Megathin Review - Does This Diet Supplement Really Work? Are unproven ingredients and lack of clinical research deal breakers?

Editor's Review: 2.9 / 5.0

megathinThere has been plenty of talk surrounding Megathin weight loss pills, so we took it upon ourselves to write a comprehensive review, examining the side effects, ingredients, customer care and scientific studies. We additionally scrutinized hundreds of dieter reviews and user responses from all over the web. Finally, we condensed everything we found to provide you with the facts you need.

EDITOR'S TIP: Substitute Megathin with a proven fat burner such as Leptigen for better results.

What You Need To Know

Megathin is boasted as a natural weight loss supplement for both women and men. This formula is claimed to boost metabolism, suppress appetite and elevate energy levels. According to the website, this diet pill is very safe and effective, and rivals other over-the-counter weight loss products. It should be taken in the morning and evening with water (three capsules is a serving). The ingredients used in Megathin are; Sarsaparilla Root, Peppermint Leaf, Siberian Ginseng, Vanadium, Manganese, Ginger Root, Chromium, Damiana Leaf, Gotu Kola, Selenium, Nettle Leaf, Inositol, Choline Bitartrate, Bitaine, L-Carnitine and Guarana Seed.

From what we could gather, Megathin has been available since 2013 and costs around $50 per bottle, but there are bulk order discounts available. This supplement is sold with a 90-day money-back guarantee, but read on…

Unproven Ingredients for Weight Loss!

“The ingredients used in Megathin include Ginger Root, Damiana Leaf, Ginseng and Guarana, which are not proven to help with weight reduction and fat loss. In other words, this supplement relies on ingredients that have not been proven to cause weight loss,” says our Research Editor.

One customer stated, “Took Megathin for 30 days, but no weight loss yet.”

According to another dieter, “I don’t notice any appetite loss or energy boost at all.”

Lack of Clinical Studies

We did not find any science that supports Megathin weight loss capsules. This lack of clinical studies is concerning. One dieter commented, “Does this stuff really work. It says it’s one of the most powerful formulas out there. I’m not seeing it.”

“No weight loss for me. I won’t buy Megathin pills again,” said another user.

According to our research, if there is a specific part of a weight loss formula or diet program that is very concerning (unproven key ingredients, lack of clinical research, high price) the chances of prolonged fat-loss results are not good. Therefore if Megathin uses unproven weight
loss ingredients that fail to produce any real results in numerous dieters, this could be a serious problem.

The Science

At DietSpotlight, we need to see documented clinical studies that support the diet pill or weight loss supplement and the ingredients it uses. Sadly, there is no published science or studies that prove Megathin capsules actually aid with weight reduction or fat loss. With this diet pill, we unfortunately see a big red flag.

The Bottom Line

It’s obvious that Megathin makes some serious weight loss promises. However, there really doesn’t seem to be any evidence that supports Megathin capsules for solid weight reduction. While it’s good to see that natural ingredients are used, the negative customer reviews are enough to deter many dieters.

For those who want to see more significant fat loss, we encourage you to try a weight loss supplement that is supported by both positive user reviews and clinical trial results.

Among the most promising weight loss products we’ve spotted in 2015 is leptigen. This diet supplement contains a blend of four key ingredients, which have been proven in published clinical trial research to help increase fat loss and kick-start metabolism. Furthermore, we can’t locate any customer complaints regarding negative adverse effects and user reviews posted on the web show people are seeing excellent results.

Also, the makers of Leptigen are so confident in their product they’re offering a special trial offer, which is a good sign.

Megathin is an all natural diet supplement that claims to curb appetite, boost energy, increase metabolism, and help you drop pounds easily. Megathin also claims to be one of the "safest and most powerful dietary supplements on the market". Megathin uses only all natural botanical ingredients so it may appeal to dieters who don't want any strange chemicals in their supplements.

The official Megathin website insists that, by using this product, your body will actually activate it's own built-in fat burning system. It doesn't go into detail in this area but a quick glance at the ingredients will show you that a few stimulants and thermogenics are present. The official website also says multiple times that even though Megathin contains these stimulants, you will feel energized instead of jittery or nervous, which is a promising claim.

List of Ingredients

Megathin contains: Manganese, Chromium, Selenium, Betaine, Choline Bitartrate, Inositol, L-Methionine, Siberian Ginseng, Guarana Seed, L-Carnitine, Ginger Root, Damiana Leaf, Gotu Kola, Nettle Leaf, Sarsaparilla Root, Peppermint Leaf, and Vanadium. Other Ingredients: Rice flour, partially hydrogenated cottonseed oil kosher, NF, Gelatin Capsule.

Product Features

Megathin is basically a combination of thermogenic and stimulant ingredients. This means you will have a slight boost in your body's core temperature combined with extra energy. Many people will exercise more or just do more around the house which in turn leads to burning more calories than usual. The official Megathin website will tell you that you may drop a few pounds without changing your normal routine, but that those with better eating habits will probably lose more weight.

Megathin does offer a 90-day money back guarantee which is nice. 30 days may not be enough time to fully gauge a product's effectiveness but 90 days is just right for the diet supplement world. The official website recommends buying a 90-day supply at once which can be very expensive. You will save $100 buying 6 bottles at once but that is still almost $200 you will be spending.

  • Contains all natural ingredients.
  • Comes with a 90-day money back guarantee.


  • Expensive. Over $50 with shipping costs for a 30 day supply.
  • Contains no well known appetite suppressants or fat burners.
  • The official website offers no clinical trial data.


Many people will see that Megathin has all natural ingredients and that might be enough for them to consider buying it. There is definitely a lot of attention going into marketing products that are fairly natural, the reasoning behind this being that these may not produce many side effects. We can't get fully behind Megathin at this time, however, because there are dozens if not hundreds of similar products that you can find around the Internet for much cheaper and that contain a proven appetite suppressant or fat burner.
