OptiSlim VLCD Classic Series

Bought a box of 21 vanilla shakes on Tuesday and had the first one at lunchtime yesterday .. omg, this has the most disgusting taste ! I mixed it with milk in a shaker beaker and it was lumpy and vile. Today I put it in a blender with some vanilla essence and it blended better, but the taste was still disgusting. Also by 4pm, I’m starving and have to have an early dinner .. so much for filling you up .. total rubbish UGH ! Show details

AWFUL taste, it's like you've crushed up tablets of some sort and added them, that's how it tastes, what a waste of money, be useful to be able to buy single sachets to try it first Show details

Mix together for perfect combo- Optislim banana too sweet, isowhey choc not sweet at all – Okay, this is a bit unusual because it’s a mix of half the optislim banana flavour & half the Isowhey chocolate flavour….stay with me!….i find optislim too sweet & Isowhey chocolate with no sweetness at all….even though I love that’s its low in sugar but with a super chocolatey flavour. Being on a liquid diet when you dread drinking the shakes… Read more ·  2

really makes it hard to stick with it. I like banana flavour & I like chocolate so I figured I’d mix the 2 together & maybe it would balance the level of sweetness. Add to the mix ice cold water & I got a flavour I loved & actually look forward to. I keep the amount of water I need in the fridge with ice cubes in there to make sure it’s as cold as possible without being frozen. Obviously everyone’s tastes are different but if you love choc/banana flavour & it’s the sweetness that’s making it hard to stomach, I hope this helps. Also, I use a shaker with a metal spring ball in there which helps with shaking up the mixture & disolving the powder. The shaker is quite large (holds a 800ml) so it really helps with shaking it up well. I hope this helps someone who’s trying to decide on the flavour. I only started this today (14th July 2924) so I will give an update in a week to let you know how I’m faring with the flavour & my weight loss. FYI I’m a 5’4 50+ female with starting weight 84.5. Good luck!

Good product with a lot of flavour choices BUT you have to be ruthless in what you eat – I used 1 pack a day as a meal replacement for the first week- usually in the mornings. In the past I have had issues with using the shakes and bars. They left me running to the loo and I found the only way I could deal with the taste was by mixing them with full cream milk. My mistake - it made me put on weight and I was always hungry. May 2024… Read more

-Well this time things are different for me. I bought the variety pack and just buy a small pack of ten (lifestyle ones - choc/ mint, caramel, honeycomb) weekly to add whatever flavour I want to the variety box. I put ice into the shaker and add cold water. I use one shake a day for mid morning / lunch and I skip breakfast. I walk for 1 1/2 to 2 hours with the dog every morning and If I am hungry when I get home I will have toast with butter and jam. I have 1 cup of coffee with full cream milk and 1 sugar a day (my treat) and I have a healthy meal for tea. Well a month ago I started back on the shakes as I had a dental problem and could not eat. I needed something with protein and vitamins to help while going through dental treatment. For the past month I have only had 1 shake and 1 cup a soup a day. It is all I can eat. I am under dental care so am on antibiotics as well. In the past month I have lost 8 kg. So these shakes do work if you limit what you eat drastically. This means no fried food, no takeaway, no cake, no bisciuts, no packages potato chips, no lollies, no chocolate, no desserts - get the picture (NO FUN). But this time I am not hungry, no constant trips to loo and I can see the weight coming off. My clothes are too big for me now and I am buying some new tops as I go. Weight at start 98 KG weight now 90 KG I don't like the chocolate / mint flavour it tastes like chemicals. The expresso one is very grainy and bitter so unless you really like savoury flavours you wont like the expresso one at all.

Extremely happy - I've lost 17kg in four months – Optislim has a range of flavours in its shakes - I prefer French Vanilla, which to me is slightly better than the Royal Chocolate. The big problem with diet shakes - both Optislim and Optifast - is they don't dissolve easily or completely. Optislim's French Vanilla seems the best in this regard - and it is a flavour I am not getting bored with.… Read more

You can buy an Optislim brand shaker (which works very well), but Optifast which needs a bigger volume shaker does not offer any sort of shaker at all - quite annoying! I have been on two meal-replacement shakes a day, plus one small meal and snacks - with a daily calorie target of 1,000 calories a day. I have lost about 17kg in about four months - so the meal-replacement system really does work. My surgeon has told me I need to lose 20kg (18 percent of body mass) - so I am well on track to meet this target. Another plus for Optislim is that, since it is sold by supermarkets, you can get very good specials with discounted prices from time to time. I wouldn't both with buying the high-protein bars of any brand. I am not keen on the taste of any of them - and you get the same protein level and calories with a shake.

I tried a few of the shakes and I love everyone. Not only did I lose 4kg but my sugar levels have dropped to 7.4, also my cholesterol has dropped. My doctor is really pleased with my results. Of course, I had to do a lot of walking and watch what I eat. I will definitely buy some more.

great no complaints here – seriously dont know why everyone is complaining i mix mine with ice cubes blends well lovely to drink. If to sweet add a bit more water. i like these better than optifast they make my lips sticky. i lost 5.5 kg in 14 days pretty chuffed with results. Show details

So far so good – I have no problem with the shakes or flavors. I wish they were less sweet, otherwise there is no 'fish/salt' taste or smell. Shake/blend it correctly & it won't be grainy. Seeing that i have lost 4 kg within the first 2 weeks, I am thrilled. If you want to lose weight, honestly, stop whinging, stick with the program. It works Show details

I tried the new mango shake and was so disappointed. The flavour is hard to describe as mango and it does not blend well leaving a floury texture that i have not experienced with other optislim shakes. I will not purchase again and will have to force myself to use these shakes. So VERY disappointing Show details

Won't be buying again. Non smoker and non drinker and after changing from opftifast while hospitalised, I have found I have put on weight and this stuff is disgusting. I bought a variety pack and there was no strawberry in it, but all the other flavours are horrible. I definitely will not be wasting my money on something I don't enjoy at all. Show details

Nope. Just nope – These shakes were beyond disgusting. I was a big fan of the premium ones, and mistakenly purchased the regular range. I had one sip and tossed. I know these are not actual chocolate shakes and some concessions will need to be made, but these are not drinkable. I contacted customer service but as they were not purchased direct and were through… Read more

chemist warehouse they said I was not eligible for their 30 day satisfaction guarantee.

So, I'm not satisfied, and buyer beware.

Do not make the same mistake, spring for the "premium" and stay away from their standard range unless you like throwing away money.

I started on these again to shift weight gained from grief at losing my partner to pancreatic cancer. I add frozen berries sometimes and also other different fruits to the shakes to really mix them up. Sometimes I use the shakes to make healthier… Read more

muffins. I am beginning to lose weight and also exercise daily : walking running and work out with weights and mobility. I am also in remission for synovial sarcoma cancer. Love all the flavours! Will keep on buying as they are helping me.

Who actually likes this? – I don’t usually mind a meal replacement shake. This stuff was so foul. Not vanilla tasting - hard to describe. Tastes like liquid plastic. Watery. Could not get half way before it went down the sink. Show details

Tastes like milk with vitamins in it and is runny so you don’t feel full – I got these by accident so had to try them. They are revolting in texture and flavour. But I thought I bought lite ones nope I didn’t and I got them to send me samples and they are revolting too. Maybe if I hadn’t tasted the optifast ones I wouldn’t have cared as much but. There’s just no comparison. All the flavours taste the same with an… Read more

aftertaste of something chemical. They are runny in texture so it’s like a plain glass of gross milk with vitamins in it. Yuck!!! Waste of money

Dear karen – People complaining about taste, try a pea protien shake a day before starting this, then taste won't be a worry lol seriously, I can't stand seafood and get no fish taste at all, it tastes best fully blended with abit of ice, also you can't expect something that's so good for you to taste like Starbucks or thickshake (confused black girl meme) it's seriously not that bad, get a better blender maybe Show details

AVOID – Not only is the shake awful but so s their customer service I bought with PayPal. Item arrived with one box damaged so I contacted company and they said they sent a replacement, they didn’t and wouldn’t provide tracking. Then I logged paypal dispute and they lied and said they sent the replacement when they didn’t. They provided the original… Read more

tracking number for the damaged item that I had to bin. Disgusting service, terrible company service. Now I have to call PayPal to try to explain what they have done and that the tracking they gave them is not the replacement it’s the original order.

Early days, taste pretty good – I have just started drinking these, I've bought the variety pack. I have tried vanilla, chocolate, & banana so far. Honestly I don't know why some reviews say they taste bad, or don't dissolve... because all flavors I have tried so far are pretty good and dissolve very well with just water. Maybe they changed the formula since I've purchased or some people are that picky? Yet to see if I lose weight yet as its been only 2 days. Wish me luck. Show details

Great taste, great customer service, really effective! – I have tried the Lady Shake, Fat Blaster, and now Optislim. Optislim is leagues ahead in terms of taste, texture and the amount of time that it keeps me full for, I've been drinking the chocolate sachets since April 2023 and they helped me lose 23kg last year! The Chemist Warehouse I buy them from has a "buy 2 boxes for $65" deal pretty… Read more

consistently that means each sachet works out at just $1.54 per meal!

I opened a fresh box a couple weeks ago and was appalled by the taste and smell of it, super shocked, so I emailed the customer service line and heard back from them fairly soon :) They asked me to post 2 sachets to a reply paid address and they assessed them and agreed with me that there had been a dud batch, and will be sending replacement boxes out swiftly! Excellent customer service I'd say, along with a product I've been enjoying for nearly a year now.

Changed Flavour – The product has lost its density, lost the chocolate flavour and has an odd almost fish taste Once I've gone through the packet, they have lost my patronage Show details

Only like the espresso – Have been using the product for years. Tried all of the flavours but find I only like the espresso. It's not fabulous, doesn't taste like a milkshake but it's acceptable. Originally used it to lose weight, along with lite n easy which I successfully did. Now I just have it at lunch and eat normally at night. This has maintained my weight for years. Recommend for people who are are serious about losing weight. Show details

YUM - Buy – This may be my greatest discovery. It’s literally a strawberry Freddo in liquid form with all the nutrients my malnourished ironless organs harass me for. Slay Show details

Way too sweet 20g of sugar – For sometime that is meant to promote weight loss this has way too much sugar in it 20g of sugar you might as well drink soft drink. I like that it has vitamins and minerals added to it but I'm switching to another brand with less than half the sugar. Show details

Gritty and very, very sweet – I bought the 21 sachet box. Now matter how much I mix it, with a shaker, an immersion blender or even making it with hot water it is still gritty. It has a strong rather bitter espresso flavour but it is far too sweet. I am used to brands with a similar calorie count which unfortunately are not easily available in Australia or NZ, eg Lighter… Read more

Life, Cambridge Diet and my favourite Exante, and their shakes are much more creamy and mix better. Their soups are also superior . Yes, you will still lose weight if you use Opti products but the quality and experience is not as good. My advice is to shop around for different brands if they are available. If you want to try Optislim get a variety pack rather than being stuck with a box of this flavour.

Good Aussie product that works – have been using some other products but thought I would give these a try as they were a decent price. I had read quite a few negative reviews regarding the taste.. I can say there is absolutely nothing wrong with the taste and anyone saying they are awful have obviously never tried some other brands. They are a convenient option and will work if… Read more

used correctly. I replace 2 x meals per day and have a healthy normal meal for dinner. Regular exercise will also help you get to your goals faster. I recommend getting the variety pack first up to see what flavours you like most. I just happen to like them all! Absolutely no negative side effects either.
