Clover extract is good for you, however it usually provides a little less protein than alfalfa, usually between 12 and 18% crude protein by dry weight. But clover is better than other plants in having minerals. It has a lot of:

• Phosphorus: Necessary for bones and energy metabolism
• Copper is important for making connective tissue and processing iron.
• Manganese: Important for healing wounds and building bones

Both plants have a lot of minerals, but alfalfa usually has a little more overall mineral density. But the exact mineral profile can change based on things like the quality of the soil, the conditions in which it grows, and the type of alfalfa or clover employed.

Comparative nutrient profiles: crude protein, fiber and bioactive markers

To truly understand the nutritional value of alfalfa and clover extracts, we need to look beyond just protein and minerals. Let's examine their comparative nutrient profiles in more detail, including crude protein, fiber content, and bioactive compounds.

Crude Protein

As mentioned earlier, alfalfa typically has a higher crude protein content than clover. This makes alfalfa extract particularly valuable in applications where high protein content is desired, such as in animal feed or protein supplements for humans.

However, it's important to note that crude protein content alone doesn't tell the whole story. The quality of the protein, determined by its amino acid profile, is equally important. Both alfalfa and clover provide a good balance of essential amino acids, making them valuable plant-based protein sources.

Fiber Content

Both alfalfa and clover are excellent sources of dietary fiber, which is crucial for digestive health and can help maintain healthy cholesterol levels. However, there are some differences in their fiber profiles:

Alfalfa extract typically contains:

• Moderate levels of soluble fiber, which can help lower cholesterol and regulate blood sugar levels

Clover extract, on the other hand, generally contains:

• 20-25% crude fiber
• A more balanced ratio of soluble to insoluble fiber
• Higher levels of pectin, a type of soluble fiber with potential cholesterol-lowering effects

Bioactive Markers

Both alfalfa and clover extracts contain a variety of bioactive compounds that contribute to their potential health benefits. These include:

Alfalfa bioactive compounds:

• Saponins: Known for their cholesterol-lowering and anti-inflammatory properties
• Flavonoids: Powerful antioxidants that may help protect against cellular damage
• Phytoestrogens: Plant compounds that may help balance hormone levels
• Chlorophyll: A potent antioxidant with potential detoxifying properties

Clover bioactive compounds:

• Isoflavones: Particularly high in red clover, these compounds have estrogen-like effects and may help alleviate menopausal symptoms
• Coumarins: Natural compounds with potential blood-thinning effects
• Phenolic compounds: Antioxidants that may help protect against oxidative stress

While both plants offer a rich array of bioactive compounds, the specific concentrations can vary widely depending on factors such as plant variety, growing conditions, and extraction methods. This underscores the importance of choosing high-quality extracts from reputable sources to ensure consistent potency and efficacy.
