Tips and expert advice on supplements and wellbeing

Most of us think of “omega-3” as a single nutrient — something you get from a fish-oil capsule or a piece of salmon. In reality, the two fatty acids behind omega-3's reputation, EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), behave less like interchangeable teammates and more like two specialists with entirely different jobs. Understanding that difference changes how we think about dosing, product formulation, and what a given “omega-3 benefit” is actually coming from.

Most antioxidants stop at the door to your brain. NAC has a keycard. Here's what that actually means in practice.

Detox supplements love big promises. Here's what NAC can honestly claim about heavy metals — and where the evidence runs out.

Your cells run on a molecule called NAD+. It picks up energy and turns into NADH — then has to switch back into NAD+ before it can be used again. Sometimes energy problems happen because that switch-back gets stuck. Other times, NAD+ just gets used up and doesn't come back. Same tiredness. Two very different reasons.

Your mitochondria aren't broke. They're just not getting the memo. Think of your mitochondria like a power plant. It doesn't start generating electricity just because there's fuel sitting in the warehouse — it starts working when it sees a stack of "drained batteries" waiting to be recharged. That stack of drained batteries is the real signal your body sends when it needs more energy. When that signal shows up quickly and steadily, the power plant hums along just fine. But in a system under...

Everyone files NAC under 'antioxidant supplement' and stops reading — which means almost everyone misses its more interesting job. N-acetylcysteine's reputation begins and ends with antioxidant support for most people. But cysteine, the amino acid NAC delivers, sits at a metabolic crossroads that extends well beyond glutathione synthesis.

NAD+ has become the trendy word in the energy and longevity world — more NAD+, more energy, more everything good. But that only works if the road NAD+ is traveling on is actually open. If there's a jam further down the highway, sending more cars onto it doesn't get anyone anywhere. It just makes the jam bigger.

Right now, your body is making a molecule that helps build the brain chemicals behind a good mood. Some people take more of it and feel a real lift. Others take the exact same pill and feel nothing. This is the simple reason why.

Methylene blue is a laboratory-produced dye that also has specific applications in medicine. It was first synthesised in the 19th century and later became one of the earliest synthetic substances used medicinally.

Your metabolism runs an engine with one exposed part that rusts quietly for years, and almost nobody protects it on purpose. Think of your metabolism like an engine built to burn through fuel smoothly, step by step, all day long. Deep inside that engine is one small part that is especially exposed. It is the very first step where fuel gets handed off into the cycle that produces cellular energy. That part has a weakness: it is unusually sensitive to everyday oxidative wear, the kind that...

You could drink a gallon of water before training and still walk away dehydrated. You could also buy the "premium" electrolyte tub next to it and still just be drinking salted water with a marketing budget. There’s only one formula on the shelf built to fix both problems at once.

Your mitochondria can have perfect fuel, perfect oxygen, and still misfire, because of a single mistranslated instruction. Most conversations about mitochondrial support focus on fuel and cofactors, what goes into the system. Taurine works at a different level entirely: it affects how the genetic instructions for building the system get read in the first place.
