Is Chief or Nahla Earth colostrum better?

The colostrum is almost the same: both are single-ingredient bovine colostrum, tested to 20 percent IgG, grass-fed from the NZ Southern Alps, low-heat processed, 3g a serve. So it comes down to value and range. Nahla Earth is cheaper per gram and per serve, with a bigger tub. Chief has a lower upfront price and sits in a broader whole-food range.

Are they really the same product?

Not identical, but very close. Both are single-ingredient bovine colostrum at 20 percent IgG, grass-fed and pasture-raised from the New Zealand Southern Alps. Both are low-heat processed with no fillers, at a 3 gram serve. On the colostrum itself there is very little between them, which is why price and pack size do most of the deciding.

Which one is cheaper?

Nahla Earth, per gram and per serve. It is about $0.50 a gram and $1.50 a serve, against Chief's $0.78 a gram and $2.33 a serve. Chief's tub costs less upfront, $69.95 against $89.99, but that is because it is half the size, 90g against 180g. Over time Nahla Earth is the cheaper of the two.

They are the same, both tested to 20 percent IgG. IgG is the immunoglobulin most of the researched benefit is tied to, and 20 percent is a solid, stated level for both. Nahla Earth also publishes tested levels of IgM, IgA, IGF and TGF, while Chief states its 20 percent IgG.

Where is the colostrum from?

Both source from grass-fed, pasture-raised cows in the New Zealand Southern Alps region, and both use gentle, low-heat processing to protect the bioactives. On sourcing and processing, the two are effectively matched. Nahla Earth also offers a separate US-sourced version if you prefer that.

Do they suit vegans or people with a dairy allergy?

Neither. Colostrum is a dairy product, so both contain milk and neither suits a dairy allergy, vegans or vegetarians. Colostrum is lower in lactose than regular milk, so some lactose-intolerant people tolerate it, but if you react strongly to dairy, be cautious and check with your healthcare provider.

Chief vs Nahla Earth Colostrum: An Honest Comparison

Start with the colostrum, because that is where you would expect these to differ and they barely do. Both are single-ingredient bovine colostrum, tested to 20% IgG, grass-fed from the same NZ Southern Alps region, low-heat processed, 3g a serve, no fillers. So it comes down to value. Nahla Earth is cheaper per gram, comes in a bigger tub with twice the serves and publishes more third-party testing. Chief's genuine edge is a lower upfront tub price. Pick on value and testing against entry price.

At a glance

Start with the colostrum itself, because that is the reason to buy either and it is where these two barely differ. Both are single-ingredient bovine colostrum, tested to 20 percent IgG, the antibody that is colostrum's active ingredient. Both are grass-fed from the same New Zealand Southern Alps region, low-heat processed to protect those delicate compounds, with a 3 gram serve and no fillers. On the colostrum itself, there is very little to separate them. So this comes down to value and packaging. Nahla Earth is cheaper per gram and per serve. Its 180g tub holds twice the serves of Chief's 90g. It also publishes a bit more third-party testing, including IGF and TGF. Chief's tub costs less upfront, at $69.95 against $89.99, so it is a smaller first outlay. It also sits within Chief's broader range if you already buy from them. If you want the better value per gram, Nahla Earth. If you want the lower entry price or to buy within the Chief range, Chief.

The cost, measured fairly

All prices are AUD, read on 6 and 7 July 2026. Both are 3 gram serves, so the fair comparison is per serve and per gram. Nahla Earth is cheaper on both: about $1.50 a serve and $0.50 a gram, against Chief's $2.33 a serve and $0.78 a gram. Its 180g tub also holds 60 serves against Chief's 30.

Chief's tub is cheaper to buy in one go, $69.95 against $89.99, but only because it is half the size. So the honest read is that Nahla Earth is the better value for the same colostrum, while Chief asks less upfront and offers a smaller tub to start with. If value per gram is your measure, Nahla Earth wins it.

Where Chief is the better choice

You want the lower upfront price

The colostrum is the same either way, so this is really about the tub. Chief's is cheaper to buy, $69.95 against Nahla Earth's $89.99. That is because it is a smaller 90g tub, 30 serves against 60, so you pay less at the till even though you get less. If you are trying colostrum for the first time and would rather not commit to a bigger tub, Chief's is the smaller, lower-cost way in. Just know that per gram it works out dearer.

You already buy from Chief

If you already use Chief's collagen, whey, beef bars or organ capsules, adding its colostrum keeps everything under one brand, one order, one place to reorder. That convenience is worth something on its own. You are not trading down for it either: this is the same 20 percent IgG, grass-fed NZ colostrum as its rival, a genuinely good product in its own right.

You want a smaller tub to start

Colostrum is worth a few weeks' trial before you decide it suits you. Chief's 90g tub runs to 30 serves, about a month, a sensible amount to test how you feel without a large outlay or a big tub sitting in the cupboard. For a first run, it is the smaller of the two.

Where Nahla Earth is the better choice

You want the better value

The colostrum itself is essentially the same, 20 percent IgG, grass-fed NZ, so the question is what you pay for it. This is Nahla Earth's clearest advantage. It works out to about $0.50 a gram against Chief's $0.78, and about $1.50 a serve against $2.33. For a supplement you take daily over months, that gap adds up. So if you are paying for colostrum and not for a brand range, Nahla Earth gives you more for your money.

You want a bigger tub with more serves

Nahla Earth's tub is 180g, 60 serves, twice the size of Chief's 90g. If you take colostrum every day and know you will keep going, the bigger tub means fewer reorders and a lower cost per serve. It is the better pick for a settled, ongoing habit rather than a first trial.

You want to see more testing

Both products are whole bovine colostrum, so both naturally contain the full bioactive profile. Nahla Earth publishes a bit more of its testing, stating verified levels not just of IgG but of IgM, IgA, IGF-1 and 2, TGF-beta and vitamins. Chief states its 20 percent IgG. The colostrum is comparable, but if seeing the wider tested profile gives you more confidence, Nahla Earth puts more of it on the page.

Two very similar colostrums

It is worth being straight about this. These are not two products with a clear winner on quality. They are, for practical purposes, the same kind of colostrum: single ingredient, 20 percent IgG, grass-fed from the NZ Southern Alps, low-heat processed, no fillers. Both are good. The decision is really about value and how you like to buy. It is the cheaper-per-gram bigger tub from a colostrum specialist, or the lower-upfront tub from a broader whole-food range you may already use. Neither choice is a mistake.

Before you buy

Colostrum is a dairy product, so neither suits a dairy or milk allergy, vegans or vegetarians. It is lower in lactose than regular milk, but if you react strongly to dairy, be cautious. Colostrum is a supplement with promising but still-early evidence, strongest for upper respiratory infections and mostly studied in athletes. Keep your expectations grounded, and remember it is not a treatment for illness. If you are pregnant, breastfeeding, immunocompromised or managing a health condition, check with your healthcare provider first.

Common questions

A note on why we wrote this

Chief makes one of these products, so read this with that in mind. Chief's figures come from Chief's own product data. Nahla Earth's come from nahlaearth.com, read on 6 and 7 July 2026. These two products are unusually similar, so the comparison comes down to value, pack size and range rather than the colostrum itself. Prices change, so check both before you buy.
