How to Take Phentaslim

Take three capsules per day.

Customers may also want to start with a lower dosage to assess personal tolerance levels.

What Does Phentaslim Claim To Do?

The manufacturer of Phentaslim describes the following benefits for the product:

  • Boost Metabolism – Ramp up your metabolism so that you burn more calories and promote your fat loss.
  • Longer Lasting Energy – Boosts energy levels without that crash and burn feeling, so you’re ready for anything!
  • Suppress Appetite – Suppresses your appetite so that you stop snacking between meals
  • Support Mental Performance – Supports good mental balance, good concentration and co-ordination.

So What Is Phentaslim and What Are The Ingredients For 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.

So What Does All This Mean?

Whilst many diet pill manufacturers offer statements and make dramatic claims about how their product works to aid weight loss, very few offer evidence for their claims. The manufacturers of Phentaslim have included numerous links to the clinical trials they have referenced.

Holding Phentaslim bottleCaffeine will increase the bodies metabolism for a period of a few hours after consumption. The content for each capsule is about the same as a cup of coffee, and so spacing out the doses, taking two with breakfast and one with lunch or before exercise will maximise the energy boost and metabolism boost throughout the day. Theanine will help to counteract some of the “jitters” a few people experience. The inclusion of black pepper extract will likely increase the absorption of caffeine, enhancing its effects.

Green tea and cayenne pepper will both increase thermogenesis in the body, burning more calories in the process. Cayenne pepper may also have a small appetite suppressing effect, although studies suggest that this is small.

Acetyl-L-Carnitine and Tyrosine are both amino acids, and so can be used by the body to create muscle mass when the consumer is under-taking muscle building exercises.

The vitamins provided in this supplement are of an appropriate level compared to the recommended daily intake. Consumers should ideally not combine this product with other sources of caffeine or other B vitamin supplements.

Does Phentaslim Have Any Side Effects?

Whilst some of the ingredients used in Phentaslim can cause side effects in a very few consumers who are very sensitive to caffeine, the dosages are well-balanced to be effective whilst making side effects uncommon.

As with anyone who is taking prescription medication, you should consult your doctor before taking a product of this type. Theanine claims to help to counteract some of the potential side effects of caffeine, including any jitters.

Caution:

Always swallow the capsules with water. Do not take if pregnant or nursing. If you have any medical conditions or are taking any medication, consult your doctor before use. Not suitable for anyone suffering from any heart related health issues, including but not limited to high blood pressure. Not suitable for those under the age of 18.

Any Phentaslim Reviews From Customers?

Numerous customers have left their feedback for Phentaslim here at Diet Pills Watchdog. A selection of these comments are below:

Started taking 1 of these each morning on Wed this week and am down 2 pounds already! Has given me the ability to get out of recliner and be the wife and grandmother Ive always wanted to be! Spotlessly clean house and flowerbeds are weeded. Been to the gym every day since starting these! Has really helped with my hunger and curbed appetite. I pray they continue to help like this!

I received my order in the mail super fast which was awesome. Best of luck to everyone who takes these, they’re great!

So after a full two month course on these pills, I am very happy to announce that I have lost two and a half stone in two months! I would recommend these to anyone hoping to get a head start on their weight loss as the extended energy, fuller feeling of stomach and ease of use make these HIGHLY commendable.

I ordered this product mid-April and am really liking it so far! Have lost noticeable weight (that people comment on). I do exercise regularly anyway so haven’t changed anything there, it’s just given me a much needed boost. The only thing I will say is that – as a big caffeine drinker myself – do not drink coffee while taking this product, at first I couldn’t sleep/was feeling a bit jittery. However when I cut the coffee down that all stopped! Good product if taken correctly!

Two weeks ago I was 20st 11.4lbs. Weighing this morning I am 19 st 11.6lbs. 0.2 pounds away from losing a stone in two weeks.
I have drank only water and eaten clean over the two weeks. The pills are amazing for helping to suppress your appetite but I recommend you have a small amount to eat after the 20 min recommendation of taking them or you will experience a weird stomach until some food is digested. The energy I am experiencing from these pills has really helped me down the gym and has finally kicked me into gear for losing weight. I highly recommend these pills for helping towards your overall diet and exercise plan but that’s all it is. A booster for your diet and exercise. You put in the effort and these pills will help you get the most out of what you do. 9.9/10.

So Does Phentaslim Work?

Both the ingredients list and the customer reviews we have located suggest that Phentaslim does aid weight loss without the side effects seen in other supplements.

Appetite suppression seems to be very effective for many consumers too, meaning this could help you to stick to a lower calorie diet plan you may be following.

  9. Louise wallis says:

    Hi how many capsules are there in a bottle please

  10. sharon says:

    Morning, I have high blood pressure (and am on medication for it) I am also diabetic (type 2 and take metformin) would I be able to take phentaslim *

    1. Edward Dergosits says:

      Metformin has come under great scrutiny and many doctors no longer prescribe it. Ask your doctor about this as soon as possible. Also do a web search before you see your doctor so you can ask questions pertinent to your situation.

      1. Gina Elliott says:

        Totally agree, Metformin is not the drug to be taking for Type 2 Diabetes….Diabetics have a 65% greater chance of getting Alzheimer’s than the general public. This common use of Metformin by diabetics, is the reason, since studies show any shortage of B12 has a big effect on the prevention of Alzheimer’s.
        Supplementing with standard oral B12 vitamins other then shots does not seem to be able to make up for the Metformin caused shortage.
        We suggest you learn to control your blood sugar without prescriptions…

  11. Catherine says:

    I think there’s at least one typo in the section on pricing. You mention “massive savings” but then say one bottle costs £37, two costs £77 (which is more than two single bottles) and four bottles cost £117, which does represent a saving per bottle of just over £7, which is admittedly 20%. Perhaps check the cost of two bottles?

    1. Bert Llamas says:

      I believe 1 bottle is quoted at 39 not 37.

  12. Vicky says:

    I don’t mean to sound rude but are these pills for really over weight people only ? I’m 9 stone which I know is not over weight but I used to be 8 stone & would love to get back down yo that weight. Will these pills work for me ? Anyone tried them who is same size as me ? & good luck everyone hope they work for you I’m really keen to try but don’t want to waste my money if they only work best for larger people

    1. Aly says:

      Heya! I’m in the same boat as you – it’s honestly a case of, just make sure your diet is correct, you’re getting the right amount of nutrients and food in you (ensure it’s a deficit you can maintain) then go from there 🙂 I would say along with working out, you’ll be back down in no time.
