Buying a Collagen Supplement? 7 Things You Need to Look For

Mention collagen 10 years ago and very few people would know what you're talking about.

If you want to learn more, please visit our website SEMNL.

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

Marine collagen dangers - Fitness World Nutrition

Marine collagen has become a highly sought-after dietary supplement , particularly in the field of sports nutrition. Appreciated for its benefits on the health of the skin , joints and connective tissues , it appeals to many fitness and bodybuilding enthusiasts.

However, despite its success, it is essential to consider the potential dangers associated with its consumption. Here, we will analyze the risks associated with taking marine collagen and the precautions you need to take for safe use.

What is marine collagen?

Marine collagen is a protein extracted from the skin, scales or bones of fish such as salmon, pollock and tilapia. It is usually hydrolyzed to make it easier for the body to absorb.

Its similar structure to human collagen makes it an effective supplement to support the health of connective tissues, including the skin and joints.

The potential risks of marine collagen

Fish allergies

One of the main concerns about consuming marine collagen is the risk of allergies. People who are allergic to fish may develop allergic reactions when consuming this type of collagen. Symptoms may include itching, rashes, swelling, or even difficulty breathing. It is essential for anyone with a seafood allergy to consult a healthcare professional before considering taking marine collagen .

Keep in mind that even without a known allergy, some people may develop a sensitivity or intolerance to marine collagen, manifested by digestive disorders such as nausea, bloating, or diarrhea. We recommend starting with a small dose and observing how your body reacts before increasing the amount consumed.

Heavy metal contamination

Heavy metal contamination, such as mercury, lead, or arsenic, is another major concern. These metals can accumulate in fish tissues due to water pollution. If collagen is extracted from fish from polluted areas, it may contain dangerous levels of these substances. Regular consumption of contaminated marine collagen can have long-term adverse health effects, including damage to the nervous system, liver, and kidneys. To minimize this risk, it is important to choose products that come from reliable sources and are tested for purity.

It is important to note that European regulations impose strict limits on the levels of heavy metals in dietary supplements. However, not all products always meet these standards, making it essential to check for quality certifications when purchasing marine collagen.

Drug interactions

Marine collagen may interact with some medications, particularly blood thinners. Collagen contains amino acids that can potentially increase blood clotting, which could interfere with medications intended to reduce the risk of blood clots. People taking medications, particularly for cardiovascular conditions, should consult their doctor before incorporating marine collagen into their routine.

In addition to blood thinners, marine collagen may interact with other medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) and some blood pressure medications. It is therefore essential to discuss with a healthcare professional to avoid any unwanted interactions.

Risks of overdose

Although marine collagen is generally well tolerated, excessive consumption can lead to unwanted side effects. An overdose of protein, including collagen, can overload the kidneys, especially in people with already compromised kidney function. Additionally, excess collagen can cause digestive upsets such as bloating, constipation, or diarrhea.

Another risk associated with overdose is hypercalcemia, a condition where calcium levels in the blood are too high. Although rare, this condition can occur if marine collagen is consumed in large amounts over a long period of time, especially if calcium supplements are also taken. Symptoms of hypercalcemia include nausea, vomiting, muscle weakness, and mental confusion.

Precautions to take

Choosing a quality product

The quality of the health food supplement "Marine Collagen" depends largely on the source of the fish and the manufacturing methods used. Opt for products from recognized brands that carry out rigorous testing of their raw materials. Make sure that the collagen comes from wild or sustainably farmed fish and that it is free of contaminants.

Also look for certifications like the Marine Stewardship Council (MSC) label, which ensures that the collagen is sourced sustainably and environmentally friendly. Products with the Good Manufacturing Practices (GMP) label are also recommended, as they indicate that the manufacturer follows strict manufacturing practices to ensure product quality and safety.

Consult a health professional

Before you start taking marine collagen, we advise you to consult a healthcare professional , especially if you have a medical history, are taking medications or are prone to food allergies. A medical opinion will help you determine if marine collagen is suitable for your situation and what dose would be most appropriate.

Pregnant or breastfeeding women should especially consult their doctor before taking marine collagen supplements, as the safety of this supplement during pregnancy is not fully established.

Follow dosage recommendations

Respecting the doses recommended by the manufacturer is essential to avoid side effects related to excessive consumption. Generally, a daily dose of 2.5 to 10 grams of marine collagen is considered safe and effective.

If adverse symptoms occur, reduce the dose or stop taking the supplement and consult your doctor.

Marine collagen is a great ally to support the health of your skin, joints and connective tissues. However, as with any dietary supplement , it is important to be aware of its potential risks and take all necessary precautions to ensure safe use.

By choosing a quality product, respecting the recommended doses and consulting a health professional , you can enjoy the benefits of marine collagen with peace of mind.
