❓Frequently Asked Questions
For skin, the evidence is promising: a 2019 systematic review of 11 randomized trials found better skin elasticity and hydration with 2.5–10 g of hydrolyzed collagen peptides a day for 4–24 weeks. Many of those trials were funded by manufacturers, so treat the size of the effect with caution. Joint studies at about 10 g a day are smaller and mixed.
Type I and III bovine collagen (from grass-fed hide) is best for skin, hair, nails, and gut health. Type II collagen (from chicken sternum, ideally undenatured/UC-II) is specifically for joints and cartilage. Marine collagen is also Type I and has slightly better bioavailability but costs more. Most "collagen peptides" products are Type I/III bovine.
Currently, no vegan collagen exists — all products are animal-derived (bovine, marine, or porcine). "Vegan collagen boosters" containing vitamin C, zinc, and proline are not collagen; they support your body's own collagen synthesis but cannot replace the peptides directly. Bioengineered vegan collagen is in development but not commercially available.
Take collagen on an empty stomach or 30–60 minutes before exercise for best absorption. Many users prefer morning (in coffee or smoothie). For joint recovery, take 15 minutes before your workout with a small amount of vitamin C — this timing was shown in a Stanford study to maximize collagen synthesis in connective tissue.
Studies consistently use 2.5–10g daily. For skin benefits, 2.5–5g is effective. For joints and athletic recovery, 10–15g is the clinical dose. There's no upper limit established, but most people don't benefit from more than 20g/day. Consistent daily use matters more than the exact dose.
