Grapefruit Products FAQ's

FAQ's from NOW


What actually are these Grapefruit-derived products?

According to the manufacturer of our Grapefruit Complex Liquid (GCL), this product is not just an extract of grapefruit seed but rather a complex of quaternary ammonium compounds derived from the polyphonic compounds of grapefruit seed and pulp. Through this proprietary process, the bioflavonoids naringin, hesperidin, apigenin rutinoside, quercetin glycoside and others are converted to a complex of unique compounds that resemble other well-known ingredients used in formulations to protect them from contamination.

This product has not been diluted with water or other additives and therefore is the strongest GCL available in the market. In its pure form, GCL is 60% actives and 40% USP Glycerin. This product starts with natural grapefruit pulp and seed and is run through a multi-step proprietary process to yield a complex of chemical compounds proven safe when used as directed.

Is this still a safe product?

We first introduced our Grapefruit Complex Liquid (GCL) as Grapefruit Seed Extract (GSE) in 1991 and have not experienced any cases of toxicity related to the suggested use of the product. According to the 3rd party laboratory tests performed by the manufacturer, this product is biodegradable, environmentally safe and non-toxic when used as suggested. To ensure purity and safety, GCL is tested for heavy metals, aerobic plate count and chlorinated hydrocarbon pesticides. NOW Foods Grapefruit seed extract contains no parabens.

Your label suggests a mouthwash/gargle, but then states Not For Internal Use. Can you clarify?

NOW Grapefruit Complext Liquid (GCL) is extracted from the seed, rind and pulp of the grapefruit. Because of FDA regulations governing the dietary supplement industry, and the fact that undiluted GCL should not be ingested, we include the Not For Internal Use warning on our label. GCL is safe to ingest when diluted properly. Add 2 to 3 drops of GCL to 8 ounces of water for an effective mouthwash, or for internal use. Never use this product full strength, as it is very potent and may cause irritation!

What is Grapefruit Fiber and what part of the grapefruit is it derived from?

Grapefruit Fiber is a dietary fiber supplement derived from the pulp and rind of the grapefruit. This product contains 23% to 33% pectin, and is a good source of fiber. Although Grapefruit Fiber is not an organic product, NOW carefully screens all of its raw materials to ensure the absence of microbes and contaminants. A great fiber alternative for persons allergic to certain grains like wheat.
