Curated, not stocked.
Heart & Soil applies a rigorous nose-to-tail philosophy that most supplement brands do not. Organ meats are nutritionally irreplaceable in several respects — particularly for copper, retinol, and the B-vitamin complex — and this formulation targets the specific nutrient gaps linked to poor histamine metabolism. We recommend it for patients who present with histamine sensitivity or low dietary diversity, and who want a food-based rather than synthetic solution.
About this product
Histamine & Immune
Histamine & Immune by Heart & Soil is a whole-food supplement built around a blend of grass-fed organ meats, formulated to support immune regulation and healthy histamine metabolism. Organ meats — liver, kidney, and related tissues — are among the most nutrient-dense foods available, providing a concentrated source of fat-soluble vitamins, copper, zinc, B vitamins, and bioactive peptides that most modern diets no longer include. These nutrients play established roles in immune cell function and in the enzymatic pathways that break down histamine in the body.
This product suits people who experience histamine sensitivity — seasonal or dietary — or those whose diet lacks organ meats and who want to address the nutritional gap through a convenient capsule format. It is not an antihistamine drug; it works by supporting the body's own clearance mechanisms and immune balance rather than blocking receptors.
Heart & Soil is a nose-to-tail supplement brand founded with a focus on ancestral nutrition principles. Their products are made from animal organs sourced from grass-fed cattle, freeze-dried to preserve heat-sensitive nutrients. For those curious about the nose-to-tail approach but unwilling to prepare organs at home, this is a practical entry point. As with any supplement touching immune function, it is worth discussing with a clinician if you take medication or have a diagnosed immune condition.

Common questions
Frequently asked
Is this the same as an antihistamine?
No. This is not a drug and does not block histamine receptors. It provides nutrients — such as copper and B vitamins found in organ meats — that support the enzymes your body uses to break down histamine naturally. If you need rapid symptom relief, speak to your GP about appropriate antihistamine medication.
Who is this most likely to benefit?
People who experience dietary or seasonal histamine sensitivity, those eating a low-variety diet without organ meats, or anyone whose blood work suggests low levels of nutrients like copper or zinc that are abundant in liver and kidney. A baseline blood test is a useful starting point before adding any targeted supplement.
Can I take this alongside my existing antihistamine medication?
There are no widely recognised interactions between grass-fed organ meat supplements and standard antihistamine drugs, but individual circumstances vary. If you take prescription medication for immune or allergy conditions, check with your prescribing doctor before adding this.
How long before I notice a difference?
Nutritional support for histamine metabolism tends to work gradually. Most people assess results over four to twelve weeks of consistent daily use. Changes in histamine tolerance can be subtle — keeping a symptom diary during this period is a practical way to track progress.
Is this suitable for people who do not eat meat?
No. The product contains bovine organ tissue and is not suitable for vegetarians or vegans. Check the packaging label for the full ingredient list if you have specific allergen concerns.
