Is Chief or Kissed Earth collagen bar better?

Both are clean Australian collagen bars with no artificial sweeteners, so it comes down to what each is built on. Chief is a cashew and grass-fed collagen bar, which is why it carries more protein, about 16 grams a bar against roughly 7, and less sugar, sweetened with monk fruit rather than dates. Kissed Earth is a date-based bar that blends its collagen with faba bean protein and is nut-free. Choose grass-fed collagen and higher protein against a nut-free date bar.

Which one has more protein?

Chief, by roughly double. Its bar is built on cashews and grass-fed collagen, so it carries about 16 grams of protein a bar. Kissed Earth is date based, with a 14% collagen and faba bean blend, about 7 grams. The gap comes from the base, a cashew and collagen bar against a date one. If protein is the point, Chief delivers much more per bar.

Which one has less sugar?

Chief. It is sweetened with monk fruit and a little organic maple, so it is low in sugar with no added sugar or sugar alcohols. Kissed Earth is built on whole dates, a real food that is mostly sugar, so it carries more natural sugar. Both avoid artificial sweeteners, so the difference is a monk-fruit bar against a date one.

Is a collagen bar a complete protein?

Not from collagen alone, since collagen is low in some essential amino acids. Both bars address this: Chief pairs collagen with cashews, and Kissed Earth pairs it with faba bean protein. Either way, treat a collagen bar as a clean snack, not a full whey-style protein hit.

No. Both contain bovine collagen, so neither suits vegans or vegetarians, even though Kissed Earth also uses a plant protein. If you want a vegan bar, look for a fully plant-based protein bar and check its label the same way.

Chief vs Kissed Earth Collagen Bars: An Honest Comparison

Q: Which one is nut-free?

Kissed Earth. Its bar is built on dates, tahini and coconut rather than nuts, so it suits people avoiding tree nuts and peanuts. Chief's bars are nut based, in cashew, hazelnut or peanut. Note Kissed Earth still contains sesame from the tahini, and coconut, so check those if relevant.

Q: Is the collagen grass-fed?

Chief states its collagen is grass-fed. Kissed Earth describes its collagen as high-grade bovine peptides but does not state grass-fed sourcing on the bar. If grass-fed is a must, Chief states it and Kissed Earth does not.

The real difference is what each bar is built on. Chief is a nut-butter bar of cashews and grass-fed collagen, sweetened with monk fruit and a little organic maple, which is why it carries more protein at lower sugar, about 16 grams a bar. Kissed Earth is a date-based bar that blends its collagen with faba bean plant protein, so it is nut-free and whole-food but lower in protein and higher in natural sugar from the dates. Pick grass-fed collagen and higher protein against a nut-free date bar.

At a glance

Start with what each bar is made of, because that is where these two differ. Chief is a nut-butter bar built on cashews and grass-fed collagen, sweetened with monk fruit and a little organic maple. Kissed Earth is built on whole dates and blends its collagen with Australian faba bean plant protein. That difference in base is why the numbers land where they do. Chief's cashew and collagen build carries about 16 grams of protein a bar against Kissed Earth's roughly 7, at lower sugar, since Kissed Earth's sweetness comes from the dates. Both are clean, with no artificial sweeteners, so neither is junk. Kissed Earth keeps two honest edges: it is nut-free, made with tahini and coconut rather than nuts, and its faba bean protein broadens the amino profile collagen is low in. Chief is the higher-protein, lower-sugar grass-fed-collagen bar; Kissed Earth is the nut-free date one with a plant blend.

The cost, and what you get for it

All prices are AUD, read from each brand's own site on 6 July 2026. By weight the two are close. Chief is $54.95 for twelve 45g bars, about $10.20 a 100 grams. Kissed Earth is $59.40 for twelve 50g bars, about $9.90 a 100 grams, so it is marginally cheaper per gram of bar.

The picture changes when you look at what fills the bar. Chief's cashew and collagen base carries about 16 grams of protein against Kissed Earth's roughly 7, so per gram of protein Chief is far cheaper. If you are buying a bar as a protein snack, Chief is much better value. If you are buying it as a clean whole-food date bar and are not chasing protein, the per-gram price is close.

Where Chief is the better choice

You want the higher protein

The protein gap comes straight from the base. Chief builds its bar on cashews and grass-fed collagen, so it carries about 16 grams of protein a bar against Kissed Earth's roughly 7. Kissed Earth is built on dates, with a smaller 14% collagen and faba bean blend, so it eats as a whole-food date bar with less protein in it. If you are eating a bar for the protein, Chief's cashew and collagen build puts a lot more in, and per gram of protein it is cheaper too.

You want lower sugar

Sugar follows the base as well. Chief sweetens with monk fruit and a little organic maple, so it stays low in sugar with no added sugar or sugar alcohols. Kissed Earth is built on whole dates, which are a real food but are mostly sugar, so its bar carries more natural sugar. Both avoid artificial sweeteners, so this is not clean against unclean. It is a monk-fruit-sweetened bar against a date-sweetened one, and if you want the lower-sugar option Chief keeps it down.

You want grass-fed collagen and a cheaper protein cost

Chief states its collagen is grass-fed, and pairs it with cashews. Kissed Earth describes its collagen as high-grade bovine peptides but does not state grass-fed sourcing on the bar. On price the two are close, $54.95 for twelve against $59.40, or about $4.58 a bar against $4.95, but because Chief's bar carries so much more protein the cost per gram of protein is far lower. If grass-fed collagen and protein value matter, Chief has both.

Where Kissed Earth is the better choice

You need a nut-free bar

This is Kissed Earth's clearest edge, and it is a real one. Its bar is nut-free, built on dates, tahini and coconut rather than nuts, so it suits people avoiding tree nuts and peanuts. Chief's bars are nut based, in cashew, hazelnut or peanut, so a nut allergy rules them out. Kissed Earth is the option there, though note it does contain sesame from the tahini, and coconut, so check those.

You want a whole-food date bar with plant protein

Kissed Earth is a date-based whole-food bar, and it blends its collagen with Australian faba bean protein. That plant protein helps cover the amino acids collagen is low in, which is a sensible way to build a collagen bar. Chief does the same job with cashews instead. If you prefer a date-and-plant-protein bar to a nut-butter one, Kissed Earth is built that way.

You want a slightly cheaper bar by weight

Kissed Earth's bars are a little bigger and work out marginally cheaper per 100 grams, about $9.90 against Chief's $10.20. If you are comparing on the size of the bar rather than the protein in it, Kissed Earth is a touch cheaper by weight. Just remember Chief's cashew and collagen base packs far more protein into its slightly smaller bar.

Two clean bars, built differently

It is worth saying both of these are clean bars, with no artificial sweeteners and real ingredients, which is rarer than it should be. They are just built on different ideas. Chief is a nut-butter bar, high in protein from grass-fed collagen and cashews, kept low in sugar with monk fruit. Kissed Earth is a date bar, nut-free, with its collagen blended with faba bean plant protein and its sweetness from whole dates. Neither is junk. Match the one that fits your protein, sugar and allergen needs.

Before you buy

A collagen bar does not suit everyone. Chief's bars are nut based, so the cashew, hazelnut and peanut flavours are not for anyone with those allergies. Kissed Earth is nut-free but contains sesame and coconut, so check those. Both contain bovine collagen, so neither suits vegans or vegetarians. Collagen is not a complete protein, so treat either bar as a clean snack rather than a meal. If you have an allergy or a medical condition, check the label and your healthcare provider first.
