Not all magnesium forms work the same way. The form decides how well your body absorbs it, how it feels on the stomach, and when to take it. This guide compares the four magnesium options in the EnduranceVitals range, so you can match one to your goal.
Key takeaways
- Magnesium supports muscle function, the nervous system and the reduction of tiredness.
- Magnesium citrate is a well-absorbed, all-round choice for daily use.
- Magnesium glycinate is gentle on the stomach and popular in the evening.
- A triple complex combines several forms in one capsule for broad coverage.
- Vitamin B6 is added to many magnesium products to support normal nervous system function.
Why magnesium matters for active people
Magnesium is involved in hundreds of processes in the body. It contributes to normal muscle function, energy metabolism and electrolyte balance.
Hard training increases losses through sweat. A demanding week does the rest. That is why magnesium is one of the most used minerals among athletes and busy people alike.
Signs of low intake can include tired muscles, cramping and restless sleep. Food sources such as nuts, seeds and leafy greens come first. A supplement helps close the gap.
The four magnesium forms in our range
Magnesium citrate with vitamin B6
Citrate is magnesium bound to citric acid. It is one of the best-studied and most readily absorbed everyday forms.
OstroVit Magnesium Citrate + B6 (90 tabs) pairs magnesium citrate with vitamin B6, which contributes to normal psychological function. A solid default if you just want one tub that works.
Magnesium glycinate for calm evenings
Magnesium glycinate binds the mineral to glycine, an amino acid. This chelated form is known for being easy on the stomach.
Many people take OstroVit Magnesium Glycinate (90 caps) with the last meal of the day as part of a wind-down routine. If citrate feels too harsh on your gut, glycinate is the usual switch.
Triple magnesium complex
Why choose one form when you can combine three? OstroVit Triple Magnesium + B6 P-5-P (90 caps) blends complementary magnesium forms in one capsule and adds P-5-P, the active form of vitamin B6.
This suits people who want broad coverage without juggling several products.
Classic MG+B6 tablets
OstroVit MG+B6 (90 tabs) is the simple, budget-friendly staple: magnesium plus vitamin B6 in a familiar tablet. A practical entry point if you have never supplemented magnesium before.
Which magnesium form should you choose?
Match the form to the goal, not the other way round:
- Everyday training support: magnesium citrate.
- Sensitive stomach or evening use: magnesium glycinate.
- One product, broad coverage: the triple complex.
- Simple and affordable: classic MG+B6 tablets.
Whichever you pick, consistency beats dose. Magnesium works best taken daily over weeks, not as a one-off fix.
How and when to take magnesium
Take magnesium with a meal to improve tolerance. Splitting a daily dose into two servings can help if larger amounts unsettle your stomach.
Timing is flexible. Morning works. Many prefer the evening, especially with glycinate. Stay within the serving size on the label, and talk to a doctor first if you take medication or have a kidney condition.
