Understanding Niacin Supplements: Benefits and Risks
Niacin supplements, also known as vitamin B3, have been used primarily to address deficiencies. However, their applications have broadened to include managing high cholesterol and triglyceride levels. This water-soluble vitamin is essential for converting food into energy, found abundantly in foods such as chicken, nuts, beans, and grains.
A significant study involving over 25,000 patients revealed that niacin, when used alongside cholesterol-lowering medications, offered minimal additional benefits compared to statins alone. Furthermore, the research indicated that taking niacin could be linked to concerning side effects, including the development of new diabetes or worsening existing diabetic conditions.

While niacin is vital for various bodily processes and is generally safe at moderate levels, it operates differently from other supplements, as noted by dispensing optician Krina Halai from Feel Good Contacts. “Unlike other supplements like vitamin B12, zinc, or omega-3 fatty acids, niacin has a narrower safety margin,” she explained.
High doses of niacin can potentially lead to a condition known as niacin-induced maculopathy, which may cause fluid accumulation in the macula, resulting in symptoms such as blurred or distorted vision.
“Niacin can disrupt the eye’s normal functioning by creating fluid-filled pockets in the macula,” Halai advised. The relationship between high doses of niacin and eye health has been recognized for some years; however, retinal damage remains extremely rare and is usually reversible with prompt diagnosis and treatment.
She emphasized the common misconception that taking larger amounts of certain supplements results in better health outcomes.

The promising aspect is that instances of such conditions are exceedingly rare, and they can often be reversed if detected early. Rapidly discontinuing niacin is crucial for reversing any vision changes that have occurred.
In summary, while niacin is an important nutrient with potential health benefits, it is essential to use it judiciously. Awareness of its effects, particularly concerning eye health, can help ensure safe usage and mitigate risks.
