What is 3,3'-Diindolylmethane?
3,3′-Diindolylmethane, commonly referred to as DIM, is a natural compound formed during the digestion of indole-3-carbinol, found in cruciferous vegetables like broccoli, cabbage, and kale. It is widely recognized for its potential health benefits, including hormonal balance and support for healthy estrogen metabolism. The compound’s CAS number is 1968-05-4, and it is also known as diindolylmethane. Its molecular formula is C17H14N2, with a molecular weight of approximately 246.31 g/mol. DIM is typically available in white to light yellow crystalline powder form, with high purity levels of up to 98% in bulk specifications. Known for its moderate bioavailability, it is often combined with bioenhancers to improve absorption. Provita Biotech is a leading bulk supplier of 3,3′-Diindolylmethane Powder in China, providing premium quality for use in dietary supplements, nutraceuticals, and functional foods.
3,3'-Diindolylmethane (DIM) vs indole-3-carbinol (I3C)
3,3′-Diindolylmethane (DIM) and indole-3-carbinol (I3C) are bioactive compounds derived from cruciferous vegetables, each with distinct properties and benefits. While I3C is a precursor that converts into DIM in the stomach, DIM is more stable, potent, and bioavailable, making it a preferred choice for health supplements targeting hormonal balance and estrogen metabolism. I3C is less expensive but has a shorter half-life and lower stability, making it less effective unless rapidly converted to DIM. Below is a detailed comparison:
| Attribute | 3,3′-Diindolylmethane (DIM) | Indole-3-Carbinol (I3C) |
|---|---|---|
| CAS Number | 1968-05-4 | 700-06-1 |
| Other Names | Diindolylmethane | 1H-Indole-3-methanol |
| Molecular Formula | C17H14N2 | C9H9NO |
| Molecular Weight | 246.31 g/mol | 147.17 g/mol |
| Appearance | White to light yellow crystalline powder | White crystalline powder |
| Purity | Up to 98% | Up to 99% |
| Bioavailability | Moderate; can be enhanced with bioenhancers | Low; requires conversion to DIM in the stomach |
| Potency | Directly active | Indirect (must convert to DIM) |
| Half-Life | Longer (up to 4 hours) | Shorter (less than 1 hour) |
| Stability | High; does not degrade easily | Low; degrades rapidly in aqueous solutions |
| Popularity | High; widely used in supplements | Moderate; less preferred due to instability |
| Pricing | Higher; reflects higher stability and potency | Lower; less stable and potent |
| Mechanism | Directly supports estrogen metabolism | Precursor that converts into DIM |
| Applications | Dietary supplements, nutraceuticals | Limited use; mostly as a precursor to DIM |
| Botanical Sources | Cruciferous vegetables | Cruciferous vegetables |
3,3'-Diindolylmethane (DIM) COA

Heavy metals, including arsenic (As ≤ 0.0045 ppm), lead (Pb ≤ 0.06 ppm), cadmium (Cd ≤ 0.0043 ppm), and mercury (Hg ≤ 0.0042 ppm), are all within safe limits as per ICP/MS analysis, ensuring exceptional safety and quality. The residual solvents are absent or below detectable levels, meeting stringent USP standards. This showcases Provita Biotech’s commitment to delivering premium-quality DIM powder with superior safety and purity, making it a trusted supplier for bulk nutraceutical applications.

Application
Enhanced Athletic Performance
D-ribose is a naturally occurring sugar that plays a crucial role in energy production. As a supplement, D-ribose helps improve endurance, speed up recovery times, and reduce muscle fatigue. It supports ATP (adenosine triphosphate) synthesis, which is essential for muscle contraction during exercise. For athletes seeking improved performance and faster recovery, D-ribose is a valuable addition to their regimen.
Chronic Fatigue Syndrome
D-ribose has shown promising benefits in supporting individuals with chronic fatigue syndrome (CFS). By helping the body regenerate ATP, D-ribose can improve energy levels, reduce fatigue, and enhance overall well-being. It supports cellular energy metabolism, making it a natural choice for people battling fatigue-related conditions.
Cardiovascular Health
D-ribose is known to support heart health by aiding in ATP production, which is vital for heart muscle function. Studies suggest that D-ribose supplementation can improve the function of the heart, especially in individuals with cardiovascular issues. It can help enhance energy production in the heart muscle, leading to better overall cardiovascular health.
DIM powder Manufacturing Process
The manufacturing process of 3,3′-Diindolylmethane (DIM) powder, achieving 99% purity and conforming to international standards and third-party quality tests, involves the following steps:
Preparation of Reaction Mixture:
Indole is dissolved in a solvent mixture of methanol and water to create a homogeneous reaction medium.Addition of Formalin:
Formalin (formaldehyde solution) is gradually added to the reaction mixture. The reaction proceeds for one hour under controlled conditions.Cooling and Precipitation:
The reaction mixture is cooled, leading to the precipitation of crude 3,3′-Diindolylmethane.Washing and Purification:
The precipitate is thoroughly washed with water to remove impurities and by-products.Recrystallization:
The crude product is recrystallized twice using ethanol to enhance its purity and achieve the desired high-quality crystalline form.Drying:
The purified 3,3′-Diindolylmethane is dried under vacuum to remove residual solvents, ensuring a final product with a purity of 99%.
This process ensures the production of DIM powder that meets stringent international standards and third-party quality requirements, suitable for use in nutraceuticals, dietary supplements, and pharmaceutical formulations.
