Slim+Trim is a new weight loss bundle that brings together two established products at a lower cost.

We’ll be honest with you – we’re big fans of the two products, Phentaslim and Phentatrim, when judged on their own merits. This bundle isn’t just cost-effective; it represents a double-fronted approach to weight loss.

So, what happens when you pair the best fat burner with the best appetite suppressant? You lose weight – it’s as simple as that. Slim+Trim includes everything you need to shred fat and to look and feel absolutely amazing. We highly recommend it.


  • Trusted, established products proven to work
  • Natural ingredients in optimum dosages
  • Free Shipping and a 60-day money-back guarantee
  • Additional 150-page weight-loss guide


  • Phentaslim may need smaller serving if you’re sensitive to caffeine
We’ve always been big fans of Phentaslim and Phentatrim, and now this pair of fat destroyers are available in an easy-to-buy bundle, so you don’t have to choose between them.

Phentaslim has been around for a long time now, and for good reason: it works! There are just no other supplements out there that can hit the same levels of fat-burning as Phentaslim can. We also love its sister product Phentatrim – by far the most effective appetite suppressant we’ve ever seen.

Let’s take a look at what results you can expect when you combine a top-class fat burner with a proven appetite suppressant.

Slim+Trim Key Features

Slim+Trim is the combination of Optimum Nutra’s two most popular products: Phentaslim and Phentatrim. Using these products in conjunction with one another is a sure-fire strategy for losing weight, as one burns fat and the other keeps you feeling full for longer.

Optimum Nutra is one of the most impressive brands we have seen, and not just because they make great products. They offer excellent customer service, provide free delivery, and have a full money-back guarantee on every single order. All of this combines to make them a trustworthy supplement company in our eyes.

They’ve been around for a long time too, which is a rarity in the health and fitness industry. But that just goes to show how popular and effective their products are. Phentaslim has been around for over ten years now and has countless positive reviews from happy customers. Phentatrim came along a little later but it quickly became the top appetite suppressant in the business.

When you buy the Slim+Trim Bundle you even get a nice little bonus in the form of a 150-page eBook. We’ve read through this and absolutely loved it. We’re always a little sceptical of these sort of things as they usually contain nothing but fluff and filler, but we genuinely learnt a lot from this one. It’s a handy guide to losing weight that really helps you understand how fat loss works, so you can keep it off for good.

Slim+Trim Key Points

  • Phentaslim is a thermogenic fat burner
  • Phentatrim is an appetite suppressant
  • Both contain a range of clinically proven ingredients

Slim+Trim Benefits

  • Ingredients are proven to aid fat loss
  • Free shipping and 60-day money-back guarantee
  • You get a free eBook with loads of advice and information

How to Take Slim+Trim

Take two capsules of Phentatrim and one capsule of Phentaslim with two glasses of water around 20-30 minutes before you have your breakfast. Then do the same before your lunch and before dinner.

What does Slim+Trim claim to do?

There are two big obstacles that people struggle with when it comes to losing weight. One is actually burning fat, the other is fighting food cravings and staving off hunger. Phentaslim deals with the first problem, Phentatrim takes care of the second. Between them, they ensure that losing weight is as easy as it could ever be.

The ingredients in Phentaslim raise your metabolic rate, which puts you in fat-burning mode, making it easier to shed the pounds.

The main ingredient in Phentatrim is a soluble fibre called glucomannan. This has been scientifically proven to expand in the stomach, giving you the feeling of fullness. In doing so, this deters you from snacking or overeating and cuts out hunger pangs.

Does Slim+Trim Weight Loss Bundle Work?

It certainly does. The Slim+Trim Bundle works by taking a double-headed approach to weight loss. Phentatrim will ensure you don’t overeat, whilst Phentaslim actually gets you burning the fat away.

There is a lot of scientific evidence backing up the claims behind the Slim+Trim products. Green tea and caffeine are a proven combination for increasing metabolism, and therefore fat loss, which is the main reason why Phentaslim is so effective.

Numerous tests and studies have also been conducted into glucomannan. The results of these show that taking 3g of the ingredient daily will suppress the appetite and lead to weight loss. And that is the exact amount you’ll find in Phentatrim. Some products we have seen don’t contain enough glucomannan for them to work, but that’s not the case here, as Phentatrim contains the optimal dose.

When taken together these products fight fat in two distinct ways, meaning you can potentially double your results!

Slim+Trim Ingredients

There are two main components to the Slim+Trim Bundle: the fat-burning Phentaslim and the appetite-suppressing Phentatrim. Plus, you’ll receive a nice little bonus in the form of a 150-page eBook that is jam-packed full of tips and information to help you get in great shape.

There are several different complexes built into Phentaslim. The main one is all to do with boosting your metabolism and giving you energy. The caffeine and green tea combo is proven to do just this. Cayenne pepper and acetyl l-carnitine help increase metabolism even further, and guarana seed and l-theanine provide extra benefits to your mood and cognition.

Your health and well-being are taken care of through a combination of Ginkgo biloba, Panax ginseng, niacin, and l-tyrosine, with black pepper extract included to aid absorption of the other ingredients.

Finally, there is a vitamin and mineral complex that contains zinc, magnesium, and a whole host of B vitamins.

The key ingredient here is glucomannan (or konjac root, as it is also known). This is a soluble fibre that expands inside your stomach to make you feel full. This stops you overeating and cuts out food cravings. There are plenty of studies to back this up – it has even been approved for weight loss use by the European Food Safety Authority. The recognised dose is 3g per day, which is what you get with Phentatrim.

There is also chromium for lowering blood sugar levels and iodine for thyroid regulation.

This eBook costs £29.00 if you buy it separately, but Optimum Nutra is providing free access to everyone who buys the Slim+Trim Bundle. It contains loads of helpful information about dieting, working out, and getting yourself energised and motivated. Follow the guidelines in this book and you’ll be dropping weight even faster.

Slim+Trim Side Effects?

The ingredients in both Phentaslim and Phentatrim are relatively risk-free, as the formulas have been thoroughly researched for effectiveness and safety. However, Phentaslim does contain caffeine, so if you have a sensitivity you shouldn’t take it too late in the day.

We also stress the need to take Phentatrim with a large glass of water to ensure the glucomannan reaches the stomach before expanding.

Caution: Always swallow the capsules with water. Do not take if pregnant or nursing. If you have any medical conditions (particularly diabetes or thyroid problems) or are taking any medication, consult your doctor before use. Not suitable for anyone suffering from any heart-related health issues, including, but not limited to, high blood pressure. Not suitable for those under the age of 18.

Slim+Trim Customer Feedback

On all of the Independent review sites we’ve looked at, customers seem to be very happy with both Phentaslim and Phentatrim. It’s early days regarding feedback of the bundle package, but there are plenty of positive comments from our own pages for each products, including:

Two weeks ago I was 20st 11.4lbs. Weighing this morning I am 19 st 11.6lbs. 0.2 pounds away from losing a stone in two weeks.

I have drank only water and eaten clean over the two weeks. The pills are amazing for helping to suppress your appetite but I recommend you have a small amount to eat after the 20 min recommendation of taking them or you will experience a weird stomach until some food is digested. The energy I am experiencing from these pills has really helped me down the gym and has finally kicked me into gear for losing weight. I highly recommend these pills for helping towards your overall diet and exercise plan but that’s all it is. A booster for your diet and exercise. You put in the effort and these pills will help you get the most out of what you do. 9.9/10.

I ordered this product mid-April and am really liking it so far! Have lost noticeable weight (that people comment on). I do exercise regularly anyway so haven’t changed anything there, it’s just given me a much needed boost. The only thing I will say is that – as a big caffeine drinker myself – do not drink coffee while taking this product, at first I couldn’t sleep/was feeling a bit jittery. However when I cut the coffee down that all stopped! Good product if taken correctly!

So after a full two month course on these pills, I am very happy to announce that I have lost two and a half stone in two months! I would recommend these to anyone hoping to get a head start on their weight loss as the extended energy, fuller feeling of stomach and ease of use make these HIGHLY commendable.

I received my order in the mail super fast which was awesome. Best of luck to everyone who takes these, they’re great!

  1. Been using this combo prod for a couple of months and have lost nearly 16lbs. This is in tandem with better diet and some exercise so other factors at play with my weight loss. I do find the pills help and my results are better so far than previous attempts in the past.

    I once lost 20lbs years ago but put it back on because I just went back to old habits of sitting around eating junk. It’s these bad habits that need addressing and so far finding the red pills help with this, with energy and that, so I feel I want to get up and move about.

  2. Some Reviews refer to losing a certain amount of “Stones”. Is “stones” a use of Measurement out-side of the U.S. [Foreign Country]? Explain please Not familiar, I live in the [U.S.]. Thank You.

    1. Stones is an imperial measurement, and is equivalent to 14lbs. So, 140lbs would be 10 stones. It’s popular in the UK, where people would say they are 10 stone 9, for example, which is 149lbs.
