Kale

History of Kale

Kale, a cruciferous vegetable related to cabbage and Brussels sprouts, has a long history of cultivation dating back over 2,000 years. Initially cultivated in the Mediterranean region, it has been a staple food in various cultures, including Roman and medieval European societies. 

Kale gained prominence in the supplement industry when its juice form became recognised for concentrated nutritional benefits. Its surge in popularity is in part due to the ‘superfood’ trend, making it a sought-after ingredient in the modern health-conscious era.

Scientific Makeup

Kale is a nutrient powerhouse, rich in vitamins A, C, and K. The green leaves also contain valuable minerals like calcium, potassium, and magnesium. When juiced, these nutrients are concentrated, making kale juice an even more potent source of nutrition.

Furthermore, kale juice contains antioxidants, such as quercetin and kaempferol, which are known for their potential health benefits. The phytonutrient profile of kale juice makes it an ideal candidate for various supplement formulations.

 

Benefits of Kale

Kale juice’s nutrient-rich profile affords it a plethora of health benefits. This study demonstrated its effectiveness in lowering blood pressure and cholesterol levels.

Another noteworthy aspect is its rich antioxidant content, which can assist in neutralising free radicals in the body, thus potentially reducing inflammation and cellular damage. 

Moreover, the high levels of vitamins A and C in kale juice are instrumental in supporting the immune system.

The vitamin K content is particularly impressive, crucial for blood clotting and bone health. Such a comprehensive array of benefits makes kale juice a highly versatile and effective supplement ingredient.

 

Forms of Consumption

The versatility of kale juice extends to its various forms of consumption, suitable for different supplement delivery methods:

 

  1. Liquid Extracts: Pure kale juice extracts can be used in liquid supplements.

 

  1. Capsules: Dried kale juice can be encapsulated for easy consumption.

 

  1. Powders: Freeze-dried kale juice powder is well-suited for drink mixes.

 

  1. Blends: Often included in multivitamin formulations or green superfood blends.

 

  1. Functional Foods: Kale juice can even be incorporated into functional foods like bars and shakes.

 

Safety + Dosages

Kale juice is generally considered safe for consumption. However, its high vitamin K content could interfere with blood thinners. Therefore, medical consultation is advised for those on such medication. 

As for dosage, it varies depending on the form and the specific supplement’s formulation. 

 

Use and Legality in UK, EU, US and Globally

In the UK and EU, kale juice supplements are classified as food supplements and are subject to general food safety regulations. The US has a similar approach, with the FDA considering kale and its juice as Generally Recognised As Safe (GRAS).
