Most individuals who’ve undesirable levels of cholesterol and may’t enhance them sufficiently through weight-reduction plan and train are prescribed statin medicine. However there’s additionally a vitamin, niacin—often called Bthree—that in very giant doses can enhance levels of cholesterol and scale back the danger of coronary heart assaults. In reality, when niacin’s useful impact was found in 1955, it turned the primary remedy for prime ldl cholesterol.
Who wouldn’t choose to take a vitamin over a prescription drug, you may ask. However it’s not that easy.
Although categorised as a dietary complement, high-dose niacin, in impact, is a drug, whether or not you purchase it over-the-counter or by prescription. And like all drug, it has potential unintended effects and ought to be taken below medical supervision.

It additionally lowers triglycerides, fat within the blood that may improve the danger of coronary heart illness.
For these causes, niacin could also be choice for individuals who can’t tolerate statins effectively and for individuals who have very low HDL and/or excessive triglycerides. Furthermore, niacin helps individuals who have elevated ranges of small, dense LDL particles, which improve coronary threat.

However you’ll additionally discover different kinds on the market, resembling niacinamide and inositol hexanicotinate, which have little or no impact on ldl cholesterol.
As well as, there are three classes primarily based on the speed of launch of the niacin:
- Fast-release niacin is efficient and least costly, however causes extra flushing. It needs to be taken two or thrice a day.
- Sustained-release/extended-release niacin causes much less flushing. Nevertheless, some over-the-counter formulations could also be much less efficient and improve the danger of liver toxicity. The extended-release type bought by prescription (Niaspan is the best-known model) is efficient, least more likely to trigger intense flushing and safer for the liver—but it surely prices much more than brand-name statins. An over-the-counter sustained-release preparation known as Slo-Niacin is much like Niaspan however a lot cheaper.
