If you need to drink water to block hot flushes but find yourself getting up several times a night to urinate,
take your
niacin with dinner or breakfast. If you are restricting your fluid intake because of kidney disease, heart disease, water retention, or diuretic use, talk with your doctor before increasing your water intake.
Take niacin after consuming a small handful of nuts, such as 5-10 raw almonds, walnuts, or pecans. This will slow niacin’s absorption in the body.
