Description

Comprehensive support for cellular protection, circulation and well-being

Our SpikeFORTE with an enhanced formula combines three highly effective ingredients – curcumin, astaxanthin and high-dose nattokinase with 5,000 FU per capsule – complemented by piperine for improved bioavailability. This powerful combination is designed to help protect the body against oxidative stress, support healthy circulation and promote overall well-being.

Of particular interest: Studies suggest that these active ingredients may not only help reduce inflammation in the body, but are also being investigated in current research for their potential role in naturally supporting processes associated with atherosclerosis. There is also evidence suggesting a potential contribution to natural blood thinning.

Effects

Curcumin – natural support against oxidative stress

Curcumin is the primary bioactive compound found in turmeric (Curcuma longa). Studies have reported reductions in inflammatory markers such as CRP and IL-6, as well as positive effects on vascular function. In this context, curcumin may help reduce inflammation in the body and address factors that play a role in approaches aimed at naturally supporting the management of atherosclerosis.

  • Helps reduce inflammation in the body through antioxidant and regulatory effects on inflammatory markers [1] [2] .
  • Vascular health and endothelial function are supported [3] .
  • Synergy with piperine for significantly improved bioavailability [4] .

Nattokinase – an enzyme with a long tradition in Japan

In SpikeFORTE with an enhanced formula, we use high-dose nattokinase with 5,000 FU per capsule, obtained through the fermentation of soybeans (natto), a centuries-old tradition in Japan. Research has identified properties that may help maintain healthy blood flow. On this basis, nattokinase is frequently discussed in the context of natural blood thinning.

  • Natural blood thinning through fibrinolytic activity and effects on coagulation markers [3] [5] .
  • Vascular health and mild blood pressure support in controlled studies [6] .

Astaxanthin – powerful antioxidant from microalgae

Astaxanthin is a red carotenoid derived from Haematococcus pluvialis. It protects cell membranes against oxidative stress and supports skin and eye health. These effects are relevant when addressing factors that play a role in approaches aimed at naturally supporting the management of atherosclerosis and reducing inflammation in the body.

  • Cellular protection and reduction of oxidative markers in human studies [7] .
  • Skin elasticity, hydration and protection against UV-induced stress [8] .
  • Vascular-related markers, such as inhibition of LDL oxidation, may be positively influenced [7] .

Piperine – the absorption enhancer

Piperine from black pepper improves the absorption of substances with otherwise limited bioavailability. Human studies have shown a significant increase in curcumin bioavailability. This enhances the overall effectiveness of the formula, particularly when it comes to reducing inflammation in the body and supporting vascular-related processes [4] .

Why this combination?

  • Curcumin + Astaxanthin for comprehensive antioxidant protection and support for balanced inflammatory processes.
  • Nattokinase to support natural blood thinning and healthy blood flow properties.
  • Piperine enhances bioavailability and helps maximize the synergistic benefits of the formula.

The result is a carefully balanced formula that protects cells, supports healthy circulation and helps reduce inflammation in the body.
