Built for a daily ritual

Neutral taste, dissolves clean in water, milk or a smoothie. One scoop each morning, 30 servings per jar.

How to use

1

Measure. One level scoop, 2,300 mg. The scoop is in the jar, under the powder.

2

Mix cold. Water, milk or a smoothie at room temperature. Avoid boiling liquid - heat degrades the protein fraction you are paying for.

3

Time it. Morning, on an empty stomach, around 20 minutes before food. It gives the proteins a clear run.

4

Stay with it. Most people report a difference somewhere between week two and week four. Colostrum rewards consistency, not intensity.

Frequent questions

Both carry the same standard: 25% IgG. What differs is the serving. The powder is a 2,300 mg scoop, so one serving delivers 575 mg of IgG. A capsule holds 500 mg and delivers 125 mg. Powder for the larger daily dose at home; capsules for convenience on the road.
No - they are the same concentration. Percentage is concentration, not dose. What reaches you is milligrams per serving, and the powder wins that comparison by a wide margin thanks to the scoop size. Both numbers are on both labels so you never have to take our word for it.
Faintly milky and slightly sweet. In coffee or a smoothie it disappears entirely. In plain water you will notice it, but nobody has ever called it unpleasant.
Colostrum is very low in lactose and most lactose-intolerant people tolerate it without trouble. If your intolerance is severe, start with half a scoop. It does contain milk protein, so it is not suitable for a dairy allergy.
Digestive changes tend to come first, often in the second or third week. Anything to do with immunity or recovery is slower and shows over four to six weeks of daily use.
Pasture-raised, grass-fed herds in the United States. Collected only after the calf has had its fill. Every batch is tested by a third-party laboratory and the certificate is available on request.
