Quick answer

To make collagen coffee, stir 1 scoop of collagen peptide powder into 8 fl oz of hot brewed coffee, which USDA lists at about 95 mg of caffeine. Collagen peptides are cut into small pieces of about 3 to 6 kDa, against about 300 kDa for whole collagen, which is why they dissolve in liquid.1,2

Key facts

  • A 237 g cup (8 fl oz) of brewed coffee holds about 95 mg of caffeine by USDA values. FDA cites 400 mg a day, about two to three 12-ounce cups, as an amount not generally linked to negative effects in most adults.1,3
  • Collagen peptides are small pieces of collagen, about 3 to 6 kDa, which dissolve easily in water. Gelatin is collagen that has not been cut down this way.2,4
  • In a 2025 randomized crossover trial of healthy volunteers, the peptides measured reached the blood at similar levels whether collagen dissolved in coffee or in water. The authors work for a collagen maker.5
  • Most trials of collagen used 2.5 to 15 g a day, so there is little information on 20 g or more a day over months.6,7
  • Fish is one of the nine major food allergens FDA lists, and FDA says food labels must name the source of each one. Collagen comes from cattle, pigs, fish or chicken, so check which one a powder uses.2,8

How to make collagen coffee, hot

Collagen coffee is brewed coffee with collagen peptide powder stirred in. There is nothing to cook. The only choices are how you mix it and how much powder you use, and the second one is printed on the tub.

  • 8 fl oz (237 g) hot brewed coffee1
  • 1 scoop collagen peptide powder, or the serving on your label
  • A splash of milk or a milk alternative, if you take it
  • Put the powder in the empty mug first.
  • Pour in a small amount of the hot coffee and stir into a smooth paste, then pour in the rest.
  • For a mug with no lumps, run a handheld frother in it for 10 seconds.
  • Drink it while it is hot.

The coffee adds about 2 kcal and about 95 mg of caffeine by USDA values, and the powder adds what its panel says.1

Does collagen powder dissolve in hot coffee, and does coffee change it?

Two things decide whether a powder dissolves: how finely the collagen is broken up, and whether it is gelatin. The label words to look for are hydrolyzed collagen or collagen peptides.

Collagen peptides, also sold as hydrolyzed collagen or collagen hydrolysate, are collagen cut by enzymes into small pieces of about 3 to 6 kDa, against about 300 kDa for whole collagen. That makes them dissolve easily in water.2

Gelatin is a non-hydrolyzed form of collagen, not cut down into small peptides. In a direct comparison, glycine from gelatin peaked in the blood later than glycine from collagen peptides.4

The one study we found that tests coffee directly was a randomized crossover trial in healthy volunteers. It gave the same single dose of bovine collagen hydrolysate in coffee on one day and in water on another. The peptides it measured reached the blood at similar levels in both cases, while free hydroxyproline and proline varied over time with coffee. We read the abstract only, and the authors work for a collagen maker.5

How to make collagen coffee creamer at home

A homemade creamer is a scoop of powder frothed into warm milk. A quarter cup (61 g) of whole milk adds about 35 kcal and 1.9 g of protein, and a quarter cup (65 g) of unsweetened almond milk adds about 10 kcal.9,10

  • A quarter cup of milk, oat milk or almond milk, warmed until steaming
  • 1 scoop collagen peptide powder
  • A quarter teaspoon of vanilla extract and a pinch of cinnamon, optional
  • Warm the milk in a small pan or the microwave.
  • Add the powder and vanilla and froth for 15 seconds, or shake in a closed jar.
  • Pour into the coffee. Make it fresh for each cup.

We do not suggest a jar of creamer for the week. A milk-based mix is perishable, and FDA says to refrigerate perishable food within 2 hours and keep the refrigerator at 40°F or below.11

Iced collagen coffee recipe

Powder tends to clump in cold liquid, so it goes into a small amount of room temperature liquid first. With half a cup (122 g) of 2% milk the drink adds about 60 kcal and 4 g of protein on top of the coffee.12

  • 1 cup (237 g) cold coffee, chilled overnight1
  • Half a cup (122 g) 2% milk or a milk alternative12
  • 1 scoop collagen peptide powder
  • A full glass of ice
  • Shake the powder with the milk in a closed jar for 15 seconds.
  • Pour over the ice, then add the cold coffee.
  • Stir once and drink.

Collagen coffee benefits: what this page does not say

This is a recipe page, and recipes do not make claims. Whether collagen does anything is a separate question that depends on the study, the outcome and who paid for it, and the answers differ. Each finding is graded and sourced on our collagen guide.

Putting collagen in coffee is a way to take it. It adds nothing to the case for or against collagen itself, and it is not a reason to expect any particular result.

Collagen coffee powder, pods and where to find them

Collagen coffee appears as a powder you add, as a coffee with collagen already in it, and as pods. We do not list stores or brands, which change, and we have not reviewed any of them. The label is the same in every case.

  • The Supplement Facts panel lists the active ingredients, the amount per serving and the other ingredients. The company chooses the serving size.13
  • Look for the grams of collagen per serving, and whether it says hydrolyzed collagen or peptides, or gelatin.
  • Check the source (bovine, marine, porcine or chicken) against any food you avoid, and read the allergen line. FDA says food labels must name the source of each major allergen.8
  • Look for caffeine. Many packaged drinks and supplements list it, but restaurants and cafes are not required to, and FDA suggests asking.3

Caffeine and collagen: who should check first

FDA advises people who are pregnant, trying to become pregnant or breastfeeding to ask a health care provider whether to limit caffeine, and says certain conditions and some medicines make people more sensitive to it. The Dietary Guidelines say to avoid caffeinated drinks for children under 2, and medical experts advise against energy drinks for children and teens.3

Ask your doctor before using collagen if you are pregnant or nursing, have kidney disease or have had kidney stones, or have been told to limit protein. Ask your pharmacist about timing if you take a medicine that has to be taken on an empty stomach, such as levothyroxine. Its label does not mention collagen, and that is not a finding either way.14,15

Fish collagen is a concern for people allergic to fish, a major food allergen that labels must name. Some people with alpha-gal syndrome, a red meat allergy usually caused by tick bites, also react to gelatin and other products made from mammals.16,17

Collagen is rich in hydroxyproline, which the body partly turns into oxalate. In a feeding study, 30 g of gelatin raised urinary oxalate 43 percent compared with whey, and 5 to 10 g also changed it, which matters for people who form calcium oxalate kidney stones.14

Most trials used 2.5 to 15 g a day, so there is little information on how 20 g or more a day is tolerated over months.6,7

Questions people ask

How do you make collagen coffee?

Put 1 scoop of collagen peptide powder in an empty mug, stir in a little hot coffee to make a paste, then add the rest. A handheld frother clears any lumps.

How do you make a collagen coffee creamer at home?

Warm a quarter cup of milk, froth 1 scoop of collagen peptide powder into it with a little vanilla, and pour it into your coffee. Make it fresh each time, because milk-based mixes are perishable.11

Does coffee change how collagen powder is absorbed?

One randomized crossover trial in healthy volunteers found similar blood levels of the collagen peptides measured whether the dose was dissolved in coffee or in water. We read the abstract only, and the authors work for a collagen maker.5

What are the benefits of collagen coffee?

This recipe page makes no benefit claims. The graded and sourced findings on collagen, including where the evidence is weak, are on our collagen guide.

What should I check on collagen coffee powder or pods?

Check the grams of collagen per serving, the type (hydrolyzed collagen, peptides or gelatin), the source animal, the allergen line and any caffeine. The Supplement Facts panel lists active and other ingredients, and the company sets the serving size.8,13

How much caffeine is in a cup of collagen coffee?

The caffeine comes from the coffee. USDA lists brewed coffee at about 95 mg in an 8 fl oz cup, and FDA cites 400 mg a day as an amount not generally linked to negative effects in most adults.1,3
