Shilajit benefits: what it is and how to take itShilajit is a dark resin that seeps from mountain rock, rich in fulvic acid and minerals. It has been used in Ayurveda for centuries to support vitality and energy. Small human trials suggest possible effects on men's hormone levels, but evidence is limited. Raw shilajit can contain heavy metals, so only use purified, tested products.2 October 2026 · Read 
EnergyNAD vs NMN: what is the difference?NAD+ is a coenzyme found in every cell and used in energy production and cell repair. NMN is a smaller molecule the body converts into NAD+. Human trials show NMN supplements can raise blood NAD+ levels, but evidence for wider benefits is limited. Research on taking NAD+ itself by mouth is even more limited.
EnergyWhat is Modern Noise? The daily drain on your energyModern Noise is Nutra Formulations' name for the everyday drag of stress, short sleep, ultra-processed food, inactivity and late-night screens. Each drain is small, but together they can leave you tired and unfocused. The answer starts with habits: regular sleep, fewer bedtime screens, real food and daily movement, with supplements as support.
EnergyMagnesium glycinate vs citrate: which should you take?Magnesium glycinate and citrate are both well-absorbed organic forms. Glycinate is usually gentler on digestion and has the more relevant sleep research, while citrate has the strongest direct absorption data but is more likely to loosen stools. Most adults need 270 to 300 mg of magnesium a day in total.
EnergyHow much magnesium glycinate should you take?Most adults need 270 to 300 mg of magnesium a day from all sources, and the NHS says 400 mg a day or less from supplements is unlikely to cause harm. Recent trials of magnesium glycinate used around 250 mg of elemental magnesium daily. Always check the label for elemental magnesium.
EnergyCoenzyme Q10 benefits: what it does and who might need itCoenzyme Q10 is a compound your body makes to help cells produce energy, and it also works as an antioxidant. Levels tend to fall with age, and statins can lower blood levels. Research on supplements for statin-related muscle aches and heart failure is mixed, so it suits some people more than others.
EnergyBest energy supplements: what works, and what to avoidThe best energy supplements are those that fill a real gap. B vitamins, iron, magnesium and vitamin C all contribute to the reduction of tiredness and fatigue, and they help most when your diet falls short. Avoid high-caffeine blends and unneeded iron, and see your GP if tiredness lasts for weeks.
EnergyVitamin B12 side effects, benefits and dosageVitamin B12 rarely causes side effects. The NHS says adults need about 1.5 micrograms a day and that taking 2 mg or less a day from supplements is unlikely to cause harm. Rare skin reactions have been reported, mostly with high-dose injections. Some medicines, including metformin and acid-reducing tablets, can lower B12 levels.
