Animals Thrive on Thorvin®
Thorvin is a 100% natural feed supplement for supporting optimal livestock health. It is nature’s most complete source of bioavailable minerals, vitamins, and beneficial phytonutrients. Thorvin works by filling in micronutrient deficiencies. Every ounce provides nutritional essentials, for just pennies a day.
The most nutrient‐dense kelp animal supplement on the market, Thorvin is harvested from the cleanest kelp beds on earth, and then dried at controlled low temperatures using geothermal energy to concentrate its rich nutrient profile. Thorvin contains one‐third less moisture, 30% more iodine, and is the only kelp supplement with a guaranteed selenium claim. Whether you are a formulator or farmer, you get more nutrients per pound, and feed less. Thorvin makes good business sense!
Blend Thorvin into feed formulas, or feed it alone or mixed with salt. Naturally chelated, Thorvin is bioavailable and readily utilized; it only takes small amounts to deliver benefits to livestock at all stages of life.

Free‐choice Feeding
Cattle, sheep and goats tend to self‐regulate free‐choice consumption of Thorvin to levels consistent with recommended rates. In some cases, animals will consume larger than normal quantities, but this binge typically only lasts 30‐60 days, depending on the animal’s mineral status. If higher consumption continues beyond 60 days, mix Thorvin with salt, one‐to‐one, to reduce intake, and consult your nutritionist. When feeding Thorvin free‐choice, provide one covered mineral feeder for every 25‐30 cows and every 40‐50 sheep or goats. Also make sure animals have access to salt and clean water.
