The quality of PDRN supplements depends on DNA micronization methods(such as DOTâ¢) and purity (95% or higher))Be sure to check the manufacturing technology..
There are individually approved raw materials whose joint health and skin health functionalities have been officially recognized by the MFDS. You must be able to distinguish between regular foods and health functional foods..
Since nucleic acid components are metabolized to uric acid in the body, patients with gout or high uric acid levels must consult with a specialist before deciding whether to take it..

Two seemingly identical PDRNs, what's different?

Not long ago, a customer placed two PDRN products side by side on the pharmacy counter..

"Pharmacist, both of these say salmon DNA on the label, but the price is three times different. What's different??"

The ingredient names on the front were the same. The packaging looked similarly clean, and both were prominently displaying the word PDRN on the front. However, when I flipped over the back to check, everything was completely different..

In Part 1, we covered the identity of the ingredient PDRN, and in Part 2, the regeneration mechanism at the cellular level. If you haven't read it yet, [Salmon Component 97% Identical to Human DNA, After Collagen comes PDRN]you'll find it easier to understand if you first grasp the basic concepts. Now, in this final Part 3, I want to answer the most practical question: "Which product should I choose, and who shouldn't take it??"

Manufacturing Technology Determines PDRN Quality â DOTâ¢ Method and Purity

Extracting DNA from salmon milt is identical across all manufacturers. The difference occurs in the next step..

The extracted DNA originally has a very long chain structure. It's necessary to cut this long chain into a size that the human body can absorb and utilize, and this is where each manufacturer's technological capability becomes starkly apparent..

A representative technique is DOT™(DNA Optimizing Technology)This method micronizes DNA fragments extracted from salmon to approximately 1/670 of pore size. In simple terms, it's similar to dividing large cargo that can't fit through a door crack into parcel box sizes. Only with appropriate size can it reach the cells, and only when it reaches can the regeneration pathway explained in Part 2 work..

The key is not just making particles small, but processing them to the optimal size that maintains biological activity while being able to pass through cell membranes..

As important as micronization is purity When extracting DNA from salmon milt, impurities like protein or fat can come along. Such impurities can cause allergic reactions. It's important to confirm that the raw material has been purified to 95% or higher purity through a refining process..

Here are the criteria you can check when choosing a product:.

Item to Check	Standards for Quality Products	How to Verify
Micronization Method	Patented technology applied such as DOTâ¢	Product detail page, raw material supplier verification
DNA Purity	95% or higher	Test report (CoA), product labeling
Molecular Weight Range	50~1,500 KDa	Check raw material specifications
Raw Material Origin	Specified as derived from salmon milt (Milt)	Check ingredient list and raw material source

Even if a product displays the name PDRN on its surface, caution is needed if no information about micronization method or purity is disclosed..

Recently, research is also underway to extract PDRN (PhytoPDRN) from ginseng to reduce resistance to animal-derived ingredients. Using ultra-high pressure physical disruption methods to minimize DNA denaturation, there's potential for a wider range of raw material choices in the future..

Regular Food and Health Functional Food, Not the Same PDRN

PDRN products on the market are broadly divided into two categories: products classified as regular food and, health functional food certified products. This difference is bigger than you might think..

Health functional food is a product whose scientific evidence for specific functionality has been recognized by the Ministry of Food and Drug Safety (MFDS). In Korea, salmon milt extract has been approved as an individually approved raw material and the officially recognized functionalities are as follows:.

Joint Health

In 2019, the MFDS recognized the functionality that salmon milt extract (PRP salmon nucleic acid) "may help maintain joint health"In a human application trial conducted at Inje University Seoul Paik Hospital, when osteoarthritis patients consumed this raw material, significant improvements in pain index (VAS) and knee joint function index (K-WOMAC)were confirmed..

Skin Health

Salmon nasal cartilage extract (proteoglycan marker) was approved for "may help maintain skin health from skin damage caused by UV rays" and "may help with skin hydration".

The 12-week clinical trial results are backed up by specific numbers:.

Evaluation Indicator	Intake Group Results (vs. Control))
Skin Moisture	30% Increase
Eye Wrinkles	30% Reduction

These results were possible because nucleic acid-derived components promote ceramide synthesis that constitutes the skin barrier, and inhibit the activity of MMP-1 and MMP-9, enzymes that break down collagen..

There's one point I need to clarify here. The functionality recognized by the MFDS for what we commonly call PDRN, that is, the component extracted from salmon milt, is joint health In contrast, the functionality recognized for skin hydration and UV damage management is proteoglycan component extracted from salmon nasal cartilage. Although from the same salmon, the extraction site and marker component are different, and the recognized functions are different as well..

If skin care is the goal, the real pharmacist's tip is to verify whether the product combines milt-derived PDRN and proteoglycan components rather than a PDRN-only product..

Just because a product says PDRN doesn't mean it's been officially recognized by the MFDS for skin functionality. You must read the functionality content on the back accurately to see which raw material was approved for which functionality..

Be Sure to Check â Gout and Uric Acid, and Drug Interactions

This section is the most important part of this series..

Salmon milt extract, the raw material for PDRN, is a biologically highly concentrated purine (Purine)) source. As purine is metabolized in the body, it generates uric acid (Uric Acid))as its final product..

In healthy adults, uric acid is normally excreted through the kidneys. However, for those who already have elevated uric acid levels, the situation is different..

Gout and Hyperuricemia

Gout patientsor those diagnosed with hyperuricemia must consult with their attending physician or pharmacist before taking PDRN supplements.. When purine goes through an oxidation process and turns into uric acid, urate crystals can accumulate in the joints, potentially triggering a gout attack that causes severe pain..

According to Japanese gout guidelines,, daily purine intake should be limited to 400 mg or less High-dose salmon DNA supplements can account for a significant portion of this limit..

However, it's not dangerous for everyone. In studies on healthy adults with no abnormalities in purine metabolism, the effect of DNA intake on blood uric acid levels was limited to about half that of RNA intake in the same amount. If you have no family history of gout and your uric acid levels are normally within range, excessive worry is unnecessary..

Duplicate Intake with Niacin (Vitamin B3)

As a pharmacist, I want to point out one more thing here..

You might wonder what relationship niacin has with gout. Our kidneys have URAT1 a urate transporter. In simple terms, it acts like a gatekeeper pulling back into the body the uric acid that should escape through urine..

Niacin (vitamin B3))interacts with this URAT1 transporter and prevents uric acid from being excreted in the kidneys.. If niacin is added to a state where PDRN intake has increased purine, the raw material for uric acid, it becomes a situation where uric acid is produced faster while the pathway for it to escape narrows.. Blood uric acid levels can fluctuate significantly, so those on the borderline of gout risk need to be especially careful..

If you're separately taking a multivitamin or B-complex supplement, I recommend checking the niacin content in the nutrition label of that product..

Other Precautions

Those with fish roe allergies may experience itching or hives when taking PDRN.. While most protein is removed during the purification process, those with extremely sensitive constitutions may have reactions..

Pregnant and Nursing WomenCurrently lack sufficient direct safety data. Be sure to consult with a specialist before taking..

Those already taking urate-lowering agents or those with reduced kidney function must also consult with their healthcare provider before deciding whether to take it..

Even if ingredients look good, it's necessary to develop a habit of first checking whether they suit your body condition and whether there's any overlap with other products you're taking.. [Before Taking Glynak, Misconceptions a Pharmacist Must Clarify]is also helpful from the same perspective..

How to Choose PDRN by Formulation â Film, Gummy, Liquid

PDRN supplements have different absorption methods and uses depending on the formulation. Choosing a formulation that matches your lifestyle and purpose can improve intake efficiency..

Oral Dissolving Film (Direct Film))

This is the method of placing and dissolving it under the tongue or on the roof of the mouth. The biggest advantage is direct absorption into blood vessels through the oral mucosa without going through the digestive tract..

To use an analogy, it's like a package being delivered directly to your door without going through a logistics center. You can avoid destruction by stomach acid and minimize first-pass metabolism where components are filtered by the liver, which is advantageous for improving bioavailability..

Gummy/Jelly (Glow Jelly))

It's convenient to take and suitable for combining with other skin constituent components like collagen, elastin, and hyaluronic acid. While PDRN sends regeneration signals, the combined components can serve as the necessary material for actual reconstruction..

The fact that it has good taste and texture, making it easy to maintain consistent intake habits, is also an advantage that shouldn't be overlooked..

Liquid/Ampoule (Liquid Ampoule))

It has rapid absorption speed and is suitable for containing high-concentration PDRN. It's typically provided as a beverage to drink immediately after procedures at hospitals or is utilized as a high-functionality home care product..

Formulation	Absorption Characteristics	Suitable Users
Oral Dissolving Film	Direct oral mucosa absorption, minimal first-pass metabolism	Those who prioritize absorption efficiency
Gummy/Jelly	Via gastrointestinal tract, synergistic component combination possible	Those wanting complex intake with collagen and other components
Liquid/Ampoule	Rapid absorption speed, high concentration possible	Those whose goal is intensive care before or after procedures

Synergistic PDRN Combinations, a Pharmacist's Routine Suggestions!

While PDRN alone is a meaningful component, there are combinations that can create synergy when taken together..

Vitamin C is an essential cofactor for collagen synthesis. When PDRN wakes up fibroblasts and sends a signal to make collagen, vitamin C plays a role in substantially completing that synthesis process. Additionally, through antioxidant action, it protects newly created cells from oxidative stress..

Elastin and hyaluronic acid are key components for maintaining skin elasticity and hydration. While PDRN lays the foundation for regeneration, when these components supply structural material, the results can appear more complete.. If you want to choose collagen products together with a focus on skin elasticity,, [Oral Collagen, Which Product Should You Choose??]is also worth referring to..

As explained in Part 2, PDRN is the architect, and these components correspond to bricks and finishing materials. An architect can work alone, but if materials are prepared, the building is completed much faster..

In Closing

In Part 1, I shared the story of PDRN moving from hospital procedure rooms to home dinner tables. In Part 2, I explained the scientific principle of how this component turns on the regeneration switch at the cellular level. And in this final Part 3, I've summarized the criteria for choosing quality products and the precautions that must be observed..

PDRN is certainly a component with different potential than collagen in skin regeneration. However, no matter how good the component is, it's meaningless if you don't first examine your body condition..

Understanding the mechanism, confirming the quality, checking if it's right for you, and then making a choice. That is the true completion of true inner clinic..

If you have any questions, feel free to ask the pharmacist at your nearby pharmacy. That's why we're here..
