Daily Value Not Established Meaning, With the Melonex Label
The daily value not established meaning is simple: no official daily target exists for that ingredient, so the label cannot print a percentage. On the Melonex label, a dagger beside the 500 mg proprietary blend carries this note. It says nothing about safety or benefit. It only means there is no yardstick to compare the blend against.

No. 01The words
What does daily value not established mean on a label?
Daily value not established means no official daily target has been set for that ingredient, so the panel shows a dagger instead of a percentage.
The meaning of daily value not established starts with the daily value itself. A Daily Value is a recommended amount of a nutrient to eat, or not to go past, in a day. The percent figure tells you how much one serving adds toward it (FDA, Daily Value reference guide).
Vitamin C has one. Many amino acids do not, because nobody has set a target for them.
When a line has no target, the label prints a symbol and a short note instead of a number. On Melonex that note reads "† Daily Value Not Established", next to the 500 mg blend.
It is not a sign that the amount is too high or too low. It means the scale you would use to judge it does not exist.
No. 02The dagger
Why does the Melonex label put a dagger beside the blend?
The dagger points to the note that no Daily Value is set for the blend, because the label lists three amino-acid forms with no target for any of them.
Let's read the panel the way a pharmacist would. One capsule is one serving. Under that sits a single line, the proprietary blend at 500 mg.
Three names follow, in this order: L-citrulline DL-malate, L-arginine alpha-ketoglutarate dihydrate and L-arginine HCL. Their single amounts are not printed, and the rules allow that for blends (21 CFR 101.36).
So the split between the three names is hidden, and so is any percentage. You get one number, 500 mg, and nothing to compare it with.
No. 03Worked example
How is a Melonex line different from a vitamin line?
A vitamin line gives an amount and a percent of a daily target, while the Melonex blend gives one combined weight and a dagger.
| Question you might ask | Line with a Daily Value | Melonex blend line |
|---|---|---|
| Is the amount printed? | Yes, for each nutrient | Only the total, 500 mg |
| Is a percent shown? | Yes | No, a dagger instead |
| Can I tell if one serving is a little or a lot? | Yes, from the percent | No yardstick exists |
| Can I see each ingredient's share? | Yes | Not printed |
| What can I still work out? | Daily intake | A ceiling for each name, from the order |
That last cell is the useful one. Names run from most to least by weight, so citrulline DL-malate is at most 500 mg, arginine alpha-ketoglutarate at most 250 mg and arginine HCL at most 167 mg. These are ceilings, not amounts. The ingredient guide has the full table.
No. 04Words vs evidence
What can a label with no Daily Value really promise?
It can promise only what it states, and the claims on the front stamps still need evidence that matches the product.
The front stamps say "Heart Support*", "Circulation Support*" and "Natural Formula*". The asterisk sends you to the line saying FDA has not evaluated them. Health claims need sound human evidence that fits the dose and form sold (FTC, Health products guidance).
Trials of these amino acids used grams a day. A capsule holds at most hundreds of milligrams, and no trial tested Melonex itself. The dagger changes none of that.
- Label stamp“Heart Support*”No trial has tested Melonex. Arginine after a heart attack raised deaths in one trial, so the word heart needs a doctor's context, not a capsule. (VINTAGE MI trial (ACC summary)) (FDA 101: Dietary supplements)
- Label stamp“Circulation Support*”Arginine and citrulline are studied for blood vessels and pressure at grams a day. A capsule holds at most 500 mg of the first line. (Dong 2011, arginine and BP) (Barkhidarian 2019, citrulline and BP)
- Label stamp“Natural Formula*”The lines are amino acids and their salts. Natural does not always mean safe, and the label does not say how they were made. (NCCIH, Using supplements wisely)
- Label front“ADVANCED SUPPORT”Brand wording. No study, dose or result stands behind the word advanced. (FTC, Health products guidance)
- Facts panel“Proprietary Blend 500 mg”Single amounts are hidden, which the law allows. The order gives ceilings: at most 500, 250 and 167 mg. (21 CFR 101.36)
- Label line“Manufactured in an FDA registered facility”Registration of a building is not approval of a product. FDA does not approve supplements. (FDA, Is it really FDA approved?)
- FDA statement“not intended to diagnose, treat, cure, or prevent any disease”The label says it plainly: this is a supplement. Keep taking prescribed blood pressure medicine. (FDA 101: Dietary supplements)
Wording as printed on the Melonex label. The asterisk on each stamp points to the FDA statement. Health claims need competent and reliable scientific evidence that matches the product (FTC, Health products guidance).
No. 05Your next step
How should you use a daily value not established note when you shop?
Treat the note as a cue to ask three questions: what is in it, how much, and who checks.
Find the names
Read the order of the blend. The first name is the heaviest.
Work out the ceiling
Divide 500 by the place number. That gives the most each name can hold.
Ask about your medicines
Arginine and citrulline may add to blood pressure drugs, nitrates and sildenafil-type drugs (Mayo Clinic, L-arginine). Check with your doctor or pharmacist before starting.

Melonex is a dietary supplement, not a treatment. Ask your doctor or pharmacist first if you take a nitrate for chest pain, an erectile-dysfunction drug such as sildenafil, any blood pressure medicine, a potassium-sparing diuretic, a blood thinner or a diabetes medicine, or if you have had a heart attack. Arginine and citrulline can push blood pressure down further. Keep taking prescribed medicine. See side effects and interactions.
No. 07FAQ
Melonex questions people ask
Is daily value not established the same as zero?
No. It means no official daily target exists, not that the amount is zero. The Melonex blend holds 500 mg in total. The dagger only explains why the line shows no percent.
Why can a supplement hide the amount of each ingredient?
The labeling rule for proprietary blends asks for the blend's total weight and the names in order of weight, not each single amount. That is why the Melonex label shows 500 mg and three names only.
Can I work out how much arginine is in a Melonex capsule?
Only as a ceiling. Arginine alpha-ketoglutarate can hold at most 250 mg and arginine HCL at most 167 mg per capsule, based on the printed order. Split three ways evenly, that is about 167 mg each.
