Marine collagen: What are the possible side effects?

Collagen is a protein that is naturally present in our body. It plays an essential structural role. As we age, our production of collagen tends to decline. It may therefore be worth taking a collagen supplement from the age of 25.

We have already seen the key role played by collagen in the appearance of our skin, nails and hair, as well as its essential role in joint suppleness and sports recovery. To compensate for the decline in our collagen stocks with age, taking collagen is increasingly appearing as an attractive anti-ageing solution. No food supplement can prevent the normal ageing process, but consuming properly measured doses of collagen, alongside a healthy lifestyle, will help to slow the effects of ageing in terms of your skin's appearance and, more especially, help the skin to age well.

Recognised as one of the best collagens for supplement use, marine collagen is highly concentrated in the amino acids proline, glycine and hydroxyproline. It is reputed to plump, firm and smooth the skin, while reducing the appearance of deep wrinkles. Ideal as an anti-ageing active ingredient, it delays the appearance of wrinkles, reduces skin ageing and improves skin elasticity.

Marine collagen supplements also supports athletes by improving their post-workout recovery. Very high in protein, marine collagen helps to improve and develop muscle mass in conjunction with appropriate sports training. Taking collagen also promotes muscle and joint comfort after exercise, as well as good muscle oxygenation.

Finally, studies also suggest that collagen supplements could have a positive impact on cardiovascular health by helping to reduce hypertension. Preliminary research has shown that collagen may help to maintain healthy blood vessels by promoting elasticity and regulating blood pressure. So, in addition to its benefits for muscle recovery, taking marine collagen could potentially contribute to the overall health of the cardiovascular system.

Marine collagen is available in powder form, such as Aroma-Zone marine collagen powder, or in capsule form.

Generally speaking, there are few contraindications to collagen supplementation, and marine collagen in particular. If there is an excess of collagen, the body eliminates the surplus.

The main risks of marine collagen supplements could come from the quality and origin of the supplement chosen. Always carefully check the origin of the collagen in your product. Always opt for collagen supplements that give you maximum guarantees of sustainable, ethical and eco-friendly production methods. If it's marine collagen, you can avoid a high concentration of heavy metals by choosing collagen from sustainable and responsible aquaculture.

However, as with any food supplement, it is essential to follow the recommended quantities to avoid any risk of overdosing, and to guarantee the quality and traceability of your collagen, in compliance with European regulations. You should also remember that only adults in good health should use food supplements. If you have any kind of health condition, you should always consult your doctor before taking any supplements.

Let's now look at the main questions that often arise about the collagen consumption.

Collagen is not fattening. The protein intake generated by collagen peptide supplementation is beneficial to muscle mass gain at the expense of fat mass, as part of regular, moderate to intense sports activities. As part of a healthy lifestyle, with a balanced diet and regular exercise, marine collagen can promote lean muscle mass and help you maintain a healthy weight.

The proteins contained in collagen can also help you feel full and prevent cravings.

Taking collagen peptides will not harm the liver if the recommended daily doses are respected (maximum 2.5 to 10 g per day). Often, when people talk about the danger to the liver from collagen consumption, it's due to an excessive concentration of heavy metals. In fact, some fish can have high concentrations of heavy metals caused by human pollution of the oceans. Always check the manufacturer's information on this subject. As far as regards Aroma-Zone marine collagen powder, we have chosen premium quality collagen peptides from fish skins raised in responsible and sustainable Friend of the Sea certified aquaculture. Each batch is checked for compliance, particularly with regard to heavy metals.

If you are allergic to seafood, you are not advised to take marine collagen supplements.

If you feel unwell, itchy or have difficulty breathing, this may be an allergic reaction. Contact emergency services immediately and stop taking the supplement.

Rare cases of bloating, constipation, gastric acidity or diarrhoea have been reported, but these are very rare. If you notice any undesirable effects when taking collagen as a powder or in capsules, stop taking the supplement and talk to your health professional.
