Acid Buf® Marine Calcium is a premium marine-derived mineral supplement produced from naturally calcified red marine algae. It provides horses with a highly available source of calcium and magnesium, while its unique porous structure provides natural, sustained buffering properties within the digestive system.

Unlike ordinary limestone calcium, Acid Buf has a distinctive honeycomb-like structure with a very large surface area. This allows the marine minerals to be released gradually, providing longer-lasting buffering action.

Acid Buf is an excellent nutritional ingredient for horses requiring additional calcium, magnesium and digestive pH support, particularly performance horses, horses receiving grain or concentrate feeds, horses during periods of travel or stress, and horses requiring additional gastric and hindgut nutritional support.

What is Acid Buf?

Acid Buf is produced from calcareous marine algae harvested from marine environments around Iceland and Ireland.

During growth, the red algae naturally accumulate minerals from seawater and develop a highly mineralised calcified structure.

After harvesting, the material is washed, dried and finely ground to produce a natural marine mineral feed ingredient.

The resulting product provides a naturally occurring combination of calcium, magnesium and other marine minerals.

Natural Marine Calcium for Horses

Calcium is one of the most important minerals in equine nutrition.

It is required for:

• Normal bone development and maintenance
• Skeletal strength
• Muscle contraction
• Normal nerve function
• Enzyme activity
• Normal metabolic processes

Maintaining an appropriate calcium-to-phosphorus balance is particularly important when formulating horse diets.

Acid Buf provides a naturally derived source of calcium that can be incorporated into a correctly balanced equine ration.

Natural Source of Magnesium

Unlike standard calcium carbonate or limestone, Acid Buf also naturally provides magnesium.

Magnesium plays important roles in:

• Normal muscle function
• Nerve function
• Energy metabolism
• Bone structure
• Electrolyte balance
• Numerous enzyme systems within the body

This combination of calcium and magnesium makes Acid Buf particularly interesting when formulating balanced equine supplements.

Digestive & Gastric Support

One of the major advantages of Acid Buf is its natural buffering capacity.

The calcified marine algae have a highly porous, honeycomb-like structure providing a very large surface area.

This structure allows Acid Buf to interact with acids gradually rather than dissolving immediately.

Research involving Acid Buf has demonstrated buffering activity over approximately 4–6 hours under simulated in-vitro equine stomach conditions.

This makes Acid Buf useful as part of a properly formulated feeding program designed to support normal gastric pH and digestive comfort.

Hindgut Support

Maintaining a stable digestive environment is important for normal fibre fermentation.

Acid Buf may help support normal digestive pH conditions and fermentation activity, particularly in horses receiving diets containing significant amounts of grain or concentrates.

It can be particularly useful as part of the nutritional management of horses exposed to:

• High-performance workloads
• Grain and concentrate feeding
• Competition
• Regular transportation
• Changes in routine
• Changes in diet
• Limited grazing
• Stable confinement
• Other periods of increased nutritional demand

Typical Nutritional Composition

Acid Buf is naturally rich in:

Calcium: approximately 28–30%
Magnesium: approximately 4–5.5%

As a naturally derived marine product, exact mineral analysis can vary according to product specification and batch.

Feeding Guide for Horses

A commonly used equine feeding rate is approximately:

10g per 100kg bodyweight per day.

As a general example:

250kg pony: approximately 25g per day
400kg horse: approximately 40g per day
500kg horse: approximately 50g per day
600kg horse: approximately 60g per day

Mix thoroughly through the horse's normal feed.

The appropriate amount should take into account the horse's complete diet, including calcium and magnesium supplied by pasture, hay, concentrates and other supplements.

Important Feeding Information

Acid Buf should be incorporated into a properly balanced equine diet.

When using Acid Buf primarily as a calcium source, calculate the horse's total dietary calcium and phosphorus intake to ensure the overall calcium-to-phosphorus ratio remains appropriate.

Take particular care when combining Acid Buf with other:

• Calcium supplements
• Limestone
• Dolomite
• Vitamin and mineral supplements
• Balancers
• Complete fortified feeds
• Magnesium supplements

For horses with diagnosed gastric ulcers or other gastrointestinal disease, seek veterinary advice. Acid Buf is a nutritional feed ingredient and should not be represented as a replacement for veterinary diagnosis or prescribed ulcer medication.

Always provide unlimited access to clean, fresh drinking water and suitable forage.

Ideal for Equine Supplement Formulation

Acid Buf can also be a valuable raw ingredient when formulating equine nutritional products because it can provide both marine-derived minerals and buffering capacity.

Potential applications include:

• Equine calcium supplements
• Gastric-support supplements
• Digestive-support formulas
• Vitamin and mineral blends
• Breeding and growing-horse supplements
• Performance-horse supplements
• Hindgut-support formulations
• Mineral balancers

Storage

Store in a cool, clean and dry location.

Keep the product tightly sealed and protected from moisture, pests and contamination.

Why Choose Acid Buf Marine Calcium?

Acid Buf provides more than a conventional source of calcium.

Its naturally calcified marine-algae structure supplies calcium and magnesium together with sustained buffering properties, making it a versatile ingredient for modern equine nutrition.

For horse owners or supplement manufacturers looking for a natural marine mineral source that can support both mineral nutrition and normal digestive pH, Acid Buf is an excellent option.
