In France, the demand for collagen-based products has seen a significant surge. By the end of 2023, sales have increased by over 92%, according to Pharmastat. Collagen, an essential protein for skin, joints, and bones, is becoming increasingly popular in supplement form, attracting many consumers with claims of improved firmness, elasticity, and reduced signs of aging. What are the potential risks associated with its consumption?
Collagen is a vital protein in our bodies, found in tissues such as skin, tendons, bones, and cartilage, and is naturally produced by the body. However, its production declines with age, leading to wrinkles, loss of skin firmness, and joint discomfort.
To combat this decline, many people turn to collagen supplements, often accompanied by vitamin C to enhance their effectiveness. Nonetheless, caution is warranted as there are health risks involved.
Collagen Supplements: What Are The Side Effects?
Typically, collagen is well-tolerated, but it can sometimes cause side effects:
- Digestive Issues: Some individuals may experience bloating, diarrhea, or constipation at the beginning of supplementation. These effects are often temporary and arise due to the increase in amino acids.
- Possible Contaminants: The quality of collagen can vary based on its source and production methods. Certain products, especially those derived from marine collagen, may contain heavy metals from fish caught in polluted waters, posing health risks.
- Allergic Reactions: Individuals allergic to fish, shellfish, or other animal products should steer clear of specific collagen types (marine, bovine), as they may trigger itching, skin rashes, or serious reactions.
- Contraindications: Collagen may not be suitable for everyone. Individuals with kidney insufficiencies or hypercalcemia should consult a doctor before taking supplements.
Collagen Supplements: What Precautions Should You Take?
To reduce the risks associated with collagen supplementation, it is crucial to adhere to certain recommendations:
- Select Quality Products: Choose certified supplements that meet established standards and prefer brands transparent about the origin and manufacturing of their collagen.
- Adhere To Dosages: While overdosing is uncommon, do not exceed the recommended dosage (often around 10g/day). The body eliminates excess, but too much collagen can amplify undesirable effects.
- Consult A Healthcare Professional: Before starting a regimen, especially if you have specific medical conditions (pregnancy, breastfeeding, ongoing treatments), seek guidance from your general practitioner.
IMPORTANT TO NOTE
Contrary to common belief, collagen does not contribute to weight gain. In fact, it may assist in maintaining muscle mass and promoting a feeling of fullness.
