Indications

Marine Collagen is a protein supplement made from the skin or scales of fish, usually as hydrolysed collagen (collagen broken down into small pieces called peptides for easier absorption). It is used to support skin hydration and elasticity, to help reduce the look of fine lines, and to support healthy hair, nails, bones and joints. Some studies show modest improvements in skin moisture and elasticity after several weeks, but evidence for other uses is limited.

How It Works

Collagen is the main structural protein in skin, bones, tendons and cartilage. After digestion, collagen peptides and amino acids such as glycine, proline and hydroxyproline are absorbed into the blood. They provide building blocks and may signal skin and joint cells to make more of their own collagen. Vitamin C, often added to these products, is needed by the body to make collagen.

Dosage and Administration

Take as directed on the label, usually once a day. Powders are mixed into water, juice or another drink; tablets or capsules are swallowed with water. It can be taken with or without food. Use regularly for at least 8 to 12 weeks to judge the effect.

Interactions

• No important drug interactions are well known.
• If the product contains added calcium, keep it at least 2 hours apart from Levothyroxine and antibiotics such as Ciprofloxacin or Doxycycline.
• Check the label for added vitamins or herbs that may interact with your medicines.

Contraindications

• Allergy to fish or shellfish.
• Allergy to any other ingredient.

Side Effects

It is usually well tolerated. Some people notice a fishy taste or aftertaste, a feeling of fullness, heartburn, mild stomach upset or loose stools.

Get urgent medical help if you have signs of a serious allergic reaction, such as hives, swelling of the face, lips or throat, wheezing or difficulty breathing.

Pregnancy and Lactation

Collagen is a food protein, but the safety of concentrated supplements in pregnancy and breastfeeding has not been well studied. Ask your doctor before use.

Precautions and Warnings

• People with kidney disease or on a protein-restricted diet should ask their doctor first, as it adds protein to the diet.
• Choose products from trusted makers that are tested for heavy metals.
• It does not replace sun protection, a balanced diet or treatment for skin, hair or joint disease.

Overdose

Overdose is unlikely to be serious. Large amounts may cause fullness, stomach upset or loose stools. Seek advice if symptoms are severe.
