Open a bottle of the drink, turn to the ingredient list, and you will see iron appear three times: heme iron, ferrous glycinate, and sodium iron EDTA. Many people's first reaction is—what is the difference between these three? How much iron is there in total per serving?
First, the conclusion: in the currently verifiable supplier materials, only the names of these three iron sources are listed. The amount added for each is not given, nor is the total iron content per serving. Therefore, based on these materials alone, it is impossible to calculate or compare the difference in iron content per serving. What can truly answer this question is the nutrition facts table on the actual retail packaging, where the iron content per serving will be stated.
The three iron sources: where the names differ
Heme iron comes from animal-derived ingredients and is in porphyrin iron form; ferrous glycinate is a product of iron combined with glycine and is often classified as amino acid chelated iron; sodium iron EDTA, abbreviated NaFeEDTA, is a complex of iron combined with EDTA. The three have different chemical forms. This is the information visible on the ingredient list.
But a different form does not mean that the content per serving is higher or lower. The materials do not give the amount added for each of the three, nor do they explain the ratio among them. The ingredient list is arranged in descending order by amount added, but if the added amounts of all three iron sources are very small, they may all appear near the end of the ingredient list, and the order alone cannot be used to infer specific values.
Iron content per serving: this number is not in the materials
This is the easiest pitfall when purchasing: treating the names of iron sources in the ingredient list as evidence of iron content. The names only indicate what was used, not how much was used.
The product materials give the added amounts of some other ingredients, such as red date extract 6000 mg/bottle, red ginseng extract 200 mg/bottle, blood protein peptide 10 mg/bottle, pyrroloquinoline quinone disodium salt 2 mg/bottle, and bird's nest peptide 500 μg/bottle. But the three iron sources are not followed by values. The boundary of the materials is here: iron sources have names, no added amounts, and no iron content per serving.
If you need to know how much iron you consume per serving, the only reliable way is to check the nutrition label on the actual sales packaging. Labels may differ by batch or by retail version, so the box in your hands should be the standard.
What to look at first when purchasing
First, look at the iron content in the nutrition facts table, not at how many times iron appears in the ingredient list.
Second, look at the recommended daily serving. The materials recommend drinking after meals, and the daily serving should follow the label on the actual sales packaging. Iron content should be calculated together with how many bottles you drink per day; looking only at the value per bottle is not enough.
Third, pay attention to usage restrictions. Infants and young children, pregnant women, breastfeeding women, children under 14 years old, and people allergic to fish should not use it. It contains animal-derived ingredients and is not vegetarian. If you are taking medication or have special dietary needs, ask a healthcare professional before purchasing.
Fourth, do not equate "contains iron sources" with "iron supplementation effect." This is a food, not a medicine, and it cannot replace a balanced diet. The materials do not promise improvement effects or a number of days to see results after drinking. If you continue to feel tired, unwell, or suspect iron deficiency, you should seek professional evaluation first rather than judging by yourself based on a bottle of drink.
What this drink itself is
Red Ginseng Ejiao Peptide is a ready-to-drink food, 50 mL × 7 bottles/box. Ingredients include water, red date extract, red ginseng extract, sea cucumber peptide, American ginseng powder, ejiao peptide, codonopsis powder, reishi powder, poria powder, salmon hydrolyzed protein peptide, blood protein peptide, fish maw oligopeptide, black-bone chicken peptide, astragalus powder, lily powder, bird's nest peptide, longan powder, concentrated goji berry juice, concentrated red pomegranate juice, pyrroloquinoline quinone disodium salt, three iron sources, niacinamide, citric acid, and sucralose.
Shake well before drinking, open the cap and drink directly, and it is recommended to drink after meals. Store in a cool, dry place and avoid direct sunlight. The shelf life is 18 months; see the bottle for the expiration date. The ingredients contain red date extract, concentrated fruit juice, and the sweetener sucralose. This is not a sugar-free claim, and the sugar content should be based on the actual nutrition label.
Turn taking care of yourself into a small habit
Rather than struggling over which of the three iron sources is greater or lesser, it is better to first confirm whether you can read the iron content per serving from the label. If you cannot read it, do not draw a conclusion yet.
If you decide to try it, treat it as one option in your daily diet, follow the daily serving stated on the packaging, and do not increase the amount on your own. Drinking after meals, shaking well, and opening the cap—making these actions routine is easier to stick with than studying the order of the ingredient list.
When purchasing, remember one thing: the ingredient list tells you what was used, while the nutrition facts table tells you how much there is per serving. The two cannot replace each other.
