For Magnesium Glycinate many customers notice improved sleep quality within 1-2 weeks. For Vitamin D3 meaningful changes in energy and mood typically take 4-6 weeks as your body rebuilds its stores. Supplements work by correcting deficiencies over time rather than producing immediate effects.

Yes — and they actually work better together. Magnesium is required for your body to convert and activate Vitamin D3. Many people take D3 without realising their low magnesium levels are limiting its effectiveness. Taking both together is not just safe — it is the smarter approach.

Most supermarket magnesium supplements use magnesium oxide which has an absorption rate of around 4%. Our Magnesium Glycinate absorbs at over 80%. The difference is not marketing — it is the biochemistry of the two forms. We also include four additional active ingredients: Ashwagandha Root Extract standardised to 5% withanolides, L-Theanine, Zinc Gluconate, and Pyridoxal-5-Phosphate — the active form of B6.

Vitamin D is fat-soluble — it cannot be properly absorbed without fat present. Most D3 supplements use dry powder in a capsule which significantly limits absorption. Our D3 is suspended in olive oil which mirrors how your body naturally absorbs vitamin D from food, giving you the full benefit of every dose.

Directions for use vary by product. Please refer to the label on your product packaging or the product page on our website for full usage instructions specific to your supplement. As a general rule, food supplements work best when taken consistently at the same time each day, ideally with a meal.
