Can You Take MemoVance Pro With Blood Pressure or Thyroid Medicine?
People ask whether they can take MemoVance Pro every day and with their medicines. This article gives the label caution, the two interactions worth knowing and the questions to take to a pharmacist.
Quick answer
Tell your prescriber before the first capsule if you take a blood pressure medicine, a nitrate or a PDE-5 inhibitor, because four of the seven rows are vasodilating amino acids. The 18 mg calcium row is too small to interfere with levothyroxine. Ask your doctor about anything else.
- Label caution: do not exceed the recommended dose. Anyone pregnant or nursing, children under 18 and anyone with a known medical condition should consult a physician.
- Four rows are vasodilating amino acids. At 200 mg of arginine the effect is likely slight.
- The calcium row is 18 mg. The levothyroxine work used 500 to 1,200 mg.
- Neither the niacin flush nor the beta-alanine tingle occurs at these amounts.
- Daily use is the label's instruction: one capsule a day with an 8 oz glass of water.
Can you take MemoVance Pro every day?
Yes, that is the instruction on the label. Take one capsule daily with an 8 oz glass of water. The label suggests 20 to 30 minutes before a meal, or as your healthcare professional directs.
Do not take more. The label says not to exceed the recommended dose, and a 30-capsule bottle assumes one a day. If you miss a day, simply take the next one at the normal time.
Who does the label say should check first?
- Pregnant or nursing mothers.
- Children under the age of 18.
- Anyone with a known medical condition, who should consult a physician before using this or any dietary supplement.
The product is for healthy adults aged 18 and over. Keep children away from it, and do not use a bottle whose safety seal is damaged or missing.
Can you take it with blood pressure medicine?
Talk to your prescriber first. Four of the seven rows are amino acids that relax blood vessels. A blood pressure medicine does something similar on purpose, so an added effect is a fair question.
The scale is small. The pooled trials of arginine found an effect on blood pressure only at 4 g a day or more, and this capsule has 200 mg of arginine base. Even so, a prescriber should hear about it rather than discover it.
What about nitrates and PDE-5 inhibitors?
The same advice applies, and the same reason. Nitrates and PDE-5 inhibitors work on the same relaxing pathway. Tell your prescriber or pharmacist before the first capsule, and let them decide whether the combination needs any change.
Do not wait for a symptom. If you feel lightheaded when you stand up after starting, stop and ask for the combination to be reviewed.
Can you take it with thyroid medicine?
The calcium row is good news here. Calcium carbonate can bind levothyroxine in the gut, but the interaction studies used 500 to 1,200 mg. This capsule has 18 mg, which is far too small to interact.
You do not need to rearrange your morning around this row. Still, mention the capsule at your next appointment, as you would with any supplement.

Are there other side effects to watch for?
No adverse event report for MemoVance Pro itself has been found in the sources, and the amounts are small. The most plausible complaint is a mildly unsettled stomach, which some people notice from amino acids on an empty stomach. If that happens, you could take the capsule with the first mouthful of breakfast and ask your pharmacist.
Interactions beyond the two named here are not mapped. An absence of a known interaction is weaker than a proven absence, so ask before you combine.
MemoVance Pro is a dietary supplement. It is not a drug, it is not FDA approved, and no supplement is. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease. For medical questions, for medicines you already take, or if you are pregnant or nursing, ask your doctor or pharmacist first.
When should you stop and ask for help?
- Any rash, swelling or trouble breathing: stop and seek urgent care.
- Nausea that lasts past the second week.
- Lightheadedness on standing, if you take a blood pressure medicine.
- Anything new that begins within days of the first capsule.
- A memory change that other people have noticed: see a doctor about that, not a supplement.
Frequently asked questions
Can I take MemoVance Pro daily?
Yes. The label says one capsule daily with an 8 oz glass of water. Do not exceed the recommended dose.
Is MemoVance Pro safe with blood pressure medicine?
Tell your prescriber first. Four of the seven rows are vasodilating amino acids, and the effect at 200 mg of arginine is likely slight.
Can I take MemoVance Pro with levothyroxine?
The calcium row is 18 mg, far below the 500 to 1,200 mg used in the interaction work, so it is too small to interfere. Mention it to your doctor anyway.
Does MemoVance Pro cause a niacin flush?
No. It has 7.5 mg NE of niacin. A flush needs doses in the hundreds of milligrams.
Are there any MemoVance Pro side effects?
No adverse event report has been found. A mild stomach upset on an empty stomach is the most plausible complaint.
Who should not take MemoVance Pro?
Anyone under 18, anyone pregnant or nursing, and anyone with a known medical condition until a physician has been consulted.
Our view
The amounts are small, and that helps. The label caution and the vasodilating rows still mean a short chat with your prescriber is wise.
The calcium row is the pleasant surprise. It is tiny, so it does not get in the way of thyroid medicine.
As with any supplement, your own doctor knows your history. Use this article to arrive with better questions, not to skip the appointment.
