Have questions?
What does Magnesium+ actually do?
A premium blend of three bioavailable magnesium forms, enhanced with Vitamin B6 and Ashwagandha. Supports energy, muscle recovery, relaxation, and sleep quality.
When should I take it?
Whenever it suits your routine. Two capsules during the day support energy and focus; two before bed support muscle recovery and sleep. What matters most is taking it consistently.
Will I feel a difference right away?
Some people notice calmer evenings within the first week. Magnesium works by topping up a shortfall, so the fuller benefits — recovery, sleep quality, resilience under load — build over a few weeks of daily use.
Can I take it every night?
Yes. Magnesium+ is a daily blend designed for continuous use, and 90 capsules is 45 servings — a month and a half at two capsules a day.
Are the supplements safe and tested?
Manufactured in the UK by Bio-Synergy Ltd under UK food supplement standards, with full traceability from ingredient to shelf and independent testing.
Can I take it with other medications or supplements?
Magnesium+ is a food supplement, not a medicine. If you take prescription medication, are pregnant or breastfeeding, or have a medical condition, check with your doctor or pharmacist before starting.
Do they have any side effects?
The three forms used here — Bisglycinate, Malate and Citrate — are chosen partly because they are gentle on digestion, unlike the oxide found in cheaper supplements. Do not exceed the stated dose.
Is it suitable for vegans?
Yes. Magnesium+ is vegan-friendly.
What if it doesn't work for me?
Return it within 30 days for a full refund. No questions, no hoops.
How long does delivery take?
UK orders are typically delivered within 2-3 working days, and shipping is free on orders over £35.
