Advice & products
Four routes. One of them is yours.
We start with your everyday routine and choose the products afterwards — not the other way round.
Daily essentials
Covered every day.
Two glasses a day. One for the start, one for the night.

- PowerCocktail — in the morning
- Restorate — in the evening
- Activize Oxyplus — across the day
Vitamin C and selenium contribute to the normal function of the immune system.
Weight management
Losing weight that adds up.
One meal with known nutritional values instead of one you have to guess at.

- ProShape All-in-1 — meal replacement
- TopShape — before meals
- C-Balance — before carbohydrates
Substituting two of the main daily meals of an energy restricted diet with meal replacements contributes to weight loss.
Sport
Keep what you build.
For recreational and competitive sport — and for everyone starting again.
- ProShape Amino — 8 essential amino acids
- Restorate — magnesium for the evening
- Activize Oxyplus — before the effort
Protein contributes to the maintenance and growth of muscle mass.
Beauty
Built from the inside.
Skin, hair and connective tissue need building blocks — and vitamin C to put them to use.

- Beauty Drink — collagen & vitamin C
- Women+ — tailored to women
- Cell Protection Antioxy — antioxidants
Vitamin C contributes to normal collagen formation for the normal function of skin.

One day, five moments.
This is what my own day looks like. Yours will look different — which is precisely why we talk first.

New in the range
TopShape.
Three capsules, twice a day.
With biotin, calcium and zinc plus extracts of bitter melon, green coffee bean, white mulberry and ginger. One to two hours before meals, in the morning and late morning.
Biotin contributes to normal macronutrient metabolism and zinc contributes to normal metabolism of fatty acids.

Why I do this.
I am Kerstin. For a long time I was looking for something that fits into my day rather than the other way round — not the next cure and not the next four-week resolution, but something I do in the morning without thinking about it.
At some point I changed three things: more movement, different food — and a daily supply I no longer leave to chance.
What has changed since then I owe to no miracle product, but to sticking with it.
That is exactly why I will not talk to you about four weeks, but about your Tuesday. I look at how your day actually runs and build something that fits into it. Sometimes that is three products, sometimes one — and sometimes I tell you that you do not need anything right now.
I am an independent FitLine distribution partner and I earn something when you order. I would rather say that straight away — and it is the reason I will also tell you when something does not fit.
Magnesium contributes to a reduction of tiredness and fatigue.

Tell me briefly what you want to achieve and what your day looks like. Usually an answer the same day.
