How to Take Phentaslim

Take three capsules per day. The manufacturers do not state on the website how best to distribute these three capsules, but we suggest taking two with breakfast, and the third capsule either with lunch or about an hour before exercise. Because of the caffeine content, consumers should avoid taking this product in the evening. 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 describe the following benefits of the product:

  • Boost Metabolism – Ramp up your metabolism so that you burn more calories and promote fat loss.
  • Longer Lasting Energy – Boosts energy levels without that crash and burn feeling, so you’re ready for anything!
  • Suppress Appetite – easily suppress your appetite so that you stop snacking between meals and eat less!
  • 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 metabolism slightly for a period of a few hours after consumption. The caffeine 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 may help to counteract some of the potential side effects of caffeine, including jitters. The inclusion of black pepper extract will likely increase the absorption of caffeine, enhancing its effects and the likelihood of side 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 consumers who are very sensitive to caffeine, the dosages are well-balanced to be effective whilst making side effects relatively uncommon.

If you’re very sensitive to caffeine then this supplement may not be for you. Consumers unsure if they can tolerant the caffeine could try the recommended advice of starting with 1 capsule per day and avoiding other sources of caffeine such as coffee, tea and energy drinks. This will minimise the chances of side effects occurring.

Each capsule contains a similar amount of caffeine to a cup of coffee.

Consumers who are taking medication should consult their doctor before also more at risk of accidentally overdosing because of the higher absorption rate associated with bioperine, and so should consult with their doctor before taking this product. Theanine may help to counteract some of the potential side effects of caffeine, including jitters.

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 anyone who is sensitive to caffeine and other stimulants.

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 do get the stomach burning after taking, but a few sips of milk and it goes away!

I received my order in the mail super fast which was awesome. I’m sorry to say I have decided not to take them as I feel too spaced out and jittery on them. I will say though that I’m not a coffee drinker so I think it was due to the caffeine in the pills. I’m not giving a bad review they just aren’t for me. Best of luck to everyone!

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. However, I would recommend only taking a month or two course at a time before taking a few weeks break off of them (maybe to try out Superfruit Slim, which I have just started) as their effectiveness diminishes over time as your body gets used to them.

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 caffeine while taking this product, at first I continued to drink caffeine as normal and couldn’t sleep/was feeling a bit jittery. However when I cut the caffeine out 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 you must eat after the 20 min recommendation of taking them or you will experience slightly bad stomach pain 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. Without diet or exercise, these pills are just a waste of money. You put in the effort and these pills will help you get the most out of what you do. 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.

Side effects are unlikely unless you’re particularly sensitive to caffeine.

Watchdog Verdict

Overall, we are very impressed with both Phentaslim and its manufacturer, Optimum Nutra Inc. The company clearly associate themselves with their own products on their official website, provide a company address, and follow high manufacturing standards for diet pills. They offer a 60 day money back guarantee; the returns policy is clear and easy to follow and all the information available on the website. The claims the manufacturers make about the product are supported by references to clinical trials, and are not outrageous or ridiculous.

As for Phentaslim itself, it appears to have a solid ingredients profile, using appropriate dosages of the active ingredients. Numerous ingredients used in the product have strong clinical support, such as caffeine and green tea. The ingredients used also have a strong safety record, with side effects being unlikely in the doses provided in the product. That being said, customers should consider the cautionary guidelines before purchasing the product, and follow directions for use closely when taking the supplement.

It appears that the product has been around for quite a while and the number of positive reviews from happy customers around seem very encouraging. The customer reviews also support the idea that if used properly and alongside a healthy diet and regular exercise, Phentaslim can help to accelerate the consumer’s rate of weight loss. We recommend Phentaslim to our readers who are looking for an effective but safe metabolism boosting weight loss supplement.

    Is this drug like all the other pills that aim to mimic the effect of phentermine? I found that previous pills like thus gave me the worst migraine type headache and would be afraid of that happening again. Would be keen for the energy and motivation surge though !

  2. Alert Ferreira says:

    Is it available in South Africa, and if, where?

  3. Mike Watt says:

    I don’t know how much of my weight loss I can attribute to this pill but something I am doing is working.
    I was on a poor diet of pizza and different fried foods, lots of bread and potatoes etc. All the bad stuff!!
    I started on a diet of salads and soups, reducing my calorie intake. I increased my water intake to approximately 3 litres per day. I started excersising using Wii fit plus and saw my weight start to drop off. At the start of my program I was 101.8kg. Initially without the pills I lost 2kg in the first week but this stalled. I purchased 1 bottle of Phentaslim after trawling through tonnes of reviews looking for problems like side affects. I read some reviews saying about dizziness etc.
    I started with one tablet in the morning and one at lunch. I noticed an energy boost, I would put this down to the L-Carnatine and Caffeine.
    Phentaslim suggests 3 capsules per day. 1 at breakfast, 1 at lunch and 1 at dinner. I transitioned after 2 weeks to 2 at breakfast and 1 at lunch.
    So how much weight have I lost?
    I am currently at 90.4kg, so that’s almost 12kg in 1.5 months and I have just purchased two more bottles with the intention of reaching my ideal weight of 80kg.
    So I think these are contributing to my weight loss with no noticeable side affects. I see them as a slight helping hand when combined with a healthy diet and regular excersise.

  4. Ray says:

    I am vegan and would like to know if I opened up the capsule and had the powder with water, would this have any impact on the effectiveness of the pills?
    Thanks

    Hi what’s the name of site to buy from

  6. Nancy says:

    Do the reviewers of this product receive any financial gain from the products they recommend?

  7. Teri says:

    Does this company offer a similar product that doesn’t have the Cayenne Pepper? Over the past several years I have developed a gradually increasing allergy to spicy foods and we suspect it to be the capsaicin in many of the foods.

  8. Jacenta says:
