Is it worth taking magnesium before training?

Answer

No. There is no pre training effect and no claim describing one. Anchoring a daily serving to training also guarantees missed days, since training is not daily.

Key takeaways

Does pre training timing help?
No. Magnesium works through a daily intake and circulating levels are tightly regulated.
Why is anchoring to training a mistake?
Training happens two or three days a week, so the serving gets missed four or five days out of seven.
What is the better anchor?
Breakfast, or whatever else happens every day regardless of rugby.

No pre training effect

Magnesium is a mineral with a daily reference intake, and the authorised claims describe contributions to normal function at adequate intake rather than effects tied to a moment.

A capsule an hour before a session does not change what is available during it. Futuro Labs Magnesium Glycinate provides 300mg elemental per two capsule serving at 22p a day, and that works by being taken consistently.

The anchoring problem

Attaching a daily serving to training feels natural because that is when a player thinks about rugby. It is the single most common design error, because training is not daily.

A serving anchored to Tuesday and Thursday is missed the other five days, and for a product working through cumulative intake that is most of the point lost. Breakfast survives a Christmas break, a cancelled session and a week off with a cold.

What does belong before a session

Being fuelled, which for an evening session after work means having eaten something in the afternoon rather than nothing since lunch. Being hydrated across the day rather than drinking at the door. And a warm up long enough to matter, particularly in cold weather. None of those is bought and all of them change a session more than any capsule.
