Which collagen is right for you?
Every pick here is a collagen peptide powder. One scoop a day is enough for most people (how much to take). Want collagen from grass-fed cows? See the best grass-fed bovine collagen.
Don’t eat beef? Get collagen from fish.
Codeage Marine Collagen is made from wild-caught fish and is on NSF/ANSI 173, which checks the amount and heavy metals. At 10 g a day it costs about $20 a month more than our pick. More fish options: best marine collagen.

Taking collagen pills? You’re probably getting too little.
We read 465 collagen labels from the NIH label database. The typical capsule label directs 1.8 g a day, and about 7 in 10 capsule labels direct less than 2.5 g, the smallest dose trials used. The typical powder directs 11 g. A scoop of powder in your coffee is the easy fix. If you want a chew, see collagen gummies.
Want collagen with vitamins mixed in?
Beauty blends like Garden of Life Collagen Beauty add biotin and vitamin C. Those vitamins cost little on their own, so a plain powder plus a multivitamin you already take does the same job. Want hyaluronic acid in the scoop? See collagen with hyaluronic acid.

Buy plain collagen peptides
Look for “hydrolyzed collagen” or “collagen peptides” on the label. That is the form almost every trial used, and it dissolves in hot or cold drinks. Most powders, from cows or fish, are types I and III, the kinds in skin. Type II for joints (often sold as UC-II) is a different, low-dose product (types compared).
Does collagen work?
For skin, the results are mixed. A 2023 review found that collagen improved skin hydration and elasticity (Pu 2023), and in one trial 2.5 g a day for 8 weeks was enough (Proksch 2014). But a 2025 review of 23 trials found those gains only in trials paid for by companies, and none in the best-run ones (Myung 2025). For joints, a 2019 review found it eased osteoarthritis pain, but joints have been studied less than skin (García-Coronado 2019). Collagen is safe for most people; skip fish collagen if you have a fish allergy. If skin aging is your reason, daily sunscreen has stronger evidence: in a 4.5-year trial, people who used it every day showed less skin aging (Hughes 2013). A broad-spectrum pick: EltaMD UV Clear SPF 46.
Questions people ask
What is the best collagen supplement?
For most people, BulkSupplements Bovine Collagen: 11 g of plain collagen peptides a serving for $0.56 per 10 g, on NSF Certified for Sport.
How much collagen should I take a day?
Trials used 2.5 to 15 g a day. Skin studies often used 2.5 to 5 g; joint studies used up to 10 g. One scoop of most powders covers it. How much collagen to take.
Does collagen count as protein?
Not as a full protein. Collagen has no tryptophan, one of the amino acids your body needs from food, so it does not replace a protein powder for building muscle.
How long does collagen take to work?
Most skin trials measured changes after 8 to 12 weeks of daily use. Take it every day; the time of day does not matter.
How we score
Five marks: does a serving hold a studied dose; is the product on a public testing list (a brand’s own testing claim, with no listing, earns half the points); what a dose costs at the brand’s own price against the cheapest; does the label state the amount with no blend; and the brand’s FDA recall record. Dose and testing are worth up to 3 points each, cost up to 2, label and recalls up to 1 each, for 10 in all. The costs on this page are each brand’s own price; Amazon’s can differ.
