Seaweed Derived Calcium - A digestive buffer

Seaweed-derived calcium, specifically sourced from red algae (Lithothamnion) found in the ocean near the coast of Iceland, is used as an Acid Buf in certain supplements. Lithothamnion has a unique honeycomb structure, which provides a large surface area of more than 10m2 per gram. This structure allows for a slow release of bio-available minerals, including calcium, magnesium, and silicon. 

The slow release of minerals from Lithothamnion makes it an effective buffering agent. It has been observed to have a longer buffering action compared to other commonly used substances such as limestone or sodium bicarbonate. This means that it can help regulate acidity levels in the digestive system for an extended period. 

Studies have shown that Lithothamnion exhibits significant buffering action for around 4-6 hours under simulated in vitro stomach digestion conditions. This indicates its potential to neutralise excessive stomach acid, promoting a more balanced pH in the digestive tract. 

Additionally, Lithothamnion has been found to stimulate in vitro hindgut fermentation activities. This suggests that it may have a positive impact on the microbial population and activity in the hindgut, which is important for optimal digestion and nutrient absorption. 

It's important to note that while seaweed-derived calcium can be a valuable component of Ulcabuf and other similar supplements, it should be used as part of a comprehensive approach to equine digestive health. This may include appropriate feeding practices, forage quality, and management strategies. Consulting with a veterinarian or equine nutritionist is recommended to ensure the most suitable use of Ulcabuf or any supplement containing seaweed-derived calcium for your horse's specific needs.

"My 6 year old's whole demeanor had changed to the point of her becoming dangerous to approach, rug, feed, catch etc., let alone ride! Then, three weeks ago I started feeding her UlcaBuf. I changed nothing else. Two weeks in and she was a different horse! She is friendly and happy to see me and almost even sooky! I am so impressed with your UlcaBuf, that I would recommend it whole heartedly. Thank you so much."- Sharyn

"Hey I just wanted to let you know I picked up a small 1kg bucket of UlcaBuf to get my horses started on it and my extremely girthy/ very dramatic about it gelding who is constantly fighting ulcers. After 48hrs on UlcaBuf I put his saddle on today and as always carefully and slowly cinched him and it?s the first time in a very very long time he didn?t blow apart! Words cannot describe how amazed and grateful I am to this product! I?m super stoked with it. Frosty is never coming off it ever! Amazing!?- Lou Harris
