Plant-Based Fulvic & Humic Complexes for Pet Gut Health & Microbiome
BEAM Minerals7/27/2026 4 min read
If so, you aren’t alone. Digestive troubles are the single most common health issue in senior dogs [*]. Nearly 40% of older cats have gut problems, too. [*]
If your pet has trouble with digestion, plant-based minerals can help. They provide a wide range of nutrients to support gut health, with special humic and fulvic complexes that keep your pets healthy and happy as they age.
Here’s a look at how minerals can help your pet’s digestion.
What Causes Digestive Problems in Senior Pets?
Digestive issues are common in senior pets. There are two main causes: nutrient deficiencies and lack of good gut bacteria.
As dogs and cats get older their digestion slows down, which means they extract fewer nutrients from their food. Even though they’re less active, senior pets need more nutrients than they did when they were younger. [*]
Without extra support, many older pets develop nutrient deficiencies. Minerals are especially important for digestion, and low mineral intake is particularly common in senior dogs and cats. [*]
Once a pet has a mineral deficiency, further digestive issues can arise. A 2020 study found that nutritionally incomplete diets caused imbalances in pets’ gut bacteria. [*]
Lack of nutrients reduced pets’ good gut bacteria and allowed bad gut bacteria to thrive, which led to problems like diarrhea, constipation, food allergies, decreased energy, and inflammatory bowel disease. [*]
Pet Food Is Often Nutrient-Poor
Part of the issue is that commercial pet food is often low in nutrients, even if the label says otherwise.
Unlike human food, pet food is largely unregulated. Terms like "complete nutrition,” “natural,” and “nutrient-dense” have no legal definition, so manufacturers can label their pet food as they please, regardless of its actual nutrient content. Even expensive pet food brands are often inadequate.
For example, a 2016 study tested 20 commercial cat foods that claimed to provide complete nutrition, including several high-end brands.
The study found that 17 of 20 commercial cat foods were nutritionally incomplete, and 8 of them were so nutrient-poor that eating them would threaten a cat’s long-term health. [*]
As pets get older and need better nutrition, these nutrient-poor foods can become a serious problem. That’s one reason many vets recommend adding a mineral formula to your pet’s food or water.
Signs Your Pet May Need Gut Health Support
Signs of poor digestion in dogs and cats include:
Diarrhea
Constipation
Vomiting
Low energy
Decreased interest in play
Sudden refusal to eat their usual food
Eating grass
Scratching, dry skin/fur, or hot spots
Support Your Pet’s Digestion with Plant-Based Minerals
Mineral deficiencies are a common cause of digestive issues, especially in senior pets. Extra mineral support can help restore normal digestion, keeping your pet happy and comfortable as it gets older.
A 2020 study found that giving pets more minerals reduced digestive issues and balanced their gut bacteria. [*] The researchers emphasized the importance of extra nutritional support to keep pets healthy as they age. In their words:
“Accumulating evidence suggests that dietary components may impact not only GI disease, but also allergies, oral health, weight management, diabetes, and kidney disease through changes in the [gut] microbiome.”
Nutrition is one of the biggest factors in senior pets’ quality of life. A 2021 study found that high nutrient intake helped dogs and cats live longer, stay disease-free, and feel better as they entered their senior years. [*] That’s why it’s essential to make sure your pets get all the nutrients they need.
Fulvic and Humic Complexes for Extra Gut Support
Fulvic and humic complexes can also help pets with digestive issues. These compounds are derived from soil, and they’re a powerful way to support good gut health.
Fulvic and humic complexes bind to minerals and make them easier to absorb. A 2015 study found that adding fulvic and humic to a mineral formula boosted mineral absorption by as much as 250%. [*]
Fulvic and humic substances can also support your pet’s digestion. A 2026 study found that humic strengthened dogs’ gut lining cells, protecting their digestive tract from inflammation and supporting good gut bacteria. [*]
Adding fulvic and humic to food is a simple, effective way to support your pet’s gut health and ease digestive issues.
