The NHS has issued a warning urging older adults to refrain from taking a specific supplement without consulting a doctor first. While it is advised that all adults consider taking vitamin D supplements to compensate for the lack of sunlight during winter months, the notion that common vitamins can prevent colds has been debunked by the NHS.
The health service highlighted that taking too much of certain supplements can have detrimental effects, even for younger individuals. Overconsumption can lead to symptoms such as stomach pain, nausea, and diarrhoea, emphasising the importance of moderation when it comes to supplements.
In particular, older adults are cautioned to avoid potassium supplements unless specifically advised by a healthcare professional. Potassium, crucial for fluid balance and heart function, can typically be obtained through a diverse diet that includes foods like parsnips, broccoli, nuts, seeds, and meats.
While adults aged 19 to 64 require 3,500mg of potassium daily, it is suggested that this amount can be met through dietary sources. In cases where potassium levels are low, supplements or potassium-rich foods may be recommended to prevent potential heart issues.
The Department of Health and Social Care has stressed that older individuals, whose kidneys may have decreased efficiency in processing potassium, should exercise caution when considering potassium supplements. Both low and high potassium levels can pose serious risks to heart health, underlining the significance of maintaining a balanced intake.
If concerned about potassium levels or experiencing heart-related symptoms, individuals are advised to consult a GP for appropriate guidance and possible testing. By prioritising a well-rounded diet and seeking professional advice, older adults can safeguard against potential adverse effects associated with certain supplements.
