Hello, this is Eojungi from Yagal..

If you've visited the Yagal website, you've probably seen that various products have scores and recommended items listed..

Did you know that at Yagal, staff members evaluate products for each ingredient??

It may look simple on the surface, but we search for relevant research papers,,

find company websites in English,,

and go through textbooksâit's a process that requires an enormous amount of time. ã ã

Since everyone at Yagal works this hard on product evaluations, I hope all of you who visit Yagal will trust us and make your choices with confidence.!

Today, I want to explain the standards that I, as the person in charge of Vitamin A and Lutein,

use to score products..

After reading this column, you'll also develop the ability to distinguish between good products and poor products on your own..

1. Active Ingredients

There are three major factors we look at for active ingredients..

Is the dosage appropriate??
Is the ingredient quality good??
Were natural substances used??

First, regarding dosage, we deduct points if the amount falls short of the daily recommended intake or exceeds it..
This is because vitamin A has severe side effects when overdosed..
We score ingredients in this order: beta-carotene > palmitate > acetate..
We give higher scores for combination ingredients.
Finally, for natural substances, we give the highest score to pure natural substances,
give differential scores based on ratios for combination ingredients,
and give the lowest score if there are no natural substances..

You can verify all of these items by going to the product description..

If it's not shown in the product description, you can check the company's website for that product..

However, for foreign companies, the information is in English, so it may be difficult for you to find....

2. Inactive Ingredients

Actually, for vitamin A, we didn't place much weight on inactive ingredients in our evaluations..

This is because there are many single-ingredient products, and there are relatively few research papers on inactive ingredients that significantly enhance effectiveness..

So we give bonus points to products containing eye-related ingredients like bilberry

and products that include other vitamins together..

3. Brand

Brand is a factor I haven't covered in my other columns,,

because it's unrelated to the active ingredient itself..

Each company has various certifications for their production processes and the materials used..

One example is GMP..

GMP is an abbreviation for good manufacturing practice,.

and it's a certification that a company has undergone inspection of its production process and maintains an appropriate manufacturing process..

Besides that, there are vegan certifications like kosher and halal, gluten-free certifications, and raw material supplier certifications, and many other types of certifications..

Obtaining each of these certifications requires money, time, and effort from the company's perspective,

so we give higher scores to companies that hold these certifications..

However, we don't give high quality scores just because a company is working hard.!

In fact, having received such certifications means that multiple organizations have inspected the product and found it to be

trustworthy in quality..

For Korean products, certifications are usually displayed on the product,,

but for foreign products, certifications are often not displayed, and you have to visit the company website to verify them..

That's why I always visit each product's company website to verify before giving it a brand score..

For this reason, the brand section is the part that takes the longest time in product evaluation..

4. Quality

For quality, we focus on storage, convenience of use, and absorption rate..

Individually packaged products do not deteriorate compared to products packaged all at once and
can be stored longer, so we give them higher scores..
Next, regarding absorption rateâdo you remember that when it's a lipid-soluble capsule, it's absorbed well by the body??
We give the highest score if the formulation is a lipid-soluble capsule,,
and we give differential scores even among lipid-soluble capsules depending on the capsule's solvent..
Finally, convenience of useâ,
the fewer times you need to take it per day, the less attention you need to pay, so we give higher scores for fewer daily doses..
Also, if capsules are too large, they're difficult to swallow, so we deduct points for formulations that are too large..

In this column, I've explained how product evaluations are conducted,.

and I hope you understand the effort we put into scoring.!

So I hope you all take care of your health through Yagal,

and this has been Eojungi from Yagal..
