If you want collagen without sugar, stevia or artificial sweeteners, start with the full ingredient list. A single-ingredient unflavored powder is the easiest label to compare. "Unflavored" does not guarantee no taste, no additives or the same formula across all sizes.

Choose an animal source that fits your allergy and dietary needs. A plain formula avoids some added ingredients but is not automatically suitable for everyone.

## Plain powder options

## Unflavored, unsweetened and sugar-free are different

What the label words do and do not tell you

| Label word | What to verify |
| --- | --- |
| Unflavored | No added flavoring is the aim; the protein can still have a taste. |
| Unsweetened | Check for sweeteners and every other added ingredient. |
| Sugar-free | Stevia, sucralose or other sweeteners may still be present. |
| Single ingredient | Check that the current panel lists collagen only. |
| Collagen blend | Check collagen grams separately from the blend or scoop weight. |

## A short label checklist

- Read both the Supplement Facts and the other-ingredient list.
- Look for stevia, monk fruit, sucralose, acesulfame potassium and sugar alcohols if avoiding sweeteners is your goal.
- Check creamers, flavors, vitamins and other additions rather than assuming all unflavored products are plain.
- Confirm collagen grams per full serving and servings per container.
- Match the product name and package size to the listing you order.

A claim of "no artificial sweeteners" does not answer whether stevia or monk fruit is present. Check for those too if you want no added sweetener.

These are purchasing checks, not a claim that every sweetener is harmful. Preference, tolerance and simplicity can be valid reasons to choose a different formula.

## Which option fits your routine?

The plain bovine Vital Proteins powder and its Marine Collagen provide two different animal-source options. The marine option does not fit a fish allergy, while the bovine option does not fit someone avoiding cattle-derived products. Neither is vegan.

The selected 7.8 oz marine label inspected October 10, 2026 identifies cod and a three-tablespoon (12 g) serving. An undated manufacturer chart uses whitefish and two scoops instead. Use your exact tub's ingredient list, allergen statement and serving instructions rather than combining records.

The [Sports Research unflavored review](https://supplementexplained.com/products/sports-research-collagen-peptides-unflavored/) is another product comparison, not an identical replacement for either Vital Proteins tub. Use its current label and retailer availability rather than transferring another product's serving size.

For the source decision, read [marine versus bovine collagen](https://supplementexplained.com/compare/marine-vs-bovine-collagen/). For Advanced formulas with extras, compare [Advanced versus Original](https://supplementexplained.com/compare/vital-proteins-collagen-peptides-advanced-vs-original/).

## Will an unflavored powder taste neutral?

Unflavored collagen can still change the taste or texture of a drink. The carrier matters: coffee, soup and a smoothie can mask a protein taste differently from plain water. We have not taste-tested these products, so we cannot promise that either is undetectable.

Follow the package mixing directions. If tolerance is your concern, record the exact formula and serving used rather than blaming collagen source alone. Added ingredients, other foods and the rest of the routine may matter; persistent symptoms deserve medical advice.

## Compare powder, capsules and gummies fairly

Calculate cost per gram of labeled collagen, including delivery costs. A capsule or gummy can be easier to use, but the amount of collagen per full serving may differ substantially. A low bottle price is not enough to establish good value.

For example, a hypothetical $24 bottle providing 120 g collagen costs $0.20/g. A $36 tub providing 360 g costs $0.10/g. That is a value calculation, not proof that the larger collagen amount is needed or will work better. Our [gummy, capsule and powder comparison](https://supplementexplained.com/compare/vital-proteins-collagen-gummies-vs-powder-vs-capsules/) separates those formats.

## What a simpler formula cannot promise

Removing sweeteners or extras makes a label easier to understand; it does not solve the uncertainty in collagen research. The 2025 meta-analysis reported positive pooled skin results, but its higher-quality and non-industry-funded subgroups did not show statistically significant benefits. Do not read "cleaner" packaging as evidence of better clinical outcomes.

Before paying more for testing language, check the [collagen testing map](https://supplementexplained.com/quality/collagen-heavy-metals-testing-map/). Keep basic skin care, sufficient food protein and the actual reason for buying in view.
