Fresh hawthorn berries - hawthorn berry supplement for cardiovascular support

Hawthorn Berry Extract

Crataegus oxyacantha - traditionally used in European herbalism. Hawthorn berries are rich in oligomeric proanthocyanidins (OPCs) and flavonoids. This botanical has been part of traditional wellness practices for centuries and is one of the most studied plants in the context of everyday circulatory health. CardioX uses a standardized extract for consistency across batches.

Use in CardioX: Traditionally used to support normal heart function as part of an everyday wellness routine.

Vitamin C - Collagen Formation for Blood Vessel Walls

Vitamin C (ascorbic acid) is a water-soluble vitamin with multiple EFSA-recognized functions relevant to cardiovascular wellness. Most notably, vitamin C contributes to normal collagen formation for the normal function of blood vessels. Collagen is a structural protein essential for the integrity and elasticity of vessel walls.

EFSA Claim: Vitamin C contributes to normal collagen formation for the normal function of blood vessels. Also contributes to the reduction of tiredness and fatigue, and to normal immune function.

Magnesium - Normal Heart Muscle Function

Magnesium is an essential mineral involved in over 300 enzymatic processes in the body. In the context of cardiovascular wellbeing, magnesium is recognized for its role in normal muscle function - including the heart muscle. It also contributes to the maintenance of normal blood pressure and to the normal functioning of the nervous system.

EFSA Claim: Magnesium contributes to normal muscle function. Magnesium contributes to the maintenance of normal blood pressure. Magnesium contributes to normal functioning of the nervous system.

Niacin (Vitamin B3) - Normal Blood Cholesterol Levels

Niacin is a B-vitamin with a well-established EFSA-approved function in cholesterol management with food supplements. Niacin contributes to the maintenance of normal blood cholesterol levels - one of the most directly relevant nutrient claims in the context of everyday cardiovascular health for adults.

EFSA Claim: Niacin contributes to the maintenance of normal blood cholesterol levels. Also contributes to normal energy-yielding metabolism.

Vitamin B6 - Homocysteine Metabolism

Vitamin B6 (pyridoxine) contributes to normal homocysteine metabolism. Homocysteine is an amino acid naturally occurring in the body; supporting its normal processing is considered relevant to everyday cardiovascular wellbeing by the nutritional science community.

EFSA Claim: Vitamin B6 contributes to normal homocysteine metabolism. Also contributes to normal energy-yielding metabolism and normal immune function.

Zinc - Immune Function and Antioxidant Defense

Zinc is an essential trace mineral that contributes to normal immune function and to the protection of cells from oxidative stress. Both functions complement the broader cardiovascular wellness formula in CardioX.

EFSA Claim: Zinc contributes to normal immune function. Zinc contributes to the protection of cells from oxidative stress.
