Niacina del siglo XXI, de liberación prolongada, 110 comprimidos

What is niacin and why is it important?

Niacin, also known as vitamin B3, is an essential water-soluble vitamin that the body needs to convert food into energy. It plays a key role in energy metabolism, nervous system function, and the maintenance of skin and mucous membranes. Unlike other B vitamins, niacin stands out for its ability to support blood circulation and maintain healthy cholesterol levels at appropriate doses.

21st Century Extended Release Niacin offers 110 tablets designed to release the vitamin gradually, which helps maintain stable levels in the body and minimizes the digestive discomfort sometimes associated with immediate-release niacin.

Key benefits of niacin

Niacin contributes to multiple bodily functions supported by the European Food Safety Authority (EFSA):

• Normal energy metabolism: Helps convert carbohydrates, fats, and proteins into usable energy.
• Normal functioning of the nervous system: Maintains communication between neurons and proper nerve function.
• Maintenance of skin and mucous membranes: Promotes cell regeneration and the integrity of the skin barrier.
• Reduction of tiredness and fatigue: By supporting energy production, it helps reduce feelings of exhaustion.

Additionally, niacin is known for its role in cardiovascular health, as it helps maintain normal cholesterol and triglyceride levels when used under medical supervision.

Why choose extended release?

Immediate-release niacin can cause a flushing effect due to rapid vasodilation. 21st Century's extended-release formula gradually releases niacin, significantly reducing this side effect and improving tolerance. This makes it an ideal choice for those who want to benefit from niacin without discomfort.

Furthermore, the extended-release tablet allows for more convenient dosing, as only one tablet is taken daily with a meal.

Who can benefit from niacin?

Niacin is suitable for adults seeking energy support, nervous system, and skin health. It is especially useful for:

• People with restrictive diets: Vegans and vegetarians may have lower niacin intake, as primary sources are meats, fish, and dairy products.
• Athletes or active individuals: To maintain high energy levels and muscle recovery.
• Older adults: Vitamin B absorption can decrease with age.
• Those seeking cardiovascular health: Always under medical advice.

This supplement is vegan-friendly, gluten-free, and contains no genetically modified organisms (non-GMO).

How to take this supplement

It is recommended to take one tablet daily, preferably with a meal to facilitate absorption. Do not exceed the recommended dose. Extended-release tablets should not be broken, chewed, or crushed, as this would alter their release mechanism.

Store in a cool, dry place, out of reach of children. If you are pregnant, breastfeeding, or undergoing medical treatment, consult a healthcare professional before taking this supplement.
