How many Memodyne capsules should you take a day?
One capsule a day is the full dose. The label gives the directions in two sentences: “As a dietary supplement, take one (1) capsule daily with an 8 oz. glass of water. For best results, take 20-30 minutes before a meal with 8 oz of water or as directed by your healthcare professional.”
So the routine has three parts. One capsule, one 8 oz glass of water, and a short wait before you eat. Nothing on the label says to take more on busy days or to build up slowly.
- 1capsule a day
- 8 ozglass of water
- 20-30minutes before a meal
- 30capsules in each bottle
How to take Memodyne, step by step
The whole routine takes about a minute. Let the steps play, or tap any step to jump to it.

What time of day should you take it?
Pick a meal you eat every day, then take the capsule 20 to 30 minutes before it. The dial marks a breakfast window, since a morning meal is an easy one to tie a habit to.

Tips for a steady habit
Keep the bottle next to your water glass or coffee maker. Seeing it each morning is a simple reminder.
Set a phone alarm for the same time each day. Some people take the capsule, then start the kettle or toast. By the time breakfast is ready, the 20 to 30 minutes have passed.
Work nights? Use your first meal after waking instead. The clock hour matters less than doing it the same way each day.
Why does the label say before a meal?
The label does not explain the reason. It says only that the 20 to 30 minute gap gives the “best results”, and it allows another plan “as directed by your healthcare professional”.
So treat the meal timing as the maker's preference, not a strict medical rule. If your doctor suggests a different time, follow your doctor. If the capsule bothers your stomach before food, ask your pharmacist whether taking it closer to the meal is fine.

What if you miss a capsule?
Skip the missed capsule and carry on as normal. Never take two in one day. The label says “Do not exceed recommended dose”, and a double dose would break that rule.
- You remember before lunch
Take it now, 20 to 30 minutes before lunch. Then go back to your usual time tomorrow.
- You remember late in the evening
Leave it. Take your normal capsule tomorrow morning.
- You remember the next day
Take one capsule at your usual time. Leave a gap in your log for the missed day.
- You missed several days
Start again with one capsule a day. There is no catch-up dose.
Never double up
One capsule a day is the most the label allows. If you feel tempted to take more, talk with your doctor about why.
Can you take it with your medicines?
Ask first if you take any of the medicines below. Bring the bottle so your doctor or pharmacist can read the full label. Never stop or change a prescription to make room for a supplement.
| If you take | Why it matters | A question to ask |
|---|---|---|
| Blood pressure medicine | Arginine and citrulline may lower blood pressure and add to the drug (MSKCC, Arginine) | Could my pressure drop too low? |
| Nitroglycerin or other nitrates | L-arginine with nitroglycerin might drop blood pressure too far (Mayo Clinic, L-arginine) | Is this safe with my chest pain medicine? |
| ED pills such as sildenafil | L-arginine with sildenafil might drop blood pressure too low (Mayo Clinic, L-arginine) | Should I avoid it on days I use my ED pill? |
| Any heart medicine, or a past heart attack | An arginine trial after heart attacks found no benefit and more deaths (Schulman et al., JAMA 2006) | Is any arginine product right for me? |
The who it is for page has a quick checklist, and the side effects page lists what to watch for.
How should you store the bottle?
The label says: “Store in a cool, dry place away from heat and light.” A cupboard away from the stove, oven and sunny windows fits that well.
A bathroom shelf is a poor spot. Steam from the shower adds damp air each day.
Storage checklist
- Keep the cap closed tight between doses
- Leave the capsules in the original bottle so the label stays with them
- Keep it out of reach of children and pets
- Do not use it if the safety seal is damaged or missing, as the label says
- Check that the capsules look the same as when you opened the bottle
How do you take it when you travel?
Pack the bottle in your carry-on bag, not checked luggage. That keeps it with you and away from hot cargo holds or car trunks.
A weekly pill box is handy for short trips. Still, the original bottle holds the label, which helps if anyone asks what it is.
Crossing time zones? Take your capsule before a meal in the new local time. On the travel day itself, take no more than one capsule, so two never land close together.
How long does one bottle last?
One bottle lasts 30 days at one capsule a day. Packs come in 2, 3 or 6 bottles; the pricing page lists each one.
| Amount | Capsules | Lasts | Note |
|---|---|---|---|
| 1 bottle | 30 capsules | 30 days | Comes in the 2, 3 or 6-bottle packs |
| 2-bottle pack | 60 capsules | 60 days | Covers the 60-day window |
| 3-bottle pack | 90 capsules | 90 days | 30 days past the window |
| 6-bottle pack | 180 capsules | 180 days | About six months |
