Nootropic supplements often contain caffeine as it boosts alertness and energy levels, despite it not being a ‘real’ nootropic ingredient, but they typically do not contain any stimulant ingredients that are stronger than caffeine. PowerFocus has bucked this trend, adding Citrus Aurantium, as well as three different sources of caffeine onto their already long ingredients list.

Below we take an in-depth look at PowerFocus to see whether it can improve memory, focus and concentration, as claimed by the manufacturers.

What You Need To Know About PowerFocus

PowerFocus is marketed as a nootropic supplement that will improve focus, memory and concentration. It may also boost mood. However, it also contains numerous ingredients that are more commonly found in weight loss supplements than nootropic supplements, which we believe have been included to boost energy levels significantly. These ingredients, including citrus aurantium, can cause a range of side effects, and mean that the product is a stimulant.

What Are The Side Effects Of PowerFocus?

With such a long ingredient list for PowerFocus, it is unsurprising that there is also a very long list of potential side effects. Side effects are not mentioned very often in customer reviews, but they do include headaches and feeling tired; one consumer found that the product did not work as advertised for them, stating, ‘it made me lethargic, tired, and unmotivated.’

A full list of the potential side effects that could develop whilst taking PowerFocus is available below, under the Side Effects tab.

How Much Does PowerFocus Cost?

Customers have debated heavily in their customer reviews whether or not PowerFocus is expensive in their view, and whether it is worth the financial investment; compared to other nootropic supplements, it is far from the cheapest available, with some other nootropic supplements costing half the price of PowerFocus.

A single bottle, containing a 30-day supply of capsules, costs £39.49 from both the official sales page and from Amazon. Discounts are available for purchasing in bulk from the official website as well.

Our Verdict On PowerFocus

Overall, we have a very mixed opinion about PowerFocus.

The product contains a long list of ingredients, including some that should help to improve the consumer’s memory and focus, as advertised. Other ingredients, however, are more controversial, such as the use of citrus aurantium. Citrus aurantium is a strong stimulant and whilst it will boost energy levels, it is likely to cause a crash in energy levels later in the day, and can cause side effects. The use of three different sources of caffeine, and three different sources of choline also seems unnecessary.

There is a 30-day money back guarantee on offer from the manufacturers, which covers purchases from amazon and from their official website.

Many of the customer reviews are not verified on amazon, often because the customer purchased from the official website. Customers are offered an incentive for writing a review – a full refund on their initial purchase! This deal may explain why there are so many unverified customer reviews; here we have mixed feelings, as it is a practice accepted by Amazon as long as customers put a disclaimer that they received some sort of discount. The company also stress numerous times that the review should be accurate and unbiased, which is better than some other companies we have seen, who will only reimburse customers for positive, 5-star reviews.

The product is relatively expensive, but does appear to be packed with active ingredients. However, as mentioned above, we dislike the balance of the ingredients, which feature more stimulants than we would like to see in a nootropic.

Overall, we do not recommend PowerFocus to our readers!

PowerFocus Review

PowerFocus is a nootropic supplement that is designed to improve memory, focus and concentration. The use of theanine and 5-HTP should also provide a mood boost, and the use of several stimulant ingredients, including three different ingredients that naturally contain caffeine should mean that consumers notice a significant boost in energy levels, both mental and physical.

PowerFocus Facts

  • Manufactured by Brainpower Nootropics
  • 60 capsules per bottle

PowerFocus is manufactured by Brainpower Nootropics, a company based in London, UK. The company can be contacted using the information found on their official website.

How to Take PowerFocus

Take two capsules per day with water. Take together or space them out depending on the strength of effect vs duration required. Do not exceed the recommended dose.

Although the official directions for use do not specify the times that the product should or should not be taken, we recommend avoiding taking the product in the evening, as it contains some naturally occurring caffeine and citrus aurantium, which are both stimulant ingredients that could interfere with sleep patterns.

PowerFocus Concerns:

  • Contains stimulant ingredients including Citrus Aurantium
  • Long list of potential side effects

What Does PowerFocus Claim To Do?

The manufacturers of Power state the following about the product and its benefits:

PowerFocus® has been scientifically evidenced to improve Focus, Memory, and Concentration. PowerFocus® is a premium cognitive enhancer that facilitates clear thought and lightning fast recall. It also provides a noticeable mood boost. It is vegetarian, Vegan and contains no Gluten-containing ingredients.

Does PowerFocus Work?

Some of the ingredients in PowerFocus have interesting preliminary support suggesting that they could aid various aspects of cognitive function. There are also numerous ingredients that could boost energy levels, but some of these (such as citrus aurantium) are seen much more often in weight loss supplements that nootropic supplements.

The doses required for various benefits can vary hugely; studies suggest that the dose of choline needed for improved memory is around 250 mg per day, whilst the dose needed for improved cognitive function in the elderly was four times that amount.

Bacopa Monnieri needs to be taken daily for an effect to build up over time, but some of the other ingredients could cause a general improvement in energy levels shortly after taking the supplement. Caffeine and Citrus Aurantium will both increase energy levels, both mentally and physically. Theanine should help to promote a calm but alert feeling, and may help to reduce the potential side effects of caffeine (but it may not reduce the side effects of Citrus Aurantium).

Choline could improve memory and cognitive function, depending upon the doses used. Bacopa Monnieri reduces anxiety and improves memory. Tyrosine could help to reduce fatigue, but appears to be used in inadequate doses here. A-GPC appears to improve cognition.

Overall, there are numerous ingredients that could, theoretically, help to boost memory and focus, both from the first few uses and over prolonged use. Immediately though, customers are more likely to notice the energy boost that comes from the caffeine-containing ingredients and the significant dose of citrus aurantium.

What Are The Ingredients of PowerFocus?

The ingredients found in PowerFocus are detailed below. The ingredient quantities listed are per serving of two capsules. The ingredients list on the back of the bottle states that the doses are ‘active mg’, which suggests that the actual quantities are smaller, but that the ingredients have been concentrated.

  • Guarana Extract 480 mg: A berry that is a good source of naturally occurring caffeine. 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.
  • Ginseng 320 mg: Korean or 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.
  • Bacopa Monnieri 300 mg: Used to reduce anxiety, improve memory, and seems to have a minor ability to treat depression, making it a general mild mood booster. Doses are typically larger than used in this diet pill, and effects can take time to achieve a noticeable level, as the effects appear to accumulate with repeated use.
  • Citrus Aurantium 250 mg: Citrus Aurantium, also known as bitter orange peel, naturally contains numerous stimulant compounds, including synephrine. A review of numerous studies concluded that use of synephrine resulted in an increase to the participants resting metabolic rate and energy expenditure, and moderate weight loss was seen in studies lasting over 6 weeks. However, there are some concerns about its safety being under-researched and the numerous side effects that have been associated with it.
  • Green Tea Extract 200 mg: Green tea is high in a group of antioxidants called catechins, and is also a natural source of caffeine. Studies have suggested that catechins increase thermogenesis in the body, whilst caffeine increases energy expenditure and energy levels by boosting the metabolism slightly for few hours.
  • Green Coffee Extract 200 mg: Contains caffeine. Whilst it was thought that this ingredient was a significant aid in weight loss, the relevant research has been discredited as it was fraudulent. Currently there is no evidence that it aids with weight loss more than any other source of caffeine.
  • Ginkgo Biloba Leaf Extract 200 mg: Some studies have found that gingko boosts memory and cognitive speed in healthy people, although other studies have failed to find this effect.
  • Choline Bitartrate 280 mg: Choline supplementation appears to improve attention, and could improve memory, although the dose was much higher than appears to be used here, and the relevant study focused upon the elderly. Choline is required to make increased levels of acetylcholine in the brain. Acetylcholine is a neurotransmitter which is linked with improved learning, memory retention and recall.
  • Choline Phosphatidyl 120 mg: Also known as Phosphatidylcholine, this has been found to improve memory in studies on mice with dementia.
  • L-Theanine 120 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.
  • Magnesium Citrate 106.66 mg
  • 5-HTP 80 mg: 5HTP is used by the body to make serotonin, which primarily plays a role in regulating mood. Some studies, primarily in animals, have shown that 5HTP reduces the appetite, as well as boosting mood.
  • Alpha GPC Choline 70 mg: In Europe alpha-GPC (also known as L-Alpha glycerylphosphorylcholine) is a prescription medication for the treatment of Alzheimer’s disease, but in the USA it is a prescription-free dietary supplement. It appears to have some cognitive-boosting properties, helps to prevent cognitive decline, and may also enhance power output in athletes.
  • Magnesium Stearate 60 mg
  • Ashwagandha Extract 60 mg: This plant is thought to lower cortisol levels in the brain and body. Cortisol is a hormone produced during moments of stress, which has been associated with increasing weight gain, and making weight loss more difficult.
  • L-Tyrosine 50 mg: An amino acid that is a building block of protein, this ingredient is found naturally in many foods including meat and dairy products. Some people use it as an appetite suppressant, but there is little 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.
  • Zinc 31.94 mg
  • Niacin 15 mg
  • Vitamin B5 7.76 mg
  • Vitamin B6 1.22 mg
  • Vitamin B12 0.4 mg

Does PowerFocus Have Any Side Effects?

There is an incredibly long list of ingredients that are used in PowerFocus, and many of these ingredients can cause a range of side effects.

Korean Ginseng can cause the consumer to have trouble sleeping. Other side effects from Korean Ginseng include changes in blood pressure, headaches, agitation, an upset stomach and dizziness. It is possible (but unusual) to be allergic to Korean Ginseng.

Side effects associated with the use of Citrus Aurantium including synephrine include increased heart rate and increased blood pressure, heart palpitations, fainting, and even heart attack and stroke in healthy patients. The Mayo Clinic has recommended avoiding use of synephrine and other Bitter Orange extracts because in their opinion, the risk of using the product is not worth the pay-off of any potential weight loss. The effects of synephrine and other bitter orange extracts are enhanced when combined with caffeine.

Caffeine is not present in this supplement as a separate ingredient, but it is naturally occurring in Guarana, Green Tea and Green Coffee Bean, three of the ingredients found in PowerFocus. Significant quantities of caffeine can cause side effects such as headaches, increased urination, dehydration, jitteriness, increased heart rate, increased blood pressure, heart palpitations and problems sleeping. Consumers should avoid other sources of caffeine whilst taking this supplement to avoid increasing the chances of side effects developing. Consumers should also stay hydrated by drinking plenty of water throughout the day, and should not take this product in the late afternoon or evening. These measures will minimise the chances of side effects occurring.

There is also an amino acid in Green Coffee Bean called homocysteine that is associated with an increased risk of heart disease. Green Tea can also cause constipation.

Theanine causes a state of relaxation without drowsiness, and may help to counteract some of the potential side effects of caffeine, such as jitteriness.

Studies have shown that Bacopa leaf causes upset stomachs in participants much more than placebos. This has led to the recommendation that this ingredient be taken with a meal, rather than on an empty stomach, as this will minimise the chances of getting an upset stomach. It may also cause nausea, cramping, bloating, and diarrhoea.

Ashwagandha can cause stomach upset, diarrhoea and vomiting, but is generally thought to be safe for short-term use.

Although Tyrosine is tolerated generally in very high doses, it can cause some side effects including nausea, headache, fatigue, heartburn, and joint pain.

Not suitable for anyone under the age of 18. Not suitable for pregnant or breastfeeding women. Not suitable for anyone sensitive to caffeine or other stimulants. Not suitable for anyone with any cardiac-related health issues, including but not limited to high blood pressure. If you are not sure about the suitability of this product. Consult a physician before using this product if you have any medical condition including, but not limited to, strokes, high or low blood pressure, heart, liver, kidney or thyroid disease, diabetes, anaemia, depression, anxiety, other psychiatric conditions, a family history of these or other medical conditions. Consult a physician before using this product if you are taking any prescription, over the counter and/or other herbal medications, including MAOIs (Monoamine Oxidase Inhibitor). Discontinue use and consult your doctor if any adverse reactions occur. Keep out of the reach of children.

Are There Any Customer Reviews For PowerFocus?

There are numerous customer reviews that have been left for PowerFocus, of which the majority are positive. Of the 74 reviews left on Amazon, only 11 are verified reviews. We believe that many of the customer reviews were left after they received a free product, as this is stated in many of the reviews. Although this does not automatically mean that the sellers are scamming customers, or that the reviews are fake, it does raise a lot of questions. In the question/answer section of the amazon sales page, the company have addressed one customer’s concerns about fake reviews, stating that none of the reviews are fake, and that ‘Nearly all sellers run offers where a product is offered at a discount in exchange for an unbiased review. This is a common practice allowed by Amazon who have their own review system called Amazon Vine. Reviewers are not paid or obligated to leave a good review.’

The company’s official website also states:

Reviews are really important at BrainpowerNootropics® – it allows us to see how we are performing and see where we can improve. Impartial feedback and reviews from people like you can help others make informed buying decisions. Existing customers can get a full refund by doing a YouTube video or blog post review.

Below are some of the verified reviews that were left by customers.

Not for me made me feel tired as hell and big headache.

Fast delivery. Have changed to this product from another and seems to work better for me! Shall buy again.

It’s expensive as it’s the best! I got recommended this by a friend and was a little apprehensive at first. Having had the product for a week, I can honestly say it’s working wonders. I work 80+ hours a week and was constantly tired, not focusing and generally being a little unproductive. I feel so different now I’m taking Power Focus and will continue to do so! Thanks guys!

I hate to be “that guy” but I nearly didn’t order because of the amount people were given free to write an “honest and non-biased review” which put me off as it all looks so fake, I’ve been using them a week nearly and it’s nothing like what everyone’s saying? I take two as told and notice no difference at all, just the horrid taste when I put them in my mouth… I’m going to give it longer to see and may change my review but until then it seems everyone’s definitely overhyped them after being given them, so take it with a pinch of salt.

Superb product, having tried it for 1 week whether it be coincidence or not but I really have felt a lot of improvement in my Concentration levels, Mood & Focus. I’ve recently started a new job and having taken these they really have helped me absorb all the new info I need to take on board and keep focused and ready for anything!!!
