Eternal Lean Review - Does This Diet Supplement Really Work? Are fad diet ingredients and lack of results deal breakers?

Editor's Review: 3.5 / 5.0

84831645We’ve seen plenty of discussion online about Eternal Lean capsules, so we conducted an in-depth review, focusing on the ingredients, side effects, customer service and clinical studies. We also examined hundreds of user comments from all over the web. At this point we condensed everything we found to give you the important facts you need.

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

What You Need To Know

First off, Eternal Lean claims to assist the body in several ways, which include the following; increase metabolism, improve lean body mass, encourage fat loss, balance blood sugar, block the absorption of sugars and starches, lower stress levels, elevate energy, suppress appetite, modulate fat production and block fat activity. The ingredients are raspberry ketones, coleus forskohlii, SynaptaLean, InnuGuard, brown seaweed extract, LipoShield, Super CitriMax, green tea, rhodiola rosea and ginger. You are supposed to take three each day. It is portable, so you can take it anywhere.

From what we could gather, Eternal Lean was released in 2013. This supplement is available online for $26.71. Natural ingredients are used and you can purchase this directly from the website, but read on…

Fad Diet Ingredients – “No Go?”

The first issue with Eternal Lean ingredients is the fact that there are no clinical trials that back weight-loss claims. “This diet supplement contains raspberry ketones,” says our Research Editor. “The trouble is science actually proves this one does not work.”

According to one user, “I tried this and didn’t really like the way it felt, more like hurting my stomach.”

Another customer stated, “Didn’t make me lose any pounds.”

Lack of Results – “Another Concern”

We did not find any clinical trial results posted online to support this supplement. In fact, one user commented, “Does not work like it says.”

“Been using this product for four weeks and no fat loss,” said another dieter.

Our research has revealed that if there is one aspect of a weight-loss pill or program that is especially bothersome (a painful/difficult exercise routine, lack of clinical results, fad ingredients) the real probability of long-term fat loss is low. In other words, if Eternal Lean is not effective for numerous users, this could be a major issue.

The Science – “Any Proof?”

While the official website for Eternal Lean does present some information on the ingredients used in this diet pill, there is no real science provided to back the fat loss claims. At DietSpotlight, we must see documented scientific studies that support the weight-loss product or else we only see a red flag.

The Bottom Line – Does Eternal Lean Work?

Alright, what’s the final take on this one? We appreciate that Nature’s Plus, the company that makes Eternal Lean, has been around since the 1970s. Clearly this brand has stood the test of time. However, due to the fad diet ingredients and lack of clinical results, we have reservations about recommending Eternal Lean for fat loss and long-term weight management. Also, we did not find a 100% satisfaction guarantee posted on the official website.

If you wish to see more fat loss results and a slimmer figure, we recommend you select a product or weight-loss formula that is supported by clinical studies, does not contain fad diet ingredients and is affordable as well.

Among the best products we’ve seen in 2015 is one called Leptigen. This supplement uses a proprietary blend of four ingredients, which have been proven in documented clinical research to help increase fat loss and elevate metabolism. We have not found any complaints of harmful effects and dieter reviews on the web express people are seeing substantial results.

To boot, the makers of Leptigen are quite confident in their supplement so they’re offering a Special Trial Offer, which is an amazing sign.

Eternal Lean from Nature’s Plus can be purchased online directly from the supplement company or through a third-party online vitamin shop. The official website does a fantastic job of listing main ingredient and providing a scanned image of the product label. Eternal Lean is not a simple weight loss supplement. This supplement contains more than 20 ingredients, many of which we come across every day, but rarely in the same supplement.

Product Features

Chromium may help the body naturally regulate blood glucose (sugar) response. The effect is often reduced cravings for sweet or sugary snacks between meals when taking with a meal. Raspberry Ketone is the star of the weight loss world right now. There is little, if any, clinical proof raspberry ketone has a significant impact on weight loss and most studies are on mice – not humans. Inulin is a source of fiber. Fiber slows digestion and may help reduce hunger. Fiber helps promote a healthy colon, regular bowel movements and digestion. The SynaptaLean complex supports brain function, according to Nature’s Plus. The only ingredient of importance in the complex is the phenylalanine. Phenylalanine alters mood and may interfere with some prescription medications. Of the remaining ingredients, green tea extract promotes metabolism and overall health. There is 200 mg per three capsules and the dieter takes one serving per day. The 200 mg is slightly lower than we’d suggest for optimal benefits, but at least the company lists the amount of green tea in the formula. Garcinia Cambogia is on the hot seat right now due to claims of liver damage associated with products containing the ingredient. We thought the ingredient list was interesting enough, but there is a warning on the product label that takes the cake. We are constantly warning dieters that phenylalanine is not safe for anyone with mental health issues, especially if prescription medications are being used to control symptoms. The label for Eternal Lean warns schizophrenics to consult a doctor prior to taking the supplement. The phenylalanine is a dopamine agonist, according to Nature’s Plus.

  • Ingredients listed online.
  • Eternal Lean is sold on the official Nature’s Plus website.
  • Contains green tea and chromium.


  • Some of the ingredients are unsafe for certain dieters.
  • Garcinia cambogia may be associated with negative side effects.


Eternal Lean is not the best weight loss supplement on the market and, based on the label it is not safe for people with schizophrenia. There are likely other mental disorders that could be affected by the addition of phenylalanine.
