What Our Customers Say

Have been taking for 6 weeks with positive results. Recommended.

After about 4 weeks I started noticing a difference. Happy with the product.

Natto-derived MK-7 is the most bioavailable form. This product specifies the source clearly. Good quality.

The tingling is manageable and the benefit during high-rep sets is real. More reps before failure on leg day.

Do not expect immediate results. After 3 weeks my mood baseline is notably higher and I fall asleep more easily.

Really good quality product. Only minor thing is the capsules are quite large but you get used to it. Has definitely been working for me over the past 13 weeks.

I trust Medibro because they are transparent about what is in their products and actually dose things correctly. So many brands underdose, not this one. Proper amounts that match the science.

Do not expect overnight results. Like any quality supplement, you need to be consistent. After 4 weeks I have noticed clear benefits. Sticking with it.

Been using for 4 weeks. Definitely contributing to skin clarity. No unpleasant effects and the price is fair. Good brand overall.

I cycle through different proteins to avoid flavour fatigue. This chocolate whey isolate is genuinely the best-tasting I've come across. The quality is clearly high — no fillers, clean ingredient list.

No jitters, no crash, just clean sustained focus for 4–5 hours. The theanine really does smooth out the caffeine effects. I use this before any mentally demanding work.

I'm 58 and had been experiencing increasing knee pain, particularly on stairs. Six weeks on this formula and the improvement is dramatic. I can climb stairs without wincing and my morning stiffness is gone.

My nutritionist recommended 5g twice daily for gut wall integrity. After 6 weeks my IBS symptoms are significantly calmer.

Most supplements are taken morning but cortisol is also elevated in the evening for stressed people. This evening timing makes scientific sense. Sleep is noticeably deeper within 2 weeks.

Been taking this for 6 weeks alongside a good sleep routine. The combination of 5-HTP and B6 is well-established — B6 is the cofactor for serotonin synthesis. I sleep better and feel more positive in the mornings. Not a miracle but a real, noticeable shift.

30mg of highly bioavailable zinc is meaningful supplementation. My zinc levels have normalised and I feel better.

The MK-7 form has a 24-72 hour half-life versus hours for MK-4. One daily dose is adequate with MK-7. Good product.

K2 directs calcium away from arteries. With the amount of calcium we absorb from diet and D3 supplementation, K2 is essential insurance.

After 8 weeks I can genuinely see a difference in my skin hydration. Lines around my eyes look less pronounced.

I take this alongside glucosamine and my knee clicking has reduced significantly. Not sure which one is doing the work but I'll take it.
