Twinlab - Niacin (B3) Caps Crystalline Pure 500 mg. - 100 Capsules

The Energy Your Body Needs
Niacin, also known as Vitamin B3, helps your body convert the carbohydrates in the food you eat into the energy your body needs for healthy function. It helps keep your nervous system, immune system, digestive system, skin, hair, and eyes operating normally. This essential nutrient also has been shown to improve your circulation, reduce cholesterol levels in your blood and is responsible for developing sex- and stress-related hormones in your body. Your body does not, however, store Niacin, so you require continuous intake, from food and possibly supplements. Twinlab Niacin Caps can provide you with the nutritive support you need for healthy skin, nerves, circulation, and your gastrointestinal tract, as well as the proper metabolism of food and immune-system support, in easy-to-swallow, fast-acting capsules.

    Why a Supplement?
    Your body does not store B Vitamins, so you need continuous doses of them to keep your internal systems functioning properly. Niacin is available through your diet, in foods including fish, lean chicken breast, red meats, portabella mushrooms, avocados, peanuts, green peas, peanuts, and sweet potatoes – and, in smaller quantities, in grains. According to the U.S. National Library of Medicine, the recommended daily allowance of Niacin is a minimum of 16 mg for men 14 years old and older, and at least 14 mg for women 14 years old and older, and more for pregnant and breastfeeding women. If you don’t get enough Niacin from your food, consider a daily supplement like Twinlab Niacin Caps.

    How Does it Work?
    Each dose of Twinlab Niacin Caps provides you with 500 mg of Niacin to assist with numerous metabolic functions in your body. In fact, because it provides energy on a cellular level and helps you maintain healthy cells, it’s essential for just about every function in your body. Maybe most important, it has been shown to help you maintain good circulation and help reduce your risk of heart disease. It is a powerful nutrient that inhibits cholesterol from settling into your liver and your arteries and may result in reduced LDL cholesterol levels.

    Catalyst for Nutrient Absorption
    Even when you eat a healthy diet, the nutrients you take in are of little value unless your digestive system absorbs them for use. Niacin helps your body absorb nutrients, so you are getting optimal use out of the foods you eat. Further, studies indicate that higher levels of Niacin in your body may be associated with reduced risk of memory loss, reduced skin irritations, healthy hair, and strengthened immunity. And because it helps balance the hormones in your body, including your sex hormones, Niacin supplementation may help improve your sex life, especially if you suffer from disorders like impotence or erectile dysfunction.

    Twinlab Crystalline Pure Niacin (B-3) Caps are easier to swallow and assimilate. Twinlab Crystalline Pure Niacin (B-3) is used to lower blood cholesterol, triglycerides, poor circulation, stress, leg cramps, headaches and poor immunity. Twinlab Crystalline Pure Niacin B3 Caps are free from most common allergens. Twinlab Crystalline Pure Niacin B3 Caps are yeast-free.

    This is Twinlab's mission for everything that has their name on it: vitamins, minerals, sports nutrition products, special formulas and amino acids.

    Twinlab's leadership is reflected in the firsts we have brought to the market:

    • The first complete line of amino acids
    • The first complete line of fish and marine oils
    • The most advanced and complete array of antioxidants
    • All-capsule vitamin and mineral line well tolerated by allergic individuals

    But Twinlab is not only motivated to be first, they are driven to be best. Twinlab insists on their own manufacturing (trust can't be transferred), which takes place in their state-of-the-art facility in American Fork, Utah.

    All told, Twinlab produces more than 500 different products. Why so many? Because everyone has their own needs, yet everyone has the same goal: to live healthier, to achieve wellness, to derive the maximum quality of life each and every day. To the extent Twinlab helps you achieve this, they consider it a privilege.


    As a dietary supplement, take one capsule daily or as directed. For best results, take after meals.
