An essential mineral that supports a balanced mood, hormonal health and everyday immune defence.

Everyday mood

Questions, answered

How quickly will I feel it?+
Many people feel calmer and less on-edge within the first week or two. Magnesium works best topped up daily, so give it a consistent 2–4 weeks for the full effect on mood, tension and sleep.
Will it make me drowsy?+
No. SL8 isn’t a sedative — it gently supports your body’s own calm, so you can take it day or night and feel settled, not groggy.
When should I take it?+
Two capsules a day with water, whenever suits you. Many like it in the evening to help wind down.
How does the subscription work?+
Your bottle ships monthly at the discounted price. Skip, pause or cancel anytime from your account — no lock-in. New subscriptions include both free welcome gifts.
When will it arrive?+
Most orders arrive within 3–7 business days with free shipping, and you’ll get tracking as soon as it ships.
