NAD+ Therapy

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme derived from vitamin B3. It occurs naturally and is found in every cell of the body. Its key role is to slow cellular degeneration and protect cells from damage: it drives the conversion of food into cellular energy and supports cell regeneration, keeping cells young and resilient. NAD+ can be described as a compound that restores the body down to DNA level, helping to prevent the deterioration of every major system — especially the nervous system and brain, which govern perception, thought and memory.

Studies show that NAD+ falls to around 50% of youthful levels by middle age, and to less than 20% in older age. That decline shows as visible ageing, wrinkles and deeper lines, followed by deterioration of the nervous system and brain, along with increased risk of heart disease, diabetes, immune deficiency, obesity and fertility problems.

• Supports the nervous system and brain by increasing energy and stimulating cell regeneration — reducing brain fog, improving memory and helping to protect against dementia and Alzheimer's disease
• Slows ageing and keeps skin cells youthful, helping to prevent premature wrinkles
• Slows the ageing of cells throughout the body so organ systems function normally, keeping you strong, less prone to illness and quicker to recover
• Supports the metabolic system, keeping weight stable as you get older
• Reduces the risk of age-related disease, including diabetes, high blood pressure, cardiovascular disease, bone conditions and eye and vision problems

NAD+ therapy replenishes a coenzyme that improves cellular performance. It works in two main ways: converting cellular energy, and keeping cells strong and functioning at full capacity.

• NAD+ stimulates cell repair at DNA level, extending cell lifespan and keeping cells robust.
• NAD+ activates sirtuin proteins, which play a key role in slowing ageing and regulating cellular ageing. When sirtuins work fully they protect cells from damage, reduce intracellular inflammation and support longer cell life.
• NAD+ restores mitochondrial function — the powerhouse of the cell — so cells repair and renew themselves efficiently and organ systems including the heart, nervous system, respiratory system and endocrine system work normally.

• Some patients experience headache, dizziness, a fast heartbeat, chest tightness or mild nausea during the infusion. Tell the doctor and the infusion rate can be reduced; these effects usually settle within 10–20 minutes of finishing.
• There may be marking or irritation at the infusion site, which resolves on its own.
• Where NAD+ is administered outside an accredited clinic or by someone who is not a qualified doctor, inappropriate or non-standard dosing can cause allergic reactions, nausea, vomiting, chest tightness or breathing difficulty, and unclean equipment can cause infection.

• Sleep sufficiently — at least 6–8 hours a night so the body can rest and repair.
• Eat a healthy, balanced diet so the body receives the full range of vitamins and minerals.
• Drink enough clean water — at least 1.5–2 litres a day.
• Exercise regularly to build strength from within.
• Stop smoking and avoid alcohol to build long-term health.

Every NAD+ programme at LINNA Clinic is prescribed and supervised by doctors experienced in longevity medicine. Dosage is individualised, the infusion rate is adjusted to your comfort, and vital signs are monitored throughout. We use pharmaceutical-grade NAD+ from trusted sources, in a licensed clinical environment.

Blood pressure and heart rate are measured before every infusion. If anything feels unusual during treatment, the infusion rate is adjusted immediately, or stopped if necessary. Vital signs are checked again afterwards, so you leave the clinic knowing everything is normal. A doctor reviews your health history and any allergies before your first drip.
