How much collagen per day?

There is no official recommended daily allowance for collagen. The common dosage in supplements ranges between 2.5 and 15 grams per day, depending on the form and product. Your body produces collagen itself from amino acids, provided there are sufficient building blocks such as vitamin C, zinc, and copper. In this article, you will find an overview of the dosage per supplement form, what research shows, and why you should critically evaluate the claims made by many brands.

Is there a Recommended Daily Allowance (RDA) for collagen?

No. There is no official RDA for collagen, and the Health Council has not established a guideline for daily collagen intake. Collagen is considered a protein that your body produces itself from amino acids under normal circumstances. There is a general guideline for total protein intake: on average between 0.8 and 2 grams per kilogram of body weight per day.

The dosages on collagen supplements are determined by manufacturers themselves, usually based on dosages studied in clinical trials. These are therefore manufacturer recommendations, not official health guidelines.

The absence of an RDA does not mean that collagen as a supplement cannot play a role in your routine. The reasoning of health authorities is mainly that a separate collagen supplement is not necessary when your total protein intake is already adequate.

How much collagen can you take per day?

In recent years, more research has been conducted on collagen supplements. Dosages of 2.5 to 15 grams of hydrolyzed collagen per day have been studied in several studies, usually over a period of 8 to 24 weeks. Dosages above 15 grams per day do not seem to provide a clear additional benefit based on the available data.

However, it is important to know that most studies are relatively small-scale and that individual results vary greatly. There are indications that collagen peptides can play a role in certain bodily processes, but the scientific evidence is not yet strong enough for official collagen claims. Collagen currently has no approved EFSA health claims.

Manufacturers use varying dosages, depending on the type of product. Below is an overview of the common amounts per supplement form:

Which factors influence how much collagen you can take per day?

How much collagen is common per day depends not only on the product you choose. Several personal factors play a role:

• Age: Your body naturally produces collagen, but that production gradually decreases as you age. Whether and how much you want to supplement is individual.
• Nutrition: Your body needs vitamin C, zinc, copper, and sufficient protein to produce collagen itself. A varied diet plays a major role here, and foods containing collagen can be part of that.
• Lifestyle: Factors such as smoking, excessive sun exposure, and a diet rich in refined sugars are associated in research with accelerated collagen breakdown in the body.
• Exercise: People who exercise intensively sometimes use higher dosages as part of their recovery routine. The substantiation for this is still limited.
• Supplement form: Hydrolyzed collagen (collagen peptides) is the most common form and makes it easy to reach 10 to 15 grams per day in powder form. Native collagen is used in much lower dosages (around 40 mg). In terms of source, bovine collagen (mainly type I and III) and marine collagen from fish (mainly type I) are the most common options. For a fish or shellfish allergy, bovine collagen is the logical choice.

Can you take too much collagen?

In principle, no. There is currently no official upper limit established for collagen intake, and dosages up to 10 grams per day are generally well-tolerated in the available literature over periods of up to six months. Even at higher dosages, side effects are rare, although taking too much collagen in combination with products containing many additives can sporadically cause mild digestive complaints.
