Best Colostrum Supplements of 2026

Forty percent IgG, or 400 mg per serving, is the highest stated percentage on any capsule in this group, and it comes in a 240-capsule bottle that costs less than any other capsule here. That combination is unusual enough that we checked the label twice.

The rest of the spec sheet is clean: 1,000 mg of grass-fed bovine colostrum per serving from first milking, non-GMO, free of soy, gluten, wheat, eggs, shellfish, peanuts, and tree nuts, and third-party lab tested for potency. Nothing added, nothing fancy.

For a first capsule routine, or for anyone who wants a small daily dose without paying premium prices, this is the one we point to. The label hands you a potency figure you can compare directly with the powders, which is more than several capsules here manage.

Two hundred forty vegetable capsules of whole colostrum, 25% naturally occurring IgG, made from the first milking of rBST-free Grade A cows and double-sealed for purity. Twenty-five percent is the lowest stated percentage in this group, and it's also roughly what unmodified colostrum runs before anyone concentrates it.

What we like is how little it asks of you. No scoop, no clumps, no milk-powder aftertaste, no decision about what to stir it into. It's the capsule that stayed in the desk drawer through our testing, and the one we hand to people who have already given up on powders. The trade-off is potency per swallow: matching a 3 g scoop of a concentrate means taking more capsules, so check the back of the bottle for what a serving actually is before you plan on a six-month supply.

It's gluten-free and antibiotic-free, and 240 capsules goes a long way whichever serving size you land on. If you want a supplement you can take with a mouthful of water and then forget about, this is the most straightforward thing on the page.

Sixty percent IgG looks like a marketing number until you multiply it: at 3,000 mg of colostrum per 3 g scoop, this powder puts roughly 1,800 mg of immunoglobulin G in a glass, against the 400 mg you get from a 40%-IgG capsule at 1,000 mg a serving. That arithmetic is why it's our top pick. Nothing else in this group delivers as much per serving, and the gap isn't small.

The rest of the package holds up. It's unflavored, so it goes into a protein shake or a glass of water without turning it into a dessert, and in a shaker bottle it comes together without the sandy residue that puts people off colostrum powders. The tub is compact enough to sit next to the blender, and 50 servings means you're not reordering every other week.

Two things to know before you commit. The 60% figure is the brand's own, as every IgG percentage in this roundup is, so treat it as the best available claim rather than a lab certificate. And unflavored isn't tasteless: in plain water it reads as milk powder. In a shake you won't notice; in a glass on its own, you will.

Grass-fed sourcing and a low-temperature process are the rest of the pitch, and 50 servings is a fair run at a daily habit. What keeps this at the top for us is the first paragraph's arithmetic: no other pick lets you clear a gram of immunoglobulin in a single serving without swallowing a handful of capsules.

Three thousand milligrams per serving, taken as three to six capsules on an empty stomach, 180 capsules to the bottle. Run the arithmetic before you order: at three capsules a day that's a two-month supply, and at six it's a month. This is a bottle you'll reorder more often than the count suggests.

The sourcing is the other half of the pitch. Grass-fed beef from New Zealand and Australian herds, made in small batches in the U.S. without GMOs, fillers, or flow agents, and third-party verified for purity. If you know the beef-organ supplement aisle, this is the same playbook applied to first milk.

We think it's the best pick here for anyone who wants a serious dose without powder. What that asks in return is pill burden: six large capsules before breakfast is a real commitment, and three is the more sensible place to start if you're new to it. Build up to the top of the label's range rather than starting there.

An eight-ounce pouch, 227 servings, a gram of colostrum per scoop, and a scoop in the bag. Single-ingredient, non-GMO, free of soy, gluten, and tree nuts, and third-party lab tested batch to batch. On paper it looks less like a supplement and more like an ingredient.

That's how we ended up using it: in yogurt, in a smoothie, stirred into warm milk. It's the cheapest colostrum per gram in this group by a wide margin, and the powder is fine and creamy rather than gritty. The catch is the serving size. One gram is a third of what the 3,000 mg powders give you, so a real daily dose means two or three scoops, and the pouch's 227 servings shrink to something closer to ten or twelve weeks. Even then, nothing else here is close on cost.

The one thing we couldn't settle is potency. There's no IgG percentage here, so you're buying on the strength of a third-party testing claim rather than a figure you can compare with the concentrates. For everyday kitchen use at the lowest cost per gram in this roundup, we still think it's the sensible buy.

Bloom's colostrum isn't just colostrum. The scoop also carries grass-fed collagen peptides, probiotics, and vitamin B12, which is why it's pitched at skin and hair as much as at gut health. Twenty-five servings, unflavored, in a tub small enough for a bathroom shelf.

That combination is both the pitch and the problem. As a daily beauty-and-gut powder it's easy to like: one scoop in a smoothie or a bowl of yogurt and you've covered three supplements at once. As a colostrum supplement it's opaque, because there's no milligram figure for the colostrum, let alone an IgG percentage, so you can't line it up against anything else on this page.

It's also the fussiest powder we tested. In cold water it clumps, and a shaker bottle leaves flecks up the sides; a milk frother, or a warm base like yogurt, oatmeal, or warm milk, gets you a smooth result. The flavor is neutral with a faint sweetness from the collagen, which disappears once it's in food.

So it's a good buy if you want one scoop doing collagen, probiotics, and colostrum at once and you're not chasing a potency number, and a poor one if colostrum is the whole point and you want to know how much you're getting. Twenty-five servings is about a month of habit, which is the right way to find out whether the combination suits you.

Several powders in this group are processed to concentrate what's inside: ARMRA strips the fat and casein, and others are built around a headline IgG percentage. WONDERCOW goes the other way, with 100% whole colostrum and nothing removed, and for a certain buyer that's the more interesting product. We like it for exactly that reason: you get the full first-milk matrix rather than a figure that reads well on a label.

Sixty servings, unflavored, and it stirs into water, a smoothie, or a protein shake. Whole colostrum keeps its fat, which is precisely why it clumps if you dump it into cold water and walk away. A frother or a shaker bottle sorts that out in seconds, and it's the trade-off you accept for the unprocessed version.

What you don't get is a stated IgG percentage, so if potency math is how you shop, this one asks you to buy the philosophy instead. What it gives you in return is a single-ingredient powder from grass-fed herds that behaves well in a blender and tastes of almost nothing.

ARMRA is the one colostrum product here you can tip straight into your mouth. The powder is fat-free and casein-free and milled fine enough that the brand recommends dry-scooping it or stirring it into a cool drink, an odd ritual the first time and a convenient one by the second week.

What's in the jar is a bovine colostrum concentrate the company claims retains 400-plus bioactive nutrients through a cold-chain process, sourced from grass-fed cows on family-owned U.S. dairy farms. It's unflavored and odorless, and it disappears into milk or yogurt without changing either.

Then there's the serving guidance, which is the detail that decides whether this makes sense: four or more servings a day for the full benefit. A 120-serving jar is a month at that rate, not four. If you're a one-scoop-with-breakfast person, you're buying a fraction of what the label describes.

It's the most recognized name in colostrum and the one people ask about, and it's genuinely pleasant to use. Whether it's worth the outlay depends on whether you'll actually take it four times a day. If you'll take one scoop in the morning, a 3 g powder gives you more per serving for a good deal less.
