I found the ingredients on a site that sells it. I've not seen the actual label, though, so you might compare this to your bottle.
Guarana (Natural caffeine): South American bean that boosts energy levels. The natural energizer!!
Bee Pollen: Boost energy and stamina.
Ginseng (root): Increases energy levels and reduces appetite.
Ginger (root): Ginger nutritionally supports the digestive process.
Lecithin: Lecithin is a natural source of choline and inositol, two members of the B-complex vitamins involved in protein and fat metabolism.
Damiana (leaf): A natural lift-me-up.
Sarsaparilla (root): A natural alternative for increasing energy, helping to regulate hormone balance and boost hormone production, muscle building, increasing metabolic rate and enhances glandular balance.
Golden Seal (aerial part): Golden Seal is one of the most potent herbal detoxifiers, it cleanses and enlivens the blood, lymph and tissues throughout the body
Nettles (leaf): Increases metabolic rate.
Gotu Kola (aerial part): Effective herbal energy booster thus enhancing metabolism of carbohydrates and fat.
Gymnema Sylvestre (aerial part): People in India have been using the Gymnema Herb as a sugar killer for centuries.
Gymnema sylvestre has been successful in controlling the blood sugar level without reducing it to below the normal blood sugar levels. Due to it's non-toxic nature and sweetness-suppression activity, Gymnema sylvestre plays a role in treating conditions caused by excessive sugar intake, such as obesity and hypoglycemia.
First, keep in mind that the claims made by these manufacturers do not have to be proven. They can say almost anything they want, as long as they don't claim to actually cure a disease or make similar medical statements. Therefore, they are going to tell us what they think we want to hear, in order to make a sale.
Second, keep in mind that since these products are not regulated, they may or may not contain what is on the label. Also, the dosages of any ingredients may not be enough to help a fly, or they may contain potentially dangerous amounts of some items. Dosages vary widely from pill to pill.
Another thing to remember is that products such as this frequently contain contaminants, such as lead or other dangerous ingredients.
Based on the ingredients, I see nothing that would be of benefit. Most of the items, and their claims, are based on unproven ideas or fads.
Guarana: Similar to caffeine, that is true. It will likely make you feel jittery, the way caffeine does.
Bee pollen: The claim that it increases energy dates back to the 70s, but has never been clinically proven. It appears that bee pollen may be useful to bees, but not humans. There are studies being conducted on various usages.
Ginsing: from the University of California, Berkeley:
...Claims, Benefits: Boosts energy and athletic performance; treats or cures a wide range of disorders, from the common cold to HIV infection and Alzheimer's disease.
...Bottom Line: Scientists are still largely in the dark about its medicinal benefits. As of yet, there's no consistent evidence to support the use of ginseng. It contains many active ingredients, and it's hard to know which of these elements are important. And what's actually in any product labeled ginseng can vary greatly—some products contain no ginseng at all.
Also, Ginseng may cause stomach discomfort, including diarrhea, nausea, vomiting, throat irritation or loss of appetite, especially after long-term use. Maybe this is why they added the Ginger.
Ginger: Many claim it helps relieve motion sickness, though the results of scientific studies are conflicting. I think their statement "nutritionally supports the digestive process
" is almost funny though.
Lecithin: A leftover fad from the 70s. According to Berkeley :"You would have to consume enormous amounts of lecithin to get the health benefits, if any. High doses can cause nausea, bloating, and diarrhea."
Damiana: Purported to be a natural viagra. I could not find any evidence it is useful for weight loss.
Sarsaparilla: I could not find any evidence it is useful for weight loss. However, it makes a good beverage, similar to root beer
Goldenseal: From Berkeley: "Potential side effects include stomach upset, nervous symptoms, depression, and (in large enough quantities) even death from respiratory failure. Pregnant and nursing women should avoid it; so should children, as well as anyone with elevated blood pressure, heart disease, epilepsy, or blood clotting problems. "
Gotu Kola: No evidence to support their claims. However, here is something interesting... From Intelihealth: "Gotu kola may raise blood sugar levels and may work against drugs that lower blood sugar levels. Patients taking oral drugs for diabetes or using insulin should be monitored closely by their health care provider while using gotu kola."
Maybe that's why they also include the next ingredient, which is supposed to lower blood sugar levels??
Gymnema Sylvestre : Yes, they were right about this one, evidence does show that it reduces blood sugar levels. This ingredient should be taken in specific dosages, but you'll never know how much is in Metabo Bio Slim.
It took a while to look up each of the ingredients in this product. I do this frequently, lol. But the results are always the same. These herbal products just aren't worth the money, and many can be potentially dangerous.
It's better to stick with a healthy diet and exercise program. This is the ONLY proven safe and effective way to successful and long term weight loss
