Does Diet Rx really work?
Diet Rx is an effective natural herbal product in terms of appetite suppression. I formulated this product after years of testing different herbs and nutrients on myself and having feedback from hundreds of patients. I am very impressed at how well it works in the majority who take it. Appetite is reduced without feeling stimulated. And when appetite is reduced, fewer calories are consumed. This article reviews the benefits, side effects, provides some testimonials, a list of the ingredients and where to buy.

Ingredients it does not have
Diet Rx has no added caffeine, ephedra or ephedrine alkaloids, synephrine, guarana or stimulating amino acids. Users do not feel jittery and restless. Rather, many people report feeling more balanced with a more focused mind. Caffeine has not been added to Diet Rx although green tea extract has small amounts of natural caffeine. Caffeine use may lead to anxiety, irritability, nervousness and sleep disorders for some users.  However, most people who like the effects of caffeine, normally drink a cup or two of coffee a day which provides 100 to 200 mg of caffeine. Those who drink two or more cups of coffee may wish to take one less capsule of Diet Rx. For instance, if four capsules of Diet Rx normally works for you, take 3 capsules if you plan to drink 2 or more cups.

Diet Rx testimonials
I have been taking Diet Rx for one week now. I have noticed that I do not feel hungry. The biggest difference that I noticed though is no night time snacking. I never go to bed before 2:00am and usually start my evening snacking around 10:00pm I must clarify that what I call a "snack" other people call a meal. I am not fond of sweets so therefore my "snack" is something meaty (pork chop, chicken breast or steak) or a sandwich or two with all the trimmings. I have not even thought about having something to eat in the evenings since starting Diet Rx. I tried a diet pill once before in my life but did not like it because it gave me an awful nervous feeling and fast heart beat. I don't feel anything like that with this diet product. In one week I lost three pounds.

Testimonial
I find myself eating a lot less, with little desire for food. Before I was starving all the time. It surprises me that it lasts all day, including through the evening. I have lost a total of 7 lbs within two weeks. No side effects, no life style changes. This is wonderful. I am amazed how I do not think about "late night snacking" Wow.

Side effects, adverse reactions, safety
No major side effects have been reported when using one to three capsules a day. There could be excess energy when taking more than 3 or 4 capsules.

Interactions
I take Armour Thyroid for hypothyroidism. I have been taking it along with Diet Rx and don't feel any adverse effects.

Antidepressant medications
Is the product Diet Rx safe to take with antidepressant prescription drugs?
   A. There are many types of antidepressants and people are given different dosages and each person is unique hence it is difficult to give an answer that applies to everyone. If your doctor approves begin with one capsule to see how it goes and gradually increase to two and so on under medical supervision.

Use with contraception pills, birth control pills
Is it safe to take Diet Rx while taking a birth control pill?
   A. We have not had any such problems reported to us, but the safety of combining prescription medications and dietary supplements has to be decided by the consumer along with their health care provider.

Diabetes, high blood sugar
I have Type one diabetes and use an insulin pump. I also take Singular and baby aspirin. I want to start using maca for hot flashes and want to know if I could use Diet Rx as well. I would like to lose 10 to 15 lbs. I've gained some weight from the insulin pump and from menopause. I will discuss with my doctor and dietitian as well.
    A. It's best to be cautious and to learn how each supplement effects your body one at a time rather than combining them. It is not possible for us to predict how these natural supplements will influence you but, if your doctor approves, you could begin with one Diet Rx capsule a day. If you plan to use maca, take a break from the diet pill and use it alone for a week. If combining supplements, it is best to use low dosages to avoid any potential side effects. It is difficult to predict the interactions of various supplements and medications.

Statin drugs for cholesterol lowering
Q. Recently my doctor, Valerie Donaldson in Pittsburgh, recommended that I take Diet Rx. When reading more about the product I realized that it contains grapefruit extract. I am currently taking Lipitor. Is it safe to take while on Lipitor or other statin drugs used for cholesterol lowering?
   A. The amount of grapefruit extract in Diet Rx is quite small. When considering interactions between medications and supplements, one has to look at many factors including dosage, overall health of the patient, other medications used, age, activity level, diet, alcohol use, and many other factors that influence a person's overall health and medical status. Diet Rx can help curb appetite thus reducing food intake. It is possible that the required dosage of Lipitor may be less since cholesterol levels are influenced by the type and amount of food ingested. We can't be any more specific since each person's response may be different . You and your doctor would have to make the final decision.

Statins that are approved for use in the U.S. include: atorvastatin (Lipitor), fluvastatin (Lescol, Lescol XL), lovastatin (Mevacor, Altoprev), pravastatin (Pravachol), rosuvastatin (Crestor), simvastatin (Zocor), and. pitavastatin (Livalo).
