Why Fine Kelp Powder Is Better for Absorption
Smaller particles = larger surface area
When kelp is ground into a very fine powder, each particle is tiny. Tiny particles have more total surface area, which makes it easier for digestive enzymes to break them down.
Better breakdown = better absorption of nutrients
Mixes more evenly with food
Fine powder blends smoothly into wet or dry pet food. This prevents clumping, meaning pets are more likely to eat the full dose and their digestive system can process it evenly.
More consistent intake = more reliable benefits
Faster digestion
Coarser powders take longer for the stomach to process. Pets—especially cats and dogs—have relatively fast digestive systems. If the kelp isn't broken down quickly enough, some nutrition can pass through unused.
Fine powder ensures nutrients are available when the body is ready to absorb them
Gentler on the digestive system
Fine powder causes less irritation and is easier for sensitive stomachs.
Better tolerance, especially for pets with digestive issues
More bioavailable nutrients
Bioavailability = how much of a nutrient the body can actually use. Finely milled kelp makes iodine, minerals (like magnesium, calcium), and trace nutrients easier for the body to absorb.
Higher bioavailability = stronger health benefits (coat, thyroid support, immunity, etc.)
Simple Summary
Kelp fine powder is better absorbed because its tiny particles break down faster in the digestive system. This gives pets more access to the important nutrients in kelp—like iodine, minerals, and vitamins—and ensures they get the full benefit from each serving. Coarser kelp passes through the system more slowly and may not release nutrients as effectively.
