Proactol Plus Ingredients

Proactol Plus uses a natural fibre found in a cactus plant called Opuntia ficus-indica (also known as prickly pear).

One fibre is non-soluble that binds with fats in your stomach from your meal making them harder to digest. The other fibre is soluble which works to slow down digestion helping you to feel fuller and so less hungry!

Unlike many diet pills ingredients, especially the synthetic ones found in many stimulant based fat burners, the ingredients are suitable for vegetarians.

Here is the full list of ingredients based on a serving size of 3 tablets:

  • Opuntia ficus-indica (1.605g)
  • Dietary fibre (1g)
  • Calcium (195mg)
  • Carbohydrate (2g)

Watchdog Verdict

Proactol Plus is considered one of the better fat binders on the market and from consumer feedback looks to have less side effects than other similar products.

We liked the fact there are real clinical trials suggesting you can reduce dietary fat intake without massive changes to your diet.

So far so good, however, it’s worth noting that calories blocked by this supplement will be fairly low and so weight loss will likely be very slow (you can read our article on fat binders: do the calories stack up here).

The manufacturers offer a 60-day money-back guarantee. So if you’re not entirely satisfied you can simply contact them and request a refund! But remember the guarantee is not available on EVERY purchase but on purchases of 4 months or more and as long as you adhere to the guidelines.

Whilst it is/was a better product than many out there, we cannot approve Proactol Plus as it no longer exists.

  1. I tried Formoline L112 and and to me it is a very good fat binder. because I lost 2.5 lb the first 10 days.I am not sure if Proactol Plus is better or worst, I am just reporting my result with an Alternative product.

  2. I’m trying to lose weight but I’m struggling as I eat very well but I never have time to exercise as I am always in work. Would these pills still work on me? Will I lose a good amount of weight?

    1. Hi Sofia,
      Our article on “fat binders: do the calories stack up?” best outlines how fat binders can be a slow way to lose weight. Actual weight loss will depend on the amount of fat in your diet. So in simple terms, eating a diet comprising 40% fat means you could block up to 240 Kcalories per day, which equates to 1/2lb per week (2lb per month).

  3. I don’t eat a lot of fatty/greasy meals (maybe none) but I do eat a lot of sugar from candy/gummies/etc (don’t like chocolate) and from fruit. Do you think Proactol would still be effective for me or should I chose another supplement?

  4. hi i have the diet plate and bowl and i use my rower for 30 to 35 mins a day having 1 to 2 days split rest a week also i take prosolution pills my doctor tolled me they would help my over active bladder i would like to know if i can take proactol plus and would it help me lose weight i`am 39 and 18 stone 13 pound i put the weight when i became my mums full time carer please help

  5. Interesting that the women in the study did two things. 1. Took the pills. 2. Kept a food diary.

    There is lots of research showing that women keeping a food diary tend to eat less.

    How can we know that taking the pills did more than just keeping a food diary would?

    1. Hi Seema,
      The official site appears to offer the option to ship to “South Africa” and there shouldn’t be anything in there that customs will be concerned with. To double check, we would suggest contacting the manufacturer for the latest information.

    1. Hi Kely,
      We were very surprised to hear your results. Did you change anything such as your diet or exercise? Taking a weight loss supplement certainly shouldn’t cause you to gain weight and we haven’t heard of this before. Any further information would be most useful.
      Kind regards,
      Diet Pills Watchdog Team.

  6. Can someone help me please.

    i have an underactive Thyriod and take medication for this.
    can i still take these tablets to help me losse a few stone??

    1. Hi Kerry,
      Thanks for your comment. As with any diet pills, if you’re taking prescription medication you are advised to speak to your health professional/GP to ensure its safe for you to take both at the same time. They will be fully aware of your medical history and will be best to advise you.

  7. I have ordered 3 months supply plus an extra 2months.
    I tried alli a few years ago with great results but a lot of side effects.
    I have already lost 2 stone with diet and exercise but have hit a wall on losing my last stone and a half.
    Hopefully this will help me.

  8. I first found out about proactol when looking online for xls fat binder. I decided in the end to go for proactol as its a lot cheaper, only taken for 2 days and yet to weight myself but feel like I eat less. These are not overnight magic pills so will check the scales the end of the week 🙂

    1. I was looking at this website and more inclined to go with the Proactol but waiting to see how you get on…… Fingers crossed for you.
