Histamine Support (DAO):

- Take 10 minutes before consuming histamine-rich foods.
- Recommended dosage is 1 to 3 capsules per meal, or as advised by a healthcare professional.
- Begin with 1 capsule and gradually increase to the desired dose (refer to "Potential Issues" for guidance).

Note: Diamine oxidase (DAO) is not limited to specific animals or plants. It is present in various sources, including porcine kidneys, green pea sprouts, and the human placenta. In mammals, histamine is neutralized through either methylation by histamine N-methyltransferase or oxidative deamination by DAO. Organs such as the kidneys, thymus, intestines (likely placenta) that aid methylation processes with compounds like endogenous methyl groups, B12, folate, and selenium are beneficial for supporting histamine health. Additionally, legumes like lentils, beans, and peas synthesize DAO during germination.

General Use:

- Can be taken with or without food.
- Suggested dosage is 6 capsules daily in divided doses or as directed by a healthcare provider.
- Start with 1 capsule and gradually work up to six capsules daily (refer to "Potential Issues" for guidance). Ensure doses are spaced at least three hours apart to enhance tolerability.

Please consult the product packaging for accurate instructions on how to use the product.

The Active Ingredient Is: Vitamin B12

Vitamin B12 is a vital nutrient key to normal red blood cell creation and nerve system function.

This product sources vitamin B12 from grass-fed cow kidney, presented as a natural nutrient within freeze-dried organ tissue from grass-fed cattle.

What Does Vitamin B12 Do?

Vitamin B12 helps with normal red blood cell production and supports nerve health, with extra links to immune function and antioxidant protection as part of everyday metabolism.

Dr. Fairweather-Tait of University of Cambridge discovered that vitamin B12 status relates to these crucial physiological roles, reinforcing the nutrient’s role in daily wellbeing and normal bodily processes.
