Diucaps is a diet product I will surely never forget. We did one of our in-depth reviews, taking a good look at the ingredients, side effects, level of customer care and scientific research. Moreover, we looked at all sorts of user comments we discovered online. At this point we summarized and condensed all the info to give you the bottom line.

What You Need To Know About Diucaps

First off, Diucaps is a weight management formula made by Legere Pharmaceuticals, which is located in Scottsdale, AZ. The ingredients are L-phenylalanine, pantothenic acid/vitamin B5, pyridoxine HCL/vitamin B6 and vitamin C. [1] [2] This product is one of several weight-loss supplements offered by this brand. Specifically, it aims to enhance mental focus, control binge eating, reduce food cravings and regulate mood. You are directed to take 3-4 capsules daily.

This supplement was released back in 2012 and can be acquired through online stores such as Amazon for $36.99 (90 capsules). No special diet or exercise plan is needed. Diucaps does provide some vitamins and amino acids, but read on…

Diucaps Poor Results – “A Consideration?”

The first issue dieters may want to consider is that Diucaps ingredients may not provide the results they’re looking for. According to our Research Editor, “Diucaps has not been proven for weight-loss. While the vitamins and amino acids used do benefit the body, they are unlikely to really suppress appetite and encourage weight reduction.” [3] [4]

One customer revealed, “I’m so dang mad. I have been taking these as directed, I have been eating less (and healthy) AND going to the gym 3 days a week and have not lost one dang pound, if fact I’ve freaking gained weight.” [5]

“I really did not like it, did not stop or help my hunger,” said another user.

Customer Complaints – “Too Many!”

We did not find any customer testimonials or success stories posted on the official website for Diucaps. However, we did find user complaints posted on other websites. One buyer stated, “I paid over $70 and huge waste of money. I need a refund!!!”

Another user commented, “This stuff does not work at all.”

Our research has proven if one particular aspect of a weight-loss pill or diet program is very troublesome (unproven ingredients, user complaints, a difficult or painful exercise) the odds of long-term results are not good. Therefore if Diucaps do cause numerous negative reviews, this could be a deal breaker.

The Science – “Clinical Backing?”

We took a close look at the official website, but could not find any clinical studies or research to support the weight-loss claims regarding Diucaps. We at DietSpotlight need to see some documented science in order to stand behind the product and in this case that’s just not available. 

The Bottom Line – Does Diucaps Work?

Well now, are we in a frenzy about this one? We are glad to see that this supplement contains vitamins and amino acids, but we do not believe Diucaps is a good choice for weight management, because there are some negatives to consider. Put simply, there are no ingredients used in this product that are proven to help with appetite suppression and reduced food cravings. Furthermore, we did not find any positive customer feedback posted on the official website.

If you’d like to see more significant fat loss, we recommend you go with a diet formula that is supported by actual scientific studies and has received plenty of positive customer reviews.

Among the best products we’ve seen this year is one called Leptigen. This diet supplement contains four proven ingredients, which have been shown in documented scientific research to help accelerate metabolism and increase fat loss. We can’t pinpoint any discussion of negative side effects and dieter reviews posted on the internet indicate people are seeing significant results.

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

Diucaps: What You Should Know

Diucaps is a dietary supplement fortified with the amino acid complex L-Phenylanine as part of their appetite suppression formula, which they claim helps decrease hunger signals in the brain. Their only purpose is to provide appetite suppression, but this supplement is not fortified with potent Hoodia Gordonii. They mostly depend on L-Phenylalanine and select vitamins for a limited weight loss approach. An extremely affordable alternative to other appetite suppressing pills, Diucaps is an economic choice for dieters interested in a different formulation. Its website offers very little information about how Diucaps truly works to eliminate appetite, however. Diucaps has a very limited approach, but the combination of this product's low price (one 30ct bottle costs $11.99) and simple formula is sure to attract dieters in need of an extra boost. Although the formula behind this diet pill may not be the strongest available, dieters may experience some benefits. There are no money back guarantees offered on its website, but the wide availability and price makes up for it. Now let's evaluate how Diucaps truly works.


L-Phenylalanine, Vitamin C, Vitamin B6, Pantothenic Acid.

Diucaps Product Features

Diucaps claims that their key active ingredient, L-Phenylalanine, helps reduce hunger signals to the brain, therefore effectively suppressing appetite. This in turn contribute significantly to weight loss. Is this true? To an extent, yes. One study conducted on L-Phenylalanine showed that the amino acid helped increase production of cholecystokinin, the chemical that activates once a person is full. The chemical is released earlier (cholecystokinin usually actives 20 minutes into food consumption), which helps suppress appetite. It is important to note these studies were conducted on animals and not humans, which may skew the actual results. L-Phenylalanine appears to have verifiable results, but there is little offered beyond appetite suppression. A complete diet supplement should contain more angles of weight suppression, including stimulating the thermogenic processes (such as ingredients that increase energy and burn fat) to fully implement weight loss.

Advantages of Diucaps

  • One study showed L-Phenylalanine did help increase fullness signals, therefore reducing the amount eaten.
  • Diucaps are extremely affordable -- one bottle costs only $11.99.
  • There are no dangerous chemicals used in Diucaps.

Disadvantages of Diucaps

  • This product should be avoided by people diagnosed with Phenylketonuria.
  • It will only suppress appetite, not stimulate the metabolism.
  • It is not clear why Diucaps included akk ingredients.
  • There is little information about Diucaps on its website.


Although further testing is needed, Diucaps' claims are legitimate. L-Phenylalanine will help suppress appetite, but there is little else this amino acid will do for weight loss. This supplement is too limited to offer full weight loss support for all dieters, but for dieters who desire a supplement to suppress appetite, Diucaps might be just as effective as Hoodia Gordonii for half the price.
