Alongside vitamins and minerals, the range includes Essensey Korean Ginseng, Trec Ashwagandha Ultra, Trace Minerals Shilajit 1000 mg capsules, Ultra Lyte Shilajit resin and Snap Energy & Metabolism. These botanicals have no authorised health claims, so judge them on their ingredient panels and check for caffeine or other stimulants before taking them later in the day.
Persistent tiredness has many possible causes. If it lasts for weeks, a GP blood test can show whether a nutrient such as iron or B12 is genuinely low before you choose a supplement.
Energy & Fatigue: your questions answered
Which vitamin should I choose for tiredness?
Several nutrients carry the authorised claim of contributing to the reduction of tiredness and fatigue, including vitamin B12, iron, magnesium and vitamin C. The right one depends on your diet: B12 is the usual gap on a plant-based diet, while iron matters if your intake is low. A GP blood test is the best guide.
What is the difference between methylcobalamin and cyanocobalamin?
Both are forms of vitamin B12 and carry the same authorised claims. Methylcobalamin is a naturally occurring form; our NOW lozenges provide 1000 mcg and the OstroVit tablets 100 μg per serving.
Can I take B12 and iron together?
Yes, they are commonly taken together, and Snap Iron Builder already combines iron with B vitamins and vitamin C. Vitamin C increases iron absorption, and taking iron with food helps if it upsets your stomach.
Is shilajit an energy supplement?
Shilajit is a mineral-rich resin with a long traditional use, but it has no authorised health claim in the UK. We stock it as capsules and as a resin; follow the label serving.
Do energy formulas contain caffeine?
Some do. Check the ingredient panel for caffeine, guarana or green tea extract, and take stimulant formulas earlier in the day.
