The Abell-Kendall method, which involves ultracentrifugation for lipoprotein fractionation, is a highly accurate and precise laboratory technique. However, comparing its accuracy directly to other methods such as enzymatic, electrochemical, or colorimetric methods is not straightforward because each method has its own strengths and limitations.

Abell-Kendall Method:
  • Strengths: Provides detailed information on lipoprotein fractions and is considered a reference method in research settings.
  • Limitations: Labor-intensive, time-consuming, and requires specialized equipment. Not practical for routine clinical testing or home use.

Enzymatic Methods:
  • Strengths: Generally accurate and widely used in clinical laboratories. Can be automated for high-throughput testing.
  • Limitations: May be affected by interfering substances. Results can be affected by variations in reagents and methodology.

Electrochemical Sensors:
  • Strengths: Quick results, suitable for point-of-care testing. Portable and user-friendly.
  • Limitations: May be less accurate compared to laboratory methods. Results can be influenced by factors such as hematocrit levels.

Colorimetric Methods:
  • Strengths: Simple, cost-effective, and suitable for various settings, including home use.
  • Limitations: May be less accurate compared to more sophisticated laboratory methods. Results can be affected by external factors.

While the Abell-Kendall method is considered a reference standard for lipoprotein fractionation, its complexity limits its use in routine clinical settings and home testing.

For routine cholesterol testing, enzymatic methods are commonly used in clinical laboratories due to their balance of accuracy, efficiency, and automation. Home cholesterol testing often relies on simpler methods like enzymatic or colorimetric assays due to their ease of use.

It's important to note that accuracy can also depend on factors such as the quality of reagents, calibration, and adherence to standardized procedures.

-Is titanium dioxide also being banned in non-food products?
-Will still be authorised for use in medicinal products until other safe alternatives are found. This is to avoid causing shortages of medicinal products that could negatively impact public health or animal health and welfare.

In January 2022, a regulation was issued to withdraw the authorization for the use of titanium dioxide as a food additive in food, aka EU Commission Regulation 2022/63.

This regulation entered into force on February 7, 2022. However, the regulation included a six-month transition period to give food businesses time to phase out the use of this food additive and reformulate the recipes in their products using suitable alternatives. This period ended on August 7, 2022.

Foods before 7 August 2022 can remain on the market until the written, end date of consumption. Food produced or placed on the market after 7 August 2022 cannot contain titanium dioxide. source

(2024) Japan: Fifth suspicious death in dietary supplement scandal Monacolin K (Greek)

Monascus purpureus also known as red yeast rice has been traditionally used in China for hundreds of years as a spice added to foods. Only in the 20th century it was discovered that the Chinese did not suffer from high cholesterol due to the consumption of this spice. Monascus purpureus contains a natural substance called Monacolin K. In September 2011, European Food Safety Authority (EFSA) approved a health claim for Monacolin K extracted from Monascus purpureus as a natural cholesterol management dietary supplement in a concentration of 10 mg per dose. reference (2011) EFSA Journal 2011;9(7):2304

Red yeast rice, monacolin K (aka lovastatin), was the first statin commercialised by pharmaceutical companies. Therefore, monacolin K may be considered a drug in several European countries. Despite the fact that red yeast rice is a borderline ingredient between food supplements and drugs, the European Food Safety Authority has recognised the cholesterol-lowering properties of monacolin K in the evaluation of two health claims, and the European Commission has validated a health claim related to monacolin K and the maintenance of normal blood LDL-cholesterol concentration in Regulation (EC) No. 432/2012. source (2015)

Monacolin K is a naturally occurring compound found in red yeast rice, specifically from the fermentation of Monascus purpureus. It has been found to have a chemical structure similar to the prescription statin drug lovastatin. Lovastatin and other statins are commonly prescribed to lower cholesterol levels. While monacolin K can be effective in lowering cholesterol, it's important to note that it essentially functions as a natural statin and may carry some of the same risks and side effects as synthetic statin medications.

(CA) Cholestatin - Romanian distro (20e) | same domestic Romanian language only (13e) --- 10mg of Monacolin K
(PL) Cholesten
(GR) Drugs with lovastatin
(IT) Zeta Colest - Φυσικά Συστατικά στη Ρύθμιση των Λιπιδίων (Red Yeast Rice + Berberis) --- 2.9mg of Monacolin K

In particular, its effectiveness is directly related to the amount of monacolin K within the extract (up to 10 mg/day). Consuming monacolin K on a daily basis reduces low-density lipoprotein (LDL) cholesterol plasma levels between 15% and 25% within 6 to 8 weeks. source

Monacolin K and lovastatin are closely related compounds, and in fact, monacolin K is the naturally occurring form of lovastatin. Both substances have similar chemical structures and mechanisms of action. Here are the key differences and similarities between monacolin K and lovastatin:

Source:
Monacolin K: This compound is naturally found in red yeast rice (Monascus purpureus) as a result of the fermentation process.​
Lovastatin: It is a synthetic statin drug that was originally derived from the fermentation of a different fungus, Aspergillus terreus. Lovastatin is then processed and manufactured as a prescription medication.​

Chemical Structure:
Monacolin K: It is a naturally occurring compound that is structurally identical to lovastatin.​
Lovastatin: This is the synthetic form of monacolin K. The chemical structures of the two compounds are essentially the same.​

Medical Use:
Monacolin K: Found in red yeast rice and used as a dietary supplement for its potential cholesterol-lowering effects.​
Lovastatin: Prescribed as a medication to lower cholesterol levels and reduce the risk of cardiovascular events.​

Regulation:
Monacolin K: Often marketed as a dietary supplement, which is regulated differently from prescription medications.​
Lovastatin: Available only as a prescription medication, subject to stricter regulatory oversight.​

Dosage Control:
Monacolin K: The content of monacolin K in red yeast rice supplements can vary, and the potency may not be standardized.​
Lovastatin: Pharmaceutical formulations allow for precise dosage control, ensuring consistency in the amount of the active ingredient.​

Safety and Side Effects:
Both monacolin K and lovastatin may have similar side effects, including muscle pain, liver enzyme abnormalities, and gastrointestinal issues.​
Lovastatin, being a regulated prescription medication, has undergone extensive clinical testing, and its safety profile is well-documented.​

Overall lovastatin got a pharma copyright and is ready to be sold as drug.

Statins can affect the production of other substances in the body, including CoQ10. CoQ10 is important for the functioning of mitochondria, which are the energy-producing units in cells, and it is particularly vital for the heart, which has high energy demands. The degree of CoQ10 depletion with red yeast rice (aka monacolin K) supplements may be less than that observed with some synthetic statins.

Statins primarily affect the production of cholesterol in the body. They work by inhibiting an enzyme called HMG-CoA reductase, which is involved in the synthesis of cholesterol in the liver.

other substances affected apart CoQ10
  • Dolichols: Statins may affect the production of dolichols, which are involved in the glycoprotein synthesis and modification processes.
  • Isoprenoids: Statins can influence the levels of isoprenoids, potentially affecting the activity of certain proteins.

Laboratories use various methods to analyze the fat, carbohydrates, and protein content of food ingredients. These methods involve separating and quantifying the different components of a food sample. Here's a brief overview of the techniques commonly used for each nutrient:

  1. Fat analysis:
    • Gravimetric Method: Involves extracting fat from the sample using a solvent, then weighing the extracted fat.
    • Titration: Uses a chemical reaction to determine the amount of fat present.
    • Spectrophotometry: Measures absorbance of light by fat in the sample.
  2. Carbohydrate analysis:
    • Total Carbohydrate Analysis: Measures all carbohydrates, including sugars, starches, and dietary fiber.
    • Enzymatic Methods: Use specific enzymes to break down carbohydrates into simpler components for analysis.
    • High-Performance Liquid Chromatography (HPLC): Separates and quantifies individual carbohydrates in a sample.
  3. Protein analysis:
    • Kjeldahl Method: Involves digesting the sample with concentrated sulfuric acid, converting nitrogen to ammonium sulfate, and then quantifying the nitrogen content, which is used to calculate protein.
    • Dumas Method: Similar to the Kjeldahl method but uses combustion to convert nitrogen to nitrogen gas.
    • Biuret Method: Utilizes a color reaction between proteins and copper ions.
  4. Other techniques:
    • Near-Infrared Spectroscopy (NIRS): Measures the absorption of infrared light to estimate the content of various nutrients, including fat, carbohydrates, and protein.
    • Gas Chromatography (GC): Separates and quantifies volatile compounds, including some fatty acids.

Voltaren Emugel or Voltarol Emugel ?

Both have as active ingredient the Diclofenac sodium.

Works be decreasing the production of prostaglandins which is a hormone produced when we have pain or inflammation. Body produces it, in response to injury or illness. Is are part of the inflammatory response, which is the body natural mechanism for healing. Excessive inflammation can cause pain and discomfort. By reducing the production of prostaglandins, diclofenac sodium helps alleviate pain and reduce inflammation without completely eliminating the body ability to heal.



Diclofenac was first synthesized by Alfred Sallmann and Rudolf Pfister and introduced as Voltaren by Ciba-Geigy (now Novartis) in 1973.

Later on 2015 GlaxoSmithKline (aka GSK) purchased the rights to sell it as well under the name Voltarol. source

May you see GSK (aka GlaxoSmithKline) on Voltaren package this is due GSK reaches agreement with Novartis to acquire full ownership of Consumer Healthcare Business.

Voltarol has a strength of 1.16%, whereas Voltaren has a strength of 2.26%.
