The Science Behind Hydrolyzed Bovine Collagen (Types 1 and 3)

What collagen and vitamin C do in the body. Collagen is the most abundant protein in the body and the primary structural protein of skin and connective tissue. Type 1 collagen is concentrated in skin, bone, and tendons, and type 3 is found alongside it in skin and connective tissue. Vitamin C is a required cofactor for the enzymes that stabilize the structure of collagen the body makes, which is why the two are often paired.

Collagen peptides and skin in a controlled trial. This product was not studied directly. In a double-blind, placebo-controlled trial published in Skin Pharmacology and Physiology (Proksch et al., 2014), 69 healthy women ages 35 to 55 took 2.5 g or 5 g of a specific collagen peptide daily, or a placebo, for eight weeks. Both doses improved skin elasticity compared with placebo, with no significant difference between the two doses, while skin hydration did not differ significantly from placebo. The study used a branded porcine type I collagen peptide in powder form, not this formula.*

What the broader research shows. This product was not studied directly. A systematic review and meta-analysis published in Nutrients (Pu et al., 2023) pooled 26 randomized controlled trials with 1,721 participants. Hydrolyzed collagen supplementation improved skin hydration and elasticity compared with placebo across studies lasting 2 to 12 weeks. The authors noted differences between trials in collagen source, dose, and measurement, and called for larger trials to confirm the findings. Most included trials used fish collagen, and only one used bovine collagen.*

Frequently Asked Questions

What is liquid collagen good for?

Liquid collagen supports skin health, joint health, and connective tissue as part of a consistent daily routine.* Double Wood Liquid Collagen provides 2500 mg of hydrolyzed bovine collagen, types 1 and 3, in each 15 mL serving, plus 90 mg of vitamin C and 30 mcg of biotin, in a ready-to-take liquid.

How much liquid collagen should I take per day, and when?

Take 1 serving (15 mL, about 1 tablespoon) per day, with or without food, as directed on the label. There is no required time of day, so most people take it with a morning routine. Each bottle provides 32 servings.

What does it taste like?

Double Wood Liquid Collagen has a natural pear flavor sweetened with stevia leaf extract. Taste is personal. If you prefer it milder, stir your serving into water, juice, sparkling water, or a smoothie instead of taking it straight.

Is liquid collagen better than powder?

Both provide hydrolyzed collagen peptides, so the right choice comes down to your routine. Liquid Collagen is ready to take in one spoonful and includes vitamin C and biotin. Collagen Peptides powder provides a larger 12 g serving that you stir into a drink. Most people choose one format rather than taking both.

What supplements pair well with liquid collagen?

Astaxanthin pairs with Liquid Collagen as part of a daily skin wellness routine. Collagen supports skin and connective tissue, while Astaxanthin supports antioxidant activity and skin wellness.* Take Astaxanthin with food, ideally a meal containing fat, and take Liquid Collagen according to its own label. Both fit easily into a morning routine.

Are there side effects of liquid collagen?

Many adults tolerate collagen peptides well when used as directed, though individual responses vary. Discontinue use if you experience any adverse reaction. The formula is sweetened with stevia leaf extract, so review the ingredient list if you have a sensitivity to stevia. Consult your physician before use, and do not use if you are pregnant, nursing, or under 18 years of age.

Is Double Wood Liquid Collagen third-party tested?

Yes. Every batch tested. Third-party tests by ISO/IEC 17025 accredited labs. COAs published openly.
