Power your body at the cellular source. While standard vitamin B-3 supplements must pass through an extensive conversion process in your digestive tract and liver, Source Naturals NAD+ Coenzymated B-3 Sublingual 25mg delivers active, pre-converted coenzyme fuel directly into your system.
Direct Sublingual DeliveryTo understand why coenzymated vitamin B-3 is superior, think of standard dietary vitamins as crude oil. Crude oil cannot run your car; it must first be piped to a refinery and converted into gasoline.
Common dietary niacin (nicotinic acid or nicotinamide) works the same way. When you swallow ordinary niacin, your liver must invest time and cellular energy to convert it through several biological chemical steps before it becomes Nicotinamide Adenine Dinucleotide (NAD+). If your metabolism is tired, stressed, or aging, this conversion process runs slowly and inefficiently.
Source Naturals Coenzymated B-3 gives your body the finished product. By supplying NAD+ directly in its biologically active coenzyme state, your cells skip the biochemical waiting line and get right to generating energy, maintaining DNA health, and revitalizing everyday cellular performance.
One of the largest hurdles in nutritional science is making sure sensitive coenzymes survive the journey through your gut. When you swallow an intact NAD+ pill, it lands directly in a pool of potent hydrochloric acid and aggressive digestive enzymes inside your stomach. Much of the delicate molecular structure is broken down before it ever reaches your bloodstream.
Sublingual delivery changes the game completely:
Traversing the stomach subjects compounds to gastric acid and bile salts. Once absorbed through the intestinal wall, they go straight to the liver via the portal vein (known as hepatic first-pass metabolism), where a significant portion of active coenzymes are dismantled into basic fragments.
The lining beneath your tongue (oral mucosa) is extremely thin and rich in micro-capillaries. Letting this peppermint lozenge melt naturally under the tongue allows active NAD+ molecules to diffuse straight into the bloodstream, bypassing both digestive destruction and first-pass liver degradation.
Source Naturals developed this specialized formula using a dual-action approach. Each lozenge provides a balanced 25 mg total of active Niacin power built from two complementary ingredients:
The purest biologically functional form of cellular B-3. It acts immediately as an electron carrier inside your cellular engines, participating directly in metabolic reactions that fuel clear thinking, nerve signaling, and physical stamina.
A premium "no-flush" form of niacin consisting of six nicotinic acid molecules bound to a central inositol ring. It releases slowly and steadily, giving your system baseline support without triggering uncomfortable skin redness, burning, or itchiness associated with cheap niacin.
Every second of the day, your heart beats, your brain processes thoughts, and your muscles contract. None of this happens without Adenosine Triphosphate (ATP), often called the chemical energy currency of life. NAD+ is the indispensable molecular carrier that makes ATP production possible.
Inside your cells exist thousands of microscopic power generators called mitochondria. When you eat, carbohydrates and fats are broken down. NAD+ grabs tiny high-energy particles (electrons) from that food, briefly transforming into NADH, and delivers them into the mitochondrial electron transport chain. Once dropped off, the battery resets back to NAD+ to do it again. Without sufficient NAD+, this energy line slows to a crawl, leaving you feeling physically run down and mentally sluggish.
Sirtuins (such as SIRT1 and SIRT3) are specialized regulatory proteins that govern cellular aging, inflammation defense, and mitochondrial renewal. Sirtuins are completely NAD+ dependent: without ample NAD+ in the cell, they cannot turn on or protect your tissues.
Environmental factors like UV radiation, stress, and natural metabolic waste constantly cause microscopic breaks in our cellular DNA. Poly(ADP-ribose) polymerases (PARPs) are guardian enzymes that repair this damage, consuming NAD+ molecules each time they rebuild a damaged strand.
Not all vitamin B-3 supplements function identically in the human body. Here is how Source Naturals Sublingual Coenzymated B-3 stacks up against conventional alternatives:
Natural internal levels of NAD+ drop steadily as we age, often declining by up to 50% between our 20s and 50s. This reduction is linked to slower cellular recovery, mid-day fatigue, and brain fog. This sublingual lozenge is ideal for:
🧠 Mental Clarity & Focus Supports neurotransmitter balance and brain cell bioenergetics for clear, focused thinking without jittery stimulants. ⚡ Afternoon Energy Slumps Replenishes essential coenzymes needed by mitochondria to fuel steady, natural energy without an artificial crash. 🩺 Healthy Aging & Longevity Feeds the sirtuin longevity pathways and cellular DNA maintenance enzymes that help keep biological systems resilient. 🏃 Active Fitness Recovery Facilitates lactic acid processing and efficient muscle tissue oxygen utilization after aerobic or strength workouts.Because this is a specialized sublingual lozenge, how you take it directly impacts how much active NAD+ reaches your bloodstream:
1 Place Under the Tongue: Place 1 lozenge under your tongue or between your cheek and gum. Do not chew or swallow it whole like a common pill. 2 Allow Full Dissolution: Let the tablet dissolve naturally for 2 to 4 minutes. Enjoy the crisp, natural peppermint flavor as the active coenzymes absorb across the mucosal lining. 3 Swallow Naturally & Hydrate: Once dissolved, swallow any remaining saliva normally. For optimal morning focus, take your lozenge first thing in the morning or 30 minutes prior to mental work or physical exercise.Every batch manufactured by Source Naturals adheres to strict Good Manufacturing Practices (cGMP). Below is the complete, unaltered label panel and ingredient specification:
Supplement Facts Serving Size: 1 Peppermint Lozenge Servings Per Container: 30 Amount Per Serving % Daily Value (%DV) NiacinActive Ingredients: Inositol Hexanicotinate (27 mg), Nicotinamide Adenine Dinucleotide (NAD+, 25 mg).
Other (Inactive) Ingredients: Sorbitol, mannitol, stearic acid, natural peppermint flavor, and magnesium stearate.
Ingredient Functions: Sorbitol and mannitol are natural plant-derived polyols that provide a clean, slow-dissolve texture without table sugar. Stearic acid and magnesium stearate ensure even tableting consistency, while natural peppermint oil provides a refreshing taste during sublingual absorption.
At VitaNet®, we believe that medical honesty and transparency are essential for your health decisions. While NAD+ is a naturally occurring coenzyme found in all living cells, please review the following safety guidance:
Precautions & Contraindications:Regulatory Notice: These statements have not been evaluated by the Food and Drug Administration.

No. The famous "niacin flush" (temporary skin tingling, redness, and heat) is caused by high doses of standard crystalline nicotinic acid dilating peripheral blood capillaries. This product utilizes pre-formed Nicotinamide Adenine Dinucleotide (NAD+) paired with Inositol Hexanicotinate, a specialized non-flushing form of vitamin B-3. You can enjoy the cellular benefits without uncomfortable itching or facial redness.
When an intact NAD+ molecule is swallowed, it encounters powerful stomach acids and digestive enzymes that split it into smaller precursors before it reaches your circulation. Dissolving the lozenge under your tongue allows direct absorption through the sublingual mucous membranes directly into capillaries, preserving the active coenzyme structure and avoiding first-pass hepatic degradation.
Because sublingual absorption takes effect quickly, many users report feeling improved mental alertness, focus, and clean physical stamina within 30 to 60 minutes of dissolution. Deeper benefits—such as enhanced cellular recovery, sustained endurance, and healthy aging support—compound progressively over 3 to 6 weeks of daily, consistent use.
Nicotinamide Riboside (NR) and Nicotinamide Mononucleotide (NMN) are biological precursor building blocks that your cells must convert inside the body to manufacture NAD+. NAD+ (Nicotinamide Adenine Dinucleotide) is the final, active coenzyme that mitochondria and sirtuin enzymes actually consume. Source Naturals gives you the active coenzyme directly in sublingual form.
While it is safe to swallow, doing so significantly lowers its effectiveness. Chewing or quickly swallowing the tablet sends the delicate NAD+ coenzyme into stomach acid where much of it is broken down. To receive the maximum cellular benefit, always let the tablet dissolve slowly under your tongue.
