Bulk Indole 3 Carbinol can be found in many plants, including broccoli. There are many products in the market. How to choose the true indole 3 carbinol??And Guanjie focuses on it for many years,and we get patents about I3C. To distinguish true products from false, which can be determined through its appearance as well as other aspects and will show the production methods.
How To Distinguish The True Bulk Indole 3 Carbinol?
● Color:
Authentic I3C powder is typically off-white to slightly yellowish in color, with a fine and uniform texture. The color may vary based on the source and technique of processing, but it should be fairly uniform throughout the powder. False or lower-quality I3C powder may have a significantly different color, such as a darker or lighter shade, or may contain visible impurities or particles.

●Purity:
Authentic I3C bulk powder should have high purity, with no added fillers or other substances. False or lower-quality I3C may contain various impurities, such as debris, plant material, or other contaminants. Check the purity level that reputable suppliers will provide their COA.Guanjie not only provide COA, we also can the third party testing result, production methods and other information.
●Source:
Check the source of the Indole-3-carbinol powder. Some powder may be sourced from vegetable products such as cruciferous vegetables like broccoli, cabbage, and kale. Make sure that the source is reputable and the manufacturing processes are verified.
● Odor:
The odor of the Indole-3-carbinol (I3C) powder can be one indicator of its authenticity, but it is not always a reliable indicator. I3C(Indole-3-carbinol) powder that has a pungent, sulfurous or chemical odor is more likely to be a false product. Authentic typically has a slightly floral or vegetable-like smell, similar to that of the vegetable or plant it was extracted from.
● Testing results
In general, suppliers will provide their I3C for purity, potency, and potential contaminants. Therefore, it's essential to check the testing results before making a purchase.This is Guanjie's result.

To determine if an I3C powder is authentic, you can ask the supplier for their test results of the product. You can ask them for testing report. Such as High-Performance Liquid Chromatography (HPLC), Gas Chromatography-Mass Spectrometry (GC-MS), or other analytical methods, to verify the purity and potency of the powder. These tests can detect any contaminants or other ingredients that might have been added to the powder. I3C Indole-3-carbinol bulk powder that is free from harmful contaminants and additives and has a high purity level and potency is more likely to be authentic.
What Are The Extraction Methods Of Bulk Indole 3 Carbinol?
● Steam Distillation:
In this method, the vegetables are first chopped into small pieces, then exposed to steam until the cells break down, releasing the I3C compound. The steam containing I3C is then condensed, and the resulting distillate that contains I3C is collected.
●Microwave-assisted extraction:
This method uses microwave energy to extract I3C from the vegetables. The vegetables are mixed with a solvent such as water, and the mixture is heated using microwave energy to break down the cells and release the I3C compound. The resulting mixture is filtered, and the solvent is evaporated to obtain the I3C extract.
●Supercritical fluid extraction:
This technique uses supercritical carbon dioxide as a solvent to extract I3C from vegetable material. The carbon dioxide is pressurized past its critical pressure and temperature and then passed through the material. The CO2 dissolves the I3C, and as the pressure drops, it is recovered and then evaporated.
