How are we different?

Our Cardio Protect contains vitamin B1 to support normal heart function and is a meticulously crafted blend of over 30 carefully selected vitamins, minerals, amino acids, and plant compounds. This unique formulation was developed in collaboration with Dr. Ralf Heinrich, a medical practitioner specialising in natural therapies and the head of THERA Praxisklinik. Our premium complex encompasses a wide range of valuable plant compounds and extracts, including schisandra berry extract, blueberry extract, olive leaf extract, green tea extract, bamboo extract, black seed extract, black garlic extract, ginkgo biloba extract, resveratrol, taxifolin, rutin, hesperidin, lutein, and zeaxanthin. Notably, our blend also incorporates SOD enzymes derived from freeze-dried melon juice concentrate, as well as catalase.

In addition, our premium blend features a vitamin B complex consisting of thiamine HCl (vitamin B1), highly bioavailable flush-free nicotinamide (vitamin B3), directly bioactive coenzyme form P5P (pyridoxal-5-phosphate) of vitamin B6, patented premium ingredient Magnafolate® Pro with bioactive L-methylfolate (L-5-MTHF) as vitamin B9, methylcobalamin (Vitamin B12), and ascorbic acid (Vitamin C). We have also included microencapsulated all-trans vitamin K2 MK7, which is highly active and protected against degradation, as well as natural vitamin E sourced from sunflower oil.

Additionally, our functional blend incorporates essential minerals such as iron, magnesium, zinc, and copper in the form of high-quality amino acid chelates, including iron glycinate, magnesium glycinate, zinc lysinate, and copper bisglycinate, known for their superior bioavailability. We have also included trace elements such as organic L-selenomethionine (selenium), chromium picolinate (chromium), and boron. Completing the blend are the amino acids N-acetylcysteine and L-carnosine, along with TMG-betaine, which serves as the activated form of choline.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.
