Cautions & interactions

- Contains beta-carotene (in the multivitamin): not suitable for smokers or people exposed to asbestos.
- Contains vitamin K. If you take anticoagulant medicine such as warfarin, speak to your GP or pharmacist before taking these products.

A GP’s View on Supplement Timelines
Consistent Daily Use: What Happens in the Body
Many supplement brands print fixed charts promising you will “feel more energy in Week 2” or “see thicker hair in Month 2”. As practising UK GPs, we won’t do that. What happens when you take a supplement depends on whether you are topping up an everyday diet (where nutrients work quietly in the background and you may not “feel” a sudden change) or correcting a low level found on a GP blood test.
Days 1–7
Daily routine & digestive comfort
Take 1 capsule a day with a main meal and water. Taking your capsule with food is gentler on the stomach and helps fat-soluble vitamins absorb normally.
Weeks 2–6
Steady daily nutritional intake
Consistent daily intake helps top up your diet every day rather than in sporadic bursts. Water-soluble nutrients (such as B vitamins and vitamin C) are used daily and aren’t stored in large amounts, while fat-soluble nutrients (such as vitamin D) build up gradually with steady daily intake.
Weeks 8–12 (1–2 pouches)
Long-term maintenance & GP blood re-checks
Red blood cells turn over roughly every 90 to 120 days. When a GP treats a confirmed low level (such as vitamin B12 or vitamin D), NICE and NHS guidance typically schedules a clinical review or follow-up check around 3 months. For everyday dietary top-ups, steady ongoing habits matter most.
