Can I Take Too Much Collagen in One Day?
- Collagen is the most prevalent protein in the body, supporting everything from hair and nails to joint and bone health.
- Your body’s collagen production slows down in your 20s, but collagen supplements can help make up any gaps.
- Learning how much collagen to take daily can help ensure you look and feel your best.
Collagen is one of your body’s unsung heroes. This structural protein does it all—and then some. From helping your skin stay healthy to supporting flexibility in your joints, collagen is one of the key pieces to the puzzle to looking and feeling your best.
Collagen supplements can help ensure your body has enough collagen for all these important jobs. But, you’re probably wondering: How much collagen should I take? And when (and how) should I take it? Read on to learn more about supplementing with this powerhouse protein, and get all of your collagen questions answered.
Why should I take collagen?
As the most abundant protein in the body, collagen wears a number of important hats. Want smooth and supple skin? Or, how about healthy hair and nails? Collagen makes that possible. Plus, it’s one of the major building blocks for your bones, tendons, ligaments and connective tissues.
Your body naturally produces collagen. But as you age, both the rate and quality of collagen production slow down. That doesn’t exactly bode well for bone creation and joint health, but not all hope is lost! Your skin may be the first to show signs of aging in the form of wrinkles and fine lines, but taking collagen as part of your skincare routine can help support skin elasticity, skin hydration and overall skin health.
Different types of collagen and their benefits
What are the 5 types of collagen found in our body? Here’s a quick rundown on the differences between them:
- Type 1: This type of collagen is the building block for healthy skin. Because our collagen production decreases with age, using supplements featuring type 1 collagen can be beneficial.
- Type 2: The primary collagen found in cartilage, type 2 supports healthy joints.
- Type 3: Typically found in the same locations as type 1, type 3 collagen is a significant component of our organs and skin.
- Type V: A minor collagen component, it helps regulate the development of collagen fibers of connective tissues.
- Type X: X is another type of collagen that helps bone formation in articular cartilage.
Do you need all 5 types of collagen outlined above? Clinical research shows that taking types 1 and 3 provide the building blocks to support healthy skin, bones, joints and muscles.
The scoop on hydrolyzed collagen
Hydrolyzed collagen, in particular, makes it easy for your body to put this vital protein straight to work. And it has the side benefit of making collagen powder dissolve easily in beverages! Let our in-house expert explain exactly how the process works.
“Hydrolyzed collagen, also known as collagen peptides, describes collagen that has undergone a process called hydrolysis,” says Bulletproof Manager of Science and Nutrition Emily Gonzalez, ND. “This process takes collagen and breaks it down into smaller molecules—amino acids, di- and tri-peptides—so that it may be more easily absorbed and so that it is soluble in cold water. Larger molecules, made up of the same amino acids, are called gelatin and are only soluble in hot water, and will gel in cold water.”
Bulletproof tip: If you’re following a vegan diet or you simply prefer not to eat animal products, you should know that many supplements derive collagen from animal sources. Some marine collagen supplements derive collagen from fish, while other plant-based supplements don’t actually contain any collagen, but can help support your body’s own production of this important protein. Look for phrases like “bovine collagen” or “marine collagen” to help you determine which supplements best fit your diet and lifestyle.

How much collagen should I take?
“There is no official recommended daily dose of collagen, like those for vitamins and minerals,” says Dr. Gonzalez. “However, your body does need the amino acids from collagen, like glycine, proline and hydroxyproline, every single day.”
Glycine is a nonessential amino acid that helps your body produce a key antioxidant called glutathione. 
“Glycine is not present in appreciable amounts in sources of protein that we eat every day,” Dr. Gonzalez says.
That’s why supplementing your diet with collagen products is key. But how exactly should you implement this wellness practice?
The best way to answer the question, “How much collagen should I take per day?” is to talk to your doctor or nutritionist about your goals. Are you trying to better manage your weight? Build muscle mass? Burn fat? The right daily amount of collagen will also vary based on your daily activity levels.
As a general guideline, though, Dr. Gonzalez recommends 10-30 grams of collagen per day.
As for when? There’s no hard-and-fast rule about the best time of the day for taking collagen supplements. Go with what works best for your schedule. Whether that’s adding collagen peptides to your morning coffee or a collagen protein bar as a midday snack (or, let’s be honest, both!), it’s totally up to you!
“Collagen can be taken whenever is most convenient for each person,” Dr. Gonzalez says. “It is not a stimulant, so it will not keep you up in the evening. At night, it can provide replenishing amino acids to support healthy skin, bones and joints. And during the day, at a dose of 10g, it has been found to provide relief from joint pain during and after exercise.”
What happens if I take too much collagen?
If there are so many benefits of collagen, you might be wondering if it’s a good idea to take even more than the recommended dose. But with collagen, as with many dietary supplements, more isn’t always better.
“It is best to stay within the recommended daily protein intake guidelines based on your goals and needs,” Dr. Gonzalez says.
Taking too much collagen (or other proteins) may cause you to feel side effects like indigestion or intestinal discomfort, but it’s not likely to harm you beyond that.
“Collagen is a safe and nontoxic daily supplement that usually doesn’t cause adverse effects,” Dr. Gonzalez says.
