Female Fiks · 30–49
You're exhausted but it's not just sleep. We know why. We fixed it.
The tiredness that coffee doesn't touch, the brain fog, the hot flashes, the mood swings, your body is changing and you're tired of not understanding why.
Your story.
You're running on fumes. Work is demanding, family needs things, and your body is betraying you in ways you didn't expect. You used to have energy. You used to bounce back. Now everything takes longer and you're tired all the time.
Here's what's actually happening: this isn't aging, this is your body missing something. The exhaustion isn't laziness, it's a nutrient gap that's fixable. The brain fog isn't dementia, it's specific and addressable. Your body isn't betraying you, it's just asking for what it needs.
We spoke with thousands of women like you: short on time, hard to build habits, overwhelmed by choice, tired of trying things that don't work. So we did the research, built one sachet with exactly what your body needs at this stage, and made it one decision, done. So you can focus on living, not on figuring out your health.
What's in it, and why.
Vitamin D3 1000IU
Universal deficiency, worse at Scottish latitude
NDNS shows Vitamin D deficiency is near-universal across adult cohorts, worse in Scotland.
Magnesium Bisglycinate 300mg
Sleep, stress, and mood
Around 1 in 5 women 30–49 fall short of the magnesium reference intake in NDNS; it supports sleep, mood and stress.
Iodine
Energy and thyroid function
NDNS shows iodine shortfalls persist through this decade, and thyroid output drives day-to-day energy.
Methyl Folate
Cognitive function and mood
Folate intakes stay well below the recommended threshold for most women this age per NDNS.
CoQ10
Energy and cardiovascular health
Not an NDNS nutrient, but the body's own CoQ10 production drops from the mid-30s, so we top it up.
Omega-3 (triglyceride form)
Recovery and inflammation
NDNS shows most UK adults eat under half the recommended oily fish intake, so EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) run low.
About 1 in 5 UK women lack magnesium, perimenopause symptoms are real and fixable, and your body needs specific support at this stage of life. We researched the data, then built to the data.
What you'll get from your Fiks.
Real sleep, not just hours in bed. Energy that coffee alone can't give you. A clearer head when brain fog hits. Heart and cellular support for the decade ahead.
The habit.
One sachet every morning, that's 10 seconds, that's your entire routine. Not another thing to remember, not another complicated supplement schedule, just one moment for yourself that gives you back your energy, your focus, your peace. Real sleep, real energy, real you again.
