I have.

These considerations are important not only for allergy reasons but also for ensuring that the supplement aligns with my overall health and wellness goals.

Powder vs. Pills vs. Liquid Collagen

One of the key decisions involves choosing the form that best suits your lifestyle and preferences: powder, liquid, or pills. Each form has its unique advantages and considerations, ranging from ease of use and absorption rates to convenience and taste.

Understanding the differences between these forms can help you make an informed decision that aligns with your health goals and daily routine.

Feature Powder Collagen Liquid Collagen Collagen Pills
Absorption Good, depends on digestive process Often faster due to pre-dissolved state Good, depends on digestive process
Convenience Requires mixing, versatile in use Ready to drink, no preparation needed Highly convenient, no preparation
Dosage Control Flexible, can adjust serving size Pre-measured, less control Fixed dose per pill
Taste Neutral or flavored, depends on the product Varies, often flavored Usually tasteless
Portability Easy to transport, requires a container for mixing Bulky, but no extra tools needed Highly portable, discreet
Suitability for Recipes Ideal for adding to foods and drinks Not typically used in recipes Not suitable for recipes
Shelf Life Generally long when stored properly Can vary, some require refrigeration Typically long shelf life

If you don’t think that my picks are enough for you to make a decision, take a look at some alternatives:


What is better marine collagen or collagen peptides?
Marine collagen, sourced from fish, is rich in Type I collagen which is ideal for skin, hair, and nails. Collagen peptides, on the other hand, can come from various sources and are more easily absorbed. The choice between marine collagen or collagen peptides depends on your dietary preferences and specific health goals.
Is 55 too late to start taking collagen?
No, it’s not too late. Starting collagen supplementation at age 55 can still provide benefits such as supporting skin health and potentially improving joint comfort. Age shouldn’t be a deterrent when considering collagen supplements.
How long is it OK to take collagen?
Collagen supplements can be taken indefinitely as part of a daily routine. There’s no established timeframe for taking collagen, but consistency is key for potential benefits to skin, bone, and joint health.
Is it worth taking collagen after 60?
Taking collagen after 60 can be worth it, especially as natural collagen production declines with age. Supplements may help improve skin elasticity and support joint and bone health among older adults.
Is it better to take collagen in the morning or at night?
The time of day you take collagen might not significantly impact its effectiveness. Some prefer taking it in the morning as part of their start-the-day routine, while others take it at night, believing it works in tandem with the body’s natural repair processes during sleep. Choose a time that aligns with your schedule and stick to it.

Final Reflection

In evaluating the best tested collagen powders, I considered a variety of factors, including source, bioavailability, additive content, and dietitian recommendations. The options I’ve outlined above provide high-quality choices that cater to different dietary needs and preferences.

My personal pick is Ancient Nutrition’s Bone Broth.

The advice I offer is drawn from rigorous testing and expert input, aiming to give you the most reliable and beneficial options. Remember to consult with healthcare professionals before starting any new supplementation to determine what best suits your individual health needs.

When integrating collagen supplements into your routine, consistency is key for noticeable benefits. It’s also important to maintain a balanced diet and a healthy lifestyle to support your overall well-being.
