How to make Sirtfood Green Juice

Sirtfood Green Juice


  • 75 grams of kale (2 large handfuls)
  • 35 grams arugula (1 large handful)
  • 5 grams of parsley
  • 5 grams of lovage
  • 2 – 3 sticks of celery, including the leaves (about 150 grams)
  • 1/2 medium apple
  • juice of 1/2 lemon
  • 1/2 level teaspoon matcha powder


  1. Put all the ingredients in your juicer except for the matcha powder. In any case, use a juicer and not a blender or smoothie maker.
  2. Only the juicer ensures you are consuming the required amount of sirtuin-activating botanicals.
  3. If you don’t have a juicer yet, you can use the info box below to get a recommended juicer from Amazon, which costs around 80 euros and which I use myself.
  4. If you have juiced all the ingredients, about 250 ml of liquid (juice) should have been extracted from it. Mix a small amount of the juice with the matcha powder and mix well so that nothing clumps.
  5. Then pour in the remaining juice and stir well again. Serve the juice in a tall glass and top with some grated parsley, if you like.
  6. And your green Sirtfood juice is ready.

Tip for winter months October to April against colds: During these cold months, add an additional 15 grams or more of ginger to your Sirtfood juice and increase the lemon content from 1/2 lemon to the juice of a whole lemon. This will increase and improve your immune defenses. So you are better immune to colds and flu viruses. In these cases, you may ignore the extra calories. You will lose weight just the same and increase your protection at the same time!

However, if you cannot get an ingredient fresh, simply use unprocessed frozen products. Kale in particular is not always available fresh. There is nothing to be said against the frozen alternative. If you need to, you can also substitute kale with savoy cabbage or spinach.
