What Is Citrus Bioflavonoid Granular 50%?

Citrus Bioflavonoid Granular 50% is a standardized extract derived from the peels and pulp of citrus fruits, typically oranges, lemons, and grapefruits. The “50%” refers to its minimum total bioflavonoid content, making it a reliable mid-potency grade widely used in supplements and functional formulations.

The granular format sets it apart from conventional fine powders. Granular material offers:

• Better flowability in tablet and capsule lines

• Lower dusting during production

• More consistent blending

• Improved compressibility

These characteristics make it a preferred choice for manufacturers looking for efficiency and stability in high-throughput environments.

Key Active Compounds

Citrus bioflavonoids contain a naturally occurring complex of polyphenols, such as:

• Hesperidin

• Naringin

• Quercetin

• Rutin

• Eriodictyol

Each compound contributes unique antioxidant and anti-inflammatory properties, making the ingredient multifunctional and highly versatile.

Health Benefits & Functional Properties of Citrus Bioflavonoid Granular 50%

Citrus bioflavonoids have been studied extensively for their wide-ranging biological effects. Citrus Bioflavonoid Granular 50% offers all the benefits of traditional bioflavonoid extracts while providing superior formulation performance.

1. Potent Antioxidant Properties

Bioflavonoids scavenge free radicals, reduce oxidative stress, and support the body’s natural defense mechanisms. They complement Vitamin C’s activity and are often paired with it in supplements.

2. Supports Immune Health

Citrus bioflavonoids enhance immune cell function and improve resistance against environmental stressors. Many immune-boosting formulas include bioflavonoids to amplify the effect of Vitamin C.

3. Enhances Vitamin C Absorption & Function

A classic synergy: bioflavonoids improve Vitamin C absorption, bioavailability, and utilization in the body. This makes Citrus Bioflavonoid Granular 50% a staple in ascorbic acid formulations.

4. Cardiovascular & Capillary Support

Research has shown that citrus bioflavonoids:

• Strengthen capillary walls

• Improve microcirculation

• Reduce swelling and inflammation

• Support vascular elasticity

This makes them valuable for formulas targeting venous support, heart health, and overall circulation.

5. Anti-inflammatory Benefits

Bioflavonoids modulate inflammatory pathways and help reduce chronic inflammation, making them suitable for joint support, recovery formulas, and metabolic health supplements.

How Citrus Bioflavonoid Granular 50% Is Manufactured

Understanding the manufacturing process helps buyers evaluate quality, safety, and regulatory compliance.

1. Raw Material Sourcing

Citrus peels (mostly orange, lemon, grapefruit) are washed, dried, and selected for extraction. High-quality suppliers use non-GMO and pesticide-controlled sources.

2. Solvent Extraction

The peels undergo water or ethanol-water extraction to break down the plant matrix and isolate bioflavonoids.

3. Concentration & Purification

Extracts are filtered and concentrated under vacuum to maintain the stability of the polyphenols.

4. Standardization

Bioflavonoid concentration is adjusted to achieve 50% purity, ensuring consistent potency across batches.

5. Granulation

This is where granular format is produced. Wet granulation or fluid-bed granulation techniques convert the extract into free-flowing granules.

6. Drying

Careful drying removes excess moisture while preserving active compounds.

7. Final Quality Testing

HPLC testing ensures total bioflavonoid content meets or exceeds 50%. Additional tests include:

• Heavy metal analysis

• Microbial count

• Solubility

• Particle size distribution

8. Packaging & Storage

Finished product is packed in:

• 20–25 kg fiber drums

• HDPE-lined bags

• Moisture-proof packaging

Stored at room temperature, protected from moisture and direct sunlight.
