The issue of receiving informal care and support is very important in the context of population ageing and socio-economic changes. Health status and social support are significant determinants of subjective well-being. Not sufficient social support of its lack is detrimental for both health status and psychological well-being at all ages, including older adults. This paper examines the effect of health status and received informal care on well-being among people aged 65 years and more in selected European countries. We analyze the data coming from the 4^th wave of the Survey of Health, Ageing and Retirement in Europe (SHARE). Well-being is captured by the short version of the CASP questionnaire (CASP-12), also use the information on depression symptoms (EURO-D scale) and general life satisfaction as proxy for well-being. The linear regression models were employed, since all dependent variables were treated as continuous ones. The results confirmed that deterioration of health status has a negative impact on well-being (in terms of CASP-12 and life satisfaction) and a positive effect on the number of depression symptoms. While receiving informal care (both from out of a household and within a household) was negatively related to well-being and positively to the depression index. It may be explained by the fact that informal care has a negative effect on psychological morale which may alter confidence in one’s abilities, self-esteem and lead to the resignation from some activities and therefore a deterioration in health status.
