Everything you want to know.

Colostrum is the first milk a cow produces in the 24 to 48 hours after calving. It naturally contains immunoglobulins, growth factors and other bioactive proteins.

Both carry the same standard: 25% IgG. What differs is the size of 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. Both are standardised to 25% IgG. It is the same material in two formats. 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 printed on both labels.

It is manufactured in the United States by our manufacturer, in a facility certified to NSF/ANSI 455-2 and to UL cGMP programs. The batch document for the current lot is published on the product page.

The powder is colostrum and nothing else: no fillers, no flow agents, no colourants, no sweeteners, no maltodextrin. The capsules additionally contain organic rice flour, MCT oil, L-leucine and silicon dioxide as processing aids, inside a plant-based cellulose shell. The full list is printed on both labels.

Both products contain milk protein, so neither is suitable for a dairy allergy. If you are lactose intolerant, speak to your doctor before starting. The capsule shell is cellulose, not gelatin, so it is suitable for vegetarians, but the contents are not vegan. The capsules are made in a facility that may also process soy, wheat, egg, peanuts, tree nuts, fish and shellfish.

Powder: one scoop in 6 to 8 oz of cold water or a beverage of your choice, once daily, and drink within 10 minutes of mixing. Capsules: 1 capsule, 1 to 3 times daily, preferably with meals or as directed by a healthcare professional.

The powder holds 30 servings: one level scoop a day, so a jar is a month. Individual results vary, and we do not promise a timeline.

Ask your doctor or pharmacist, particularly if you take prescription medication.

Orders leave our warehouse within 24 to 48 business hours. Delivery is three to seven business days via USPS within the contiguous United States, so in practice, most orders arrive within a week of being placed. A tracking number is emailed on dispatch.

Write to contact@maisonauro.com within 30 days of delivery with your order number and one line on what did not work, and we refund it in full. You keep the product. There is nothing to send back: an opened supplement cannot be resold, so posting it to us would only cost us both money to throw a jar away. The guarantee applies once per customer, on your first order of a given product.

Contact us within seven days of delivery at contact@maisonauro.com with your order number and a photo. We arrange a replacement or a full refund at no cost to you. This is separate from the 30-day guarantee and is not limited to one use.

By email at contact@maisonauro.com. We answer every message, usually within one to two business days.
