Bisglycinate is the gentler choice – fewer stomach issues, no laxative effect. Citrate is also well absorbed, but at higher doses it can affect digestion. For long-term use, bisglycinate is the better option.

Between 300 and 400 mg of elemental magnesium – daily. SYNAPTO provides exactly that: 400 mg per daily dose, 107% of the reference value.

Many people notice the biggest difference in the evening – the nervous system settles down and the muscles relax. If you prefer to spread it throughout the day, that works well too and provides a more stable magnesium level in the blood.

Yes – and it actually makes sense. Magnesium isn't a medication but an essential mineral your body needs every day. For healthy adults, long-term supplementation is safe.

Most supplements just deliver magnesium – and that's it. SYNAPTO combines magnesium bisglycinate with GABA and glycine, two amino acids that specifically support the nervous system. Not more magnesium – a more thoughtful system.

GABA is a messenger substance the body produces itself that regulates the nervous system. In combination with magnesium and glycine, it supports normal function of the nervous system. You're not getting three ingredients – you're getting one formula.

Yes, entirely. No gelatine, no lactose, no animal-derived ingredients. All ingredients are plant-based.

In Germany – to strict European quality standards.

180 capsules, 3 per day – that's exactly 60 days. Two months' supply in one bottle.

Take 3 capsules daily with or after a meal with plenty of liquid. If you have a sensitive stomach, split the dose into 3 portions throughout the day.

Magnesium bisglycinate is known for being well tolerated. At very high doses, it may cause loose stools – at the dosage in SYNAPTO, this generally doesn't occur.

In most cases, yes. Just make sure you're not taking other magnesium supplements at the same time, which could push your total intake too high. If in doubt, check with a doctor.

Pregnant or breastfeeding women, and people under 18, should seek medical advice before use. The same applies to those with kidney conditions.

Magnesium is proven to contribute to normal psychological function and to the reduction of tiredness and fatigue – these are EU-approved, recognised claims, not marketing promises.

Magnesium contributes to normal muscle function – this is scientifically established. A deficiency is often linked to cramps, especially during exercise or stress.

The most common signs: muscle cramps, persistent fatigue, irritability, difficulty concentrating. It can only be reliably confirmed with a blood test from a doctor.

Yes. During physical exertion you lose magnesium through sweat – more than in everyday life. Athletes therefore often have an increased need that diet alone doesn't always cover.
