Some Cautions for popular supplements
This generally very safe supplement should usually be taken with magnesium as the two minerals work in harmony together. As calcium is the main constituent of kidney stones it should not be taken on its own without medical approval where there is a history or risk of this condition. Where it is taken with approval from a professional then taking the supplement at mealtimes reduces the risk. Anyone suffering or with a history of cancer, hyperparathyroidism or sarcoidosis should also seek medical advice before taking calcium. There are certain medications that calcium may interfere with the absorption of. They are:Calcium channel blockers ,Terracycline and fluoroquinolone ,antibiotics ,Thyroid hormone and therefore calcium should only be taken with medical advice and even then at a different time of day to the medications.Calcium is best taken in the evening.
St Johns WortThis very effective herb for mild to moderate depression is used by millions worldwide. Recent research concluded that the herb was at least as effective as anti-depressant drugs and is now classified as prescription medication in some countries.The caution for St Johns Wort is that it interacts with other drugs causing them to metabolise through the body too quickly. This is obviously very significant for people on the contraceptive pill or the blood-thinning drug warfarin, who are at risk of a stroke. The Medicines Control Agency issued a warning on March 1st 2000 that patients who are on a long list of drugs should stop taking St John's wort until they have consulted their GP or pharmacist. Medications for asthma, epilepsy, depression, migraine and heart problems are all implicated. Hypericin, the active ingredient in St John's wort, reacts with sunlight and so those taking the remedy should limit their unprotected sun exposure. This is particularly significant for people who suffer from seasonal affective disorder, who might combine a course of St John's wort with light-box therapy.
