Combined calcium, magnesium and potassium supplementation for the management of primary hypertension in adults

Elevated blood pressure (BP) or hypertension can lead to cardiovascular disease, stroke and renal disease. Epidemiological studies suggest that changing the dietary levels of calcium, potassium, magnesium or sodium can affect BP in some people. This systematic review focuses on the effects of concurrently attempting to change any combination of calcium, magnesium, or potassium levels in the diet of adults with primary hypertension.

Oral potassium supplementation for high blood pressure in adults

This review examines whether taking potassium supplements can be recommended for treating adults with high blood pressure from no known cause. The results of the trials varied a lot: some trials found potassium lowered blood pressure much more than a dummy drug (placebo), while others found little difference between potassium and placebo. Overall no significant reduction in blood pressure from taking potassium supplements was found.

Iodised salt for preventing iodine deficiency disorders

Iodine deficiency causes mental retardation in children as well as enlarged thyroid glands (goitre) and deficiencies in thyroid hormones in people of all ages. It still exists in large parts of the world. This review looked at studies of iodised salt in the diet that included a comparison group. Six studies, most of them in children but some also in adults, were included. Iodine in the urine increased in all but one studies, but there was some concern that small children did not eat enough salt to achieve adequate iodine status. Some studies, but not all, also showed a reduction in the enlargement of the thyroid gland (goitre) that can accompany lack of iodine in the diet. Adverse effects were not reported, but these may not have been studied adequately. More high quality long term studies measuring outcomes related to child development, to deaths associated with iodine‐deficiency and to adverse effects are needed.

Preventing kidney stones

People who have had a kidney stone are quite likely to get another one. To prevent that from happening, it's usually enough to drink plenty of water and change your diet. Some people will still end up having kidney stones again and again. Medication is then an option.About 30 to 50 out of 100 people who have had a kidney stone can expect to have another within five years. About 10 out of 100 will regularly develop kidney stones. Many people who are affected want to know what they can do to prevent new kidney stones from forming.Because kidney stones can have so many different possible causes, the first thing to find out is the chemical composition of the stones. The levels of some substances in your blood and urine may also suggest a particular cause. About 80% of all kidney stones are made of calcium oxalate or calcium phosphate. Uric acid stones make up about 5 to 10% of all kidney stones. The rest are made of struvite, cystine or other less common substances.Drinking enough fluids and possibly making changes to your diet is usually all you need to do to lower your risk of kidney stones. Medicine for preventing kidney stones may also be a good option for people who have a higher risk.
