The Codeage Liposomal NAD+ Ultra stacks 500 mg of NAD+ per serving with quercetin, trans-resveratrol, and betaine anhydrous in a liposomal phospholipid complex. This is not a simple nicotinamide riboside capsule—it delivers active NAD+ alongside sirtuin-activating resveratrol and methylation-supporting betaine. Users in their 60s report noticeable skin improvements, including reduced crepe texture on forearms and around the mouth, along with less brain fog after several weeks.

The formula also includes riboflavin and methylcobalamin (B12), which support the methylation cycle that NAD+ relies on for recycling. The liposomal coating uses non-GMO sunflower oil rather than soy lecithin, making it suitable for soy-sensitive diets. Each bottle provides 90 capsules, which at the recommended serving size lasts 45 days.

Users consistently mention that effects build gradually over two to four weeks rather than hitting immediately. No reports of jitters or crashes suggest stable NAD+ elevation. Some users note it pairs well with other supplements like NAC and probiotics without negative interactions.

Bulk Essentials packs 10 mg of NAD+ per spray into a 10 mL bottle yielding 100 total sprays. This is the highest per-spray concentration in this lineup, designed for users who want fewer daily applications and a denser dose. The formula contains only NAD+,
purified water, and a preservative—no fillers or artificial additives. The metered spray mechanism delivers consistent 10 mg doses, allowing you to dial in between one and four sprays per day.

Users transitioning from NAD+ injections report that the spray provides a moderate energy lift without the cost or inconvenience of IV therapy. Multiple users noted a gradual improvement in energy and mental clarity around day seven of consistent use. The 10 mg concentration means two sprays deliver 20 mg total, which some users find comparable to a low-dose sublingual or oral precursor supplement.

A subset of users reports nasal burning or throat drip, particularly at higher doses. Starting with one spray per day and increasing slowly seems to reduce this reaction. Some customers felt the 10 mg spray was less effective than subcutaneous NAD+ injections, though they acknowledged the spray is far more convenient and affordable for daily maintenance.

The 5 mg per spray version from Bulk Essentials offers the same clean formulation as its 10 mg sibling but at half the per-spray potency. This is the sensible starting point for anyone new to NAD+ nasal sprays. At 5 mg per spray, you can start with one spray and build to four sprays per day (20 mg total) without overwhelming your nasal mucosa.

Users who found the 10 mg version too harsh on their sinuses had better results with this lower concentration. Several reviews mention a gradual increase in calm, focused energy that becomes noticeable around day seven, with no jittery side effects. The bottle delivers 100 sprays, and with a starting dose of one to two sprays per day, a single bottle lasts 25 to 50 days.

Some users who previously used NAD+ injections found the spray less powerful, but they appreciated the convenience and lower cost for daily maintenance. A few users experienced throat burning even at 5 mg per spray, suggesting individual sensitivity varies significantly. Buying the smaller size first is a smart strategy to test tolerance before committing to the higher concentration.

Codeage’s standard liposomal NAD+ capsule delivers the same 500 mg of NAD+ per serving as their Ultra formula but without the resveratrol, quercetin, and B vitamins. This stripped-down approach is ideal for users who already take those cofactors separately or want a pure NAD+ liposomal option. The phospholipid complex uses non-GMO sunflower oil, and the capsules are vegan, gluten-free, and soy-free.

Users report noticeable improvements in skin texture, with one reviewer specifically mentioning reduced crow’s feet and fine lines after two weeks. Another user in their 60s bought it for their parents, who reported feeling noticeably healthier and requested six additional bottles. The formula includes betaine anhydrous (trimethylglycine) to support the methylation cycle that recycles homocysteine back to methionine.

One review flagged the price as high for a monthly supply, and some users may prefer the added cofactors in the Ultra version for a similar bottle cost. The 60-capsule bottle provides one month of supply at two capsules per day, making it a solid option for those who want liposomal NAD+ without extras.

Pure Encapsulations uses NIAGEN nicotinamide riboside, a well-studied NAD+ precursor, combined with 150 mg of trans-resveratrol and 800 mcg of sulforaphane per serving. This is not active NAD+ but a precursor that your body converts into NAD+ through a multi-step salvage pathway. The inclusion of sulforaphane adds Nrf2 activation, supporting antioxidant gene expression alongside NAD+ replenishment.

The 2-capsule serving size yields 300 mg of NR, which is a moderate dose compared to some dedicated NR supplements. Users report gradual energy improvements over weeks rather than immediate jolts, with several mentioning they notice the difference if they miss a day. The formula is hypoallergenic, gluten-free, and non-GMO, aligning with Pure Encapsulations’ reputation for clean manufacturing.

A few users note the capsules are larger than average, which may be difficult for some to swallow. The cost per month is higher than some NMN or NAD+ spray options, but the brand’s rigorous third-party testing and quality sourcing justify the premium for users who prioritize purity over maximum dosage.

Quicksilver Scientific takes a different route with their NAD+ Gold+ formula: it delivers nicotinamide mononucleotide (NMN) instead of NAD+ itself, trusting the body’s conversion enzymes to produce NAD+ from the precursor. Each pump provides 50 mg of NMN and 50 mg of TMG (trimethylglycine) in a proprietary liposomal suspension designed for rapid sublingual and mucosal absorption. The formula requires refrigeration and ships cold to preserve the liposomal integrity.

Users consistently report this product outperforms capsule-based NAD+ supplements by a wide margin. One reviewer noted that five times the dose in capsules was needed to feel the same effect as a single pump of this liquid. Another user managing bipolar disorder found it helpful for recovery from manic episodes without destabilizing their mood. The liposomal delivery system appears to bypass the first-pass metabolism that degrades oral NAD+ precursors.

The 50 mL bottle provides roughly 30 servings at the recommended dose. Some users find the taste mildly unpleasant, and the need for refrigeration reduces portability. A few reviews mention that the effects feel stronger than expected, so starting with a half-pump is advisable for first-time users.

The Dart Nasal Atomization Device is not a supplement—it is a medical-grade atomizer that turns liquid solutions into a fine mist for nasal delivery. For users who source NAD+ in bulk liquid powder form or want to use their own compounded NAD+ solution, this device provides precise, controlled atomization. It attaches to standard oral syringes and delivers medication in a fine spray that coats the nasal mucosa evenly for absorption.

Users in the veterinary space have praised this device for intranasal medication delivery to dogs and cats, but it works equally well for human use. The atomizer eliminates the need for IV access while still providing rapid uptake through the nasal cavity. Each case contains 25 individual atomizers, making this a disposable option for users who rotate through multiple solutions.

The device is designed for single-patient use. While some users clean and reuse them, the manufacturer recommends disposal after each use to prevent contamination. This is an advanced option for users who want complete control over their NAD+ dosage and delivery method, but it requires sourcing and preparing your own NAD+ solution.
