Cellular energy labels love long stories. The useful information is usually two centimetres of panel. If you can read NR and TMG lines confidently, you can ignore most of the surrounding mythology.
This is a worked method using RevaHealth NAD+ Precursor Complex: 300 mg nicotinamide riboside chloride and 300 mg TMG per one-capsule serving.

Line one: nicotinamide riboside
Find whether the label says nicotinamide riboside, NR, or a branded NR ingredient. Find the milligrams per daily serving. Confirm whether that number is for one capsule or a multi-capsule serving.
Our panel states nicotinamide riboside chloride at 300 mg in a one-capsule serving. That is your baseline comparison figure.
If a competitor lists “NAD+ complex 500 mg” without saying how much is NR, you do not have a comparable line yet.
Line two: TMG / betaine
TMG may be labelled trimethylglycine or betaine anhydrous. Match names, then match milligrams per day. Our formula uses 300 mg.
Some products omit a methyl donor entirely. That is a formulation choice, not automatically a flaw — but it is a difference you should see rather than assume.
Do not accept “matrix includes methyl support” without amounts.
Branded ingredients and what they change
Trade names can indicate a particular manufacturing source. They should appear alongside the compound name, not instead of it. Licence fees may raise price; they do not excuse hiding milligrams.
Compare branded NR at 100 mg with non-branded NR at 300 mg carefully. Story versus amount is the perpetual trap in this aisle.
Ask for the compound first, the trademark second.

Cost discipline for expensive capsules
Divide pack price by daily servings. At £38.99 for sixty one-capsule servings, NAD+ Precursor Complex is about 65p per day before any subscription discount. A cheaper bottle with a three-capsule serving can cost more per day.
Cost per gram of NR is an optional nerd layer after servings match.
If the daily cost hurts, that is data. Longevity spending should be conscious.
Cautions and suitability
Read who should seek advice before use. If you take medicines or have a relevant condition, ask a pharmacist. Do not treat online longevity forums as your clinical team.
Stacking multiple B3-related products can be pointless or unwise. Check your multi for niacin forms too.
Stop and seek advice if something feels wrong after starting a new product.
A two-product bake-off worksheet
For product A and B write: NR mg/day, TMG mg/day, capsules/day, cost/day, storage, cautions, and whether blends hide anything. Circle unknowns. Unknowns count against a product.
Buy the clearer panel when amounts are similar. Clarity is part of quality.
If both panels are opaque, walk away from the category until a better label appears.
Hydrates, chlorides and name variants
Ingredient chemistry naming can include salt forms and hydrates. Compare like with like as far as the label allows, and be suspicious when a brand refuses to state the compound clearly.
If two products both say NR but only one states the salt form and milligrams plainly, prefer the plain speaker.
Laboratory certificates should match the batch when brands lean on testing theatre.
Stacking NR with multis and flush niacin
Check whether your multi already contributes meaningful nicotinamide or nicotinic acid. Unnecessary overlap is common in people who buy every B-vitamin story they hear.
Flushing from nicotinic acid is a different experience than NR for many users; still, total B3-related intake is worth a second look with a professional if you stack aggressively.
Simplifying to one clear product is allowed.
What to ignore on longevity product pages
Countdown timers, free gifts that force larger packs, and celebrity immortalisation quotes. Also ignore graphs with no axes that mean anything.
Look for serving size, milligrams, cautions, and a company willing to discuss limits.
That shopping style protects both wallet and expectations.
Third-party testing without theatre
Ask whether a certificate of analysis matches your batch number. A generic PDF from two years ago is decoration.
Heavy-metal and identity testing are meaningful when current. Lifestyle badges without data are not.
Prefer brands that answer batch questions without hostility.
Importing foreign NMN while NR is on the shelf
People sometimes import NMN while a transparent NR product is available domestically. That can create customs and novel-food complications.
Our NMN hold is deliberate; overseas cart links are not a regulatory opinion.
If you choose NR, read the NR line on its own merits.
How to use this guide with our formulas
RevaHealth publishes these journal guides so you can judge labels with less noise. Where a product is named, it is a worked example of composition and serving arithmetic, not a promise that the formula will deliver a medical outcome for you.
Authorised UK health claims, where they appear on labels, are narrower than social media language. For probiotic, prebiotic and postbiotic ingredients there are no authorised health claims of the kind shoppers often expect. For nutrients such as vitamin D, claim language is tied to conditions of use and still does not license disease-treatment stories.
Before you add any bottle — including ours — add up overlapping nutrients across your routine, read the caution panel in full, and ask a pharmacist when medicines, pregnancy, breastfeeding, planned surgery or a diagnosed condition are part of your picture. Food supplements do not replace a varied diet, sleep, movement or clinical care.
If a guide changes how you shop, that is success even if you buy nothing today. Clarity is the product of this journal; capsules remain optional tools for people who have already decided a specific compositional job needs doing.
Frequently asked questions
Is 300 mg NR a standard dose?
There is no authorised recommended intake like vitamins with NRVs. Trial amounts vary. We publish what is in the capsule; we do not prescribe a clinical protocol.
Can I open the capsule?
Follow labeled directions. Altering dosage forms can change how you experience a product and may conflict with how it was designed to be taken.
Does TMG need to equal NR milligram for milligram?
Not by law or universal science consensus. Our 1:1 mg pairing is a transparent formulation choice, not a universal rule.
Should I cycle NR?
Internet protocols vary. There is no UK label requirement to cycle. If you are considering complex protocols, involve a qualified professional.
Before choosing a supplement
- Read the complete current label, including the active and the other ingredients.
- Compare the daily serving rather than the number printed on the front of the bottle.
- Add up every source of the same nutrient across your whole routine.
- Ask a pharmacist or qualified healthcare professional about medicines, pregnancy, breastfeeding, surgery or an existing condition.
- Remember that food supplements do not replace a varied, balanced diet and a healthy lifestyle.
