Frequently Asked Questions
What are energy supplements?
Energy supplements are vitamins, minerals and botanicals that support your body's own energy production, rather than stimulants that artificially perk you up. The core players are the B vitamins, which contribute to normal energy-yielding metabolism, alongside minerals like iron and magnesium, and compounds such as Coenzyme Q10 - the 'biochemical spark plug' found in nearly every cell.
What are energy supplements good for?
They keep the machinery that converts food into energy properly supplied. Vitamin B12 contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue, iron supports normal formation of red blood cells that carry oxygen around the body, and magnesium contributes to both energy metabolism and normal psychological function. If you're regularly flagging by mid-afternoon, these are the nutrients worth checking first.
Which energy supplement is right for me?
Start with the likely gap. For everyday tiredness, Vitamin B12 Sublingual 1000mcg is the most popular choice - it dissolves under the tongue for direct absorption - while Super B-50 Complex covers all eight B vitamins with time-release absorption through the day. Women during their monthly cycle often reach for stomach-friendly Iron 14mg, and from the 50s onwards, Ubiquinol - the premium form of CoQ10 - is the one to consider, as our natural CoQ10 levels decline with age.
Do energy supplements work like caffeine?
No - and that's the point. Caffeine borrows energy by stimulating your nervous system; energy nutrients help your body make its own, by supporting normal energy-yielding metabolism. That means no jitters, no afternoon crash and nothing to interfere with your sleep - in fact they pair sensibly with our sleep range, since good energy starts with good rest.
Why am I always tired?
Often it's the everyday suspects - poor sleep, stress, a hurried diet - but persistent tiredness can also point to a nutritional shortfall. Low iron and low vitamin B12 are two of the most common, which is why both contribute to the reduction of tiredness and fatigue. A good multivitamin covers the basics; if tiredness persists despite decent sleep and diet, see your GP, as it can have causes a supplement won't fix.
What is CoQ10 and why is it linked to energy?
Coenzyme Q10 is a vitamin-like compound found in nearly every cell, where it's essential to energy production - it's most concentrated in hard-working organs like the heart. Levels naturally decline as we age, which is why CoQ10 120mg + B1 and one of the UK's strongest 300mg formulas are so popular with those in their 50s and beyond.
Which vitamins help with tiredness and fatigue?
The B family leads the way - B12, B6, riboflavin, niacin and pantothenic acid all contribute to the reduction of tiredness and fatigue - alongside vitamin C, magnesium, iron and folate. Rather than juggling them separately, Vitamin B Complex Extra provides high levels of all eight B vitamins in one tablet, ideal for long-term daily use.
When should I take energy supplements?
Morning, with breakfast - that way the nutrients support your metabolism through the day, and some people find B vitamins a little too lively near bedtime. Because B vitamins are water-soluble and can't be stored, daily consistency matters far more than perfect timing; our time-release B-50 spreads absorption across the day for good measure.
Can low iodine or thyroid function affect energy?
It's an overlooked one - iodine supports normal thyroid function, and your thyroid effectively sets the body's metabolic pace. Iodine also contributes to normal energy-yielding metabolism, and intakes can run low if fish and dairy rarely feature in your diet. Our Sea Kelp Extract provides 100% NRV of iodine per tablet from a natural marine source.
