CAN YOU TAKE SEVERAL MUSHROOMS AT THE SAME TIME?
Yes, in principle it has no contraindication. When the health professional prescribes different types of extracts already considers this option. Sometimes, the synergistic effect of different extracts power isolated effects.
WHAT IS THE DIFFERENCE BETWEEN POWDER AND EXTRACT?
WHAT IS THE DIFFERENCE BETWEEN POWDER AND EXTRACT?
To obtain the extract, we use a different process that produces a highly concentrated powder rich in natural active nutrients such as beta-glucans, terpenes, ergothioneine, fatty acids, ergosterol, hericenones, grifolan, etc.
At Hifas da Terra, thanks to our R&D team, we develop sustainable extraction techniques, such as Hifas Green Extraction TechnologyⓇ, which allows us to obtain pure mushroom extracts with high concentrations of active biomolecules and active ingredients. Due to their more concentrated nature, the extracts provide greater potency and efficacy in their therapeutic action. This allows us to formulate in such a way that the optimal dose is achieved with fewer capsules per day, obtaining results in a shorter period of time.

IS IT NECESSARY TO TAKE ‘BREAKS’ OR CAN I TAKE THE PRODUCTS CONTINUOUSLY?
It is not necessary to take breaks. Both extracts and pure Hifas mushroom powders can be taken continuously as they do not cause any unwanted side effects: they are food supplements which, as their name suggests, complement a healthy lifestyle. However, the duration of use will be indicated by the healthcare professional who prescribes the treatment.
