One XS Review – Claims to be the best diet pill!

One XS reviewOne XS is a diet pill manufactured by Young You International and sold with promises of fast weight loss and boosted energy levels.

It is (at time of review) one of the searched for diet pills on

The company states One XS has helped thousands of people to lose weight, and makes a number of other bold claims claims for product:

  • Voted the strongest weight loss supplement on the market.
  • One of the safest and most powerful weight loss supplements on the market.
  • Helped thousands to lose weight.
  • Lose 20-25 pounds per month.

Claims:  To be the best diet pill !

Positives: Does include several of todays most effective and researched ingredients

Negatives: Wether they are the correct quantities is another matter!

Although all of this sounds very good, Young You do not supply any evidence to back up any of the things they say and the company’s reputation is somewhat questionable because, in 2009, FDA inspectors discovered four of the company’s products contained an undeclared weight loss drug (Sibutramine) that has been linked to dangerous side effects.

Method of Action – How It Works

One XS is a combined appetite suppressant and fat burner that has also been designed to boost energy levels. If the pills work in the intended way they should be able to support weight loss by helping the user to lower his or her calorie intake while also ensuring the body burns more calories than normal and begins burning its stores of fat.

In theory the formulation should also help prevent diet-related fatigue by providing extra energy. However, as is always the case with diet supplements, good results will only be obtained if the formulation contains ingredients that are capable of providing them. The ingredients will also need to be included in sufficient quantity without being diluted with binders or fillers.

Key Ingredients

  • Caffeine (200mg): Caffeine is renowned for its energy-giving abilities, can provide appetite suppression, and is also a scientifically proven metabolism booster.
  • Green Coffee Bean (175mg): Green coffee bean extract has shown a certain amount of prowess as an appetite suppressant, but the ingredient is more highly regarded for its abilities as a fat burner. Research has revealed the secret of the green bean’s power is a compound called chlorogenic acid. All coffee beans contain chlorogenic acid, but it is usually lost during the roasting process that is normally used to bring out their flavour.
  • Yohimbe 8% (150mg): An ingredient derived from the bark of the yohimbe tree. It has a long history of use as an aphrodisiac, and is also credited with many other abilities, including fat burning, but it has never been proven to be capable of doing so and, according to WebMD, it’s use may entail side effects.
  • Garcinia Cambogia 60% (100mg): An extract derived from the skin of a tropical fruit. The active ingredient in garcinia cambogia is hydroxycitric acid (HCA). It has an outstanding reputation for supporting safe weight loss and results are achieved thanks to HCA’s ability to suppress the appetite and interfere with the body’s ability to create fresh fat cells. However, although the garcinia cambogia used here contains the recommended amount of HCA (60%), 100mg per day is much too low. Most experts suggest a dose of 500mg, taken 3 times per day.
  • Aloe Ferox (5mg): A plant extract that is sometimes used as a treatment for sunburn, cold sores, and certain other maladies of the skin, but is not generally used as an ingredient in weight loss supplements.
  • Guarana (5mg): An extract taken from a berry that is high caffeine. Guarana has an advantage over other caffeine-providers because it releases its caffeine content at a slow and steady rate, thereby ensuring longer-lasting benefits.
  • L-Carnitine (5mg): An amino acid that is often used as a fat burning ingredient and may also be able to delay the onset of fatigue.
  • Citrus Aurantium (5mg): An ingredient derived from a species of citrus fruit. A scientific review of several human studies suggests the synephrine provided by citrus aurantium can support weight loss, but the amount included here is probably too low to be effective.
Usage Guidelines – one capsule is required, once per day, and should be consumed each morning with a glass of water.
