The first six hours are the whole point.
Colostrum is the milk a cow makes for her newborn calf, and its immune factors fall fast after birth. We collect only the surplus from that first-day milking, after the calf has been fed, and dry it gently so what was in the pasture ends up in the jar.

Why colostrum
What a daily scoop does for you
Colostrum carries immunoglobulins, lactoferrin, growth factors and proline-rich polypeptides. Together they support the gut wall, the immune system and recovery, which is why people notice it in six different ways.
-
Immune support
IgG antibodies help prime the body's natural defenses against everyday pathogens and seasonal stress.
-
Gut lining and digestion
Lactoferrin and growth factors nourish the gut wall, calm inflammation and support a balanced microbiome.
-
Training recovery
IGF-1 supports lean muscle repair and shorter recovery between hard sessions.
-
Skin, hair and nails
Growth factors encourage cellular repair and collagen production for clearer skin and stronger hair.
-
Focus
Neuropeptides and growth factors support neurological health and everyday mental sharpness.
-
Steady energy
Naturally occurring vitamins, minerals and peptides help keep energy even through the day.
Our sourcing
Calves first, then the jar
Quality starts in the field. Our colostrum comes from grass-fed, pasture-raised U.S. herds, and every calf gets its full share before we collect any surplus.
-
First-day milking only
Collected within six hours of calving, when IgG, IGF-1 and lactoferrin are at their peak.
-
Grass-fed, pasture-raised
Cows on open pasture year-round. No added hormones, no antibiotics, no GMO feed.
-
Calf-first policy
We never trade animal welfare for volume. Only the surplus is collected.
-
Cold-processed and tested
Low-heat drying protects fragile proteins. Every batch is tested independently for purity and potency.
Simple to use
One scoop, once a day
Three grams is all it takes. Mix it into anything; it tastes mildly creamy and dissolves quickly.
Measure one scoop
The scoop is in the jar. New to colostrum? Start with half a scoop for the first week.
Stir into a drink
Water, milk, a smoothie or yogurt. Avoid boiling-hot liquids, which damage the proteins.
Take it on an empty stomach
About 30 minutes before breakfast is ideal for absorption.
Give it a month
Most people notice digestion and energy changes within two to four weeks of daily use.
What's inside
One ingredient, four things that matter
The label says bovine colostrum and nothing else. Here is what that single ingredient contains and why each part is there.
-
Immunoglobulins (IgG)
At least 25% by weight. The antibodies that help neutralize pathogens and support immune defense.
-
Growth factors (IGF-1, TGF-β)
Naturally occurring peptides that support muscle synthesis, cellular repair and tissue regeneration.
-
Lactoferrin
An iron-binding protein with antiviral, antibacterial and anti-inflammatory properties.
-
Proline-rich polypeptides
Immune-modulating peptides that help regulate both over- and under-active immune responses.

Not all colostrum is collected the same way
Most of the difference between products is decided before the powder exists: when it was collected, whether it was defatted, and whether anyone tested it.

Average rating from verified buyers★★★★★
“Best recovery supplement I've used”
I'm a competitive cyclist and this has cut my recovery time. My legs feel fresher the day after hard rides and I got sick far less this season.
★★★★★
“My skin has never looked better”
I started it for immunity, but my skin changed first. Clearer, brighter, and my friends keep asking what I'm doing differently.
★★★★★
“You can taste that it's the real thing”
The rich yellow color and creamy taste tell you immediately this is real, first-milking colostrum. The transparency about IgG and sourcing sold me.
★★★★★
“Finally something that works for immunity”
I used to catch every cold. Four months on BIOMIXA and I haven't had one. The whole family takes it now.
★★★★★
“It checks every box I look for”
First-day milking, verifiable IgG, no defatting, third-party tested. I've researched colostrum for years and recommend this one.
Questions
Things people ask before their first jar

Bovine colostrum is the nutrient-dense first milk a cow produces in the hours after birth. It carries immunoglobulins (IgG), growth factors (IGF-1), lactoferrin and other bioactive compounds that support immune function, gut integrity, cellular repair and recovery in adults.
IgG and growth-factor levels are highest in the first hours after calving and fall quickly afterwards. Colostrum collected on day two or three is closer to ordinary milk. Ours is collected within six hours, after the calf has been fed.
Colostrum is a dairy product and contains a small amount of lactose, usually far less than milk. Many lactose-sensitive customers tolerate it well, but if you have a milk allergy you should not take it.
Most people report changes in digestion and energy within two to four weeks of daily use. Skin, recovery and immune benefits tend to show up over one to three months.
Mild, slightly sweet and creamy, with a natural pale-yellow color from the fat and carotenoids in pasture milk. It disappears into coffee, smoothies or yogurt.
