Dietary supplements for preventing postnatal depression

Postnatal depression is a common condition that affects women and may impact on their babies. Common symptoms of postnatal depression include fluctuations in mood, mood changes, suicidal ideation and preoccupation with infant well‐being ranging from over‐concern to frank delusions. There is currently not much evidence regarding interventions that might prevent or treat postnatal depression. A diet lacking in certain vitamins, minerals or other nutrients may cause postnatal depression in some women. Correcting this deficiency with dietary supplements might therefore prevent postnatal depression. Examples of possible dietary supplements aimed at preventing postnatal depression include omega‐3 fatty acids, iron, folate, s‐adenosyl‐L‐methionine, vitamin B12 (cobalamin), B6 (pyridoxine), B2 (riboflavin), vitamin D and calcium.

Daily intake of 1 gr dietary calcium may have moderate protective effect on development of colorectal adenomatous polyps

There have been suggestions, based on observational studies and on laboratory markers, that dietary calcium may protect against colorectal cancer. This systematic review of the literature identified two well conducted randomised placebo‐controlled intervention studies involving 1346 subjects followed for 3‐4 years. The results suggest that there may be a moderate protective effect (OR 0.74; CI 0.58,0.95) for dietary supplementation of at least 1200mg elemental calcium per day on the development of colorectal adenomatous polyps. However, no trial has directly demonstrated an effect of calcium supplementation on the development of colorectal cancer itself.

Headaches: Diagnosis and Management of Headaches in Young People and Adults [Internet]

Many non-specialist healthcare professionals can find the diagnosis of headache difficult, and both people with headache and their healthcare professionals can be concerned about possible serious underlying causes. This leads to variability in care and may mean that people with headaches are not always offered the most appropriate treatments. People with headache alone are unlikely to have a serious underlying disease. Comparisons between people with headache referred to secondary care and those treated in primary care show that they do not differ in terms of headache impact or disability.

What are dietary supplements?

“Vitamins strengthen our immune system,” and “Omega 3 is good for your heart”: Dietary supplements are often marketed using a number of different promises, and they are available everywhere, from pharmacies and supermarkets to the internet. But do we really need all of these tablets, powders and capsules? What makes dietary supplements different from medicine and can they also be harmful?
