[Yakal's 3-Line Summary💊]

Comprehensive vitaminsrefer to products containing A, B, C, D, and E all together, and, multivitaminsare products containing two or more types..
Water-soluble vitamins (B, C))don't remain in the body, so they have low toxicity risk, and, fat-soluble vitamins (A, D, E, K))accumulate in the body, so you must adhere to upper limit intake amounts.!
'Rather than which vitamin is better, the key is to consume vitamins in appropriate amounts that match your eating habits and health status..

Hello. I'm YAYA â½, the pillar of Yakals and the very essence of comprehensive vitamins.!

When you wake up in the morning, drink a glass of water, and habitually pull out your supplement bottle,.

'thinking 'this one should do everything'âyou grab a comprehensive vitamin..

But when you look at the ingredient list on the back, it's packed with letters and numbers.. Vitamin A? D? Why are there so many types of B? 😅

Today, I'm here to help relieve some of that complexity..

So your precious time isn't wasted, I'll go through the essentials carefully for you..

1. Comprehensive Vitamins vs MultivitaminsâWhat's the Difference??

Often, people use the terms 'comprehensive vitamins' and 'multivitamins' interchangeably. But are they really the same??

To give you the answer right away, there is a difference..

Comprehensive vitamins: contain all of vitamins A, B, C, D, and Ein a single product.
Multivitamins: contain two or more types of vitamins in a single product.

That said, comprehensive vitamins aren't necessarily always better..

Let me give you an example..

If you're only lacking vitamin D in your normal diet, it might be more efficient to choose a multivitamin with added vitamin D or a single-ingredient product rather than a comprehensive vitamin with all vitamins..

Conversely, if you need to supplement various nutrients due to overall dietary imbalance, comprehensive vitamins would be a good choice..

The key is to 'identify what nutrientsyou' need..

2. Two Properties of Vitamins: Water-Soluble vs Fat-Soluble

Vitamins are broadly divided into two types..

Water-soluble vitamins (B, C) are soluble in water..

Just like sugar dissolving in water,, they don't stay in the body and are excreted through urine.. So compared to fat-soluble vitamins, the toxicity risk from excessive intake is lower..

However,, if you take high doses for extended periods, side effects like indigestion or kidney stones can occur, so caution is needed..

Fat-soluble vitamins (A, D, E, K) are soluble in oil..

Because they easily accumulate in the body, you don't need to eat them every single day. Instead, you need to be careful about excessive intake. .

If you consume too much, these problems can occur:.

Vitamin A: fatigue, headache, loss of appetite
Vitamin D: kidney stones, vomiting, constipation
Vitamin E: increased bleeding risk, muscle weakness
Vitamin K: blood coagulation disorder

3. Understanding Each Vitamin in Detail

1) Vitamin A â The Guardian of Eye Health

Vitamin A plays various roles including eye health, immune function, skin health, and antioxidant action..

Vitamin A exists in two forms..

Retinoids: 'finished' vitamin A found in animal-based foods (eggs, milk) '
Carotenoids: 'raw materials' found in plant-based foods (carrots, spinach) that are converted in the body to vitamin A. '.

To put it simply,, when you eat vegetables like carrots, our body converts them into vitamin A and uses it..

Carotenoids are not 100% converted; only some become vitamin A..

According to research, when consuming 6mg of beta-carotene, it converts at approximately a 3.8:1 ratio, but at high doses of 126mg, the conversion rate drops to 55:1..

The recommended intake amounts are as follows:.

Men: 700-800 mcg / Women: 600-650 mcg
Upper Limit Intake: 3,000 mcg
(*mcg is another way to express micrograms, Âµg â meaning 1/1000 of 1mg.!)

Since carotenoids are converted in the body only as much as needed,, the risk of toxicity from excessive retinoid intake is lower..

2) Vitamin B â The Body's Charger

Vitamin B is a group consisting of 8 different types..

What they have in common is they play an essential role in converting carbohydrates, proteins, and fats into energy.!

This is why vitamin B is commonly called ''vitality vitamin.''.

Type	Main Role	Recommended Intake	If Deficient?
B1 (Thiamine))	Carbohydrate metabolism, nervous function	1.2mg / 1.1mg	Beriberi, fatigue
B2 (Riboflavin))	Energy metabolism, skin/eye health	1.5mg / 1.2mg	Angular cheilitis, dermatitis
B3 (Niacin))	Energy metabolism, cholesterol regulation	16mg NE (*see unit explanation below))	Dermatitis, diarrhea
B5 (Pantothenic Acid))	Energy metabolism	5mg	Fatigue, indigestion
B6 (Pyridoxine))	Protein metabolism, neurotransmission	1.5mg / 1.4mg	Anemia, numbness in hands and feet
B7 (Biotin))	Hair and skin health	30µg	Hair loss, dermatitis
B9 (Folate))	DNA synthesis, cell division	400µg	Anemia
B12 (Cobalamin))	Red blood cell production, nervous function	2.4µg	Anemia, neurological symptoms

(*''NE' stands for niacin equivalent.. Just like "100,000 won in cash + 50,000 won worth of convenience store gift certificates" is called "equivalent to 150,000 won total," niacin and nutrients it converts into are counted together.!)

Since vitamin B is water-soluble, excess amounts are excreted through urine..

That's why many comprehensive vitamin products contain high doses far exceeding the recommended amount..

If you want to focus on vitamin B complex, consider single-ingredient vitamin supplements or high-dose B complex products.!

3) Vitamin C â Your Body's Defense Shield

Vitamin C, the most famous water-soluble vitamin, !

is well known for protecting cells from free radicals through powerful antioxidant action..

In addition, it performs these other roles:.

Collagen synthesis: essential for skin elasticity, gum health, and cartilage and bone formation
Iron absorption promotion: helps absorb iron from plant-based foods and prevents anemia
Immune function enhancement: improves white blood cell function and participates in antibody production
Fatigue recovery: contributes in part to stress hormone regulation

The recommended intake is 100mg, and the upper limit intake is 2,000mg..

Since it's water-soluble,even if you consume more than the recommended amount, excess amounts are excreted through urine, the toxicity risk is low. However,,

if you continuously consume high doses (2,000mg or more), diarrhea, abdominal pain, and nausea can occur, and the risk of kidney stones may increase, so caution is necessary.!

4) Vitamin D â The Sunshine Vitamin

Vitamin D, which is synthesized when skin is exposed to sunlight,

'has the nickname 'sunshine vitamin.'' 😉

Its main roles are as follows:!

Bone health: helps calcium and phosphorus absorption to strengthen bones
Immune function regulation: helps increase resistance to infection
Cancer prevention: some research suggests the possibility of preventing certain cancers

And vitamin D has two types.!

Vitamin D2 (Ergocalciferol)): found in plant-based foods like mushrooms
Vitamin D3 (Cholecalciferol)): synthesized by sunlight or, found in animal-based foods like salmon and mackerel

According to research, D3D3 is converted into active vitamin D in the body 3 times more efficiently than D2.. So D3 is what we should choose.?

비타민D2는 에르고칼시페롤, D3는 콜레칼시페롤이에요, 약사가 직접 알려드립니다

The recommended intake is 10Âµg (400IU),), and the upper limit intake is 100Âµg (4,000IU), for your reference.!
(*IU stands for International Unit. Think of it as a measure of the potency of vitamin effectiveness here..)

Since vitamin D is fat-soluble, it accumulates in the body..

If you consume excessively, there is a toxicity risk, so be sure to adhere to the upper limit intake amount.!

Note that vitamins E and K are also fat-soluble vitamins..

Since these also have the property of accumulating in the body, intake management is important.,
