Slenderiiz: How the Partner.Co Weight Management Programme Works
The Slenderiiz programme is Partner.Co’s flagship product for body weight management. I have used it personally and guided my team through it since becoming an IBP in 2019.
I have been a Partner.Co Independent Brand Partner since 2019, and in Italy this is the question I receive most often: “Does it really work? How do you use it? How much weight can you lose?”
I answer everything honestly in this guide.
In brief
- Slenderiiz combines day/night drops, the PureNourish meal replacement shake and, optionally, Giving Greens.
- In the first 1-2 weeks, the drop is mainly linked to fluids; real fat loss usually starts from the third week.
- With consistency, my team reports an average of 0.5-1 kg per week from the third week, up to 5-8 kg in 3 months.
- It is not a crash diet: anyone promising 10 kg in 2 weeks is not telling the truth.
What is Slenderiiz?
Slenderiiz is not a “magic diet”. It is a weight management support system made up of:
- Day and Night Drops: two separate formulas for daytime and night-time metabolic support
- PureNourish: a protein shake that replaces one meal with a balanced nutritional profile
- Giving Greens (optional): a green vegetable powder to supplement micronutrients
The system works on three fronts at the same time:
- Metabolism: the drops support metabolic function
- Satiety: the shake helps reduce hunger and maintain energy
- Nutrition: it helps ensure the body receives what it needs even in a calorie deficit
If you want more detail on the ingredients and reviews of the drops, I have written a dedicated guide: Slenderiiz day and night drops: ingredients and how they work ->.
How to use Slenderiiz step by step
The Day Drops
When: in the morning, before breakfast, or at most with breakfast.
How: 10 drops under the tongue, leave them to dissolve for 30-60 seconds, then swallow.
Expected effect: support for energy and metabolism during the day. Do not expect an immediate “kick”: the effect is gradual and cumulative.
The Night Drops
When: in the evening, at least 30 minutes before going to bed.
How: the same method as the day drops: 10 drops under the tongue.
Expected effect: the night drops support night-time recovery and metabolism during rest. The body burns calories even while sleeping, and this is the window Slenderiiz Night helps to optimise.
The PureNourish shake
When: as a meal replacement, for breakfast or lunch - you choose.
How: 2 scoops of powder in 250-300 ml of water or plant-based milk. Blend or shake well.
Calories: around 130-150 kcal per serving, significantly less than a normal meal.
Flavour: vanilla, the classic. You can personalise it by adding fruit or coffee.
Nutrition
Slenderiiz is not a rigid diet. The general guidelines are simple:
- Reduce refined sugars and processed carbohydrates
- Increase protein and vegetables
- Eat normally, without starving yourself: the system works best with an active metabolism
There are no “forbidden foods”. The kit includes a complete nutrition guide.
What results can you expect from Slenderiiz?
This is the most important part, and the part where I am most honest with you.
Weeks 1-2: most people notice less abdominal bloating and often a loss of 1-2 kg linked to the elimination of excess fluids. This is not “lost fat”: it is the body’s first response to a change in eating habits.
Weeks 3-6: more gradual and sustainable weight loss begins. On average, 0.5-1 kg per week for those who follow the guidelines, based on my team’s feedback and not on controlled clinical trials.
Months 2-3: people who stay consistent see clearer results. I have supported people who lost 5-8 kg in 3 months with Slenderiiz and appropriate nutrition.
What NOT to expect: losing 10 kg in 2 weeks. Anyone who promises you that is lying.
If your motivation drops during the first few weeks, it does not mean you are doing something wrong: it is normal. I have collected the strategies that genuinely work in this article: Motivation to lose weight: 6 proven strategies ->.

Frequently asked questions about Slenderiiz
Does Slenderiiz really help you lose weight?
Yes, but not on its own: it works as support for metabolism and satiety within an appropriate eating pattern. In the first two weeks, the drop is mostly linked to fluids; real weight loss, from the third week onwards, averages 0.5-1 kg per week for people who follow the guidelines consistently.
How long do I need to use it before seeing results?
The first signs, such as less bloating and less hunger, can appear as early as the first week. For measurable weight loss, allow at least 3-6 weeks; the clearest results, 5-8 kg, are what I typically see after 2-3 months of consistent use.
Do the day drops and night drops do the same thing?
No, they have different functions: the day drops support metabolism and energy during the day, while the night drops support recovery and metabolism during rest. You can find the ingredient and dosage details in the dedicated drops guide.
Who should not use Slenderiiz?
People who are pregnant or breastfeeding, people with metabolic or thyroid conditions, and people taking anticoagulants or specific medications should not use it without first consulting their doctor. Slenderiiz is a food supplement, not a medicine, and does not replace medical advice.
Does Slenderiiz require a strict diet?
No. The guidelines are simple: reduce refined sugars and processed carbohydrates, increase protein and vegetables, and eat normally without starving yourself, because the system works best with an active metabolism. There are no “forbidden foods”: the kit includes a complete nutrition guide to follow as support, not as a restrictive diet.
