Supports energy production and skin health, but watch out for the 'niacin flush'.
A harmless side effect of the nicotinic acid form. It's a warm, itchy, red feeling on your skin that lasts about an hour.
Easy. Take the 'niacinamide' form instead. All the B3 benefits, none of the flushing.
Nope. It's uncomfortable and weird, but not dangerous. It's just blood vessels dilating.

They are two forms of Vitamin B3. Niacin (nicotinic acid) causes the flush and affects cholesterol. Niacinamide doesn't cause a flush and is better for skin.
Yes, but only at very high, prescription-level doses of nicotinic acid and under a doctor's supervision. Don't self-treat cholesterol with this.
Almost certainly. Deficiency is rare in developed countries. Chicken, tuna, turkey, and fortified cereals are packed with it.
Most research uses 0.3g daily. Below 0.1g, you're probably wasting money. Above 1.0g, no extra benefit. The curve plateaus. Safe upper limit ~ 3.0g.
Niacin is converted into NAD+ and NADP+, coenzymes involved in hundreds of metabolic processes, including energy production, DNA repair, and cell signaling.
Niacin's role in energy metabolism is well-established. Its benefits for cholesterol management at higher (prescription) doses are also recognized. However, the evidence for benefits at typical supplement doses for the average person is less robust, especially beyond correcting deficiency.
Naturally abundant in meat, poultry, fish, nuts, legumes, and fortified grains like bread and cereal.
