What is PGX Daily?

First off, PGX Daily is supposed to help reduce appetite, promote healthy blood sugar levels and assist with weight management. The ingredients are PGX (PolyGlycopleX) 2.5g, konjac root, sodium alginate and xanthan gum. This supplement can be used with any weight-loss program. There are also PGX Daily softgels available. This product is available in packets, which are simply added to water. You add one packet to eight ounces of cold water or juice and then drink. You can take it twice a day. [1]

Bad Taste – “Can You Handle It?”

Our first consideration with PGX Daily ingredients is the number of reports of poor flavor. “Unfortunately many customers have complained about the taste, which is never a good sign,” said our Research Editor. “You need to ask yourself how is the product really going to benefit you if you have difficulty consuming it on a regular basis.” [2]

According to one customer, “These do not dissolve well at all, and if you mix in water it’s like you’re drinking water with gelatin chunks in it.”

“Didn’t like it at all. It was like gel consistency. Awful tasting and won’t buy again,” commented another user.

Based on PGX Daily reviews, poor taste wasn’t a concern.

I take it w/ water, it tastes like nothing and has a texture that reminds me of OJ pulp when drinking it down,” reported a customer.

PGX Daily Customer Testimonials

Side Effects – “Another Concern?”

PGX Daily side effects are something we found in plenty of customer reviews. One user stated, “Followed the directions and it gave me the absolute worst gas ever. That’s not an exaggeration either.” [3]

Another customer revealed, “If you tend to be on the constipated side and don’t like drinking water, this product is not for you. I drank the recommended amount of water with it and it didn’t help.”

After searching for PGX Daily side effects, we found that some users didn’t experience adverse reactions.

I found that it works without side effects. Nothing like the feeling you get after taking regular fiber supplements at all…we all know how that feels,” said a user.

A good appetite suppressant that doesn’t have a bunch of side effects. Has improved my digestive health,” commented another.

The research we’ve conducted has shown if there is one facet of a supplement that is concerning (a painful/difficult exercise routine, unpleasant taste, too many side effects) the real likelihood of weight-loss for the long term is slim. This means if PGX Daily does in fact have as bad a flavor as described, what’s keeping the dieter from switching it out for a clinically tested formula? [4]

Any Actual Science?

It is mentioned online that PGX Daily is clinically proven. [5] However, the details of this research are not entirely disclosed.  Therefore, we cannot state whether or not it is actually backed by real science. At DietSpotlight, we need to see proof before we get behind a diet product. This is especially important when there are clinically tested ingredients in supplements shown to help dieters lose weight. [6]

What Users Are Saying

“After I finished my first huge bottle, I discovered them on Subscribe & Save. How convenient to not have to remember when I’m running low to order more…”

“I am using these with a detox plan, and I am losing weight consistently. I will continue to take them and recommend them highly.”

“Gave me abdominal pain and gas. I experienced shortness of breath and bad sinuses. Not for me.”

The Bottom Line – Does PGX Daily Work?

So, should you run out and buy PGX Daily? Well, we like the longevity of the company and that we found some positive comments, but we’re a little concerned because it’s not backed by solid science. [7] Plus, numerous customers have complained about side effects and the less-than-savory taste. [8]

If you’d like to shed more pounds of fat, we recommend you go with a product that does not taste bad, contains clinically tested ingredients and is not associated with many side effects.

Among the best products we’ve seen this year is one called Burn HD. This product uses a proprietary blend of four ingredients that have been shown in clinical testing to help improve fat loss and kick-start metabolism. You should know that we can’t find much talk of harmful side effects and user feedback around the web shows people are seeing great results. This is exactly what we think dieters should be looking for in a weight-loss supplement.

The makers of Burn HD are so satisfied with their product they’re offering a 2-Week Sample, which is a good sign. Really, the only thing you have to lose is that extra weight!

We dug deep into the PGX Daily ingredients to give you the details you need.

PolyGlycopleX (PGX)

PGX is a patented fiber complex found in a number of supplements. It is made with natural ingredients.

What is it Supposed to Do?

PGX fiber is supposed to expand in the stomach over at least 30 minutes, though sometimes, it can be longer. As such, when taken with a glass of water, it can promote a feeling of fullness. It works by absorbing water, filling the stomach, and slowing down the digestive process. It’s supposed to keep the blood sugar from rising too much after meals, which is also thought to help keep cravings at bay.

Clinical Research

According to a study published in Nutrition Journal, “A realistic high protein weight-reducing diet was associated with greater fat loss and lower blood pressure when compared with a high carbohydrate, high fiber diet in high risk overweight and obese women.”

Konjac Root

Konjac root is a plant that grows in Asia. Inside the root, there is a sugar that is used as a fiber. [1]

What is it Supposed to Do?

It is a source of fiber, also known as glucomannan. It absorbs water and bulks into a gel to serve as an appetite suppressant and may help lower cholesterol as it passes through the system. In foods, it is sometimes used as a thickener or gelling agent. Glucommanan is also used to treat constipation, diabetes as it may help lower blood sugar levels, and high cholesterol.

Clinical Research

According to a study published in International Journal of Obesity, “Serum cholesterol and LDL were significantly reduced in the glucommanan treated group.” There’s also research that states fiber can help with weight-loss as an appetite suppressant.

Sodium Alginate

Sodium alginate is a polysaccharide extracted from brown seaweed.

What is it Supposed to Do?

When mixed with water, it thickens and binds. It makes food thicker and emulsifies ingredients.

Clinical Research

According to a study published in the journal Obesity, “Alginate treatment over 10 days has no effect on gastric motor functions, satiation, appetite or gut hormones.”

Xanthan Gum

Xanthan gum is a polysaccharide. [2]

What is it Supposed to Do?

It is used in food and baking to thicken and emulsify.

PGX Daily Scientific Abstracts


By the end of the study, insulin sensitivity, kidney, liver, and pancreatic histopathology were examined and thus determined. Body weight and food consumption had been significantly decreased by PolyGlycoPlex as opposed to inulin and cellulose. There had been a significant reduction in serum insulin in fated and non-fasted states and blood glucose caused by PolyGlycoPlex. Insulin resistence was greatly reduced by PolyGlycoPlex in the 5th week throughout the 8th. This went for the terminal OGTT scores in fasted as well as fed states. There was a reduction in serum total cholesterol as well, reduced by PolyGlycoPlex, which had also greatly reduced histological kidney as well as hepatic damages. This was all in addition to decreased cholestasis and hepatic steatosis. A bigger mass of pancreatic β-cells were discovered in the PolyGlycoPlex participants group. This had concluded that PolyGlycoPlex could be a useful additive in the diet for controlling the development of early stage metabolic syndrome. [1]

Results from the study had indicated that PolyGlycoPlex was very well tolerated as a part of a regular diet. It was shown to have only mild negative effects which were similar to the effects of a moderate dietary fiber diet. PolyGlycoPlex is highly viscous, which is why it demonstrates a plethora of physiological responses like maintaining healthy uric acid and total and LDL cholesterol levels. [2]


Glucomannan fiber or placebo was administered in 1g doses of two 500mg capsules along with 8 ounces of water, 1 hour before each meal for 3 meals per day. Participants were told not to change their normal eating habits or exercise routines. The results were significant; showing a mean weight-loss of 5.5lbs on the glucomannan throughout an 8 week period of time. Serum cholesterol as well as low-density lipoprotein cholesterol was greatly decreased in the glucomannan group (21.7 and 15.0 mg/dl respectively). [3]

Sodium Alginate

There were no differences in weight-loss between the participant groups in the intension-to-treat analysis (P > 0.1). There were, however, greater weight-loss in the completer analysis (n = 80), that were shown to occur with alginate (6.78 ± 3.67 kg) vs. placebo (5.04 ± 3.40 kg) (P = 0.03). Plasma concentrations of glucose, C-reactive protein, ghrelin, insulin, HOMA-IR, and lipid metabolism had shown no differences between the groups during the intension-to-treat analysis (P > 0.1). It was concluded that the results had indicated alginate as an adjunct to energy restriction could trigger weight-loss in obese patients who had finished a 12 week dietary intervention. [4]


Previous PGX Daily Review (Updated January 1, 1970):

What You Should Know

Think about what you need your dietary supplement to do for you or assist you with. This is always a good starting point before you dive into the vast and plentiful market of capsule and tablet formulas. One product that may be able to assist you with weight management and normalizing your blood sugar levels is PGX Daily. It is brought to you by Natural Factors, and comes in a liquid softgel form.

It is unfortunate that the “proprietary blend” of ingredients for PGX Daily are not revealed. However, it is clear that this product contains both soluble and dietary fiber (this assists with regularity and satiety/feeling of fullness). This supplement additionally offers Medium Chain Triglycerides, which may aid with regulating the user’s blood glucose levels.

List of Ingredients

PGX (Polyglycoplex) Proprietary Blend, Medium Chain Triglycerides, Gelatin, Glycerin, Purified Water, Annatto, Carob, Yellow Beeswax, and Soy Lecithin.

Product Features

PGX Daily is a dietary supplement suitable for both women and men alike. It is claimed to support healthy weight reduction, as well as overall good health. More specifically, this softgel formula assists by lowering the glycemic index of the meals you consume. In turn, this promotes healthy blood glucose levels. Overall, PGX Daily is claimed to encourage a feeling of satiety or fullness, and help regulate the user’s metabolism. It does not boost thermo genesis or increase energy levels. PGX Daily is directed to be taken with each of the three main meals of the day (although you should begin with 1-2 softgels per meal, over time you can build up to 3-6 softgels). Each time this supplement is taken, it is important to drink at least eight ounces of water. PGX Daily can be acquired through online dealers like The Vitamin Shoppe for $29.86 (the retail cost is stated to be $39.95).


  • This dietary formula may regulate appetite and minimize cravings.
  • There is one positive review posted on thevitaminshoppe.com for PGX Daily.
  • This supplement is free of Ephedrine.


  • A full ingredient list for PGX Daily is not revealed.
  • Some dieters may have allergic reactions to certain ingredients in this formula.
  • There are no free trial samples of this product offered.
  • No clinical research is provided to support the claims made about PGX Daily.


When it comes down to it, PGX Daily is really more of a fiber supplement than anything else. This explains why it promotes satiety and helps regulate blood sugar levels. Although this formula may be fine to take daily, it will unlikely assist users with burning fat or increasing their metabolisms. On the bright side, PGX Daily may be able to aid diabetics or assist some individuals with regularity.

  • Rhonda

    Was wondering if you need to exercise more or just do same daily routines?

    • Cameron (Editor)

      Any exercise improves your chances of weight loss. If you reach a plateau however, switching up your daily routine will do the trick.

    Need to know if there is any reaction to other medications called Jardiance or thyroid and naproxin and setrline, renedil, micardis, humalog 50 mix?

    Is it possible that PGX could make my folate level high? Also I am taking it with a vitex combo menopause supplement and want to know if that is safe. Thank you

  • persons with a heart condition

    Is PGX OK for use by persons with a heart condition?

    • Karen

      My doctor’s nurse told me it is not safe to use things that increase metabolism if you have heart issues. I have a history of heart issues in my family and the nurse said I was taking three suppliments that had ingredients that changed metabolism! I was not aware as most are just marketed as appetite depressants, blood sugar regulator, etc. Be careful, combinations can be lethal in certain people.

    • Maribel (Editor)

      Hi albert! Because of possible interactions with having a hear condition, please make sure to consult with your physician before taking this product.

  • christine pierangeli

    I have trouble managing my blood sugar. I’m a nutrition therapist with a very healthy diet and I have found PGX has really helped me control cravings and any desire to overeat. I have been pleased with how the fiber has helped with elimination (no constipation at all). As a nutrition therapist I am VERY aware that every body responds differently. My recommendation would be to start very slowly, only 5-6 grams per day for a week to see how YOUR body is going to respond. If you have a low fiber diet currently then gas and bloating will almost certainly be an issue. Work up to slightly higher doses as your body is able to adjust. I take it in capsule form. I take 16-24 ounces of water with EACH capsule. This is absolutely necessary so that you keep the fiber moving in the right direction. Less than 16 oz with each capsule could be very hard on your digestion.

  • Rita

    I take one PGX softgel per day and that keeps me feeling full, eliminates my cravings and is not at all constipating; just the opposite. I am very satisfied so far.

  • Stephanie

    Just started n I’m having running belly,is this good r bad.

    • Anna (Editor)

      Hi. Please make sure to consult with your physician before continuing to take this product and let them know about the side effects you were experiencing. You might want to consider switching to a supplement with clinically researched ingredients, like Dietspotlight Burn.

  • Vi

    Hey, I take pgx, great appetite suppressant. But, I only take about two or three of the capsules a day. Any more cause gastric distress, just don’t take the recommended amount – take about half and then drink a ton of water and you’re good to go.

  • Emeralde

    People are really misguided if they think they can eat in the same old way that made them overweight in the first place and lose weight. Get rid of the carbs – they don’t need them. They aren’t essential. FAT IS ESSENTIAL AND PROTEIN IS ESSENTIAL. It doesn’t matter what they take, if they eat junk food, pop, and prepackaged food along with bread and grains they aren’t going to lose weight. It has nothing to do with PGX. The ingredients in PGX are natural and should work well with the metabolic system if they eat properly, so little meat and only chicken breast and oily fish like salmon 3 or 4 days a week, beans, tons of cruciferous greens like spinach and Kale and beets, Kefir milk for a healthy gut, berries and stay away from the sugar. SUGAR MAKES YOU FAT! NOT FAT. NO WHITE SUGAR. Eat healthy fats like olive oil, almonds, coconut oil, avocados, I guarantee you you will lose 1-2 lbs in a week. PGX is an appetite suppressant and if it is taken as directed, it will kill your appetite until you lose your cravings – drink green tea for cravings. Then you can stop taking it once your appetite has diminished. I eat like this without any appetite suppressants and have lost 22 lbs in l0 weeks.

    • Doug

      Well said Emeralde. I would suggest “white” Tea as it has many times more antioxidants. Add lemon water (filtered RO water) warm each morning with organic ginger and apple cider vinegar. Try Walnuts, Macadamea, Avacados and 35% cream which has 0 carbs/sugar ☺️

    • Mikq

      Esmeralda, Vegetables ARE carbs. You are saying that carbs are not essential yet you are saying we should be eating them. Anything that is not a fat or protein is a carb. Brocolli is a carb

  • C Haines

    I have been using this product for a few weeks and have not side effects, I don’t get gas as others have indicated and drink the water suggested. I stir it in juice and just make sure I stir quickly and drink immediately. I also combine with healthy eating and exercise. I have had trouble with weight loss for 3 years my weight didn’t budge! I was so frustrated. I exercise an hour a day 5 days a week and still was not losing weight. There is no taste to this product and yes I do get a few small clumps if I don’t mix good. Other than that for me it works great!

  •  I have ended up with lots of gas!
    Lm (Verified User)

    I was excited to try this and followed it very strictly. I have ended up with lots of gas and my output is so hard that it gives me some light bleeding. Bye, bye PGX. So sad.

    • Jae

      You are supposed to drink with 2 cups of liquid. I use sugar free drinks to wash my gel caps down. Keeps me regular. Hope this helps.

  •  It's Awesome !!
    Della (Verified User)

    Awesome!!!! I’ve using this product for almost a weak and I already dropped 10 pounds, I take 6 soft capsules a day, and I never feel hungry…follow this product as directed and you won’t be disappointed

    • Vincent

      10 pounds in one week is WAY too much to be sustainable. It’s too much, too quickly. And I hope for you it’s not mainly water…

  •  Would not recommend Pgx

    Ruth (Verified User)

    I tried this product for several days and I developed a migraine that lasted for 3 days (I stopped taking PGX and the migraine went away) and I was unable to sleep. While I do suffer from migraines normally I have never had one that lasted that long that would not respond to my normal headache tablets and I have never had sleep issues. I would appreciate knowing the side effects. I noticed in these comments someone else was getting headaches. I will continue my research on this product

  •  60% willpower - 40% PGX
    Ryan (Verified User)

    Having never had struggle with overweight most of my life until a very serious accident almost claimed my life. I took comfort in food and gained almost 70 pounds in a matter of 2 years. I have been overweight for 7 years now and tried various diets with no success. I finally said “ENOUGH”. In November I began using PGX, seriously. In the last 12 weeks I have lost 35 pounds and continue to drop. You must harness your own will power most importantly, but by using PGX right before I eat, I consume half the amount. After about 30 days I noticed my unquenchable desire for sweets dissipate. It’s still there but not as all consuming. I need to use about 18 pills a day, any less for me is not effective.
    60% willpower – 40% PGX

  •  I loose my weight
    Judy Chartier (Verified User)

    I have been using it for about six months and i have lost 14 pounds mostly in the middle core area which is what i wanted to do.I have had so many surgeries that i had a hard time getting it off because i lost so tone and gained a lot of fat in the area, due to not being able to exercise off and on for several years. I am 73 years old and am now able to exercise in comfort. my top weight was only 120 pounds but at 5 feet that was a lot for me, and i felt very sluggish ,now i feel so much better, i want to know if there are any side effects. I drink lots of fluid mainly water. so if you can get back to me and let me know what to look for if any i would appreciate it. i have told several people about it and they all are going to try it. It is so easy and i am not a big eater anyway so thank you for having this available for use. Judy

  • debbie neville

    I’ve used pgx in the past and just started using it again to help lose the 5 to 10 extra pounds I’ve gained over the summer. I love pgx I take 6 pills either before with or after I’ve eaten and it keeps me full much longer so I’m not eating as often or as much, I also don’t crave the sweets even when I look at them. because my stomach feels full, I have no desire to eat them and I’m a person who eats mostly sweets. It’s a great product, it helps with my constipation but may give other people gas or loose stools if they are normally regular. but you need to take the max amount to work well.
    I love it, love it, love it for weight loss. I feel full and don’t eat as much. and I eat some junk still and don’t exercise and still lose weight, about a pound a week.
