Shinya Koso Diet Review – Comments and Side Effects

Shinya KosoShinya Koso Night Diet is a food supplement made in Japan. According to the marketing material it was developed by the noted surgeon and author Hiromi Shinya.

We were unable to find any evidence to support this claim, but Shinya often promotes the health benefits of enzymes in food, and the main ingredient in Shinya Koso Night Diet is a food enzyme called Nattokinase, so there could be some truth in the claim.

However many of the other claims made for the product border on the ridiculous. In fact, according to the box, each tablet can boost the metabolism so much it will burn the same amount of a calories that would normally be provided by 10.4 bowls of rice, 20g of sugar, 68.7 pints of beer, and 6 pieces of cake.

Other claims include:

  • Powerfully absorbs excess fat
  • helps control your weight (even after a late night meal)

How the Shinya Koso is Designed to Work

If the tablets can successfully power-up the metabolism in the promised way (highly unlikely), the metabolism will become so rapid it will start burning calories at an incredibly fast rate and use up all the calories provided by food.

This will cause a shortage of calories that will result in an energy shortage within the body. In a situation such as this the body responds by releasing the calories stored in its fat and uses them as an alternative source of energy. This reduces the amount of fat in the body, leading to weight loss.

Shinya Koso

The claim that Shinya Koso Night Diet can powerfully absorb excess fat is rather confusing. It may mean the tablets are intended to absorb dietary fats and block their absorption, but the formulation does not contain any recognized fat binding ingredients. But nor does it contain ingredients that have a reputation for boosting the metabolism.

Key Ingredients and Blend Potential

  • Nattokinase: This somewhat of an unusual ingredient because it’s sourced from a Japanese dish called natto. It provides an enzyme that that speeds up biochemical reactions, and is believed to be good for the cardiovascular system, but it does not effect the metabolism or assist weight loss.
  • Fish Collagen: A compound that is often credited with anti-ageing properties and may also help wounds heal faster, but is not capable of supporting any of the claims made for Shinya Koso Night Diet.
  • Chondroitin: A substance that is found in the bodies of animals and people and is especially abundant in the cartilage around the joints. It is often used for treating osteoarthritis, but is neither a metabolism booster nor a fat burner.
  • Hyaluronic Acid: A compound that is naturally-occurring in the fluids around the eyes and the tissues around the joints. It can also be sourced from roosters and this is the form that is generally used as a supplement ingredient. Hyaluaronic acid has a number of uses and is often used as a dermal filler, but it is unlikely to boost the metabolism or encourage weight loss.
  • Vegetable Lactic Acid: Lactic acid occurs naturally in milk, but is not normally associated with vegetables, so it is unclear what this ingredient is.
Usage Directions – One tablet is required each day, after a “late meal”. No further usage guidelines are provided.

Shinya Koso Side Effects & Health Considerations

The possibility of side effects is not mentioned in the Shinya Koso Night Diet marketing material, but the product is unlikely to be a safe option for women who are pregnant or nursing a child. Anyone who has existing health issues or is using medication should always check with a doctor prior to using any brand of dietary supplement.

Where to Buy Shinya Koso Night Diet

There does not appear to be an official website, but Shinya Koso Night Diet is available via a number of Asian online stores including The Takaski price is $28 for a 30-day supply of pills.


Shinya Koso Night Diet is sold without a money back guarantee.

The Verdict

Can Shinya Koso Night Diet really assist weight loss? We doubt it very much because, like all dietary products, its ability to sink or swim will depend on the abilities of the active ingredients and, in this case, none of the ingredients have the ability to do the things the product is professed to do.

The presence of Nattokinase may give the tablets value in other areas, but if you are looking for a good diet pill you would be better off seeking out something else.

Silvets Diet Pill Review

Silvets ReviewSilvets is a capsule-type dietary supplement manufactured in the USA for the Saudi Arabian company Key Player Ltd. It’s actually just their previous diet pill, Slimette, with a new name.

We have no idea why Key Player chose to make the change from the name “Slimette” to “Silvets”, but companies sometimes take this action when products have acquired a reputation for delivering poor results or not working at all. We are not saying that is the case here, just that it happens and could be a possibility.

Intended Method of Action

Key Player say Silvets boosts energy levels, increases the metabolism and decreases fat retention.

We are unsure exactly what they mean when they say the product decreases fat retention, but the other two benefits that are offered are common to most diet pills. A faster metabolism burns extra calories and this can lead to a calorie shortage that necessitates the burning of body fat for energy.

When people are short of calories they may also feel tired and lethargic, so diet pills often contain stimulants and/or other ingredients that elevate energy levels and help prevent diet-related fatigue.

Silvets Before and after

Active Ingredients

No inclusion rates are provided, but the capsules contain the following six ingredients:

  • Acai Berry: A nutrient-rich fruit extract that boosts the metabolism and helps suppress feelings of hunger.
  • L-Carnitine Tartrate: The results of a study conducted at the Univeristy of Rome suggest L-Carnitine may have the ability to delay the onset of fatigue.
  • Cayenne Powder: Research conducted at Laval University in Canada shows cayenne contains compounds that can increase diet induced thermogenesis and lipid oxidation.
  • Guarana: A natural ingredient that is often added to energy drinks because it delivers a slow release of caffeine and can be good for boosting energy levels for extended periods of time. Guarana is also a diet pill regular because caffeine is a proven metabolism booster and fat burner.
  • Green Tea: The antioxidants provided by green tea benefit the health in numerous ways and also have the power to trigger thermogenic fat burning.
  • Bioperine: A proprietary blend of piperine. The piperine alkaloid is obtained from black pepper and is added to supplements of all kinds because it improves the absorption rate of other ingredients.

How to Use – The capsules are intended to be taken two times per day with meals and the dose is one to two capsules. There are 60 capsules per bottle, so each bottle will last for 15 to 30 days, depending on how many capsules are taken each day. Diet and exercise is required.

Buying Options

Key Players have created a different site for each of the countries they are targeting. Customers based in the UK can visit and pay £32.97 per bottle (contains 60 capsules). People in Germany can go to and pay €44.18 per bottle.

The other site options are:

  • USA
  • Poland
  • Italy
  • Czech Republic
  • Spain
  • Russian
  • French

Similar sites are available for Slimette and anyone who wishes to try and buy it will find they are offered Silvets instead.

After Sales Service & Guarantee

The only way to contact customer services is to send an email to If you buy the product and want your money back there is no way to do so because Key Player fails to provide a money back guarantee.

Customer Comments

Key Player present the same customer testimonials on all the versions of the site and the names and locations of the people are changed to correspond with the country they are targeting.

The woman who supposedly lost 60kg by using Silvets is identified as Tina Miller on the UK version of the site and Key Player says she comes from Walsall. On the German site they state she is Emma Müller from Köln. The other sites award her alternative identities and locations.

SIlvets testimonialsHowever, the truth of the matter is her real name is Emma Duncan, she comes from Australia, and she didn’t lose 60kg at all. She lost 62kg, but she didn’t do it by using Silvets.

She took part in a TV series and was crowned Australia’s Biggest Loser in 20ll. You can read her story on ABC News and take a look at the same pictures that are used on the Silvets website.

Needless to say, in light of this revelation, we don’t believe any of the testimonials presented by Key Player and would have been interested to read reviews placed at a more trustworthy source. Unfortunately, none were available.

Potential For Side Effects

Side effect-free weight loss is promised, but Key Player say the formulation is not suitable for pregnant or nursing mothers.

The Final Judgment

Although Silvets contains some good ingredients, there are no customer reviews (from reliable sources) to show it can deliver the goods.

That makes it a chancy option. Especially bearing in mind the price and the fact that there is no money back guarantee. We are also not impressed by the fact that Key Player appear to have cut and pasted pictures of a minor celebrity from an Australian TV weight loss show and used them to promote their product in such an unscrupulous way.

It does not suggest a credible company and we cannot recommend Silvets. There are many better options available.

Atrafen Diet Pill Review – With Positive and Negative Customer Comments

Atrafen diet pillsAtrafen is a diet pill sold under the Nutratech brand name. The company also market a diet drop version of the product, named Atrafen Thermodrops, and a night-time option called Atrafen PM. Their other product is a carb and fat blocking combo called Orlistol. The company markets all four products via their official website and also operate an Amazon store.

As is often the case with diet pills, the manufacturer is making a lot of big claims, but not providing a scrap of evidence to back any of them up. Apparently men can expect an average weight loss of 14 or more pounds in the first month and women have reported an average of 11-13 pounds per month.

Atrafen Advertised Benefits

  • Satiety and appetite suppression
  • Increased calorie burning
  • Significant fat burning
  • Extra mental and physical energy

How The Pills are Supposed to Work

When the appetite is suppressed it becomes easier to be satisfied with less food because the hunger cravings are taken away. Less food means fewer calories. If the body is burning calories faster and getting less in a day it may run out. If this happens it will start to burn its stores of fat. When people do not get all the calories they need it can also make them feel tired. Atrafen us designed to prevent this from happening.

The Ingredients & What They Offer

Each capsule contains 600mg of active ingredients. The inclusion rates are not revealed, but the ingredients involved are:

  • Green tea extract: A health-enhancing ingredient that is added to supplements of all kinds. It’s proven fat burning abilities have allowed green tea to become particularly favored by the diet pill industry.
  • Caffeine anhydrous: An energy-providing stimulant that is good for improving mental focus. Caffeine is also a proven fat burner.
  • Raspberry ketone: A popular weight loss ingredient that was never fully exploited until the American weight loss expert, Dr. Oz, endorsed its weight loss boosting abilities, during one of his shows.
  • African mango (Irvingia gabonensis): Research shows African mango can “significantly reduce body weight and improves metabolic parameters in overweight humans”.
  • Acai: A berry extract that boasts a high nutritional value, acai is a respected appetite suppressant and fat burner.
  • Resveratrol: Study results published in the American Journal of Clinical Nutrition suggest resveratrol can help with weight loss, but other ingredients have more to offer.
  • Grapefruit powder: It’s possible grapefruit juice may provide some level of appetite supression, but grapefruit powder is unlikely to have a similar ability.
  • Apple cider vinegar: Some celebrities swear apple cider vinegar helps them to keep slim, but it is not a scientifically proven weight loss aid.
  • Kelp: A species of seaweed that is rich in iodine. Its presence here is only likely to benefit people who are iodine deficient. When the diet does not provide enough iodine the thyroid gland may not produce enough of the T-hormones that are necessary to govern the metabolism.
Best Way to Use  – The manufacturer has not made the usage instructions available online.

Atrafen Customer Comments

Customer reviews are mixed.

“Truly fantastic! I can’t believe how well these diet pills work. I am eating less food, but never feel hungry and have already started to lose weight. No side effects at all.” 

“The claims made for these pills are total garbage. They don’t do a bloody thing.”

“I used Atrafen with Orlistol and dropped 4 pounds per week. Never felt hungry at all.”

“Did not work for me. It’s a total rip-off. All the false reviews have got the manufacturer a nice little earner, but for dieters these pills are not worthwhile.” 

Atrafen Side Effects & Health Issues

The possibility of side effects is not mentioned. Nor is there any information about any special health considerations that may apply.

None of the ingredients have a reputation for causing problems, but the formulation is unlikely to be suitable for women who are pregnant or nursing a child. People who have health problems, or are using medication, should always check with a doctor prior to taking supplements of any kind.

Best Place to Buy Atrafen

Although it is possible to buy Atrafen directly from the manufacturer’s website, the best place to buy is Amazon. The price per bottle is a couple of dollars cheaper ($39.99) and free shipping is included as standard.

Customers buying via Amazon will also be protected by the Amazon Returns Policy, so getting a refund should not be a problem if the pills do not work as they should.

The homepage on the manufacturer’s website states they offer a money back guarantee, but any potential customer who takes the time to examine the returns policy will discover the company refuses to accept returns of any product that has been opened and tried.

The Final Judgment

Atrafen costs $40 or more per bottle, but no usage guidance is made available, so new customers have no way of knowing how long a bottle will last.

There are 60 capsules per bottle so, at a rate of two capsules per day, the bottle may last a month. If the dosage is higher it will empty a lot sooner. That would make Atrafen and expensive option.

Many of the ingredients are good, but the inclusion rates are unknown so the pills could be lacking in power. Customer feedback suggests the product may work for some, but not for all, and the manufacturer appears to be loathe to honor their offer of a money back guarantee. We cannot approve this product, but nor can we say for certain that it will not work.
