Marine-Derived Minerals - Feed Ingredient

Marine-derived minerals are trace and macro minerals harvested from ocean-based sources such as seaweed (e.g., Lithothamnion spp.), coral, or seawater. These materials offer a naturally occurring spectrum of minerals, including magnesium, iodine, and various trace elements.

The most common mineral provided by marine sources is calcium, often in the form of calcium carbonate from calcified seaweed or coral. This form of calcium is highly bioavailable and is widely used in equine feeds and supplements to support bone health, muscle function, and overall mineral balance.

The following equine feeds, supplements and products contain Marine-Derived Minerals as an ingredient.

Frequently Asked Questions

Marine-derived minerals for horses are minerals sourced from ocean-based ingredients such as seaweed, calcified marine algae, coral, or seawater concentrates. These ingredients can supply calcium, magnesium, iodine, and smaller amounts of other trace elements depending on the source.

In horse feeds and supplements, marine-derived ingredients are most commonly used as a source of calcium carbonate or broad-spectrum mineral material. The nutritional value depends on the specific ingredient, the minerals it supplies in meaningful amounts, and how well the overall diet is balanced.

Marine-derived minerals can contribute useful nutrients, but they are only one part of a balanced feeding program and should not be assumed to replace a complete vitamin and mineral supplement.

Horse feed companies mention marine-derived minerals because horse owners often associate ocean-based ingredients with natural mineral sources. Marine ingredients can also provide recognizable sources of calcium, magnesium, or iodine depending on the raw material.

However, a marine-derived ingredient is not automatically a sign that the overall mineral program is better balanced. What matters more is whether the diet provides the right minerals in the right amounts and ratios, especially copper, zinc, selenium, iodine, calcium, phosphorus, and magnesium.

For most horses, the better question is not whether a mineral comes from the ocean, but whether the full ration is properly balanced for the horse’s forage, workload, age, and health status.

Marine-derived minerals are not necessarily organic or chelated simply because they come from an ocean-based source. “Marine-derived” describes where the ingredient comes from, such as seaweed, kelp, or calcified marine algae, while “chelated” describes a specific chemical form in which a trace mineral is bound to an amino acid or other organic molecule to improve absorption. Chelated or organic trace minerals in horse feeds are typically listed as compounds such as copper proteinate, zinc proteinate, or amino acid chelates.

In practice, many marine-derived ingredients used in horse nutrition are included as natural sources of calcium, magnesium, iodine, or broad-spectrum mineral material rather than as amino acid chelates. For example, kelp is valued mainly for iodine and naturally occurring trace minerals, while marine algae products are commonly used as calcium sources. That is different from a chelated trace mineral premix, where the mineral form is intentionally selected to improve stability and uptake in the digestive tract.

From a ration-balancing perspective, the more important question is not whether a mineral came from the sea, but whether the product provides key trace minerals such as copper, zinc, manganese, and selenium in highly available forms and in appropriate amounts. That is why many nutritionists place more value on a well-balanced supplement with 100% chelated trace minerals than on a label claim based mainly on marine-derived sourcing.

Yes, marine-derived mineral ingredients can be a useful source of calcium for horses, particularly when they are included as calcified marine algae or other marine calcium sources that supply calcium carbonate. Calcium is required for bone mineralization, muscle contraction, nerve function, and many enzyme-dependent processes throughout the body.

However, evaluating a calcium source in isolation can be misleading. What matters nutritionally is whether the total diet provides enough calcium relative to phosphorus and magnesium, and whether the horse’s forage, grain, or supplements already contribute significant amounts of those minerals. A horse may benefit from a marine-derived calcium source in one ration and not need it at all in another.

Marine-derived calcium can therefore be a good ingredient, but it should be viewed as one component of ration balancing rather than a sign that the entire mineral program is complete. The best approach is to assess how much calcium the horse actually needs and how that source fits into the overall mineral balance of the diet.

Some horse owners value marine-derived minerals because they prefer ingredients that are naturally sourced, but this should not be the main reason for choosing a supplement.

From a nutrition standpoint, the more important question is whether the supplement actually balances the horse’s diet. For most horses, that means providing the vitamins, trace minerals, and amino acids commonly lacking in hay and pasture in the right amounts and ratios. A product can contain marine-derived ingredients and still be poorly balanced overall.

For most horses, the best choice is a complete vitamin and mineral supplement such as Mad Barn’s Omneity®. Omneity is designed to balance forage-based diets by supplying 100% chelated trace minerals, vitamins, and amino acids commonly missing from hay and pasture, which makes it a more reliable nutritional choice than selecting a supplement based mainly on marine-derived sourcing.
