How is an elixir like this usually taken, and is it suitable for taking as a course?

The water-alcohol extract format is convenient because the active compounds are already in liquid form and disperse easily in water; the elixir is usually added to a small amount of water. This is a common format for mushroom extracts, especially when the product is designed to be taken as a course rather than as a one-off.

Supplements like this are most often considered during specific periods:

• the colder months and the season of colds;
• a heavy workload and a busy schedule;
• irregular rest;
• a recovery period after overexertion.

The exact recommendations on amount, frequency and duration are always given by the manufacturer on the packaging, and these are what you should follow. If you take medication or have chronic conditions, it is better to discuss using the supplement with a specialist in advance.
