Cheapest Colostrum per Gram: 9 Powders From $0.18 to $0.98

Updated November 06, 2026

Nutricost Colostrum 30% Powder is the cheapest of nine colostrum powders at about $0.18 per gram as of October 2026; ARMRA is priciest at about $0.98. That is a 5.6-fold spread. Every figure below is our own division of a seller's listed price by its stated net weight. Price per gram says nothing about what is in the powder, and only four of the nine brands state an IgG figure, so the ranking carries less weight than it appears to.

The nine powders ranked by price per gram

All prices are as of October 2026, and all weights, serving sizes and IgG percentages are seller claims. The table is sorted by price per gram. Serving sizes follow the brands' labels or are derived from net weight divided by servings. The full 9-brand comparison table adds origin and processing fields.

What the cheapest three do not tell you

Nutricost: $0.176/g

The listing says "made in the USA using globally sourced ingredients", which does not identify where the colostrum comes from. Processing is not stated, and neither is how the powder reaches a 30% minimum IgG, which is above the 21-25% claimed by the two whole, full-fat powders that give a single figure. The brand says each batch is tested by independent, ISO-accredited laboratories, but we found no public COA.

NOW: $0.242/g

This powder contains added sunflower lecithin and maltodextrin. The label shows 2.4 g of colostrum in a 2.47 g serving, which puts the price at about $0.25 per gram of colostrum itself. Origin and processing are not stated, and IgG is not disclosed. NOW's 25% IgG capsules are a different product, so that figure cannot be applied here.

Sovereign Laboratories: $0.360/g

The 15-25% IgG range is wide enough to change the value calculation by two-thirds. The powder also carries a lecithin and milk-lipid coating, and the brand does not state how many grams of each serving are colostrum, so the true price per gram of colostrum is somewhat higher than $0.36. We found no third-party testing claim.

Cost per gram of IgG: only four can be scored

IgG is the dominant immunoglobulin in bovine colostrum and is the most commonly quoted marker on labels (Hurley and Theil, 2011). It also falls sharply in the milkings after calving, and processing can change measured levels (McGrath et al., 2016; Elfstrand et al., 2002). It is therefore a more useful unit than bulk grams, but only if the percentage is real.

• Nutricost: $0.59 per gram of IgG at the claimed 30%.
• Sovereign Laboratories: $1.44 at the 25% high end, $2.40 at the 15% low end, or roughly 2.5 to 4 times Nutricost.
• BIOMIXA (the site owner's own brand): $2.67 at 25%, about 4.5 times Nutricost.
• Folqs: $3.17 at 21%, about 5.4 times Nutricost.

Some studies suggest bovine colostrum may influence certain gut or exercise-related measures, but the evidence is limited and varied (Playford and Weiser, 2021), and a lower cost per gram of IgG is not evidence of any benefit.

The IgG each undisclosed powder would need

Five brands give no IgG percentage, but the break-even is simple arithmetic: divide the price per gram by Nutricost's $0.587 per gram of claimed IgG. The result is the IgG percentage each powder would need to match it.

• NOW: about 41%
• Codeage: about 74%
• WonderCow: about 92%
• Cowboy Colostrum: about 99%
• ARMRA: about 168%, which is impossible

Sovereign, for comparison, would need about 61% against its stated 15-25%. The exercise assumes Nutricost's claim holds. If its true figure were 20%, the targets would drop by a third, and ARMRA's would still exceed 100%. ARMRA is sold as a casein-free, fat-free concentrate, so a higher IgG share than whole powder is plausible, but the brand does not state one.

Per-serving and sticker prices point elsewhere

Ranked by serving, Codeage is cheapest at $0.44, ARMRA drops to the middle at $1.00, and Sovereign is last at $1.81. None of that reflects value, because the servings range from 1 g to 5 g. ARMRA's dollar-a-serving price buys 1 g, whereas Sovereign's $1.81 buys 5 g.

Recommended intake shifts the picture again:

• ARMRA recommends 4 or more servings a day, which is at least about $3.93 daily, so a jar lasts 30 days at most.
• Cowboy Colostrum recommends 2-3 scoops a day. If one scoop is the 3 g serving, that is $3.48-$5.22 daily and the jar lasts 13-20 days, despite its mid-table price per gram.
• Nutricost at one 3 g serving a day costs about $15.84 per 30 days.

Sticker price misleads as well. NOW has the lowest at $20.54 but holds only 85 g, and Sovereign has the highest at $163.00 while ranking third per gram. To test your own dose, use the colostrum price calculator.

Label inconsistencies that affect the math

Price per gram relies only on price and net weight, so disputed serving sizes do not move it. They do affect cost per serving and any per-serving IgG claim.

• BIOMIXA (the site owner's own brand): its site lists a 3 g scoop and 60 servings, but the jar holds 120 g, which implies 2 g. The 25% figure appears only on its site, not on Amazon.
• Folqs: the 21% and 420 mg per 2 g figures come from its site, whose FAQ also mentions a 3 g serving.
• ARMRA: label transcriptions show 1 g, one review lists 2 g, and 1 g matches 122 g across 120 servings.
• NOW: older labels show 1.65 g and about 52 servings, so check the current one.

Testing claims are not test results

Six brands make testing claims: Nutricost, ARMRA, Cowboy Colostrum, WonderCow, Folqs and the site owner's own brand, BIOMIXA. We found no public COA for any of them, and ARMRA does not name its labs. For Sovereign and Codeage we found no third-party testing claim, and NOW cites an NPA A-rated GMP certification rather than a product certification. Claims about pasture, first-day collection, six-hour windows and low-heat drying are also unverified brand statements. Our buyer's guide explains what to ask a seller for.

FAQ

Is the cheapest colostrum per gram the best value?

Not automatically. Nutricost leads on price per gram and on price per gram of claimed IgG, so it has the strongest case on the published numbers. However, that case rests on an unverified 30% label claim, and the brand does not state origin or processing. Buyers who care about sourcing may reasonably pay more, provided they know the premium is buying claims rather than measured differences.

Why do brands with the same price per gram differ so much on IgG cost?

Because cost per gram of IgG depends on the claimed percentage. Two 120 g jars at $79.99 both work out to $0.667 per gram, yet a 25% claim gives $2.67 per gram of IgG while a 21% claim gives $3.17. A few percentage points shift the result noticeably, which is why an unverified or missing IgG figure limits any value comparison.

Should I trust an IgG percentage on a label?

Treat it as a seller claim until you see a batch-specific lab report. We found no public COA for any brand here that makes a testing claim. Ask a seller for the COA matching your lot number, the test method used, and whether the percentage is a guaranteed minimum or a typical value. A range such as 15-25% is at least candid about variability.

How current are these prices?

All prices were checked once and are given as of October 2026. Amazon prices can change, and coupons or subscription discounts are not included here. A price move rarely changes the extremes, since Nutricost and ARMRA sit far apart, but the mid-table is close enough that a small discount could swap positions. Recalculate before buying by dividing the current price by net weight.
