Female Fiks · 16–29
You want energy that lasts. Clarity that's real. We built that.
That 3pm crash is real, the brain fog is real, and the wanting to invest in yourself but never quite getting around to it, that's real too. We understand, we researched it, and we fixed it.
Your story.
You're juggling work, life, fitness, social, everything. You care about how you look and feel. You've tried skincare routines, supplements, wellness trends, nothing ever seems to stick or work as well as promised. Here's the truth: your body's just missing some key things. Energy crashes happen because you run out of fuel mid-day. Brain fog isn't normal, it's fixable. Mood swings aren't character flaws, they're nutrients.
The problem isn't willpower. It's habit. Building habits is hard when you're short on time and overwhelmed by choice. So we removed all of that. One sachet every morning, that's your habit, done.
What's in it, and why.
Vitamin D3 1000IU
Universal deficiency, worse at Scottish latitude
NDNS shows 18–31% of adults are deficient, higher in Scotland; D3 raises serum 25-hydroxyvitamin D (25(OH)D3), the standard blood marker for vitamin D status, most effectively.
Iodine (potassium iodide)
Energy and thyroid function
NDNS shows iodine intake in this group has fallen sharply since 2013, and it drives thyroid and energy function.
Methyl Folate
Mood and energy
NDNS puts around 83% of women this age below the recommended folate threshold; the methylated form absorbs better.
Iron Bisglycinate
Energy and recovery
25.3% of women aged 20–59 fall below the iron reference intake (Derbyshire, Frontiers in Nutrition, 2018), often linked to menstrual losses.
Magnesium Bisglycinate
Sleep and stress
About 1 in 5 women this age are below the magnesium reference intake per NDNS, which shows up as poor sleep and stress tolerance.
Selenium
Immunity and clarity
UK selenium intakes sit below reference levels across most adult groups in NDNS, and it underpins immune function.
Why these specific nutrients? Because research shows you're missing them. We saw a 29% decline in iodine intake among women of childbearing age between 2013 and 2023, 83% of women your age are below optimal folate, and 25.3% of women aged 20–59 are iron deficient. We didn't guess, we researched, and then we built exactly what the data said you need.
What you'll get from your Fiks.
Lasting energy that gets you past the 3pm crash. A steadier mood. Support for skin from the inside, not just skincare on top. Iron and iodine working together so you're not running on empty.
The habit.
One sachet every morning. That's it. No bottles to forget, no guessing, no failing. It arrives, it sits on your shelf, and every morning one sachet becomes the easiest investment you'll make in yourself. Energy that holds through the day, sleep that actually helps, a mind that works. Because your body gets what it actually needs.
