Recommended Dosage and Usage

For adults, take one (1) tablet daily with a meal, or as advised by your health care professional. Each tablet delivers 500 mg of inositol hexanicotinate, providing a substantial dose of vitamin B3. If you are new to niacin supplements, consider starting with a lower dose to assess your tolerance. Do not exceed the recommended intake. As with any supplement, consult your doctor before use, especially if you have an underlying medical condition or are on medication.

What Is Flush-Free Niacin?

Niacin, also known as vitamin B3, is a water-soluble vitamin essential for converting food into energy. It also plays a role in maintaining the health of your skin, nervous system, and digestive system. However, the common form of niacin (nicotinic acid) can cause a temporary but unpleasant skin flush. Flush-Free Niacin use inositol hexanicotinate, a special bound form that is slowly converted to niacin in the body, thereby avoiding the flush. This allows you to enjoy the benefits of vitamin B3 without discomfort.

How Does Niacin Support Energy Metabolism and Overall Wellbeing?

Vitamin B3 contributes to normal energy-yielding metabolism, helping to reduce tiredness and fatigue. It also supports the maintenance of normal skin and mucous membranes, and contributes to normal psychological function and the normal functioning of the nervous system. These are all authorised health claims approved by the European Food Safety Authority (EFSA). By ensuring an adequate intake of vitamin B3, you can support your overall vitality and wellbeing.

Niacin Flush vs. Flush-Free: Which Is Better?

Standard niacin (nicotinic acid) can cause a prostaglandin-mediated flush – redness, warmth, and tingling – which many find unpleasant. Inositol hexanicotinate, the active ingredient in this supplement, is a bound form that releases niacin gradually, minimising the flush response. This makes it a more comfortable option for daily niacin supplementation. While immediate-release niacin may have a more pronounced effect on certain blood lipids, flush-free niacin provides a pleasant, sustained support for your body's metabolic processes.

Safety and Considerations

Flush-free niacin is generally well tolerated, but high doses (above 100 mg/day) may occasionally cause gastrointestinal discomfort, headache, or dizziness. Individuals with liver disease, peptic ulcers, glaucoma, or diabetes should use niacin supplements only under medical supervision. This product is a food supplement and should not be used as a substitute for a varied, balanced diet and a healthy lifestyle. Keep out of reach of children. If you are pregnant, breastfeeding, taking any medication or have a medical condition, consult your doctor before use.

Frequently Asked Questions

Can I take this alongside other supplements?

Generally, yes. However, avoid taking it with alcohol or hot beverages immediately after ingestion, as these may increase the risk of flushing. Always check with your health care provider for personalised advice.

How long until I notice benefits?

While individual results vary, consistent daily use is recommended. Niacin supports ongoing metabolic processes, so feeling the benefits may take a few weeks.
