Sustained – Release Niacin, 500mg – 120 Tablets – Doctor’s Best<\/strong><\/h2>\n

Sustained – Release Niacin, 500mg – 120 Tablets – Doctor’s Best<\/strong> is a food supplement<\/strong> with niacin<\/strong> (nicotinic acid), presented in sustained-release<\/strong> tablets. In this way, the product provides the vitamin gradually over time. In addition, the formula includes excipients of plant origin and does not contain gluten, according to the manufacturer’s information.<\/p>\n

What it is used for<\/strong><\/h3>\n

Niacin (vitamin B3)<\/strong> participates in essential metabolic processes. Thus, it contributes to energy-yielding metabolism<\/strong> and to the normal functioning of the nervous system<\/strong>. Additionally, it contributes to normal psychological function<\/strong> and to the maintenance of normal skin and mucous membranes<\/strong>. Therefore, it can be used as nutritional support when seeking to supplement vitamin B3 intake, always within the context of a balanced diet.<\/p>\n

On the other hand, this product features sustained-release<\/strong> technology, which may help limit the occurrence of skin flushing (flush)<\/strong> in some people. However, the reaction may occur, especially at the beginning of use.<\/p>\n

Composition or Main Characteristics<\/strong><\/h3>\n

Each tablet of Sustained – Release Niacin, 500mg – 120 Tablets – Doctor’s Best<\/strong> provides:<\/p>\n

    \n
  • Niacin<\/strong> (as nicotinic acid<\/strong>): 500 mg<\/strong> per tablet<\/li>\n
  • Sustained-release form<\/strong> (manufacturer’s technology, with reference to niaXtend\u00ae)<\/li>\n
  • Excipients: vegetable waxes<\/strong> (rice bran and\/or carnauba wax), stearic acid<\/strong>, magnesium stearate<\/strong> (plant origin) and silica<\/strong><\/li>\n<\/ul>\n

    Likewise, the manufacturer indicates characteristics such as suitable for vegans<\/strong> and gluten-free<\/strong>. However, it is always recommended to confirm the label of the batch received.<\/p>\n

    Directions for use<\/strong><\/h3>\n

    Take 1 tablet per day<\/strong>, with food. This helps promote more comfortable use. Alternatively, follow the recommendation of a healthcare professional trained in nutrition. Do not exceed the stated daily dose, except under clinical supervision.<\/p>\n

    Important information<\/strong><\/h3>\n

    In particular, niacin<\/strong> may cause a sensation of warmth<\/strong>, itching<\/strong> or redness<\/strong> (flush), especially at the beginning. In addition, alcoholic beverages or hot drinks taken close to the time of use may intensify these effects.<\/p>\n

    Do not use Sustained – Release Niacin, 500mg – 120 Tablets – Doctor’s Best<\/strong> without medical advice if you are pregnant<\/strong>, breastfeeding<\/strong>, have liver disease<\/strong> or kidney disease<\/strong>, or if you take medication. In this way, the risk of interactions and undesirable effects is reduced. The manufacturer warns of the risk of liver changes<\/strong> with high doses of niacin; therefore, avoid doses higher than those recommended without supervision.<\/p>\n

    Store in a cool<\/strong>, dry<\/strong> place. Keep out of the sight and reach of children. Additionally, food supplements do not replace a varied diet and a healthy lifestyle.<\/p>\n","protected":false},"excerpt":{"rendered":"
