Why Two NAD+ Pathways in One Capsule?
Your body uses multiple biochemical routes to produce NAD+ — the coenzyme central to cellular energy, mitochondrial function and healthy ageing. NAD+ levels naturally decline from your 30s onwards. Most NAD+ supplements target a single pathway. This formula covers two simultaneously — giving your body more than one biochemical route to NAD+ production.
Pathway 1 · Salvage Pathway
NMN 400mg
Nicotinamide Mononucleotide → NAD+
NMN is a direct NAD+ precursor — one metabolic step from NAD+. Absorbed via the Slc12a8 intestinal transporter (confirmed 2023). Converts via NMNAT enzymes in tissues including skeletal muscle, liver and kidney. Our NMN is independently tested by Eurofins at 99.99% purity via HPLC. Batch PC-SE260410. CAS 1094-61-7 · C₁₁H₁₅N₂O₈P.
Pathway 2 · Preiss-Handler Pathway
Niacin B3 100mg
Nicotinic Acid → NAMN → NAD+
Nicotinic Acid enters the Preiss-Handler pathway — a separate biochemical route to NAD+ via NAPRT enzyme. It also carries 5 authorised UK health claims for energy metabolism, nervous system, tiredness, skin and cholesterol — making it uniquely versatile alongside NMN. 100mg per capsule = 625% NRV.
✅ Authorised GB NHC Claims — Nicotinic Acid (Niacin B3)
5 Legally Verified Health Claims — Assessed by Scientific Panels
✅Niacin contributes to normal energy-yielding metabolism
✅Niacin contributes to the normal functioning of the nervous system
✅Niacin contributes to a reduction of tiredness and fatigue
✅Niacin contributes to the maintenance of normal skin and mucous membranes
✅Niacin contributes to the maintenance of normal cholesterol levels
These are the only health claims authorised for Nicotinic Acid under the GB Nutrition and Health Claims Register. They are legally verified facts — not marketing. NMN (Nicotinamide Mononucleotide) has no authorised EU/UK health claims. All NMN content is compositional and research context only. The cholesterol claim applies at 16mg NRV and above — this product provides 100mg (625% NRV).

🔥 Important — The Niacin Flush. Read Before Taking.
This formula contains 100mg Nicotinic Acid (Niacin B3). You may experience a temporary warm, tingling or flushing sensation on the skin — typically face, neck and chest — lasting 15–30 minutes after taking your capsule. This is the Niacin Flush.
✅ What the flush IS
A natural, harmless physiological response
Caused by prostaglandin-mediated vasodilation
A well-documented expected response to Nicotinic Acid
Reduces in intensity with consistent daily use
❌ What the flush is NOT
Not an allergic reaction
Not harmful or dangerous
Not caused by the NMN component
Not permanent — typically 15–30 minutes
💡 To reduce the flush: Take your capsule with a full meal. The flush typically reduces in intensity over the first 1–2 weeks of consistent daily use as your body adapts to Nicotinic Acid.
What Is NAD+ and Why Does It Matter?
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme present in every cell in your body — central to over 500 enzymatic reactions including cellular energy production (ATP synthesis), DNA repair and the activation of sirtuins. NAD+ levels naturally decline from your 30s onwards. You cannot supplement NAD+ directly. Instead you supplement oral precursors that convert into NAD+ through specific metabolic pathways.
🔋 Energy Metabolism — Authorised Claim
Niacin contributes to normal energy-yielding metabolism — legally verified GB NHC Register claim. NAD+ is central to how mitochondria convert food into cellular energy (ATP). Consistent daily use over weeks is key.
🧠 Nervous System — Authorised Claim
Niacin contributes to the normal functioning of the nervous system — authorised claim. NAD+ is involved in neuronal energy metabolism. Niacin is used in clinical practice for neuroprotection research dating back to 1955.
⚡ Tiredness & Fatigue — Authorised Claim
Niacin contributes to a reduction of tiredness and fatigue — authorised claim. B3 Niacin is a key component of energy metabolism and cellular ATP production. 100mg per capsule = 625% NRV.
❤️ Cholesterol — Authorised Claim
Niacin contributes to the maintenance of normal cholesterol levels — authorised claim. Nicotinic acid has been used in clinical practice for cholesterol management since 1955 — the longest-standing lipid-related supplement use in evidence.

Frequently Asked Questions
What is the difference between NMN and Niacin B3?
NMN (Nicotinamide Mononucleotide) and Nicotinic Acid (Niacin B3) are both NAD+ precursors but convert via different biochemical pathways. NMN enters the Salvage Pathway — one step from NAD+. Nicotinic Acid enters the Preiss-Handler Pathway — a separate route. Niacin B3 has 5 authorised UK health claims. NMN has no authorised claims but has an extensive NAD+ precursor research base.
What is the niacin flush and will it happen to me?
The niacin flush is a temporary warm, tingling or red sensation on the skin after taking Nicotinic Acid. Caused by prostaglandin-mediated vasodilation — harmless, typically 15–30 minutes. Reduces with consistent daily use. Taking with a full meal significantly reduces it. Not everyone experiences it equally — the first week tends to be the most pronounced.
Is the NMN in this product Eurofins tested?
Yes. Same Eurofins-verified batch (PC-SE260410) as our standalone NMN 500mg capsules — 99.99% purity confirmed via HPLC. Certificate of Analysis available on request — message us.
What are the 5 authorised health claims for this product?
Five authorised claims apply to the Niacin B3 (Nicotinic Acid) component: normal energy-yielding metabolism · normal functioning of the nervous system · reduction of tiredness and fatigue · maintenance of normal skin and mucous membranes · maintenance of normal cholesterol levels. NMN has no authorised EU/UK health claims. All NMN content is compositional and research context only.
How does this compare to your NMN 500mg capsules?
Our NMN 500mg capsules contain only NMN at maximum dose — 500mg per capsule, Eurofins-tested, zero fillers. This product contains 400mg NMN plus 100mg Nicotinic Acid for dual pathway coverage and 5 authorised B3 claims. Choose NMN 500mg for maximum NMN dose. Choose this product for dual pathway coverage and the additional authorised Niacin B3 benefits in one capsule.
Where can I buy NMN 400mg + Niacin B3 100mg UK?
Direct from chargeproducts.co.uk with same-day dispatch and free UK delivery. Also on eBay UK at ebay.co.uk/itm/154052846875. Both channels ship from the same UK facility using the same product.
Is this suitable for vegans?
Yes. HPMC capsule shell — 100% plant-derived, no gelatin. Vegan, vegetarian, gluten-free, non-GMO, sugar-free, dairy-free.
What does niacin do for cholesterol?
Niacin (Nicotinic Acid) contributes to the maintenance of normal cholesterol levels — this is an authorised UK health claim per the GB NHC Register. Nicotinic acid has been used in clinical and nutritional practice for lipid metabolism support since 1955 — it is one of the longest-established B vitamin applications in evidence. Our product provides 100mg Nicotinic Acid per capsule (625% NRV), well above the 16mg NRV threshold at which this claim applies.
