Short answer: direct sticks are convenient without water, while the depot tablet is taken after a meal with fluid. Format does not prove faster absorption or better results. Compare the full daily dose, ingredients, warnings and your routine instead. These three supplements are alternatives and should not be taken together.

What vitamin C and zinc may claim
With sufficient intake, vitamin C, zinc and vitamin D contribute to normal immune-system function. Vitamin C and zinc also contribute to the protection of cells from oxidative stress. These are authorised function claims—not promises to prevent, shorten or treat colds. More milligrams do not automatically mean more benefit.
1. tetesept Zinc 15 Direct: moderate vitamin C, more zinc
tetesept Zink 15 Direkt, 20 Sticks · GTIN 4008491117050. One stick provides 200 mg vitamin C, 15 mg zinc, 25 µg vitamin D3, 55 µg selenium and 50 mg histidine. Take one daily on the tongue. It is for adults; the label says not to use other zinc or vitamin D supplements. Sorbitol may have a laxative effect if overconsumed. Catalogue issue: the live Shopify title says 15 µg, but the manufacturer and pack say 15 mg zinc.

How to choose
Choose a direct stick for water-free use if you tolerate its ingredients, or the depot tablet if you prefer a solid form after a meal. Compare the whole nutrient blend: tetesept also supplies selenium and histidine, while both Doppelherz products supply 1,000 mg vitamin C. Do not choose by the highest number alone.
Safety and important warnings
All three are food supplements, not medicines. Do not exceed the label dose, combine the products, or add other zinc/vitamin D supplements. Keep away from young children and do not use as a substitute for a balanced diet. Seek qualified advice with kidney disease, medicines, pregnancy, breastfeeding or suspected deficiency. The received pack label takes priority.
Common questions
Is DIRECT faster or better than DEPOT?
No. DIRECT describes water-free use and DEPOT the tablet technology; neither proves generally better absorption or effect.
Is 1,000 mg vitamin C better than 200 mg?
Not automatically. A higher label amount is not a quality or effectiveness ranking.
Can I take a stick and tablet together?
No. They are alternatives, and the labels warn against added zinc or zinc/vitamin D supplements.
Do vitamin C and zinc prevent colds?
This guide makes no prevention or treatment claim. The authorised claim concerns normal immune function.
