Strong immunity from within: developed and produced in the Netherlands

The Better Immunity bundle contains three essential supplements that together provide a complete support program for your immune system: Vitamin D3 + K2 (50/75) (cholecalciferol + menaquinone-7 for optimal calcium metabolism), Vegan Mushroom Mix BIO (seven organically certified mushrooms with broad spectrum of polysaccharides) and Calcium Ascorbate Powder (buffered, stomach-friendly vitamin C). This bundle has been carefully composed by Paul Klein Breteler and is fully produced in our own FSSC 22000-certified facility in the Netherlands.

With a focus on synergy between vitamins D, K and C, complemented by natural plant compounds such as beta-glucans, this bundle offers holistic support for daily protection. Thanks to the scientifically supported combination, you work with this bundle on a strong and resilient immune system.

Why this bundle works

The power of the Better Immunity bundle lies in the synergistic action of three complementary products. Vitamin D3 + K2 work together for optimal calcium metabolism: D3 plays a role in the absorption and utilization of calcium and contributes to the normal function of the immune system, while K2 (MK-7) contributes to the maintenance of normal bones and supports normal blood clotting.

The Vegan Mushroom Mix BIO combines seven organically grown mushrooms (Agaricus blazei, Cordyceps sinensis, Maitake, Reishi, Lion’s Mane, Zhu Ling and Turkey Tail) with a broad nutrient profile of polysaccharides (beta-glucans), glycoproteins and all essential amino acids. Calcium Ascorbate Powder delivers buffered vitamin C that is pH-neutral and stomach-friendly, while it contributes to the normal function of the immune system and reduces tiredness and fatigue.

This holistic approach combines vitamins, minerals and plant extracts for daily protection – exactly as Paul Klein Breteler intended.

What’s inside the Better Immunity Bundle?

1. Vitamin D3 + K2 (50/75): synergistic combination

Vitamin D3 + K2 combines cholecalciferol (vitamin D3) with menaquinone-7 (vitamin K2, MK-7) for optimal support of calcium metabolism and bone health. Vitamin D3 plays a role in the absorption and utilization of calcium, contributes to the normal function of the immune system and supports normal muscle and bone function. Vitamin K2 (MK-7) contributes to the maintenance of normal bones and supports normal blood clotting.

Composition per capsule:

• 50 mcg vitamin D3 (cholecalciferol) = 2,000 IU (1,000% NRV)
• 75 mcg vitamin K2 (menaquinone-7, MK-7) (100% NRV)
• Synergistic combination for calcium metabolism
• Contributes to normal function of immune system
• Supports bones and muscles
• Plant-based HPMC capsules

Vegan Mushroom Mix BIO combines seven organically certified mushrooms in a 1:1 water extract. These mushrooms (Agaricus blazei, Cordyceps sinensis, Maitake, Reishi, Lion’s Mane, Zhu Ling and Turkey Tail) offer a broad nutrient profile with polysaccharides (beta-glucans), glycoproteins, vitamins and all essential amino acids. SKAL-certified organic, free from pesticides, heavy metals and chemical residues.

Composition per capsule:

Composition per gram (1 scoop):

• 900 mg vitamin C (1,125% NRV)
• 70 mg calcium (9% NRV)
• pH-neutral and stomach-friendly
• Contributes to normal function of immune system
• Reduces tiredness and fatigue
• Increases iron absorption

Scientific background

The Better Immunity bundle is based on scientific insights about nutrient synergy. Vitamin D3 and K2 work synergistically together: D3 has a function in the absorption and utilisation of calcium, while K2 (MK-7) contributes to the maintenance of normal bones. This combination supports optimal calcium metabolism.

The seven organic mushrooms in the Mushroom Mix contain naturally occurring polysaccharides including beta-glucans. Each mushroom type has a unique profile of bioactive substances, and together they offer a broad spectrum of plant compounds and all essential amino acids.

Calcium ascorbate is a buffered form of vitamin C that is less acidic than ascorbic acid (pH-neutral), making it more stomach-friendly at higher dosages. Vitamin C contributes to the normal function of the immune system and reduces tiredness and fatigue.
