BEFORE YOU BUY ANOTHER MAGNESIUM
TimeRelease is designed to release magnesium gradually as the tablet breaks down. The amount you take and the way it is released are two different things. Watch how gradual release works.

The tablet meets fluid. Its outer surface starts to wear away.
Release continues as the outer material wears away towards the centre.
TimeRelease is designed to spread release over time. Two tablets provide 500 mg of elemental magnesium.
WATCH THE TABLET CHANGE

BEFORE YOU DECIDE
Straight answers on the formula, your routine and your money-back guarantee.
Sterling gives you a different release format to consider. The tablet is designed to release magnesium gradually as it breaks down, with 500 mg of elemental magnesium per serving. Magnesium supports energy, muscles and reduced tiredness. You also have our 60-day money-back guarantee, so you can decide for yourself.
The tablet is designed to release magnesium gradually as it breaks down. Think about two separate things: the dose is how much you take; the release is how it leaves the tablet. Sterling makes both clear.
Sterling uses a tablet designed for gradual release. Some capsules use coated beads to control release instead. Both formats can provide extended release; the format alone does not establish which works better. Compare product-specific release testing, the elemental magnesium amount and the directions.
Magnesium supports normal muscle and nervous system function. Cramps, tension and twitching can have several causes, so these symptoms do not automatically mean you need more magnesium. Sterling has not been shown to relieve these symptoms. If they persist, ask a healthcare professional about the cause.
Magnesium helps reduce tiredness and fatigue. It also supports normal energy production, muscle function, nervous system function and psychological function. That is the daily support this formula is built around.
Your concern makes sense. This is a gradual-release tablet, but that does not guarantee it will suit every stomach. Take it with food as directed. If magnesium has caused problems before, ask a pharmacist about the formula before trying it.
