Thermoraw Raw One (Bioking Labs T5 Fat Burner)
When we were asked to review Bioking Labs T5 Fat Burner, we quickly realised that something strange had happened to the product’s name because it is now called Thermoraw T5 Fat Burner! These days, Bioking has transformed into Raw One and most references to the earlier company name have vanished. So let’s look at Thermoraw T5 Fat Burner, as this supplement is now called, and see if it is worth a try despite the change of identity!

Raw One is a supplement brand based in Tyne and Wear UK. There is no real information about this brand or the people behind it, and Thermoraw T5 Fat Burner only seems to be available to buy via Amazon and eBay UK.

Thermoraw Raw One Overview

What you need to know about Thermoraw Raw One

Thermoraw T5 Fat Burner is an updated name for a supplement that was called Bioking Labs T5 Fat Burner in 2018, but has since been changed. The company name has been changed too and instead of Bioking, the business name is now Raw One.

Thermoraw T5 Fat Burner is made in the UK and is touted as a T5 Fat Burner, but in truth, contains a variety of ingredients in fairly low quantities that are unlikely to work as described. Each bottle contains 90 capsules which are enough for a month’s supply.

You can still find this supplement advertised as Bioking Labs T5 Fat Burner on eBay and on Amazon France.

What are the side effects of Thermoraw Raw One?

Side effects are unlikely to be an issue for most users because ingredient quantities are low. However, if you are ultra sensitive to caffeine you may notice mild side effects including insomnia, jitteriness, headache, and increased anxiety.

African mango seed can sometimes cause feelings of bloating or mild stomach pain.

Other potential side effects may include nausea, vomiting, and allergic reaction.

In the case of side effects, cease use and take medical advice if necessary.

How much does Thermoraw Raw One cost?

Thermoraw T5 Fat Burner is quite expensive especially as it is probably not going to work. You can buy it from Amazon UK where it costs £19.97 for a bottle of 90 capsules (30 servings). Free delivery is not available unless you spend over £20.00 and you can make a 5% serving and save on postage with bulk orders.

You can also buy Thermoraw T5 Fat Burner via eBay, where it is currently on sale for £27.00 for a bottle of 90 capsules.

It is still on sale as Bioking labs T5 Fat Burner from some independent eBay sellers and via Amazon France.

Thermoraw Raw One Key Features

Thermoraw T5 Fat Burner is a weight loss supplement that contains a lot of well-known weight loss ingredients. These include glucomannan, caffeine, African mango extract, and more, and although many of these have nothing to do with fat burning, if used in the correct quantities, they may help weight loss.

A fat burner is a specific type of weight loss supplement that increases metabolism and body temperature. In addition, any supplement described as a T5 fat burner generally means that it contains something that is supposed to affect the thyroid hormones. Because the thyroid gland controls the speed of the body’s metabolism, the thinking is that increasing the thyroid hormones helps cause weight loss too.

Thermoraw Raw One Key Points

  • Used to be called Bioking Labs T5 Fat Burner
  • You can still find this supplement under the Bioking Labs name on eBay, and on sale from country-specific Amazon sites such as Amazon France
  • The principle ingredient is 100mg of glucomannan

Thermoraw T5 Fat Burner does contain bladderwrack – a type of seaweed that contains iodine, and as iodine is important for the thyroid gland, we guess this is the thinking behind the name. Check out the ingredients tab to find out more.

How to Take Thermoraw Raw One

  • Take 1 – 3 capsules daily with meals
  • Always drink plenty of water

The company name is provided as Raw One and the company address is provided as Marine Avenue Tyne and Wear. So we tried to check this out, but there was no background information and no mention of any business called Raw One or Bioking Labs. In addition, there is no official website in either name or even a Facebook page.

Thermoraw Raw One Concerns

  • Although this supplement looks fairly safe, some customers may experience unforeseen side effects
  • Zero background information to Bioking Labs or Raw One. There isn’t even a Facebook page for either name
  • The customer feedback on Amazon looks fake, according to scam software

Raw One does sell a couple of other supplements including a testosterone booster called Alpharaw, and a zinc and magnesium supplement called XMatrix6, but outside Amazon UK, it appears that this brand and this company does not exist!

Strangely on Amazon sites in Europe such as Amazon France, the old Bioking Labs name is still current.

What does Thermoraw Raw One claim to do?

According to the Amazon advertising,

“Raw One fat burner diet pills will help you lose weight by dramatically improving the rate in which body fat is burnt as well as providing a huge increase in explosive energy and focus levels. They provide remarkable results in combination with a healthy balanced diet.”

The key ingredients are advertised as:

  • GREEN COFFEE BEAN EXTRACT Supports fat burning and glucose metabolism via Chlorogenic Acids contained in decaffeinated Green Coffee Bean.
  • ACETYL-L-CARNITINE Supports performance levels while supporting utilization of fat for fuel during
  • AFRICAN MANGO EXTRACT helps reduce body fat, weight, and even cholesterol and leptin levels.

Other fat burning ingredients include:

“Raspberry fruit extract, L-Carnitine, Green Coffee Bean Extract, Caffeine Tartrate, African mango and other powerful ingredients for maximum weight loss.”

The supplement is manufactured in the UK, in accordance with good manufacturing practice.

Does Thermoraw Raw One work?

It seems unlikely. The ingredient quantities are low and there is nothing here that really marks this supplement out as a T5 Fat Burner, which usually tend to be very strong in stimulants. That said, Thermoraw T5 Fat Burner does contain Bladderwrack which is a source of iodine, but at this level, is unlikely to have any effect upon your thyroid hormones.

You may find that you lose weight if you combine this supplement with a diet and exercise program, but we can’t see it doing much beyond a possible placebo effect.

Thermoraw Raw One Ingredients

Serving size is equal to one capsule.

  • Glucomannan (100mg): Glucomannan is a natural fibre derived from the root of a plant called the Konjac. It is effective for weight loss because it is a natural appetite suppressant that works by filling the stomach with an absorbent gel, but it is only effective in the correct serving size which is around 3000mg a day. Source
  • Caffeine (83.34mg): Caffeine is a stimulant that most of us use on a daily basis. It can help increase the speed of the metabolism so help weight loss, but effects wear off as we become accustomed to use. Quantity here the same as just under one cup of instant coffee.
  • Acetyl-L-Carnitine (50mg): Amino acid that helps the body convert fat into energy and may help improve alertness and focus, although the serving size here is very low compared to other supplements on the market.
  • L-Tyrosine (50mg): Amino acid present in proteins including eggs and cheese. L Tyrosine can help improve energy levels and reduce stress if needed by the body, but it doesn’t seem to be effective otherwise. Serving size here is very low.
  • Raspberry Fruit Extract (Rubus idaeus) (fruit) (from 50mg of 10:1 extract) (50mg): There is only 50mg of fruit extract contained here, but because this is in an extract form, the makers suggest it is the equivalent of 500mg. This is fruit extract so may be of general benefit like all fruit, but this is not the same as a raspberry ketone supplement that uses only one specific plant phenol – the part of the plant that causes the aroma. Unlikely to have much if any effect.
  • Green Coffee Bean (Coffee L.) (fruit) (Standardised to contain 50% Chlorogenic Acid) of 40:1 extract) (25mg): There is only 25mg of green coffee bean extract contained here but because it is in extract form, the makers claim this is the equivalent of 1000mg. It won’t make much difference because green coffee bean has not been proven to help weight loss.
  • African Mango (Irvingia Gabonesis) (seeds) 10:1 extract (25mg): According to the condensed form used here, this is said to be the equivalent of 250mg. African Mango seed may have weight loss benefits because it is high in fibre so can help fill you up. Doing this may help leptin function, the hormone that signals when you have an empty stomach. However, as the main way this works is by the bulk of the fibre, we cannot see this extracted form having the same appetite reducing effect as was seen in the limited clinical testing.
  • Capsicum (Capsicum annuum) (fruit) (from 12.5mg of 8:1 extract) (100mg): Hot peppers make you feel hot so are a natural thermogenic when you eat them in hot spicy food. However, there is little evidence that this works in supplement form and it can cause gastric irritation.
  • Bladderwrack Extract (Fucus Vesiculosus) of 35:1 extract (5mg): This part of the formula is a type of seaweed and the makers say it is standardised to contain 1% iodine which adds up to

The body needs the mineral iodine for multiple uses including healthy thyroid function. The RDA for iodine is generally 150mcg, but you should be able to obtain your iodine requirements from diet (it is present in dairy products). Supplements should not exceed the RDA so this seems within safe guidelines. Source

  • Chromium Picolinate (66.67mcg): The type of chromium, a trace mineral, most commonly used in supplements. It may help the way the body uses insulin and can help control blood sugar levels in people with diabetes. Usual serving size is between 50mcg and 200mcg so this should be a safe serving, although there is no evidence it can promote weight loss.

Thermoraw Raw One Side Effects

Side effects should not be an issue for most users. Ingredient levels are low, so most people will be able to take this without any issues.

If you are ultra sensitive to caffeine, you may find it causes mild caffeine side effects such as insomnia and jitteriness, but we cannot see this being a problem for most users.

African mango seed can sometimes cause feelings of bloating or mild stomach pain.

Other side effects may include nausea, stomach irritation, and headaches.

Bladderwrack can cause an allergic reaction in some users.

Caution: Not suitable for individuals under 18. Avoid if you are pregnant or breastfeeding. Speak to your doctor before using supplements if you have an underlying health condition or are taking prescription medication. Cease use in the case of side effects and seek medical advice if necessary.

Thermoraw Raw One Customer Feedback

There are customer reviews left on Amazon, but according to scam software, many of these are fake.

This review was left back in 2018 when Raw One was still calling itself Bioking Labs in the UK,

Great value fat burners. I was looking for a tablet that would help boost my metabolism and give me more energy when I train after work and found Bioking’s product agrees with me. Looking forward to some lean results in the coming weeks.

Other positive reviews include,

My appetite is definitely less than before and my energy level has increased. I really like these pills. Will buy again.

I have been using the product for almost a week and it’s pretty impressive, my energy levels are up, I am more focused and I have noticed my cravings going. I like that this product is ‘made in UK’ and has natural ingredients. Will be buying more.

There are a couple of negative reviews,

So disappointing! Haven’t noticed a jot of difference. My appetite has not reduced!!! If anything it has increased!!!!! Dumped this product ~ DONT waste your money and your time!

Watchdog Verdict

We are not very impressed with Thermoraw T5 Fat Burner. This supplement seems to be poorly thought out, and although some of the ingredients such as glucomannan can be good for weight loss, the low ingredient quantities make it unlikely to work.

In addition, the name is misleading. T5 Fat Burners are usually supplements which contain a lot of stimulants and components that affect the thyroid gland, and although this one does contain iodine in the form of bladderwrack, the lack of functional stimulants makes it unlikely to work as implied. In a way, this is a good thing because T5 supplements often cause side effects, and it can be very risky to meddle with the thyroid gland by taking iodine. The downside of this supplement is that it may do nothing at all!

Thermoraw T5 Fat Burner is just not good enough to recommend to the Watchdog readers.
