Is Chief or The Collagen Co collagen better?

Both are hydrolysed grass-fed bovine collagen at a 15g serve, so the collagen is comparable. Chief keeps its tub pure, 100% collagen, third-party tested for heavy metals, pesticides and glyphosate, with monk fruit in the flavoured tubs. The Collagen Co adds Vitamin C, Hyaluronic Acid and Biotin, with a wider flavour range, and its flavoured tubs use erythritol. Chief is also cheaper per serve. Choose on a pure tested formula against the added actives and flavours.

Which one is cheaper?

Chief. A serve is about $1.77 against The Collagen Co's about $2.82, and per 100 grams it is about $11.80 against about $18.80. Chief's 450g tub is $52.95 and The Collagen Co's 420g is $79.00.

What is the difference in what is in the tub?

Chief's unflavoured is 100% collagen and nothing else. The Collagen Co's unflavoured is a formula that also contains Vitamin C, Hyaluronic Acid and Biotin. So Chief is pure collagen, and The Collagen Co is a collagen and beauty-actives blend.

Which one is tested for heavy metals?

Chief states on its page that its collagen is third-party tested for heavy metals, pesticides and glyphosate. The Collagen Co's product page does not publish that testing. Both may test internally, but only Chief shows it, which matters for an animal-sourced powder.

Do either use sugar alcohols?

The Collagen Co's flavoured tubs use erythritol, a sugar alcohol that some people find hard on the gut. Chief's flavoured tubs use monk fruit and no sugar alcohols. Both unflavoured tubs are free of sweeteners.

Is collagen a complete protein?

No, for either brand. Collagen is rich in glycine and proline for skin and connective tissue, but it is low in some essential amino acids. So it is not a one-to-one replacement for a complete protein like whey when you are building muscle.

No. Both are bovine collagen, so neither suits vegans or vegetarians. Vegan collagen products supply nutrients that support your own collagen, but they are not collagen itself.

Chief vs The Collagen Co Collagen: An Honest Comparison

The real difference is what is in the tub. Chief is pure 100% grass-fed bovine collagen, third-party tested for heavy metals, pesticides and glyphosate, and flavoured with monk fruit rather than a sugar alcohol. The Collagen Co blends in Vitamin C, Hyaluronic Acid and Biotin and carries a wider flavour range, and its flavoured tubs use erythritol, a sugar alcohol. Chief is also cheaper per serve, about $1.77 against about $2.82. Pick a pure tested collagen against added actives and more flavours.

At a glance

Start with what is in the tub, because that is where these two really differ. Both are hydrolysed grass-fed bovine collagen at a 15g serve from an Australian brand, so the collagen itself is comparable. Chief keeps it pure: its unflavoured tub is 100% collagen and nothing else, third-party tested for heavy metals, pesticides and glyphosate, with the results on the page, and its flavoured tubs use monk fruit rather than a sugar alcohol. The Collagen Co builds more into the tub, adding Vitamin C, Hyaluronic Acid and Biotin, with a much wider flavour range, though its flavoured tubs use erythritol, a sugar alcohol. Chief is also cheaper, about $1.77 a serve against The Collagen Co's about $2.82, which follows from keeping the tub to one ingredient. Choose Chief for pure, tested collagen with monk fruit and a lower price; choose The Collagen Co for the added actives and the wider flavour range.

The cost, in full

All prices are AUD, read from each brand's own site on 6 July 2026. Both use a 15g serve, so the comparison is clean. Chief's 450g tub is $52.95, about $1.77 a serve, or about $11.80 a 100 grams. The Collagen Co's 420g tub is $79.00, about $2.82 a serve, or about $18.80 a 100 grams. Chief is clearly cheaper for the same grass-fed bovine collagen.

Part of the price gap is the added actives. The Collagen Co builds Vitamin C, Hyaluronic Acid and Biotin into the tub, so you are paying for a formula, not just collagen. Chief keeps it pure and cheaper, and leaves the extras to you. Which is better value depends on whether you want those actives in the same scoop.

Where Chief is the better choice

You want pure collagen and no sugar alcohols

Chief's unflavoured collagen is 100% collagen and nothing else: no added vitamins, no sweeteners, no sugar alcohols. The Collagen Co's unflavoured is a formula that also carries Vitamin C, Hyaluronic Acid and Biotin, and its flavoured tubs are sweetened with erythritol, a sugar alcohol. Chief flavours with monk fruit instead. For anyone who wants just the collagen, or who reacts to sugar alcohols, that is the plainer tub.

You want published contaminant testing

Chief has its collagen third-party tested for heavy metals, pesticides and glyphosate, and states it on the product page. The Collagen Co's product page does not publish heavy-metal, pesticide or glyphosate testing. Both may test internally, but only one shows it, and for an animal-sourced powder that is a real point of confidence. Chief puts the results in front of you.

You want the lower price

Serve for serve Chief costs less for the same kind of collagen: about $1.77 against The Collagen Co's about $2.82, or about $11.80 a 100 grams against about $18.80. Both are grass-fed bovine collagen at a 15g serve, so the gap is a genuine saving on a like-for-like ingredient, not a difference in what lands in the tub.

Where The Collagen Co. is the better choice

You want the added actives

The Collagen Co builds more into the tub. Its unflavoured collagen also carries Vitamin C, which supports your own collagen formation, along with Hyaluronic Acid and Biotin, two ingredients often paired with collagen for skin and hair. Chief's unflavoured is pure collagen, so you would add your own vitamin C. For a beauty formula in a single scoop, The Collagen Co has the edge.

You want more flavours

The Collagen Co is built around flavour, and its wide flavoured range is a big part of why people choose it. Chief keeps things simple with three: unflavoured, dark chocolate and creamy vanilla. For anyone who likes to rotate flavours, The Collagen Co has far more to pick from.

You want an established beauty-collagen brand

The Collagen Co is a well-known Australian beauty-collagen brand with a large following and a polished product experience. For the track record and the flavoured-collagen ritual, it delivers on both. Chief comes at collagen from a whole-food angle, as one clean product in a wider range, which is a different sort of appeal.

Pure collagen or a beauty formula

This is the real choice between the two. Chief's unflavoured is 100% collagen, tested for heavy metals, pesticides and glyphosate, with no sweeteners or sugar alcohols. The Collagen Co's unflavoured is a beauty formula, collagen plus Vitamin C, Hyaluronic Acid and Biotin, in a much wider range of flavours, though its flavoured tubs use erythritol. Neither is wrong. One is a clean, tested, single ingredient, the other is a flavoured formula with extras. Match the one that fits how you want to take collagen.

Before you buy

Collagen does not suit everyone. It is not a complete protein, so it should not be your only protein source if you train and need muscle repair. It is bovine, so neither product suits vegans or vegetarians. If you react to sugar alcohols, note that The Collagen Co's flavoured tubs use erythritol, while Chief's flavoured tubs use monk fruit. If you are pregnant, breastfeeding or managing a health condition, check with your healthcare provider before adding a new supplement.
