Colostrum: Backed by Science or Marketing Hype?
Colostrum is a bovine (cow) supplement marketed as a way to support immune function, gut health, skin vitality, and overall wellness.
It contains bioactive compounds that may help strengthen the body’s natural barriers (like the gut lining) which can be impacted by stress, poor diet, and other factors common in modern life.
Common Claims About Colostrum Supplements:
Supports Immune Function
Improves Gut Health
Enhances Skin and Hair Health
Boosts Athletic Performance and Recovery
Improves Metabolism
Supports Sleep
Enhances Mood and Focus
Dosage and Studies:
ARMRA is one of the most well-known brands currently selling colostrum supplements. One scoop of ARMRA contains 1 gram of bovine colostrum.
However, studies looking at gut health effects have used much higher amounts. Most range between 20 and 60 grams of colostrum, with some using around 10 grams instead.
Colostrum supplements like ARMRA typically contain 2 to 4 grams of immunoglobulins, which are considered one of the key active compounds.
Here's The Evidence:
Immune Function
Some studies suggest colostrum may reduce the risk of upper respiratory infections and boost vaccine efficacy.
Athletic studies show increases in immune factors, but overall meaningful immune benefits remain uncertain.
Gut Health
Colostrum may improve gut lining and permeability, especially in athletes.
It may reduce diarrhea linked to certain infections and support gut health in children with diarrhea.
Skin, Hair & Aging
Benefits for skin health are mainly seen with topical application, not ingestion.
Hair growth studies have been conducted in mice with injected colostrum, not humans.
Athletic Performance
Many studies focus on athletes, suggesting colostrum may reduce exercise-induced inflammation and aid recovery, possibly improving performance.
Do You Need a Colostrum Supplement?
If you're an athlete or active adult with gut concerns, colostrum supplements might offer some benefits. For other uses, better-supported supplements are available. Colostrum supplements are low risk but also low reward, and they can be expensive. Most are lactose-free, making them suitable for those with lactose intolerance.
