Now, collagen is a household name.

Its popularity has increased exponentially in the last decade, with people—specifically women—flocking to it in hopes of reversing signs of aging (think: crepe-like skin, wrinkles, thinning hair, achy joints).

They’re not stopping, either. By , the collagen market is expected to be a 76.08 billion dollar industry (1).

In this article, we’ll reveal the seven most important things to look for when buying a collagen supplement—and most importantly—what to avoid.

Collagen is the most abundant protein in your body (it makes up about 30% of your total protein!).

Because of this, it’s often called the building block of your skin, muscles, bones, tendons, ligaments, and other connective tissues. It repairs several tissues in your body and plays a supportive role in skin health, bone mineral density, joint health, gut health, and more (2, 3, 4, 5).

Did you know that there are 28 distinct varieties of collagen (6)?

However, 90% of the collagen in your body is comprised of only Types 1, 2, and 3 (7).

Type 1 collagen is primarily found in your skin, bones, teeth, tendons, ligaments, vascular system, and organs. Type 2, although abundant, is found only in your cartilage (6). Type 3 is found in your skin, muscles, and blood vessels.

Supplementing with all three types of collagen seems best, but studies show that Type 2 inhibits the absorption of Type 1 and Type 3 (8). The ideal collagen supplement contains only Types 1 and 3 collagen.

Type 1 collagen positively impacts (9, 10, 5, 3, 11):

  • Osteoarthritis
  • Skin health (anti-aging)
  • Bone mineral density
  • Bone strength

Type 3 collagen positively impacts (5, 12, 13):

  • Skin health (anti-aging)
  • The health of blood vessels
  • Organ health (liver, kidney, lungs, heart)

Many companies market their collagen as “multi-collagen”, boasting that it contains several collagen types in one. Don’t be fooled: these added collagen fibers are filler fibers that take away the effectiveness of the more potent fibers like Type 1 and 3.

Collagen supplements can come from a variety of sources like bovine (cow), marine (fish), and even vegan options (yeast) (14). When it comes to bovine collagen, it’s essential that it’s grass-fed bovine.

Grass-fed cows are cows raised without antibiotics and hormones, and never fed genetically modified organisms (GMOs) (15).

Conventional beef is pumped with all kinds of chemicals like growth hormones (rBGH and rBST) and antibiotics that you shouldn’t be ingesting every day. 95% cows in the U.S. that are not 100% grass-fed are fed GMO corn (16).

To avoid these potential contaminants in your bovine collagen supplement, always look for “grass-fed” along with “non-GMO” on the label.

While there’s no set dosage for collagen, studies have confirmed that a 10 gram serving is ideal for your daily dose (17).

That said, there are several collagen supplements out there that offer a measly 2.5 or 5 grams of collagen per serving—barely enough to offer the transformational benefits that so many are after when taking collagen. (This is especially true for liquid collagen supplements.)

We recommend taking at least 10-20 grams of collagen peptides per day—and that’s if you’re just wanting to maintain collagen levels. If you’re 50 years old and just starting collagen, we recommend taking 40 grams of collagen for 8 weeks to replenish the collagen that you’ve lost over the years. And then lowering your daily dose back down to 20 grams.

Some research suggests that 2.5 to 5 grams is enough to notice changes in cellulite and skin elasticity, but not for more serious issues like sarcopenia (muscle loss due to aging), osteoporosis, or activity-related joint pain (18, 19, 20, 2).

4. “Hydrolysate”, “Hydrolyzed”, or “Peptides” on the Label

Hydrolyzed collagen and collagen peptides both mean the same thing: that the collagen has gone through a process that breaks it down into smaller, ready-to-absorb amino acids that can easily be soaked up by your body. Put simply, collagen peptides require much less effort from your digestion and guarantees a more potent dose of collagen (6).

Non-hydrolyzed collagen, on the other hand, requires your digestive enzymes to work harder.

The easiest way to tell if a collagen powder is truly hydrolyzed is if it doesn’t clump when you add it to coffee, tea, or water.

5. No Artificial or Chemical Ingredients

THINGS TO KNOW BEFORE TAKING COLLAGEN SUPPLEMENTS

If you’re well-versed on the health benefits of Collagen then you’re probably in the market to purchase. In order to make an informed purchase, it’s important you understand everything before picking a Collagen supplement for your usage.

1. Not All Collagen is Created Equal

The trickiest part of buying a dietary supplement is falling into the trap that they are all the same. If you’re sourcing an ingredient how could one jar on the shelf really be so different from the jar right next to it. First and foremost, you always want to buy “hydrolyzed” Collagen. In terms of quality and bioavailability that is imperative. Equally important, you want to look for grass-fed, pasture raised for Bovine Collagen and wild-caught for Marine Collagen. Supplementing the right Collagen not only benefits you, but also has a positive impact on the environment as the sources of Collagen from animals is often put to waste – i.e. fish scales, skin, bones.

2. Collagen Comes in Different Forms

The most common form of Collagen supplements is powder. However, if you do not like mixing the powders in food or drink and would prefer pills – they exist as well. The efficacy of the Collagen is the same in either powder or pills.

3. The Main Benefits of Collagen

There are many benefits to Collagen supplementation that are well-documented on our website. We cannot specifically call out a particular benefit but some clinically proven benefits are – joint pain relief, reduced inflammation, rejuvenated hair/skin/nails, improved digestive health, builds lean body mass – reduces fat/cellulite through appetite control, and much more.

WHAT ARE COLLAGEN
SUPPLEMENT BENEFITS?

The Collagen Dietary Supplement global market is projected to reach over USD$6 billion by according to Grand View Research. This number is driven by the healthcare sector with cosmetics having the largest impact on the total sales as of . However, the overall health benefits of collagen as a consumable dietary supplement is the main factor for growth over the next decade. The growing popularity is a direct result of increased consumer knowledge of the clinically proven health benefits of supplementing Collagen. Let’s break it down quite simply what those benefits are –

1. Promotes Healthy Joints & Ligaments

Outside of the cosmetic application of Collagen, one of the oldest tested benefits of supplementing is the impact it joints and ligaments. Studies go back to that cite collagen as reducing inflammation for arthritis patients. Modern day studies show overall preservation and restoration of connective tissue in the body. As you age, this is something that absolutely cannot be taken for granted especially if you’re an active person.

2. Reduces Visual Signs of Aging

The most well-known application of supplementing Collagen is the impact it has on your skin, hair and nails. There are a significant amount of studies that clinically show Collagen supplements to have reduced skin dryness, wrinkles and even cellulite. It even showed improved skin firmness in a period of 12 short weeks. On top of these positive benefits, it’s also shown to improve brittle nails as well as hair growth and quality. As stated, this one of the most well-known benefits of Collagen and there are studies to back it up.

WHO SHOULD TAKE
COLLAGEN SUPPLEMENTS?

Not Just a Supplement for Women!

“I am a 37-year old male. I’m a husband, a father and lead an active lifestyle. My health is very important to me, but like many I’ve tried a billion different things to fully optimize my overall wellness. I’ve had reconstructive surgery on my left knee, both of my shoulders have had enough tendinitis to choke a pig and I have about a half dozen other little physical hurdles that make it hard for me to feel like I’m at my best. I like to stay in good shape, avoid the dad bod, build lean body mass, but also make sure I’m functioning at a high level. I haven’t tried a few dietary supplements, I’ve probably tried hundreds. Anything from whey protein to fish oil to even fat burners. For a while, I was less concerned what was on the label and more concerned with what these random products could do for me. In hindsight, how stupid is that? Eventually, I started paying attention to what was in my dietary supplements and soon thereafter learned that about 80% of them have stuff in them I don’t want in my body. It was around this time I stumbled upon Zammex Nutrition’s Multi-Collagen Protein. Never in a million years did I think Collagen Peptides was something I should supplement – I’m not a female...”

The above is a true story from one of our loyal customers

Are There Collagen
Supplement Side Effects?

Is It Worth It?

Zammex Nutrition is built on the principle of Health Made Simple. Because of that we would never create a product that may have adverse side effects on our customers. However, it is vitally important that every person who chooses to take our products understands there may be side effects that aren’t anticipated. The good news is – Collagen as a dietary supplement has very few side effects. Because Zammex Nutrition’s products are derived from the best possible sources and remain totally pure, there are even fewer side effects. Here are a couple potential issues you should be aware of –

1. Hypersensitivity Reactions

There’s always a chance that you may have a hypersensitivity reaction as an abnormal response of the immune system against certain foods, drugs and supplements. While rare, it’s very important that you make sure you can consume Collagen prior to purchasing. Also, please be aware of the Collagen you are purchasing and the animal from which it came. For example, Marine Collagen comes from naturally caught Tilapia and could trigger a fish allergen. Whereas the Multi Collagen Powder contains Collagen from avian sources. Please inform yourself by reading our blogs or asking questions prior to consumption.

How To Choose A
COLLAGEN SUPPLEMENT?

1. “Hydrolyzed” Collagen

Without question you want to choose a Collagen that has the fewest ingredients as possible. Purity Realized is one of Zammex’s founding principles and should be in the forefront of your mind when picking a product. Ensuring your Collagen is hydrolyzed will optimize its bioavailability (absorption and usage) so you are maximizing every scoop you ingest.

2. Avoid the Flavors

If you’ve ever supplemented protein powders you’ve seen some flavors beyond your wildest dreams – The sports nutrition companies are quite creative! They are also quite good at loading those products up with artificial flavors, sweeteners and other nonsense that does nothing but run riot on your digestive system. For Collagen, Health Made Simple, no sweeteners, no artificial flavors or colors. Stay pure and mix it with something that brings foods natural flavor to your palate.

3. Third Party Certified.

The final prerequisite for a Collagen supplement is make sure it is Third Party Tested. The FDA doesn’t really have a handle on regulation, thus it’s important to look for UL, NSF or USP Certifications from these manufacturers. There are a lot of imitators out there without the proper certifications and they should be avoided. ZAMMEX makes an unflavored collagen peptides product the UL has certified.

Choosing the Right Marine Collagen Supplement - OOST Nutrition

Choosing the Right Marine Collagen Supplement

Marine collagen has become a popular choice in the health and wellness world, praised for its potential to support healthy skin, flexible joints, and overall vitality. As a great source of Type I collagen, which is the main type found in our bodies, it’s really important for keeping our skin, bones, tendons, and ligaments strong. It's worth remembering that collagen is only available from animal sources.  

With so many marine collagen supplements available now, it can be tricky to know which one will work best for you and deliver the benefits you’re hoping for. The quality and how well marine collagen works can differ quite a bit depending on how it’s processed, where it comes from, and how pure it is. To help you choose wisely, it’s good to know what makes a really good marine collagen supplement stand out. This section will guide you through the important things to think about when making your choice, so you can feel confident you're getting the best from marine collagen.

What to Look For When Buying Marine Collagen:

How Well It Absorbs: Why Hydrolysed Collagen Matters:

When collagen is in its natural state, it has large, complex molecules that our bodies find hard to digest and absorb properly. To help with this, collagen is often hydrolysed. This means the big collagen molecules are broken down into smaller pieces called peptides. This is usually done using enzymes, and the result is often called hydrolysed collagen or collagen peptides.  

These smaller collagen peptides have a much lower molecular weight, which means they dissolve better in water and are easier for our bodies to absorb. Once absorbed, these peptides can easily get into the bloodstream and travel around the body to support different tissues and functions. Interestingly, research suggests that hydrolysed marine collagen is absorbed even better than other types of collagen. Studies have shown it can be absorbed up to 1.5 times more effectively than collagen from cows or pigs. This better absorption means more of the collagen peptides you take can be used by your body to support your health. If you’re looking to get real benefits from marine collagen, especially if you’re active or have specific health goals, choosing a hydrolysed supplement is a really good idea.  

Keeping it Pure: Choosing a Safe and Effective Supplement:

Purity is something you really need to think about when choosing a marine collagen supplement. Fish, where marine collagen comes from, can sometimes store up things from their environment, including heavy metals like mercury, lead, and arsenic, which can be found in higher amounts due to water pollution. Taking in collagen that has these substances could be a risk to your health over time.  

That’s why it’s so important to choose supplements from trusted brands that do thorough purity testing. Look for products that have been tested by an independent third party, as this gives you extra confidence that the supplement contains what it says and doesn’t have harmful contaminants. Certifications from well-known organisations like NSF Certified for Sport®, Informed Sport, BSCG, and USP can also show that the product meets good safety and quality standards. Also, brands that are open about where their fish come from are often a good sign. They might use wild-caught fish from clean waters or farmed fish that are raised in carefully controlled conditions. Good quality marine collagen should also be free from unnecessary additives, preservatives, and artificial flavourings, so you’re getting a clean and effective product. Always take a moment to read the product labels carefully for ingredient information and any certifications.   

Thinking About Sustainability: Choosing Products Responsibly:

More and more, we’re all thinking about how sustainable our choices are, and this includes the supplements we use. Traditional collagen production, especially from cows and pigs, can have a big impact on the environment, contributing to greenhouse gas emissions and using a lot of land and water.    

Marine collagen, when sourced in the right way, can be a more environmentally friendly option. It often uses parts of the fish, like skin and scales, that would otherwise be thrown away, which is a good way to reduce waste. However, it’s also important that the fish are caught or farmed responsibly to avoid overfishing and protect our oceans. To make sustainable choices, look for marine collagen supplements that have certifications from organisations like the Aquaculture Stewardship Council (ASC) for responsibly farmed seafood and the Marine Stewardship Council (MSC) for sustainably wild-caught fish. These certifications help ensure that the fish are sourced in a way that’s better for the environment. Brands that really care about sustainability might also use eco-friendly processing methods and recyclable packaging.    

At Oost Nutrition, we know that choosing a marine collagen supplement means thinking about a few things. We’re dedicated to offering a premium product that not only gives you great health benefits but also aligns with your values of quality, safety, and looking after the environment. Our marine collagen is carefully made to meet high standards in all these important areas.

Better Absorption with Our Hydrolysed Formula:

Oost Nutrition’s marine collagen goes through a precise process called hydrolysis, which breaks it down into smaller peptides so your body can absorb it more easily. This means your body can use the collagen effectively to support healthy skin, flexible joints, and your overall well-being, helping you to feel the benefits.
