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.
Grass-fed Organs blend

Take 6 capsules daily, as directed on the packaging. Heart & Soil generally recommends taking capsules with a meal to aid absorption of fat-soluble nutrients. Consistent daily use over several weeks is typically needed before noticing changes in histamine tolerance or immune resilience.
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.
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.
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.
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.
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.

Overall Sentiment

I've struggled with seasonal histamine issues for years and was sceptical that a food-based supplement could do much. But after about three weeks I genuinely noticed I was reaching for my antihistamine tablets less often. It's not an overnight fix but something does seem to shift. Takes it every morning with breakfast.

Added this alongside my usual zinc and magnesium. Hard to isolate effects exactly but my gut feels calmer after meals and I'm not getting the flushed feeling I used to get with certain foods. Will reorder.

I do think it's working — my histamine reactions to wine and aged cheese seem milder. But £75.99 is a lot to commit to monthly, especially when you can't be 100% certain how much of the improvement is the supplement versus diet changes I made at the same time. Would love a smaller starter size.

Bought after a friend with chronic hives recommended it. Three months in and I'm genuinely impressed — not cured, but the day-to-day flare-ups are much more manageable. The capsule format means I actually take it consistently, unlike when I tried cooking liver myself.

I've had histamine sensitivity for a few years and tried pretty much every approach going. This is the first supplement that feels like it's addressing the root of the issue rather than just masking symptoms. Takes a few weeks to notice anything so stick with it.
