Vital Proteins Original Collagen Peptides is an unflavored powder with one listed ingredient: bovine collagen peptides. The 19.3 oz and 9.33 oz canisters sold by Vital Proteins both list a 20 g serving, but the larger canister costs less per serving. This review is based on manufacturer labels and prices.
Quick verdict. The 19.3 oz canister offers the better value of the two at about $1.61 per labeled serving. The 9.33 oz canister costs $27 upfront and comes to about $1.93 per labeled serving. The smaller size makes sense if you want to try the powder with a lower upfront spend. 19.3 oz product page · 9.33 oz product page

Serving size and mixing directions
Both canister labels list four tablespoons as a 20 g serving. The 19.3 oz directions specify four level tablespoons mixed thoroughly into 8 fluid ounces of liquid. If you prefer a kitchen scale, use the 20 g serving on the label. When a retailer shows scoops or packets, compare the gram amount printed on that specific package. 19.3 oz directions · 9.33 oz label
Price and cost per serving
These were the one-time prices on Vital Proteins’ US site on November 4, 2026. The figures exclude taxes, shipping, subscription discounts, and promotions.
| Canister | One-time price | Labeled servings | Cost per serving |
|---|---|---|---|
| 9.33 oz | $27.00 | About 14 | $1.93 |
| 19.3 oz | $45.00 | About 28 | $1.61 |
The larger canister costs $18 more upfront and gives you about twice as many labeled servings. It saves roughly $0.32 per serving. Both canisters use a 20 g serving, so cost per serving works well for this comparison. If another brand uses a different serving size, divide the price by the package’s net weight in grams to compare plain powders on the same basis.

What the collagen research tells us
A 2025 review of randomized trials found that results for skin hydration, elasticity, and wrinkles varied by funding source and study quality. The review found no significant improvement in those outcomes when it looked at the higher-quality trials as a group. That review covered collagen supplements as a category. The buying verdict here is based on this product’s label and price. 2025 systematic review in The American Journal of Medicine
Bottom line
If you want a single-ingredient bovine collagen powder and expect to finish the canister, the 19.3 oz Original Unflavored offers the better value at the prices checked. The 9.33 oz version offers the same labeled serving with a lower upfront price. For retailer listings, confirm that the title says Unflavored, then check the package weight and Supplement Facts before comparing prices. Vital Proteins Original Collagen Peptides
