Can Udo’s Oil be taken by someone with only one kidney?
Yes. Oil digestion takes place in the stomach and the wastes leave the body primarily via the intestinal tract.

Does Udo’s Oil speed up the heart beat?
No, n-3's stabilize cardiac rhythm. The lack of it can cause arrhythmia.

Is Udo’s Oil safe with beta blockers?
There are no contra-indications indicated.

What effect does Udo’s Oil have on cholesterol levels?
One of the effects is to dissolve cholesterol from the artery walls and other places where it has been stored over the years.  This dissolved cholesterol is then transported by the blood to the liver, which will then convert it into bile and discharge it into the digestive tract. 

Three points become very important here:

1. The dissolved cholesterol in the blood can raise the blood cholesterol levels for the first 3-4 weeks, until the stored cholesterol is removed.  Then the cholesterol count will go back down.
2. Unless you consume a lot of fiber with your diet, the bile that has been discharged into your digestive tract will not be locked up in the fiber, and may be reabsorbed from the colon into the blood along with the water that is absorbed at the same time.  Udo's Choice Wholesome Fast Food is a source of good fiber for this, which brings us to point three.
3. It is very important you drink at least 6-8 eight ounce glasses of water every day, to help hydrate your body and assist the fiber in absorbing the bile properly to get rid of wastes including the cholesterol-sourced bile.

Can people with gluten intolerance or celiac disease take Udo’s Oil?
It depends; some individuals who are very sensitive to oat bran/germ cannot use the oil.  Others, who are not so sensitive can. The Celiac Association of Canada says there is a problem with oats and its derivatives for celiacs. However there is research stating that oats do not contain the type of gluten which is of concern for celiacs. Oat bran is listed on the label and consumers can make an educated decision about using a product which contains it.

The following statement comes from testing the government of Germany has done on Udo’s Oil:  "The oil blend has been assayed for the content of gluten, as it contains unrefined oil pressed from oat bran and germ. The levels of gliadin are very low and in accordance with Codex Alimentarius standards. Udo's Oil™ is to be considered gluten-free as the miniscule amounts of gluten present are much lower than those found in "gluten-free" grains such as buckwheat."

Could Udo’s Oil have caused my headache?
Possibly.  Since the oil can cause fat stored toxins to be released from their storage sites in the body, these released toxins travel via the bloodstream in order to be eliminated from the body.

This elimination process may cause headaches to develop, but as cleansing progresses, they should go away.   Drink at least 2 quarts (liters) of water every day to alleviate distress. This helps flush out toxins and wastes that result from normal cellular metabolism, which can build up around your cells. Please check with your doctor if symptoms persist.
