Is Chief or True Protein collagen better?

Both are hydrolysed grass-fed bovine collagen, type I and III, so the collagen is comparable. Chief keeps its tub pure, 100% collagen, and third-party tested for heavy metals, pesticides and glyphosate, and it is cheaper per gram. True Protein adds Vitamin C, has more flavours, offers a HASTA-certified collagen and a smaller 10g serve that is cheaper per serve. Choose on a pure tested collagen against the added Vitamin C and options.

Which one is cheaper?

It depends how you measure it. Per gram of collagen, Chief is cheaper, about $11.80 a 100 grams against True Protein's $16. Per serve, True Protein is a little cheaper because its serve is a smaller 10g, at about $1.60 against Chief's $1.77. Per gram is the fairer comparison, and Chief wins it.

What is the difference in what is in the tub?

Chief's is 100% collagen, nothing else. True Protein's is collagen fortified with Vitamin C. So Chief is pure collagen, and True Protein is a collagen and Vitamin C formula. If you want the Vitamin C included, True Protein has it; if you want just collagen, Chief does.

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. True Protein's standard collagen page does not show that testing, though True Protein does sell a separate HASTA-certified collagen, which is tested against banned substances rather than heavy metals. They are different kinds of testing.

Does either have a banned-substance certified option?

True Protein does, with a separate HASTA-certified collagen for drug-tested athletes. Chief does not hold HASTA on any product. If you compete under testing, look at the HASTA collagen or another certified option.

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 True Protein Collagen: An Honest Comparison

Both are grass-fed bovine collagen type I and III, so the collagen is comparable. Chief keeps its tub pure and tested for heavy metals, pesticides and glyphosate, and works out cheaper per gram, about $11.80 a 100 grams against $16. True Protein adds Vitamin C, has more flavours, offers a HASTA-certified collagen for drug-tested athletes and a smaller 10g serve that is cheaper per serve. Pick a pure tested collagen against added Vitamin C and more options.

At a glance

Start with what is in the tub, because that is where these two differ. Both are hydrolysed grass-fed bovine collagen, type I and III, from an Australian brand, so the collagen itself is comparable. Chief keeps its tub to 100% collagen, third-party tested for heavy metals, pesticides and glyphosate, with the results on the page. True Protein fortifies its collagen with Vitamin C to help collagen synthesis, has more flavours and offers a separate HASTA-certified collagen for athletes who are drug tested. On price it depends how you weigh it: Chief is cheaper per gram, about $11.80 a 100 grams against True Protein's $16, while True Protein's smaller 10g serve is cheaper per serve. Choose Chief for pure, tested collagen that is cheaper per gram; choose True Protein for Vitamin C built in, more flavours, a HASTA option or a cheaper per-serve dose.

The cost, in full

All prices are AUD, read from each brand's own site on 6 July 2026. The serve sizes differ, Chief at 15g and True Protein at 10g, so the fair comparison is per 100 grams of collagen. Chief's 450g tub is $52.95, about $11.80 a 100 grams. True Protein's 300g is $48.00, about $16.00 a 100 grams. Chief is cheaper per gram of collagen.

Per serve it looks closer, because True Protein's serve is smaller. Its 10g serve is about $1.60, a little under Chief's $1.77 for 15g, but you are getting a third less collagen in that serve. Some of True Protein's price also covers the added Vitamin C. Weigh it on the collagen you actually get, and Chief is the better value per gram.

Where Chief is the better choice

You want pure collagen and published testing

Chief's collagen is 100% collagen, nothing added, and third-party tested for heavy metals, pesticides and glyphosate, stated on the page. True Protein's collagen is fortified with Vitamin C, so it is a formula rather than pure collagen, and its standard collagen page does not show heavy-metal, pesticide or glyphosate testing. For anyone who wants just the collagen and wants to see the contaminant testing, Chief is the plainer, more open choice.

You want Australian grass-fed sourcing and a bigger serve

Chief's collagen is Australian grass-fed bovine, and its serve is 15g against True Protein's 10g, so you get more collagen a scoop. True Protein is made in Australia and uses grass-fed bovine, but it does not state the country the bovine is from. Chief states both the sourcing and the larger dose.

You want the lower price per gram

Chief is cheaper for the collagen you actually get: about $11.80 a 100 grams against True Protein's $16. True Protein's serve is a smaller 10g, so it looks a little cheaper per serve, about $1.60 against Chief's $1.77. Weigh it by the gram rather than the scoop, though, and Chief is the cheaper of the two.

Where True Protein is the better choice

You want Vitamin C built in

True Protein adds Vitamin C to its collagen, and your body uses Vitamin C in collagen formation, so having it in the same scoop is a genuine convenience. Chief keeps its collagen pure, which means you would take your Vitamin C separately, from food or another supplement. For the two together in one scoop, True Protein does that and Chief does not.

You want more flavours or a smaller serve

True Protein offers a Natural plus five flavours, including chocolate, fruit punch and vanilla, more than Chief's three. Its serve is also a smaller 10g, so if you prefer a lower daily dose or you like to rotate flavours, it fits that. Chief keeps a tighter, simpler range with a larger serve.

You want a HASTA-certified collagen

True Protein sells a separate HASTA-certified collagen, tested against banned substances, built for athletes who are drug tested. Chief does not hold HASTA on any product. For anyone competing under testing who wants a certified collagen, True Protein has that option in its range and Chief does not.

Pure collagen or a collagen and Vitamin C formula

This is the real choice. Chief keeps its collagen pure, 100% collagen with nothing added, and publishes its testing for heavy metals, pesticides and glyphosate. True Protein builds Vitamin C into the collagen, has more flavours and offers a HASTA-certified collagen for drug-tested athletes. Neither is wrong. Chief is the cleaner, cheaper-per-gram, tested single ingredient; True Protein is a fortified formula with more options. 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 are pregnant, breastfeeding or managing a health condition, check with your healthcare provider before adding a new supplement. And if you compete under drug testing, look for a certified product, such as True Protein's HASTA collagen.
