A NAD infusion appointment should begin well before the cannula is inserted. People searching for how to prepare for NAD infusion are often focused on food, water and what to bring. Those details matter, but the most meaningful preparation is confirming that treatment is appropriate, that the provider has a clear clinical protocol and that you understand what the session may involve.
NAD, short for nicotinamide adenine dinucleotide, is a coenzyme involved in cellular energy metabolism. It is sometimes administered intravenously in private clinical settings. Research into intravenous NAD+ for wellbeing, fatigue, recovery and longevity remains limited, and treatment should not be presented as a proven remedy for medical conditions. A responsible clinic will make this distinction clear, assess your circumstances individually and avoid promises about outcomes.
How to prepare for a NAD infusion safely
Preparation starts with an honest clinical consultation. This should cover your current health, relevant medical history, allergies, previous reactions to infusions or injections, and all medicines and supplements you take. Do not assume that a treatment marketed as a nutrient or wellness infusion is automatically suitable for everyone.
Tell the clinician about any diagnosed condition, recent illness, current symptoms or planned procedure. It is also sensible to disclose whether you are pregnant, breastfeeding or trying to conceive. These are circumstances in which the evidence base and clinical decision-making may be more limited, and the provider may advise against proceeding or seek further medical input.
If you have had fainting episodes, difficult veins, needle anxiety or a past reaction during an IV treatment, say so before the appointment. This allows the clinic to plan appropriately, for example by allowing more time, using positioning that reduces the risk of a vasovagal episode, or discussing whether IV treatment is the right route for you.
A consultation should also establish the purpose of treatment. Persistent exhaustion, reduced exercise tolerance, sleep disturbance or brain fog can have many causes, including conditions that need medical assessment. An infusion service should not replace appropriate investigation by your GP or another relevant clinician, particularly where symptoms are new, severe, worsening or accompanied by weight loss, chest pain, breathlessness, fever or neurological changes.
Check the provider’s clinical arrangements
The preparation process is also an opportunity to assess the clinic. In the UK, safe IV care depends on more than a comfortable treatment room. Ask who will assess you, who will administer the infusion, what training and professional registration they hold, and what medical oversight is available if you become unwell.
The clinic should be able to explain the proposed product, its source, storage arrangements, dose, dilution and infusion rate in clear terms. They should also describe consent, record-keeping, infection prevention and emergency procedures. Depending on the product and the clinical context, appropriate prescribing, supply and administration arrangements should be in place. You should never feel pressured to proceed before your questions have been answered.
A careful provider will explain that NAD infusions are commonly delivered slowly. The pace is not merely a matter of convenience. Some people experience discomfort or unpleasant symptoms when an infusion runs too quickly, so a protocol may involve starting cautiously and adjusting the rate based on how you feel. The exact approach should be determined by the treating clinician, not by a generic online schedule.
The day before and the morning of treatment
Unless the clinic has given different instructions, aim for normal, regular meals and good hydration in the 24 hours before your appointment. Arriving dehydrated, having skipped meals or feeling unwell can make any cannulation appointment less comfortable and may increase the likelihood of light-headedness.
Choose a balanced meal before attending rather than fasting unnecessarily. A combination of carbohydrate, protein and fluid is usually more practical than a large, rich meal immediately before the appointment. If you have diabetes, a restricted diet, kidney disease, heart failure or another condition that affects fluid or food intake, follow your established clinical advice and ask the infusion provider for individual guidance. Do not increase fluid intake beyond what is appropriate for your condition.
Avoid heavy alcohol intake beforehand. Alcohol can contribute to dehydration, affect sleep and make it harder to judge whether symptoms on the day are related to the infusion, alcohol use or an underlying issue. Arrive rested where possible, but do not cancel essential sleep medication or alter your prescribed routine without advice from the clinician who manages it.
Take regular prescribed medicines as directed unless your prescriber or the infusion clinic has specifically advised otherwise. Do not stop medicines to make yourself eligible for an infusion. Provide the clinic with an up-to-date list, including non-prescription medicines, herbal products and supplements. This gives the clinician the information needed to consider potential interactions, overlapping ingredients and whether another source of advice is required.
Wear loose, comfortable clothing that allows easy access to your arm. If you are prone to feeling cold during infusions, take an extra layer. Bringing water and a small snack may be useful if the clinic permits it, although the provider should set out what is appropriate within its treatment area.
Plan for the appointment, not just the infusion
NAD sessions may take longer than a standard hydration infusion because the rate may need to be kept gradual. Ask in advance how long to allow, including assessment, cannulation, observation and discharge. Avoid scheduling the appointment immediately before an intense workout, a long journey, a demanding work commitment or an event where you cannot respond sensibly to feeling unwell.
Whether you should drive afterwards depends on how you feel, the length of the treatment and the clinic’s advice. If this is your first NAD infusion, arranging a lift or leaving enough time to rest is a cautious choice. Do not drive if you feel faint, nauseated, unusually tired or unable to concentrate.
Bring photo identification if requested, plus details of your GP and any relevant specialists. If you have recent test results or a clinical letter that helps explain a condition relevant to treatment, ask the clinic whether it would be helpful to bring it. The aim is not to create paperwork for its own sake, but to ensure decisions are based on adequate information.
During the infusion: report symptoms early
Cannulation can cause brief discomfort, bruising or local irritation. Once the infusion has started, the clinician should check how you are feeling and ensure the cannula site remains comfortable. Tell them promptly about burning, pain, swelling, redness or leaking around the site, as these can indicate a problem requiring assessment.
Some people report nausea, abdominal discomfort, chest tightness, headache, flushing, restlessness or a feeling of pressure during NAD administration, particularly if it is delivered too rapidly. These symptoms should not be ignored or treated as something you simply need to push through. The clinician may pause or slow the infusion and assess you. Severe symptoms, breathing difficulty, chest pain, collapse, widespread rash or swelling require urgent clinical attention.
Stay seated or reclined as advised. Use the appointment to ask practical questions about the amount administered, the rate used, any symptoms you experienced and what follow-up is recommended. This information is useful if you and the clinician later decide that a further appointment is appropriate.
Aftercare and when to seek advice
Follow the clinic’s aftercare instructions, which should be specific rather than vague. You may be advised to continue normal hydration, eat regularly and avoid strenuous activity for the rest of the day if you feel tired or light-headed. It is reasonable to resume ordinary activities only when you feel well enough to do so.
Mild bruising around a cannula site can occur, but worsening pain, increasing redness, warmth, swelling, discharge or a fever should be assessed promptly. Seek urgent medical care for severe or rapidly developing symptoms, including difficulty breathing, chest pain, facial swelling or fainting.
Do not judge the value of treatment solely by a same-day feeling, whether positive or negative. Record relevant effects, symptoms and any concerns, then discuss them with the clinic before booking another session. Careful preparation for NAD infusion is ultimately about informed consent, appropriate pacing and a provider willing to put clinical judgement ahead of a sale.
