Colostrum Brands Compared (2026): Price per Gram and IgG for 9 Brands

Updated October 09, 2026

Among nine popular bovine colostrum powders checked on October 9, 2026, the cheapest per gram of claimed IgG was Nutricost (about $0.59 per gram of IgG), while ARMRA cost the most per gram of powder (about $0.98) and does not publish an IgG figure. Five of the nine brands do not disclose IgG at all, so price per gram of powder is the only fair comparison for them.

Key takeaways

• Compare price per gram and price per gram of IgG, not price per tub: tubs range from 85 g to 453 g and servings from 1 g to 5 g.
• Only 4 of 9 brands state an IgG percentage (Nutricost 30%, BIOMIXA 25%, FOLQS 21%, Sovereign 15–25%). ARMRA, WonderCow, Cowboy, NOW and Codeage do not.
• None of the nine publishes a batch Certificate of Analysis (COA) we could find, so every IgG and "third-party tested" claim is the brand's own statement.
• Cheapest per gram of powder: Nutricost ($0.18) and NOW ($0.24, but it contains added maltodextrin and lecithin). Most expensive: ARMRA ($0.98).
• BIOMIXA is our own brand. On these numbers it sits in the middle: $0.67 per gram and about $2.67 per gram of claimed IgG.

The comparison table

Prices are one-time (not subscribe-and-save) prices seen on the date checked, from Amazon unless the brand site was the only live source. Serving size is what the brand lists; where it doesn't print one, we divided the tub by its stated number of servings.

How we calculated it

Three numbers do most of the work:

1. Price per gram of powder = price ÷ grams in the tub. This is fair across serving sizes, because a "serving" is whatever the brand decides it is (ARMRA and Codeage use 1 g, Sovereign uses 5 g).
2. IgG per serving = serving grams × IgG %. For example, a 3 g serving at 30% IgG gives 0.9 g of IgG.
3. Price per gram of IgG = price per gram ÷ IgG fraction. At $0.18 per gram and 30% IgG, that is $0.18 ÷ 0.30 ≈ $0.59 per gram of IgG.

IgG (immunoglobulin G) is the standard quality marker for colostrum, but it is not the only thing that matters: lactoferrin, growth factors and whether the product is whole or "concentrated" also differ. See our IgG percentage guide and IgG explainer for what the number means.

Brand by brand

Nutricost Colostrum 30%

The lowest cost per gram and per gram of claimed IgG in this group, with a stated 30% IgG. The trade-offs: the brand doesn't say where the colostrum comes from or how it is dried ("made in the USA using globally sourced ingredients"), and its testing claim is not backed by a public COA.

NOW Foods Colostrum Powder

Cheap per gram, but it is not single-ingredient: the label lists sunflower lecithin and maltodextrin, and no IgG figure. Its retail listings also disagree on serving size (2.47 g vs 1.65 g), so check the tub you actually receive.

Sovereign Laboratories Colostrum-LD

Big 453 g tub with a low price per gram. It states a 15–25% IgG range rather than a single number, uses a "liposomal delivery" coating (lecithin and milk lipids), and makes no third-party testing claim. First-milking, grass-fed North American sourcing per the brand.

Codeage Bovine Colostrum

Lowest price per serving, but only because its serving is 1 g. Per gram it is mid-priced, and IgG is not disclosed.

WonderCow and Cowboy Colostrum

Both are whole, full-fat, US-farm colostrum at $0.54–0.58 per gram, with strong sourcing stories and contaminant-testing claims, but no IgG percentage. Cowboy uses a larger 3 g serving, so it looks pricier per serving than per gram.

FOLQS

States 21% IgG (about 0.42 g per 2 g serving), first-24-hour collection and US origin. At $0.67 per gram it costs about $3.17 per gram of claimed IgG, the highest of the brands that disclose it.

ARMRA

The most expensive per gram ($0.98). ARMRA sells a casein-free, fat-free "colostrum concentrate", which may well be richer in IgG than whole colostrum, but it doesn't publish the figure, so you can't verify what the premium buys. If you are weighing it, see ARMRA alternatives.

BIOMIXA Bluegrass Colostrum (our brand)

Full disclosure: this site is run by the makers of BIOMIXA. It is a single-ingredient, unflavored, grass-fed US colostrum collected within the first 6 hours after calving, with a stated IgG of at least 25%. At $79.99 for 120 g it costs $0.67 per gram, which puts it mid-pack. It is not the cheapest option per gram of IgG; we include it at the same standard as everyone else.

Which one fits you?

• Lowest cost per gram of IgG: Nutricost, if you are fine with undisclosed sourcing.
• Single-ingredient, US-sourced, IgG stated: BIOMIXA (our brand) or FOLQS.
• Whole colostrum with a farm story, flavors available: WonderCow or Cowboy.
• Large tub, low price per gram: Sovereign Colostrum-LD.
• Before paying a premium: ask any brand for a recent batch COA showing IgG and contaminant results. A reputable seller should be able to send one.

FAQ

Which colostrum brand has the most IgG?

Of the brands that state it, Nutricost claims the highest at 30%, followed by BIOMIXA (25%), FOLQS (21%) and Sovereign (15–25%). ARMRA, WonderCow, Cowboy, NOW and Codeage do not publish an IgG percentage, so they can't be ranked on it.

Is ARMRA worth the price?

ARMRA is the most expensive per gram in this comparison. Its concentrated format may deliver more IgG per gram, but because the figure isn't published, there is no way to check whether the premium is justified on IgG alone.

Why is price per serving misleading?

Brands choose their own serving sizes, from 1 g to 5 g. A 1 g serving looks cheap per serving but may simply be a smaller dose. Price per gram, and per gram of IgG when it's disclosed, compares like with like.

Are these IgG numbers verified?

No. Every figure here is the brand's own claim. We could not find a public batch Certificate of Analysis for any of the nine products. Treat IgG claims as a starting point and ask for a COA.
