Some users of Curvelle have reported side effects that include upset stomach and jitteriness. Diet pills may contain ingredients that interact with other medications. If taking prescription drug or herbal medications, consult a medical professional for advice before taking Curvelle. Weight loss pills such as Curvelle are not FDA-approved for weight loss. Curvelle contains caffeine. Since caffeine is a stimulant, do not take Curvelle within 4 hours of sleeping. If taking Curvelle, reduce caffeine intake from other sources. Too much caffeine can cause nervousness, jittery feelings and heart palpitations.
What is Curvelle?
Curvelle is a fat burner designed specifically for women. Curvelle claims to control sugar cravings, burn excess calories and contain antioxidants to enhance health and radiance. Although the manufacturer claims that Curvelle is an effective fat burner and appetite suppressant, the ingredients do not appear particularly potent.

Curvelle ingredients
Curvelle contains a proprietary blend of 683 mg of ingredients that include:
Cinnulin PF: An extract from cinnamon bark that is believed to be able to balance the sugar levels in the bloodstream. Stabilization of insulin function is of great importance to slimmers. It is rapidly fluctuating blood sugar levels and the subsequent craving for sweet foods that hampers the efforts of many dieters. High doses of cinnamon have actually been demonstrated to be toxic, but Cinnulin PF has been tested clinically and shown to be safe to ingest daily.
Green tea: Contains caffeine that speeds up the body’s metabolic rate. The combination of green tea (standardized for caffeine and ECGC) and caffeine has been demonstrated to promote weight loss (Obes Res. 2005; 13: 1195-204). Users sensitive to caffeine could experience any of the following side effects: restlessness, irritability, sleeping problems, tremors, heart palpitations, loss of appetite, upset stomach, nausea, frequent urination and skin rash.
Razberi K: This compound is a ketone found in red raspberries. It is believed to help reduce body fat by decreasing dietary fat absorption in the small intestine, and stimulate increased production of the neurotransmitter norepinephrine which promotes the breakdown of fat stored in cells. There are no reported side effects in taking Razberi K.
Slow release natural caffeine: This variant of caffeine is incorporated in Curvelle. As good as this may be, dieters who are especially sensitive to caffeine should be careful when considering using Curvelle. This diet pill contains caffeine at a dosage equivalent to 3 cups of coffee. Excess caffeine may cause jitters, insomnia, headaches, increased heart rate and blood pressure.
Elderberry extract: This extract is rich in anthocyanins and antioxidants which have been shown to improve health and help fight oxidative stress in the body. There are no recognized adverse effects, although data is limited. It is suggested that a diuretic of elderberry extract may result in hypokalemia, but this has not been scientifically studied. There are no recognized drug interactions in taking elderberry extract. The stems, roots, unripe berries, and seeds may contain cyanide, and could cause vomiting and severe diarrhea if chewed or eaten uncooked. Ripe berries are safe when prepared for use in foods.
Curvelle dosage
Each container of Curvelle contains 100 capsules. Isotori, the manufacturers of this product, suggest taking two capsules before breakfast and lunch, as well as two before exercise.
There are several stimulants in the weight loss formula of the Fat Burner by Size 0 Labs. The caffeine, green coffee bean, green tea and Cha de Bugre all include stimulants that have been reported to cause jitters, headaches, nausea, stomach problems and other health issues in some users.

Size 0 ingredients
The relevant weight loss ingredients in Size 0 are as follows:
Caffeine anhydrous: This compound is a thermogenic agent with clinically proven benefits for weight loss. Caffeine may cause jitters, insomnia, headaches, increased heart rate and raised blood pressure.
Green tea extract: There is evidence to indicate that green tea offers benefits to dieters. Studies have shown that the tea can elevate metabolism and inhibit the action of the enzyme amalyse. Users sensitive to caffeine could experience any of the following side effects: restlessness, irritability, sleeping problems, tremors, heart palpitations, loss of appetite, upset stomach, nausea, frequent urination and skin rash.
Green Coffee Bean Extract: Coffee made from green, unroasted coffee beans has recently been found to promote weight loss. The discovery parallels earlier research on green tea. Green coffee appears to have a more potent effect. There are two key types of compounds in unroasted coffee beans. The first is caffeine and the second is chlorogenic acid and its related compounds. Heating destroys the acids. Currently, there are no clinical studies on green coffee extract’s weight loss effects on humans. In human trials, no significant adverse effects have been seen. In theory, the caffeine content of green coffee bean extract could potentially cause problems for some people. However, since the compound only contains about 10% caffeine by weight, a high daily dose contains no more than about 20% of the caffeine content of a strong cup of coffee. Maximum safe doses in pregnant or nursing women, young children, or people with liver or kidney disease have not yet been established.
Naringin Citrus Extract: A powerful bioflavanoid found in grapefruit, giving it its bitter flavor. Naringin works synergistically with other nutrients, increasing their bio-availability and extending their effects in the body. This citrus extract also interferes with enzyme activity in the intestines, and therefore can inhibit the breakdown of certain drugs. Naringin has been shown to be non-toxic at levels many times greater than the recommended dosages. Even when taken daily, naringin seldom produces a significant allergic reaction. However, people who are allergic to citrus fruits should exercise caution in the use of naringin.
Cordia Salisifolia Extract: This extract, also known as Cha de Bugre, is becoming a common ingredient in weight loss products and supplements. While no significant side effects have been reported Cha de Bugre does contain caffeine.
Also present is cocoa extract, probably included as a mood enhancer.
In addition to the thermogenic complex in Size 0, there are three additional complexes:
Appetite Support Complex: A blend of Hoodia gordonii, jojoba seed extract and Griffonia simplicifolia seed extract.
Beauty Support Blend: A blend of biotin, collagen, choline, horsetail leaf extract, hyaluronic acid, inositol, l-cycsteine, l-methionine, coenzyme Q10, silica, and chamomile flower leaf extract.
Estrogen Support Complex: A blend of chaste tree berry, daidzen, dong quai root and vitex agnus castus.
Size 0 recommended dosage
Each bottle of Size 0 contains 100 tablets As a dietary supplement, the manufacturers recommend taking 1-2 tablets, 2-3 times daily, 30 minutes before eating, with 16 oz of water. Begin use with a lower dose to assess tolerance.
