Difference Between Humic and Fulvic Acid

Difference Between Humic and Fulvic Acid

Humic Acid and Fulvic Acid are two organic compounds that play a crucial role in promoting optimal nutrient absorption and supporting overall health.

Often grouped together or viewed interchangeably (and understandably so), these organic molecules derived from decomposed plant matter actually have distinct variations in their chemical structure and functionality.

The unique health-supporting benefits of humic and fulvic acid make them essential components for a healthy lifestyle.

Since we are known for our Humic and Fulvic Acid, below we’ll share the key differences between Humic and Fulvic Acid, their specific benefits, and how Ascent Nutrition's Humic & Fulvic Acid supplement can help support your wellness goals.

What is Humic Acid

Humic Acid falls under a class of molecules called Humic substances that originate from the breakdown of organic matter over time. It is found abundantly in soils and peat produced through the microbial decomposition of plant and animal residues.

Structurally, Humic Acid is a long-chain molecule that consists of a complex mixture of dark brown to black-colored organic macromolecule elements made up of carbon, oxygen, hydrogen, and nitrogen.

Rather than one distinct compound, Humic Acid encompasses a diverse collection of polydispersed structures. The basic molecular composition contains hydrophilic and hydrophobic regions, amino acids, and many different functional groups of bioavailable nutrients.

Research continues to uncover various mechanisms behind Humic Acid’s broad health-promoting and wellness benefits.

So, what are the benefits of Humic Acid?

When it comes to health-supporting benefits, Humic Acid has been shown to encourage a healthy immune function response and support gut health by promoting the healthy growth of beneficial bacteria and promoting a balanced gut microbiome.

Another benefit of Humic Acid is its ability to bind to different toxins and help with detoxification, as well as contributing to a healthy inflammatory response, immune and respiratory support, and promoting overall health and wellbeing.

By understanding the health-supporting benefits of Humic Acid, individuals can make informed decisions about incorporating this naturally derived substance into their wellness routines.

What is Fulvic Acid

What is Fulvic Acid

Like Humic Acid, Fulvic Acid originates from the decomposition of organic plant and animal matter by microorganisms within the soil, compost, peat, and bodies of water. Fulvic Acid is actually regarded as a subcomponent of Humic Acid.

Fulvic Acid molecules have a smaller molecular size and lower molecular weight than Humic Acid. Their small size contributes to enhanced bioavailability when consumed and absorption compared to Humic Acid. Fulvic Acid also contains more oxygen components, allowing a greater diversity of active functional groups per molecule.

In addition, Fulvic Acid has around 14 tetra trillion electrons that it can donate or receive to scavenge cell-damaging free radicals throughout bodily systems, making it a valuable addition to any wellness routine.

What are the benefits of Fulvic Acid?

One of the most well-known benefits of Fulvic Acid is its ability to enhance nutrient absorption and utilization.

Its high solubility in water and chelating properties make it highly effective in promoting the bioavailability of essential nutrients, such as vitamins, minerals, and amino acids. This ensures that your body can efficiently utilize these nutrients, thereby supporting overall health.

Fulvic Acid can also support the body's natural detoxification processes by binding to and removing harmful substances, such as heavy metals, pesticides, and environmental toxins, making it an important part of any Healthy Detoxification Regimen.

Fulvic Acid also plays a crucial role in cellular energy production by promoting the efficient transfer of electrons within cells. This process is essential for the generation of ATP, the primary energy currency of cells.

Moreover, Fulvic Acid exhibits potent free radical scavenging properties, which supports the body’s natural ability to protect itself from oxidative stress and damage. This promotes a balanced immune response and contributes to overall health and well-being.

Humic Vs Fulvic Acid – What are the Difference Between Humic and Fulvic Acid

Though Fulvic and Humic Acid originate from the same soil-based process involving decay of organic plant matter, their chemical structures differ which impacts their respective mechanisms and health-supporting benefits within the body.

Read on as we compare the chemical structures, properties, and health benefits of Humic and Fulvic Acid to help you better understand their differences.

Difference Between Humic and Fulvic Acid

Size and Molecular Weight

The most distinct difference between Humic and Fulvic Acids is their size and molecular weight. Humic Acid is a larger and heavier molecule than Fulvic Acid, which results in their differing solubility and ability to interact with nutrients.

Fulvic Acid contains smaller molecules with more oxygenation, allowing superior absorption and cell permeability – even crossing the blood-brain barrier. Its electrolytic properties also promote excellent mineral transport.

It’s worth noting that Ascent Nutrition's Humic & Fulvic Acid supplement is 20X smaller than other products. The smaller size of our Humic Acid helps promote optimal absorption, allowing you to experience the full spectrum of health-supporting benefits the compounds offer.

Solubility in Water

Due to its smaller size and lower molecular weight, Fulvic Acid is more soluble in water than Humic Acid.

While Humic Acid is mostly insoluble below pH 2, Fulvic Acid has excellent solubility from pH 0.5 to 13. This higher solubility allows Fulvic Acid to be more readily absorbed by plants and humans, making it more effective at enhancing nutrient uptake and utilization.

Nutrient and Mineral Content

Both Humic and Fulvic Acids are rich in nutrients and minerals, but their compositions vary.

Humic Acid contains a wider array of nutrients and minerals than Fulvic Acid, but they are not as bioavailable due to the larger molecular size of Humic Acid.

Because of its low molecular weight, Fulvic Acid has high bioavailability. It is rich in electrolytes like magnesium, calcium, potassium, and sodium [1].

Fulvic Acid also contains diverse vitamins as well as free radical scavengers, amino acids, phytochemical compounds, and trace minerals—most of them occurring in ionic form. For this reason, Fulvic Acids are great conductors of electricity and they improve the absorption of other compounds interacting with them. This is why so many people in general, as well as our loyal customers, specifically use our Humic and Fulvic Acid supplement together with our other products and nutrients.


Humic acid is typically dark brown to black in color. On the other hand, Fulvic acid is generally lighter in color, ranging from yellow to light brown.


Specific Humic and Fulvic Acid Benefits

While both Humic and Fulvic Acids mostly offer similar health-promoting benefits, some are more specific to each compound.

For instance, Fulvic Acid is particularly effective at supporting cellular energy production and nutrient absorption due to its smaller size.

On the other hand, Humic Acid is known for its ability to support healthy immune function, including promoting gut health and supporting a healthy inflammatory response [2] [3].

Despite the differences between Humic and Fulvic Acid, the two compounds work synergistically to provide targeted health-supporting benefits when properly combined.

For example, Humic Acid may increase the permeability of cell walls by acting as a dilator while Fulvic Acid acts as a chelator by binding to and carrying minerals into the cells [3].
