Black Tea Shows Heart Health Benefits

Black Tea Shows Heart Health Benefits

Black Tea Shows Heart Health BenefitsAlthough the consumption of tea goes back to ancient days and is a practice well-known to the eastern world, consumer interest in the consumption of tea in the United States has just recently caught on. Innovative marketing, together with recent discoveries from scientific research affirming the brew's health and relaxation benefits, are driving its explosive popularity across the nation.

Endless varieties of teas come from all over the world but the main constituent, known to impart antioxidant benefits, called polyphenols, are found in varying degrees in all types of teas. Green tea contains the highest concentration (about 30 to 40 percent) of water-extractable polyphenols. Because black tea is oxidized through fermentation, many of its polyphenols are lost reducing its polyphenol content to about 3 to 10 percent. In spite of this, recent research shows that 3 cups a day may hold specific black tea health benefits to support a healthy heart. 1

Is Black Tea Good For Your Heart?

Several epidemiological studies and clinical trials over the years have studied the benefits of black tea and its effect on cardiovascular health. Studies that have followed people over a long period of time suggest that consumers who regularly drink black tea may experience improved cardiovascular health. 2

More recently, a team of scientists from Mauritius, Scotland and the United States associated the consumption of 9 grams of black tea with improvements in various cardiovascular health markers. Scientists attributed these results to the synergistic effects of the tea polyphenols and other antioxidant elements. Although the mechanism of this phenomenon needs to be studied further, black tea health benefits may provide consumers with a daily antioxidant defense to help support cardiovascular disease. The clinical trial consisted of 87 people aged between 25 and 60. For 12 weeks, these participants randomly received 200 ml of black tea a day or an equal quantity of hot water to drink. 3

What are the Health Benefits of Black Tea?

Derived from the Camellia sinesis plant, black tea is also known to increase mental alertness, and may improve learning, memory and information processing skills, according to the National Institutes of Health. Black tea is also used to support healthy blood pressure and support healthy weight loss management. 4

Other health benefits of black tea may include:

  • Lower LDL cholesterol
  • Improve gut health
  • Reduce the risk of stroke
  • May lower blood sugar levels
  • Lower the risk of kidney stones

Manufacturing Tea Supplements

According to the Tea Association, tea sales in the United States surged from $1.8 billion in 1990 to $7.7 billion in 2010. The industry expects continuous growth in the next 5 years "driven by convenience, interest in the healthy properties of tea, and by the continued discovery of Specialty Tea." 5 You can easily provide your customers with the health benefits of black tea by formulating your own line of high-quality capsules with NutraScience Labs.
