What does one scoop contain?

What does “unflavored” mean?

What is bovine colostrum?
A cow’s first milk after calving. Products vary; check the product label for ingredients, serving size and directions.
How do I read the colostrum amount?
Each 2.55 g serving lists 2,000 mg colostrum, including 400 mg IgG. Lactoferrin and marshmallow root have separate amounts.
Does “USA brand” mean made in the USA?
IYRA is a USA brand. That describes the brand, rather than confirming where the ingredients are sourced or the product is manufactured. Contact support@tryiyra.com for questions about manufacturing origin and batch-testing documents.
Where can I read about the label and ingredients?
Start with the label guide and the colostrum and collagen comparison guide.
Can I take colostrum alongside probiotics or fiber?
These are different supplement categories. Review the products you use with your clinician, especially if you have digestive symptoms, a medical condition or take medication.
What does my daily scoop look like?
Take one included scoop (2.55 g) daily with 8 fl oz of water or a hot or cold recipe.
Does it contain milk?
Yes. Contains milk. Do not use if you have a milk allergy.
How should I store it?
Store in a cool, dry place and keep out of children’s reach. Do not use if the product is opened or tampered with, or if the safety seal is missing or damaged.
Should I check with my doctor before use?
The label advises consulting your doctor before use if you are pregnant or nursing, have an allergy or medical condition, or take medication.
Will colostrum relieve bloating?
Bloating can have several causes. Human research on colostrum and digestion is still developing, and findings vary across preparations, amounts, populations and outcomes. The research does not establish that colostrum relieves everyday bloating. If bloating persists or changes suddenly, speak with a healthcare professional.
What does “leaky gut” mean?
The term commonly refers to increased intestinal permeability—changes in how substances pass through the gut lining. It does not identify the cause of your symptoms, and it is not something this supplement can diagnose.
Does bloating mean I have “leaky gut”?
No. Bloating alone does not tell you whether intestinal permeability has changed. Gas, food digestion and other digestive conditions can contribute to bloating. A healthcare professional can help assess persistent symptoms.
Why is colostrum discussed in gut-health research?
Researchers have studied colostrum and intestinal permeability, including in people doing strenuous exercise. Findings vary with preparation, amount, population and outcome. Laboratory permeability measures differ from everyday symptom reports.
What does research say about colostrum and the gut lining?
Human research on colostrum and intestinal permeability is still developing. Findings vary across studies, and laboratory measures differ from everyday symptom reports. A healthcare professional can help assess persistent digestive symptoms.

There isn’t a single health result or timeline we can promise. Our reviews describe customers’ own experiences, which may differ from yours.
Is this meant to treat a health condition?
No. This supplement is not intended to diagnose, treat, cure or prevent disease. No product-specific health outcome is established here.
