KOR Fat Burner for Men Overview

What You Need To Know About KOR Fat Burner for Men

KOR Fat Burner for Men is a weight loss supplement that claims to burn fat and give dieters a burst of energy. It provides customers with a long list of stimulant ingredients mixed with natural herbs that supposedly induce weight loss.

What Are The Side Effects Of KOR Fat Burner for Men?

Like most stimulant-based fat burners, this product can cause jitters, heart palpitations, headaches, stomach aches, sleeplessness, and other ailments. Some of its key ingredients, like synephrine, have actually been linked with more worrying conditions like heart attacks or strokes. This product carries with it a relatively high risk of side effects.

How Much Does KOR Fat Burner for Men Cost?

On all websites where it is sold, a 30-day supply of KOR Night Time (containing 60 capsules) costs $39.95 plus $3.95 in shipping. Buying in bulk can provide customers with a few savings on the official KOR Naturals website – a 2-month supply costs $79.90 and a 3-month supply costs $119.85 (both with free shipping).

Our Verdict On KOR Fat Burner for Men

This product packs in the usual ingredients we associate with fat burners, including caffeine, synephrine, green tea, bioperine, and garcinia cambogia. Normally, we would expect this set of ingredients to do the job (albeit with a host of side effects). However, this product appears to be far worse than most of its competitors at getting the basics right.

KOR Naturals have a bit of a reputation for poor quality and Fat Burner for Men is yet another offender. The few customer reviews we were able to find were generally negative in tone, with most claiming to have failed to lose weight or even gained weight whilst using the product. This is frankly not expected given the ingredients the product supposedly uses – we can only conclude that the manufacturer has formulated the product in a bad and ineffective way.

In addition, KOR Naturals makes it hard to view basic information about the product online, including the ingredients. Fat Burner for Men is also not cheap at $40 per month, making this poor value for money given the low success rate of customers using it.

You’ll be able to find near-identical products almost anywhere on the Internet, and almost all of those that you’re likely to find are better than KOR Fat Burner for Men.

We do not recommend KOR Fat Burner for Men to our readers.

KOR Fat Burner for Men Key Features

KOR Fat Burner for Men is a weight loss supplement that claims to act as a “powerful thermogenic fat burner”. As with all KOR products, this supplement comes in the form of red capsules that customers are instructed to take daily. Although the normal recommended serving is 2 capsules per day, customers are told that they can take an extra 2 capsules in the afternoon “if needed”.

KOR Fat Burner for Men Facts

  • Manufactured by KOR Naturals (a subsidiary of Synergistic Nutritional Compounds)
  • Contains 60 capsules per bottle
  • Weight loss supplement that claims to burn fat and give a burst of energy

Fat Burner for Men is manufactured by KOR Naturals, which is a brand owned and operated by a Utah company called Synergistic Nutritional Compounds LLC. There is little to say about KOR Naturals, as they only sell a handful of highly-similar products online, most of which appear to attract very little interest or customer enthusiasm. On Amazon, most KOR Naturals products appear to invite a lot of poor reviews, and the brand does not seem to be one that is associated with quality. The company can be contacted by telephone (888-879-9943) or via the contact form provided on their official website.

How to Take KOR Fat Burner for Men

The directions for use are as follows:

  • As a dietary supplement, take up to eight (8) weeks before discontinuing for a minimum of four (4) weeks. Drink plenty of water throughout the day to avoid dehydration. Make sure to allow at least six hours between servings. MORNING: Take two (2) capsules MID-AFTERNOON: If needed, take two (2) capsules.

KOR Fat Burner for Men Concerns:

  • The few customer reviews available are negative
  • May cause side effects
  • Manufacturer does not make it easy for customers to view ingredients online

What Does KOR Fat Burner for Men Claim To Do?

KOR Fat Burner for Men does what it says on the tin, claiming to act as a thermogenic, fat-burning weight loss supplement. On the product pages promoting it, Fat Burner for Men also claims to increase energy, prevent muscle loss, and target belly fat.

The manufacturers also state that some of the ingredients found in this product curb cravings, improve gym performance, decrease tiredness/fatigue, enhance mood/confidence, boost focus, and improve cholesterol and blood sugar levels.

Does KOR Fat Burner for Men Work?

Whilst looking at the ingredients, we would expect this product to work relatively well at burning fat, providing energy, and inducing weight loss (albeit at the cost of a host of side effects).

However, most customer reviews have stated that this product does little to nothing. Unfortunately, KOR Naturals appear to have a poor reputation for actually making high-quality products that customers like – so although it may look good enough at first glance, KOR Fat Burner for Men seems to be badly put-together and ineffective.

What Are The Ingredients of KOR Fat Burner for Men?

The ingredients found in KOR Fat Burner for Men are listed below. The quantities listed are correct for 2 capsules.

  • Vitamin B6 (as Pyridoxine HCl) 40mg (2353% DV): 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
  • Vitamin B12 (as Methylcobalamin) 300mcg (12500% DV): 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 will not correct this, as levels above the RDA are often just urinated out. Source
  • Garcinia Cambogia (60% HCA) 500mg: Test tube and animal research suggest that HCA, the active compound in Garcinia Cambogia, may be helpful in weight loss because of its effects on metabolism. However, numerous studies in humans have found it has no effect upon either appetite or metabolic rate. Source
  • Green Tea (4:1 Extract) 250mg: Studies have suggested that the EGCGs found in green tea increase energy expenditure by boosting the metabolism temporarily. However, the metabolic increase caused by these catechins is limited. One study found that the use of green tea was not enough to counteract weight gain following a high-calorie diet. Source
  • Caffeine Anhydrous 200mg: Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism (although the weight loss effects shown in studies are small, and some studies are inconclusive). The extra energy provided by caffeine could help to improve athletic performance. Source
  • Theacrine (as TeaCrine) 50mg: TeaCrine is a branded form of Theacrine. It appears to work in a similar way to caffeine. Early research suggests that it may help to boost mental and physical performance (like caffeine), but a little more research is needed to confirm this effect. It has never been linked with weight loss or fat burning specifically. Source
  • Higenamine 40mg: This chemical compound can be extracted from various plants. It has only been tested in vitro and in animals, so its effects in humans are totally unknown. However, these studies have indicated that it may aid athletic performance as a stimulant. Source
  • Theobromine 35mg: Theobromine is a mild stimulant that is similar to caffeine, but it appears to be much milder than caffeine. Source
  • Advantra-Z (30% synephrine) 25mg: Bitter orange peel has been proven to raise the metabolism and aid weight loss. It contains numerous stimulant compounds, including synephrine. A review of numerous studies concluded that the 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. Source
  • BioPerine (Black Pepper Extract) 5mg: This patented Black pepper extract 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
  • Yohimbine HCl 2mg: Some studies have noticed increased blood concentrations of free fatty acids in participants who use yohimbine extract, suggesting increased rates of lipolysis. However, the Natural Medicines Comprehensive Database has stated that there is insufficient evidence to claim it aids in weight loss. Source

Does KOR Fat Burner for Men Have Any Side Effects?

This heady mix of stimulants is likely to cause side effects.

The combination of bitter orange peel, bioperine, and caffeine used by this product is known for its habit of causing side effects. Potential adverse effects include heart palpitations, high blood pressure, jitters, sleeplessness, headaches, and irritability. It’s worth taking these risks seriously – bitter orange peel has actually been linked with the onset of strokes and heart attacks in otherwise healthy patients.

Yohimbe can also cause a wide range of side effects, including stomach upset, excitation, tremor, sleep problems, anxiety or agitation, high blood pressure, a racing heartbeat, dizziness, drooling, sinus pain, irritability, headache, frequent urination, bloating, rash, nausea, and vomiting. High doses can cause more severe effects.

Bioperine increases the bioavailability of other compounds, including caffeine and some medications; this could increase the chances of side effects from the other ingredients found in the product, or from caffeine consumed from other sources (tea, coffee, etc). Garcinia Cambogia can cause some side effects including nausea, digestive tract discomfort, and headache.

One final concern is that the formula uses a needlessly high dose of Vitamin B6 – although this ingredient is not thought to be harmful in normal circumstances, such a large quantity can cause flushing, brain and nerve problems, vomiting, loss of appetite, headaches, tingling, and sleepiness.

Not suitable for pregnant or breastfeeding women. Not suitable for anyone under the age of 18. If you are taking any medications or are unsure about the suitability of this supplement for you, consult your doctor before purchase.

I did not feel any “kick” from this product.

I bought this for my husband and he has not dropped a pound and is still fat. Does nothing. Waste of my money.

This supplement was worthless. Actually gained weight while taking these pills and that was with exercise (one hour on the treadmill on a 15% incline, 4 miles a day six days a week with a clean diet). Tried this supplement for nearly a month. Don’t listen to the other reviews, the reviewers are being paid to give this product good ratings. Useless!

Very good product and excellent seller.

worked ok.
