The formula
Highly bioavailable form bound to natural citric acid
37.5 mg- Magnesium citrate
- Magnesium salt combined with citric acid, offering an optimal balance between bioavailability and digestive tolerance for efficient absorption.
- Magnesium citrate dissociates in the acidic environment of the stomach, releasing easily absorbable magnesium ions. Its molecular structure promotes active transport across the intestinal barrier.
- Authorized claim: Magnesium contributes to the reduction of tiredness and fatigue. Magnesium contributes to normal functioning of the nervous system. Magnesium contributes to normal muscle function. Magnesium contributes to the maintenance of normal bones. (EU Regulation No. 432/2012)
Authorized EU health claim
Essential antioxidant involved in more than 300 biochemical processes
250 mg- Vitamin C
- Water-soluble essential micronutrient that the human body cannot synthesize. Powerful antioxidant involved in collagen synthesis and cellular protection.
- Vitamin C acts as an electron donor in the hydroxylation reactions necessary for collagen biosynthesis. It also participates in the recycling of vitamin E and the neutralization of reactive oxygen species.
- Authorized claim: Vitamin C contributes to normal collagen formation for the normal function of blood vessels, bones, cartilage, skin and teeth. Vitamin C helps protect cells from oxidative stress. Vitamin C contributes to the reduction of tiredness and fatigue. (EU Regulation No. 432/2012)

Citrus concentrate rich in natural bioactive compounds
- Lemon Extract
- Concentrated extract from the Citrus lemon fruit, rich in flavonoids, particularly hesperidin and naringenin, and in bioactive compounds such as citric acid.
- Lemon bioflavonoids work synergistically with vitamin C to strengthen connective tissues. These phytochemical compounds support microcirculation and stabilize the structure of cell membranes.
Natural flavonoid found in many fruits and vegetables
- Quercetin
- Polyphenol from the flavonoid family, widely found throughout the plant kingdom. Present in onions, apples and many colorful fruits.
- Quercetin has a molecular structure that allows it to modulate various biochemical pathways. It interacts with cell membranes and influences intracellular signaling pathways involved in the response to oxidative stress.
Nordic berry concentrated in anthocyanidins and proanthocyanidins
- Blackcurrant extract
- Extract from Ribes nigrum berries, a shrub native to Northern Europe. Naturally rich in anthocyanins, flavonoids and vitamin C.
- The anthocyanins in blackcurrant act as antioxidants by neutralizing free radicals and preserving the integrity of cell membranes. These polyphenols interact with various enzymes involved in the metabolic pathways of cellular stress.
Standardised extract rich in phytosterols and essential fatty acids
50 mg- Pumpkin seed extract
- Concentrate obtained from Cucurbita pepo seeds, standardized to 0.5% β-sitosterols. Traditional source of phytochemical compounds and essential micronutrients.
- The β-sitosterols and other bioactive compounds in pumpkin seeds interact with cellular receptors and metabolic pathways. Their molecular structure, similar to certain natural steroids, promotes their integration into various biochemical pathways.
Standardized Indian frankincense resin with high concentration of active ingredients
40 mg- Boswellia serrata
- Extract from the resin of Boswellia serrata, a tree native to India. Traditionally used for thousands of years in Ayurvedic medicine.
- Boswellic acids interact with various enzymes including 5-lipoxygenase, thus modulating the production of leukotrienes. This biochemical action influences metabolic pathways related to normal cellular response to environmental stress.
Essential coenzyme involved in more than 400 biochemical reactions
15 mg- Vitamin B3 (Niacin)
- Water-soluble vitamin from the B group, also known as nicotinic acid. Crucial component of the NAD and NADP coenzymes, involved in numerous cellular redox reactions.
- Niacin participates in cellular respiration processes as a component of the NAD and NADP coenzymes. These molecules facilitate the transfer of electrons in the mitochondrial respiratory chain and are essential for energy metabolism.
- Authorized claim: Niacin contributes to normal energy-yielding metabolism. Niacin contributes to the normal functioning of the nervous system. Niacin contributes to normal psychological functions. Niacin contributes to the maintenance of normal mucous membranes. Niacin contributes to the maintenance of normal skin. (EU Regulation No. 432/2012)

Hay fever, pollens, grasses
Spring and summer mean sunny days and good times. But not for everyone... For some, they bring dry throat, red eyes, runny nose and tiredness.
These discomforts are caused by seasonal allergies like hay fever, pollen or grass allergies.
Istanat is a natural food supplement made with plant-extracted Quercetin, blackcurrant, lemon and red onion extracts, pumpkin seeds, boswellic acid, vitamin C, vitamin B3 and magnesium.
Istanat works differently than standard hay fever medication—composed of natural ingredients, it doesn't directly target symptoms.
Instead, it provides essential micronutrients to the body and helps support the proper functioning of the immune system to help prevent these discomforts from developing.
