Grilla Fitness Burn Bullets
Grilla Fitness Burn Bullets is a fat burner that claims to support metabolism and energy. It’s sold by an Essex-based fitness company, formed by TOWIE twins Dino and Georgio Georgiades.

Let’s take a look to see if it works or if it’s just a load of hype.

Grilla Fitness Burn Bullets Overview

What you need to know about Grilla Fitness Burn Bullets

Grilla Fitness Burn Bullets might aid weight loss in combination with diet and exercise. It is not expensive at £29.00 for one month’s supply (60 capsules) and will probably increase metabolism and decrease appetite as claimed. However, it is not suitable if you are taking prescription medication for health or mental health issues. There is no money-back guarantee and it is only on sale via the official website.

What are the side effects of Grilla Fitness Burn Bullets?

Grilla Fitness Burn Bullets may cause side effects. It was featured in the Daily Mirror after it caused a customer to be admitted to hospital with chest pains and breathing difficulties. Other side effects may include increased heart rate and blood pressure, headaches, nausea, jitteriness, and insomnia.

There are concerns about taking tryptophan in supplements. Adverse effects can include gastric issues such as heart burn, vomiting, and nausea. It can also cause mood swings, fatigue, and light headedness. Health experts actually warn against taking tryptophan in supplements because it is linked to causing a rare disease called eosinophilia-myalgia syndrome (EMS). It can interfere with prescription medication for mental health issues too. It is not suitable if you are taking selective serotonin reuptake inhibitors (SSRIs).

This supplement will also not be suitable if you are taking prescription medication because it contains naringin, a chemical derived from grapefruit. Grapefruit causes drug interactions with around 80 medicines.

How much does Grilla Fitness Burn Bullets cost?

Grilla Fitness Burn Bullets is not expensive – £29.99 for 60 capsules (one month’s supply). It also comes with a free diet plan.

Grilla Fitness Burn Bullets Key Features

Grilla Fitness Burn Bullets looks pretty good in general. The combination of green tea extract and caffeine is known to be effective for fat burning. There are some amino acids, such as L carnitine and tyrosine, which may improve energy. There is also chromium for regulating blood sugar levels.

Grilla Fitness Burn Bullets Key Points

  • Each bottle contains 60 capsules
  • Grilla Fitness is a British company owned by TOWIE stars Dino and Georgio Georgiades
  • Was featured in the national press after a customer was hospitalised

However, there are concerns about the formula. Burn Bullets contain Citrus aurentium – a strong stimulant which may cause side effects in some users.

There is also Naringin – a natural chemical contained in grapefruit, so you will need to check with your doctor before using if you are taking medication. Grapefruit is known for causing drug interactions and, although naringin may have benefits to health, it is not suitable for all.

How to Take Grilla Fitness Burn Bullets

Take one tablet twice a day. This is usually one in the morning and then one no later than 2pm, as for those who are sensitive to caffeine, taking Burn Bullets too late may affect sleep. Take around 20 minutes after you eat, with plenty of water. We suggest starting by taking one per day for a period of four days to assess your tolerance.

The final concern is with tryptophan. This natural amino acid is present in foods such as turkey and Brazil nuts. Once in the body, it converts to serotonin, the brain’s feel-good chemical. Although it is safe in food, in supplements it can cause side effects and is considered unsafe. Check out the ingredients tab and the side effects tab below for more information.

Grilla Fitness Burn Bullets Concerns:

  • Supplement may cause side effects
  • It is important to avoid this supplement if you are taking medication, but this is not made clear in the advertising
  • Shipping charges are not provided

Grilla Burn Bullets made the national press a few years ago when a girl was hospitalised after taking the tablets, following a possible allergic reaction. The company owners, TOWIE twins Dino and Georgio Georgiades, promised an investigation, but we don’t know whether or not this was resolved.

What does Grilla Fitness Burn Bullets claim to do?

There isn’t much in the way of real information, but the website does state:

Burn Bullets have helped thousands of customers towards their body goals. Constantly receiving great feedback along with amazing transformation pictures from our customers, it’s simple to see why Burn Bullets are so popular!

There are numerous before and after Instagram pics of satisfied posted on the official website too.

Does Grilla Fitness Burn Bullets work?

Yes, we think Grilla Fitness Burn Bullets should help support weight loss and the metabolism. The caffeine content (roughly the equivalent of 2 cups of coffee) paired with concentrated green tea will probably boost the metabolism and energy levels. The Citrus aurentium should add an additional stimulant kick and may help decrease appetite.

There are a few concerns. This supplement will not be suitable if you are taking prescription medication. In addition, tryptophan supplements can cause adverse side effects, including mental health issues.

Grilla Fitness Burn Bullets Ingredients

Serving size is equal to two capsules.

Vitamin B6 (2.8MG):

Here at 200% of daily required intake, B6 helps the body store and use protein and is important for the manufacture of haemoglobin. It also has an impact of mental function; low levels can lead to fatigue. The tolerable upper limit is 100mg, so not overly strong, and side effects should not be an issue. Source

Chromium (100µg):

A trace mineral, which means the body requires very little. Experts suggest that 30mcg is sufficient as a daily allowance – it is in numerous foodstuffs, including green veg, milk, meat, and eggs. Chromium plays a role in insulin production and the regulation of blood sugar levels. Taking a supplement may be helpful for people with type 2 diabetes. However, it does not seem effective for causing weight loss. The recommended upper limit is 1000mcg a day. Source

Caffeine (200mg):

Most diet supplements contain caffeine as it is ideal for giving you a quick energy boost. It can increase the speed of the metabolism and help fat burning, but the effects are often short-lived, as you become accustomed to use. When used in combination with green tea it may enhance the fat burning effect. A cup of instant coffee contains around 100mg of caffeine, so this serving size is the equivalent of just over two cups. Source

L-Carnitine Tartrate (200MG):

Carnitine is an amino acid found in most of the cells of the body. It is important for energy production and in helping your body burn, or oxidize, fat. Some evidence suggests that Carnitine Tartrate supplementation lowers glycogen usage – the sugar in muscles needed for energy.

L-Tyrosine (200MG):

Tyrosine is an amino acid made in body that helps the body convert fat into energy, as well as being important for mental functioning. N-acetyl-L-tyrosine helps the body make tyrosine, and in this form is especially beneficial for improving mental performance. Source

L-Tryptophan (100mg):

An essential amino acid, which means the body needs this, but is only obtained from dietary proteins such as turkey, salmon, meat, nuts, pulses, and eggs. L-Tryptophan is changed in the body to 5HTP (5-Hydroxytryptophan), a chemical that helps make serotonin, the brain’s feel-good chemical, so it is supposed to improve mood. There are some doubts about safety, as it was linked to causing a neurological disorder and it is known for causing other side effects.

Citrus Aurentium (100MG):

Also known as bitter orange peel, Citrus aurantium contains a chemical called synephrine, which has been proven to increase the metabolism. However, there are numerous concerns about its safety, especially as it increases heart rate and blood pressure if taken in high amounts. Source

Green Tea From 4:1 extract 400mg (100MG):

Although this is only 100mg, the extracted form makes it four times stronger. Green tea is the same as the ordinary tea we all drink but has undergone less processing during manufacture. This means it retains high levels of antioxidants called catechins and polyphenols. Polyphenols help prevent damage caused by free radicals – the rogue cells which lead to cell damage and disease. The main catechin is called EGCG or epigallocatechin gallate and is known to increase fat oxidation (fat burning), especially when combined with caffeine and exercise. Source

Naringin Extract (100mg):

Naringin is a natural chemical found in grapefruit. It may have health benefits and is undoubtedly rich in antioxidants, but is well-known for causing interactions with most prescription medication. If you are taking medication and are told to avoid grapefruit, you will need to avoid anything containing naringin too.

Bioperine® Black Pepper Extract (5mg):

Bioperine contains a chemical called Piperine that is present in black pepper. It helps increase bioavailability when used with other ingredients. Source

Watchdog Verdict

We have mixed feelings about Grilla Fitness Burn Bullets. The supplement does look effective and we think it will probably work for many people. Ingredient quantities – especially the green tea and caffeine – are effective, and although there are some health issues regarding Citrus aurentium, many people do find that this natural stimulant works to increase energy and decrease appetite.

However, there are some concerns. Grilla Fitness Burn Bullets contains tryptophan, which health experts recommend avoiding in supplements. In addition, the naringin content makes this fat burner a no-no for many users.

Other drawbacks include the lack of customer feedback, the reported story about a customer being hospitalised, and the lack of a money-back guarantee.
