What Are The Ingredients of Phentaslim?

The ingredients used in Phentaslim are listed below. Each daily serving of three capsules contains a total of 1800 mg of the Phentaslim formula. The individual ingredient quantities provided below are per three capsule serving.

  • Green Tea (375 mg): Green tea is high in a group of antioxidants called catechins. Studies have suggested that catechins increase thermogenesis in the body, whilst caffeine increases energy expenditure by boosting the metabolism slightly for few hours.
    Source: http://ajcn.nutrition.org/content/70/6/1040.full
  • Caffeine (270 mg): Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism. The effects shown in studies are small, and some studies are inconclusive.
    Source: http://www.mayoclinic.org/healthy-living/weight-loss/expert-answers/caffeine/faq-20058459
  • L-Theanine (225 mg): This amino acid may play a small role in weight loss, as well as increasing feelings of relaxation. It may also reduce the negative side effects of caffeine, although there is seemingly no strong clinical evidence to support this claim.
    Source: http://healthyliving.azcentral.com/ltheanine-weight-loss-6800.html
  • L-Carnitine (200 mg): There is some evidence that supplementation of acetyl-l-carnitine can reduce body fat, although the strongest results were seen in the elderly. The ingredient also boosts energy levels, and is used to treat fatigue.
    Source: http://examine.com/supplements/L-Carnitine/
  • L-Tyrosine (200 mg): Some people use Tyrosine as an appetite suppressant, but there is little clinical evidence that it is effective for this use. Large doses of tyrosine may be useful for increasing alertness, especially in people who are sleep deprived.
    Source: http://www.webmd.com/vitamins-supplements/ingredientmono-1037-TYROSINE.aspx?activeIngredientId=1037&activeIngredientName=TYROSINE
  • Panax Ginseng (120 mg): Panax Ginseng is associated with improved cognition in fatigued subjects and slight decreases in muscle damage after exercise. It also appears to reduce fatigue, and consumers report feeling calmer after consumption.
    Source: http://examine.com/supplements/panax-ginseng/
  • Guarana Seed (100 mg): A berry that is naturally high in caffeine, it is often an ingredient in energy drinks and diet pills.
    Source: http://en.wikipedia.org/wiki/Guarana#Other_uses_and_side_effects
  • Magnesium (80 mg)
  • Cayenne Pepper (50 mg): Capsaicin, which is found in Cayenne pepper, is thought by some to play a role in weight loss. Some studies suggest it could suppress the appetite mildly, whilst others suggest that the heat causes a thermogenic reaction in the body, burning more calories for a period of time. However, there are also studies that show cayenne has little or no effect upon weight loss attempts.

  • Niacin (20 mg): Vitamin B3, or Niacin, is responsible for helping to produce energy from consumed food, as well as helping keep the nervous and digestive systems healthy. Niacin can be easily sourced in adequate amounts from a balanced diet. Persistent excessive consumption of niacin has been linked with increased rates of obesity in American Children.
    Source: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2874142/
  • Zinc (15 mg)
  • Black Pepper Extract (6 mg): Black pepper extract (piperine) is used for increasing the bioavailability of nutritional compounds. In other words, it increases the amounts of nutrients that are absorbed into the body in the digestive tract. It may also increase the absorption of various drugs, which may lead to potential side effects.
    Source: http://bioperine.com
  • Vitamin B6 (1.8 mg): Vitamin B6 has several important functions in the body, including ‘allowing the body to use and store energy from protein and carbohydrates in food’. Whilst taking excess amounts of vitamin B6 will not infinitely improve this ability, a deficiency could make it more difficult to lose weight.
    Source: http://www.nhs.uk/Conditions/vitamins-minerals/Pages/Vitamin-B.aspx
  • Vitamin B2 (1.7 mg): This vitamin is used for keeping the eyes, skin and nervous system healthy, as well as helping the body to release energy from carbohydrates. It is naturally present in milk, eggs, rice and fortified breakfast cereals, and so people should be able to get their daily guideline amounts from a healthy balanced diet.
    Source: http://www.nhs.uk/Conditions/vitamins-minerals/Pages/Vitamin-B.aspx
  • Thiamin (Vitamin B1) (1.3 mg): The NHS states that thiamine is important for helping to break down and release energy from food. This may be relevant for maintaining a healthy metabolic rate, but in the majority of cases people can obtain all the thiamine they require from their daily diet.
    Source: http://www.nhs.uk/Conditions/vitamins-minerals/Pages/Vitamin-B.aspx
  • Vitamin B12 (10 mcg): Vitamin B12 is naturally present in many foods, primarily meat, fish and dairy products. It has several roles, including aiding in releasing energy from consumed food, and keeping the nervous system healthy. It may be that a deficiency hinders weight loss, but taking excess amounts could be, according to the NHS, potentially harmful.
