Frequently asked questions

We make a range of healthy ageing supplements, all formulated and encapsulated in New Zealand:

• NMN capsules (60 and 180 count, 300mg per capsule)
• NMN powder (100g)
• NR (Nicotinamide Riboside), 60 count, 300mg per capsule
• Spermidine capsules (2mg)
• L-Ergothioneine + PQQ capsules
• CA-AKG (Calcium Alpha-Ketoglutarate) capsules
• TMG (Trimethylglycine) capsules
• GlyNAC (Glycine + NAC) capsules
• Trans-Resveratrol capsules
• Hyaluronic Acid with Micro Vitamins

Our capsules are plant-based HPMC (vegetable cellulose), not gelatine, and the formulations contain no animal-derived ingredients — except for our Hyaluronic+ with low-dose micro vitamins, which is vegetarian but not vegan.

All but one of our products contain no gluten, dairy, soy, nuts or egg. The one exception is Spermidine, which is derived from wheat germ extract and contains small amounts of gluten.

This mostly comes down to preference. Capsules are no-fuss, pre-measured and convenient. Powder is more economical per gram and lets you adjust your serving size.

Both are forms of vitamin B3 that the body can use to make NAD+, and both have been shown in human studies to raise blood NAD+ levels. They take slightly different routes to get there, and there is ongoing scientific debate about which is more effective, without a clear winner in human research so far. NMN is our core product and the one most of our customers choose. Some people prefer NR or alternate between the two. If you’d like to go deeper, our Science page and articles cover the research in more detail.

Yes — every bottle has a best-before date on the label or bottom of the bottle. Our NMN and NR are stabilised forms with a room-temperature shelf life of more than three years. We keep our own stock in a cool room and recommend you store all our products in a cool, dry place out of direct sunlight, with the lid on tight. Refrigeration is not necessary.

No. Our products are dietary supplements, not medicines. They are not intended to diagnose, treat, cure or prevent any disease. What we sell is based on published research into the ingredients, and we do our best to explain that research plainly, including where it is still early or preliminary.

The serving size on each label is our recommended starting point (for example, two 300mg NMN capsules per day, or two GlyNAC capsules per day). Many customers take NMN in the morning, as it’s often described as supporting energy, but there is no strong evidence that timing matters much. Some customers choose to take more than the label serving, following published protocols such as 1,000mg of NMN per day. That is a personal decision, and we’d suggest discussing it with your doctor, especially if you have any health conditions.

Many of our customers do. NMN and TMG are a common pairing, as are NMN and Trans-Resveratrol, and we offer bundles built around these combinations. The ingredients are generally well tolerated together, but we are not clinicians. If you’re taking a number of supplements, or anything else alongside them, it’s worth running the combination past your GP or a registered nutritionist.

It varies a lot, and some people don’t notice a subjective change at all — which doesn’t necessarily mean nothing is happening. Blood NAD+ levels have been shown to rise within a few weeks of daily NMN or NR in human studies. In terms of how you feel, customers who report a difference most often mention it after three to four weeks of consistent daily use. A common bit of feedback we get is that people notice it when they stop taking it and go back to how they used to feel.

Please talk to your doctor or pharmacist first. We don’t give medical advice, and the safety of these ingredients during pregnancy and breastfeeding has not been established in research, so we don’t recommend them in those situations. If you take prescription medication — particularly anything affecting blood sugar, blood pressure, liver function or blood clotting — check with your doctor before adding a supplement.

Our products are generally well tolerated at the suggested label serving size. Some people report initial mild digestive discomfort with GlyNAC, particularly on an empty stomach, which usually settles by taking it with food or reducing the amount for a week or two. If you experience anything that concerns you, stop taking the product and speak to your doctor.

All our products are formulated, encapsulated and bottled in New Zealand at GMP-certified facilities in Hamilton and Christchurch.

Yes. Our NMN and other key products are tested by independent laboratories in the USA and Australia for purity, authenticity and heavy metals, and the certificates of analysis are on each product page.
