Recently while researching the anti-viral properties of green tea I came across this 2021 review study.
This surprised me because it showed that Theaflavins from Black tea can be just as, and in some situations more protective against viral infections than EGCG from Green Tea.
In addition to studies showing that black tea theaflavins lower cholesterol, (both LDL and total), lower triglycerides, and are also protective against atherosclerosis, high blood pressure, and metabolic syndrome, additionally there is ample evidence showing that Green tea is also highly cardioprotective and lowers LDL-cholesterol. 
Opti-CardioClear contains both black tea theaflavins and green tea catechins along with a citrus extract called Sytrinol. In a previous article, I explained that
"Sytrinol has been shown in human trials over a period of 4 to 12 weeks to lower triglycerides levels by as much as 34%, total cholesterol by up to 30%, and LDL cholesterol up to 27%. [8,9,10]"
So together, the ingredients in Opti-CardioClear are a powerhouse for controlling blood fats and cholesterol. (In this regard I have seen excellent results combining it with L-Carnitine).
For more information on the cardiovascular benefits of CardioClear see the article below.

CardioClear: Ancient Support For a Modern Epidemic
Cardiovascular diseases are still the most common cause of death in the world, and further preventive wellness strategies for cardiovascular health are needed. In this regard, addressing a cluster of symptoms termed "metabolic syndrome" is key.
As evidenced below, metabolic syndrome is a precursor to diabetes, which results in increased risk of heart disease, arterial disease, and stroke. Signs include high fasting insulin levels, increased blood sugar, elevated blood fats cholesterol and triglycerides, high blood pressure (hypertension), fat accumulation around the waist, and increased levels of inflammation.
A group of food constituents called polyphenols, such as those in black tea, i.e. "theaflavins" and “catechins", as well as citrus extracts have been shown to positively impact virtually all aspects of metabolic syndrome and cardiovascular health.
As summarized in a 2015 study on the ability of black tea constituents to protect arterial linings and reduce homocysteine-induced hypertension in rat aortae:
"Compelling evidence in human and murine models also suggest various cardio-protective benefits of consuming tea or tea polyphenols under pathological conditions, including hypertension, atherosclerosis, diabetics, hypercholesterolemia, and obesity; and are attributed to antioxidative, anti-thrombogenic, anti-inflammatory, hypotensive and hypocholesterolemic properties of tea polyphenols 7,8,9,10"
As indicated above, Black tea theaflavins:
- Are protective against hypertension and have blood pressure-lowering properties   
- Are highly anti-inflammatory and antioxidant  
- Reduce cholesterol, (both total and LDL), blood sugar, and triglycerides, and exert antidiabetic effects    
- Reduce the risk of atherosclerosis (hardening/calcification of the arteries) 
- Reduce the risk of stroke 
- Reduce the risk of metabolic syndrome, cancer and cardiovascular disease in general  
And though their mechanisms of action may be different, green tea catechins share many of the same benefits.    
So the obvious question then is why not just drink tea?
Besides the fact that the content of the beneficial polyphenols can vary greatly, depending on the specific tea, the amount of tea you would have to drink is a lot... 4 to 16 cups per day (depending on the benefit you are seeking). Some may find this over-stimulating, not to mention a lot of liquid! 
Yet, if you are going to drink this much tea, make sure it is organic!
Non-organic tea, and the teabags it may come in, can be loaded with toxins such as pesticides, artificial ingredients, genetically modified organisms, polyethylene teraphthalate, polylactic acid... a biodegradable plastic, and many others.  (A very eye-opening expose on this topic is an article by Marc S. Micozzi, M.D., Ph.D, called "The sinister secrets swirling inside your teapot". ) Unfortunately, the business of tea has taken a once healthy food, and turned it toxic.
Yet, tea is certainly not the only beneficial source of polyphenols for cardiovascular health. They are commonly found in fruits and vegetables, and as I wrote in a former article on the subject:
“This synergy between Black and Green teas can be further enhanced with a third type of polyphenol, i.e. flavonoids from citrus extracts. More specifically, with standardized extracts of what are called polymethoxylated flavones, or PMFs. Not only have extracts of PMFs been shown to have positive effects on metabolic syndrome, a patented citrus and tocotrienol extract called Sytrinol has been shown in a human trials over a period of 4 to 12 weeks to lower triglycerides levels by as much as 34%, total cholesterol by up to 30%, and LDL cholesterol up to 27%. [8,9,10]"
As mentioned, the PMFs in Sytrinol® are combined with tocotrienols...highly antioxidant members of the vitamin E family, which studies show possess many of the same cardiovascular and anticancer benefits as tea polyphenols, and are also protective of the arterial lining, damage to which can be the first event in the formation of arterial plaques.  
Can we make things easier?
So as to provide all of these ingredients and their benefits in a convenient capsule form, Optimum Health Vitamins offers Opti-Elite CardioClear, which combines standardized amounts of theaflavins, catechins, citrus flavones, and tocotrienols.
At 47 mg of theaflavins per capsule, Opti-Elite CardioClear provides a tea equivalent of between 2-4 cups per capsule, with a suggested daily dose of 2-4 capsules. Definitely easier than drinking upwards of 16 cups of tea a day! (Caffeine content is approximately 6mg per capsule.)
And if you are looking to further enhance the metabolic benefits of Opti-Elite CardioClear, we have always recommended L-Carnitine as a companion product, because of its necessity for helping your cells' mitochondria to burn fat, and to help clear it in a completely healthy way from your bloodstream...while increasing your energy as well.
In conclusion, the benefits of polyphenols are far reaching, and may even extend to improving the status of your friendly gut bacterial populations. Once more at Optimum Health, what we have tried to accomplish in developing Opti-Elite CardioClear is to deliver as many benefits as we can in one capsule, and deliver them in a form that people will actually use, versus saying "Oh I'll just drink tea"...and then not doing it.

With regard to CardioClear, we suggest consulting a healthcare practitioner prior to use if you are pregnant or breastfeeding.
Can this be taken if I’m breastfeeding?
