DOUBLE WOOD

Double Wood is a supplement brand built around single-ingredient formulas, giving you a straightforward way to choose the exact form you're looking for without unnecessary additions. NexusCare stocks a focused range of Double Wood products covering different types of magnesium alongside NAD+ and berberine formulas, all designed for people who prefer to select their supplements by ingredient and format rather than by blend.

A buying guide to the Double Wood range

Magnesium is the largest part of this collection, and Double Wood offers it in several forms. The Double Wood Magnesium Citrate Supplement is one of the most common and widely used forms of magnesium. The Double Wood Magnesium Glycinate Supplement pairs magnesium with glycine, while the Double Wood Magnesium Malate Supplement combines magnesium with malic acid. For those specifically looking for the patented Magtein form, the Double Wood Magnesium L-Threonate (Magtein) Supplement is also part of the range. Beyond magnesium, the collection includes the Double Wood NAD+ Supplement and the Double Wood Berberine Supplement, each formulated around a single named ingredient.

If you're comparing magnesium forms across brands, our broader Magnesium collection lets you see how Double Wood's options sit alongside other manufacturers. For a wider view of what else NexusCare carries in this space, the Supplements and Vitamins collection and the general Health category are useful starting points too.

Choosing the right Double Wood formula

Because each Double Wood product centres on a single active ingredient, the main decision is simply which form suits your routine. Magnesium citrate, glycinate, malate and L-threonate are chemically different compounds attached to magnesium, and people often have a personal preference for one form's texture, capsule size, or how it fits into an existing supplement stack — the product label for each item will list the specific format and capsule count. NAD+ and berberine are structurally unrelated to magnesium and to each other, so if you're unsure which ingredient is relevant to your goals, it's worth reading the product page carefully and checking with a pharmacist before adding anything new to your routine.

Always read the label in full before use, note any other supplements or medications you're taking, and speak with a healthcare professional if you have questions about how a particular ingredient might fit your circumstances. NexusCare's pharmacist team is available to help you compare the different Double Wood formats if you're unsure which one to pick.
