+++BIOLOGIST: Just realize that not only the cinnamon, but tocotrienols, aged garlic, oregano, rosemary, ginger, turmeric, curcumin, capsaicin, mustard, black pepper (and others) vary in metabolic degree as weak HMG-CoA reductase inhibitors and therefore possess lipidemic action.
However instead of like statins primarily *blocking* cholesterol synthesis and liver enzymes, these compounds mostly degrade or downregulate. This down/regulation is an important distinction, I believe. This is what makes high-dose statins so harmful, and these other compounds, not so much.
For instance, tocotrienols as the analogs to vitamin E increase farnesol along the mevalonate pathway, which then downregulates HMG-CoA. Tocotrienols are found most abundantly in many foods as essential oils of palm, barley, rye, rice and oat.
Obviously red rice yeast is nature's most powerful HMG-CoA reductase inhibitor, containing over nine such compounds. Perhaps tocotrienols would need to be standardized to farnesol to make the common dosage as dangerous as statins? I'm unsure of the answer. For instance, it takes over 2.4 grams of red yeast to manufacture just 8mg of lovastatin. Those active 3mg of mevinic acids are gives lovastatin the drug its powerful HMG-CoA reductase ability.
As you've already stated, natural foods such as cinnamon are added to livestock feed for their anti-microbial properties, which also includes corn, oregano, thyme, and cloves. Wouldn't you much rather see these natural alternatives being used in healthy livestock than indiscriminate antibiotics? Certainly an overabundance of microflora found in the animals' intestine would reduce nutrition. Especially in the presence of polysaccharides this could increase harmful bacteria and other pathogens. While cinnamon added to foods also acts as a strong preservative, the active anti-microbial component being cinnamaldehyde.
Ok. You want the second most dangerous compound threatening the mevalonate pathway? That would be bisphosphonates such as Fosamax, used most commonly to treat osteoporosis. These have been demonstrated to cause osteonecrosis, or bone death due to a loss of blood; and just recently, bisphosphonates have been found to cause an increase in heart valve damage and arterial fibrillation.
+++BRIAN: I know a little bit about berberine. It's derived from the barberry plant, and is a very powerful, safe, and effective anti-inflammatory in both the COX-2 and LOX-5 inhibitor class -- second only to the ursolic acid, as found most prevelently in the herb holy basil. I vaguely remember reading about it being used to lower blood sugar. Is this why you're asking about it?
+++VIPERGG22: There's a point of diminishing returns to cinnamon, likely anything above 250-500mg daily. Yes, I had written on this forum about the *slight* dangers of supplementing with household cinnamon. Whole cinnamon could potentially contain trace amounts of oil-based toxins and other volatile chemicals. You therefore have two options if there's any genuine concern a) purchase water-soluable cinnamon extracts, such as CinnulinPF or b) immerse cinnamon in boiling water and spoon off the excess lipids, let it dry and use.
It's probably most safe and effective for lipid and blood sugar control to supplement with 500mg every other day... at least this is my opinion.
