Can I eat grapefruit or drink grapefruit juice while taking Red Yeast Rice?

Because red yeast rice may act similarly in the body to statins, you should avoid drinking grapefruit juice or eating grapefruit or marmalade while taking red yeast rice.

There is no known interaction between red yeast rice and coumadin, or any other blood thinner.
I read an article that stated that most of today’s Red Yeast Rice supplements contain the mycotoxin citrinin in them as a byproduct of the fermentation process. What assurances are there that citrinin is not in the product that I have purchased?
Doctor's Best tests for citrinin. They test in the parts per billion (ppb's) and it comes up non detectable. This is because they utilize a strain that produces extremely low levels of citrinin.
If I’m sensitive to Black Pepper, can I take BioPerine?
In very rare instances, only someone will be found to be sensitive to BioPerine.
BioPerine is a high purity compound extracted from black pepper and practically devoid other compounds of black pepper, which like safarole, are contributing to the controversy of black pepper being carcinogenic. Piperine is not a carcinogen, and at purity level of minimum 98% (BioPerine) it should not pose any concerns related to black pepper or black pepper extract (see toxicology section in our book on BioPerine).
Those people who are allergic to spices, like peppers, ginger, turmeric, should use piperine containing products with caution. The same is true with any allergen, e.g. milk products should be avoided by those allergic to milk.
The advice of nutritionists to avoid consumption of black pepper in large quantities does not prevent from obtaining benefits from 5 mg of piperine corresponding to 50 mg of black pepper (9%-10% content in raw black pepper). Especially, that our society is on average consuming daily black pepper related products in an average dose of 15-30 mg (calculated from raw black pepper in various foods) of piperine per day!!! The key for patented mechanism of piperine is to be "at the right time at the right place". In other words, to do the job of "nutritionist on call" and disappear.
I have heard that black pepper causes Prostate problems, will BioPerine do the same?
BioPerine is an extract of black pepper. Used in supplements, the quantity ingested is very small. Doctor's Best usually uses 1.5 to 5.0 mg per capsule or tablet. Limited studies indicate that Bioperine taken in very large amounts – in the order of magnitude of grams per day (there are 1000 mg in one gram), could lead to intestinal irritation in people sensitive to black pepper. I do not know of any studies suggesting that Bioperine taken in tiny amounts are detrimental to men suffering from prostate conditions.
What is modified cellulose and is it safe?
The cellulose is derived from alpha cellulose from softwood pulp. This softwood pulp may be derived from hemlock, spruce or other soft woods. It is made by cooking raw plant fiber in an aqueous solution to separate the cellulose, and then purified. It then goes through extra processing to further break down the fiber. The finished product contains no residual solvents. Excipients are needed to make the materials flow into the capsule and are extremely minute in amounts and are safe.
I am somewhat confused on how to take the DRB products. On many of the labels the Suggested Adult Use will list something along the lines of: Take 2 capsules daily, but it does not state whether they should be taken together or separately. What is the correct usage?
Unless otherwise specified on the label, the product may be taken together or separately.
Is there a limit to how many vitamins can be taken safely in one day?
While our bodies need vitamins and minerals, like other things, if taken in large amounts they may adversely affect health. Large amounts of anything can be toxic. It is important to follow all label directions and discuss any concerns with your physician.
What are the other ingredients and why are they used?
These are used as flow agents and aid in the production to keep the machinery running smoothly and the capsules filling correctly. Similarly for the croscarmellose sodium, which is cellulose (sourced from the cell walls of green plants), and is used to help disintegrate the tablet in the stomach.
What is HPLC?
HPLC stands for "High Performance Liquid Chromatography." This is an analytical lab testing method that is used to quantify the active ingredients. It is considered to be a very sensitive and accurate test. HPLC testing is a tool recognized as a quality benchmark for herbal extracts.
What is the maximum dosage for BioPerine?
Black pepper has been consumed safely for thousands of years and has been deemed GRAS (generally recognized as safe) by the FDA for the intended use as a spice. However, there are limited toxicology studies on black pepper and/or black pepper extract and limited human clinical studies as well. Therefore, it is difficult to determine an "upper limit" and none has been suggested.
