OPC Premium according to Dr. med. Michalzik
is made from French grapes.
Was ist echtes OPC? Dr. med. Alexander Michalzik und Dr. rer. nat. Klaus Denzel im Gespräch
Dr. rer. nat. Klaus Denzel erkärt die unterschiedlichen Messmethoden für den Gehalt an OPC (Oligomere Proanthocyanidine) bei Nahrungsergänzungsmitteln. Polyphenolgehalt ist nicht gleich OPC-Gehalt. Auch monomere oder polymere Proanthocyanidine sollten nicht zu den OPCs gerechnet werden.
You receive 720 mg OPC per euro, or 720,000 mcg OPC per euro (320,000 mcg per capsule). Compare this value. We do not count monomers as OPC. There are providers who write, "highest purity per capsule worldwide: 60,000 mcg". However, this is only 60 mg per capsule. "Native OPC premium according to Dr. med. Michalzik" is a tested OPC product. The verified high content of pure OPC in the grape seed extract gives the customer confidence that when it says OPC, it really is OPC.
"OPC 95 - The strongest antioxidant in the world. Perhaps the best OPC in the world" is an advertising slogan used by competitors. They further claim: "Unbeatable price-performance ratio". Let’s take a closer look: The provider refers to OPC 95. This designation is also used by raw material suppliers who promise 95% OPC but, when asked, do not test the OPC content—usually only the polyphenols. This is a major difference! Likewise, for example, "105 mg OPC per capsule" is declared. With 95% OPC, this would be 110.5 mg grape seed extract per capsule. However, the OPC content is not proven by an analysis. With a similar provider from Switzerland, despite a claim of 300 mg OPC, we were only able to find 5 mg in the analysis. It is not stated where the grapes come from. Often, grape seeds grown in China are used. Prices are then extremely low. By comparison: Biotikon has 450 mg grape seed extract per capsule, i.e. four times as much. The OPC content of 320 mg is based on analyses; the analysis is published. The grape seeds come from France.
Conclusion: On closer inspection, it is not always the cheap product that has a better price-performance ratio.
OPC 300 mg: This advertising promise is made by competitors with only 300 mg grape seed extract content. The OPC content would then have to be 100%. Here, grape seed extract is equated with OPC content.
OPC 95%: The designation OPC 95 is used by many manufacturers to describe their OPC quality, but as a rule it indicates a lower OPC quality. Here, it usually does not mean the OPC content, but the analysis value according to "Bate Smith", which provides ratio values and is not suitable for measuring OPC precisely. Or it means the polyphenol content. This means that OPC 95% does not mean that 95% OPC is contained. If you buy OPC, ask for the original certificate of analysis from a German independent analysis institute that shows the OPC content.
OPC 400 mg, 450 mg, 500 mg: Here too, you should ensure that this is not the capsule weight, but how high the actual OPC content is.
OPC analysis, OPC verification
OPC is a substance that is recognized worldwide, but few master the difficult topic of OPC analysis. The OPC certificate of analysis should always state OPC. What matters is the OPC content verified by grape seed extract analyses. Have the OPC content confirmed by a German certificate of analysis from a German laboratory. The location of the OPC provider in Germany is also important, as in some other countries no verifications are required.
OPC according to Dr. med. Michaltik also contains Vitamin C. This contributes to:
- normal collagen formation for the normal function of cartilage, bones, blood vessels, gums, teeth and skin
- normal function of the nervous system and the psyche
- protecting cells from oxidative stress
- the reduction of tiredness and fatigue
- normal energy-yielding metabolism
- normal function of the immune system
Synonyms:
Abbrev.: OPC or PCO
German: Oligomeric proanthocyanidins,
procyanidins, vitamin P, flavonoids
English: Oligomeric proanthocyanidins
Quality features
of OPC premium Dr. med. Michalzik
- 320 mg OPC in the special grape seed extract Dr. med. Michalzik, measured using the RP-HPLC method (test procedure PV.03.P194_02). OPCs are proanthocyanidins. Monomeric proanthocyanidins are not counted towards the OPC capsule content. The test procedure can be viewed at www.opc-traubenkernextrakt.de.
- 450 mg special grape seed extract per capsule
ORAC value
ORAC units of the current batch more than 14,000 micromol TE per capsule (hydrophilic and lipophilic). The ORAC method is a reliable measurement method for the ORAC value (ORAC is an abbreviation for Oxygen Radical Absorbance Capacity) and indicates the ability of a substance to bind radicals. ORAC OPC analysis: more than 6000 ORAC units per capsule. The total ORAC value (value measured lipophilic and hydrophilic) was stated by the renowned "Labor Prof. Kurz" for the current grape seed extract batch as 32,092.6 micromol TE per gram. Native OPC premium is made from French grape seeds. Total OPC ORAC value (click here to view ORAC OPC analysis) According to the current state of knowledge, there is no sufficiently scientifically substantiated evidence regarding the ORAC value as to what influence it has on physiological processes in the human body and on maintaining its health. However, the ORAC value is an important characteristic of the grape seed extract used, i.e. the raw material for capsule production. If grape seed extracts are exposed to air and higher temperatures for a long time, the ORAC value decreases because the OPC can already partially oxidize.French grape seeds 380 mg total polyphenols per capsule from 450 mg grape seed extract Processing and product control in Germany Absolutely no additives in the capsule fillNo magnesium stearate, this metal soap originally comes from the construction industry and is used by many manufacturers. Certified goods with a German OPC certificate of analysis for your safety. RP-HPLC OPC analysis method for reliable OPC ingredient information. The RP-HPLC method, reverse phase high-performance liquid chromatography, is a very valid OPC analysis method. OPC is the abbreviation for oligomeric procyanidins. OPC Premium Dr. med. Michalzik does not add monomeric procyanidins to the analysis result.
Checklist for buying OPC
What you should pay attention to when purchasing OPC products:
Grape seed extract is not the same as OPC. You must ensure that the manufacturer differentiates between them. Procyanidins can also be present in monomeric form, but these are not OPC. The OPC information should be supported by a German certificate of analysis. Processing in Germany. The grape seeds should ideally come from Western Europe. Our grape seeds come from France. Avoidance of additives in the capsule fill. Short delivery time, thus maintaining quality. OPC capsule material from plant-based raw material (cellulose). Use of suitable analysis methods.
Below you can view various sample analyses of the grape seed extracts we use for our OPC products. We are also happy to send these to you by post. The values measured with the RP-HPLC method are the basis for evaluating the OPC content of our current extract. We carried out the vanillin method, butanol method (procyanidin assay), Porter-Bate-Smith on earlier grape seed batches to obtain further information, but they are not the basis for our OPC specification.

The values from Porter Bate-Smith and DMAC are from our raw material from the last batch. The raw material batch currently used in the OPC products was tested by RP-HPLC. OPC_Porter_Bate-Smith (click here to view OPC analysis according to Porter-Bate-Smith)
The values from Porter Bate-Smith, pharmacopoeia method, vanillin and procyanidin assay (butanol method) are from our raw material from the last batch. The raw material batch currently used in the OPC products was tested by RP-HPLC and DMAC (see above) Certificate of analysis according to the vanillin method, procyanidin assay (butanol method) and the pharmacopoeia method (EP6.0 1220) (click here)
