Frequently asked questions

What makes Field & Form different from other organ supplements? +

Most organ supplements are padded with fillers like magnesium stearate, silicon dioxide, or rice flour. We use none of these. Every capsule contains only whole-food organs and a bovine gelatin capsule — nothing else.

Where are your organs sourced? +

Exclusively from certified New Zealand farms. NZ has some of the world's strictest animal welfare and farming standards — cattle are pasture-raised year-round with no growth hormones and no routine antibiotics.

How are the organs processed? +

We use freeze-drying (lyophilisation), not heat-drying. This preserves the full nutrient profile including heat-sensitive enzymes, peptides, and cofactors that are destroyed by conventional drying methods.

How many capsules do I take? +

The recommended serving is 6 capsules per day, taken with food. You can split this into two doses of 3 capsules if preferred.

Are these suitable for women? +

Yes. Liver is one of the most important foods for women due to its high bioavailable iron, folate, and B12 content. We also have a dedicated Women's Organ Complex formulated specifically for female nutritional needs.
