Side Effects

Magnesium supplementation is likely well tolerated for most people but may cause stomach upset, diarrhoea, nausea and vomiting in some individuals.
Caution should be used in patients with kidney problems as poorly functioning kidneys do not excrete magnesium from the body well leading to dangerous levels of serum magnesium levels.
Vitamin B6 is toxic when ingested in mega doses i.e. greater than 200 mg per day for a prolonged period of time and may cause peripheral neuropathy.
You can also refer to the CMI for this product for symptoms and side effects.

Additional information





With ingredients like Bifidobacterium longum and Saccharomyces boulardii, you’d think it’s pretty complicated. However, with over 20 years’ experience and our own research lab we know what we are doing, so you can leave the complicated to us. Long before the gut health hype began, Medlab was formulating its own probiotics and supplements, which are specially designed to combat the increasing prevalence of modern-day chronic diseases. Medlab’s products are designed to restore human health by targeting the problem where it often starts: the gut. Study after study is demonstrating how important the gut is to overall general health - it’s not called the ‘second brain’ for nothing. This gut-centric approach is at the forefront of modern-day disease prevention and treatment are at the heart of Medlab’s scientific philosophy. We believe that more science means more out of your supplement.
