Frequently Asked Questions

What effects do the products have?
Food supplements are subject to food legislation. This means we are only permitted to provide very limited information to “normal consumers” about the health aspects of our products and their ingredients. Find out more about this on our website under Legal issues. “Consumers”, in this sense, refers specifically to customers who do not belong to any particular group of medical specialists. Doctors, alternative health practitioners or nutritional therapists, for instance, who are familiar with and use our products, can give you more comprehensive information. If your therapist has not heard of TISSO before, feel free to mention us to him or her.
Do I get a quantity discount at TISSO?
If you order 6 or more units of a product, you will receive a 20 % discount and free* delivery. The same applies for our subscription deliveries. *For deliveries in Germany (for other countries, see payment and delivery)
Can I also obtain products as a subscription delivery?
You can also order products that you require regularly in a practical monthly or quarterly subscription. We will supply you with your desired quantity with free delivery* at your selected interval, and you will save up to 20 % compared to a single order. You can set up a subscription simply via our ordering service or via the respective product order field in our online shop. The subscription deliveries have a flexible term and can be cancelled at any time without notice. *For deliveries in Germany (for other countries, see payment and delivery)
What is the shelf life of the TISSO products?
The most TISSO products have a shelf life of 24 months (unopened). Exceptions:
  • Pro EM san / pur / Berry: shelf life 12 months
  • Pro Vita D3 Oil: shelf life 12 months
Please note the sell-by date of the products.
What size are the product capsules?
Most of our capsules are size 0 (2.16 cm × 0.75 cm). Exceptions:
  • Pro Agalostrum: size 00 (2,30 cm × 0,84 cm)
  • Pro Q10 Plus: size 1 (1,94 cm × 0,68 cm)
  • Pro Dialvit Kids: size 3 ( 1,57 cm × 0,57 cm)
  • Pro Iodine: size 1 (1,94 x 0,68 cm)
What are the capsule shells of the products made of?
We use high quality and well tolerated capsules made from vegetable cellulose (HPMC) or pullulan -without carrageenan, polyethylene glycol (PEG) and other unnecessary or questionable ingredients. Our capsules are free from gelatine and other animal ingredients.
When should I take these products?

Unless indicated otherwise on the packaging, take all food supplements by  TISSO at least half an hour before a meal with about 200 ml of still water.

What are nutrient reference values (NRVs)?
The NRVs (Nutritional Reference Values) in our nutrient tables are EU-wide guideline values for the daily intake of vitamins and minerals. They are used for uniform nutritional labelling and are not identical to the recommendations of the DGE. The reference amounts are based on the requirements of healthy people of normal weight. Age, gender, diet and other individual factors are not taken into account in the values.
What are International Units (IU)?
This is something referred to with some of our products that are rich in vitamins. International units (IU) are units of measurement of the active ingredients defined by the WHO for certain substances – e.g. antibiotics, insulin and even some vitamins. They ensure uniform dosages for products or compounds that are differently effective within the same substance class. The relation between the international unit and the amount of substance differs with each substance. For example: Vitamin A is a collective term for several chemically-related compounds with a different vitamin A activity. The IE given for vitamin A always refers to the retinol compound: 1 IE vitamin A is the equivalent of 0.3 microgrammes of retinol. A daily dosage of our Pro Vita D3 Forte contains 220 microgrammes of vitamin A in the form of retinyl palmitate, which is 400 IE or corresponds to 120 microgrammes of retinol. For instance, in order to achieve 400 IE via the vitamin A precursor beta-carotene, 720 microgrammes of the product would be needed. For some substances there are now additional, more up-to-date units of measurement. For instance, the active ingredient for vitamin A is also provided in retinol equivalents and the one for vitamin E in tocopherol equivalents.
How do I store the products?
All products should be stored in a cool and dry place, away from the light.

Refrigerate - yes
We recommend storing in a fridge at max. 7°C for:
  • Pro EM san / pur / Berry
  • Pro Omega Ultra
Refrigerate –no:
We do not recommend storing our powdered products in the fridge, as moisture from condensation could adversely affect the quality of the product.
Are TISSO products also suitable for vegetarians and vegans?
Apart from a few exceptions, most of our products are suitable for a vegetarian or vegan diet. The following table displays at a glance which TISSO products are vegetarian or vegan and which products contain animal ingredients: Product information vegetarian-vegan
