Vitamin B3, also known as niacin, has scientific validation for its use in supporting poor circulation, particularly in the context of peripheral vascular diseases such as peripheral artery disease (PAD). Niacin is well-known for its lipid-modifying effects, including decreasing LDL cholesterol, lowering triglycerides, and raising HDL cholesterol. These effects can help improve vascular health and may indirectly benefit circulation. Additionally, niacin causes peripheral vasodilation, which leads to the characteristic "niacin flush"—a temporary reddening of the skin due to increased blood flow. This vasodilatory property has led to its use in attempts to improve peripheral circulation.

Clinical evidence specifically supporting niacin for "poor circulation" outside of lipid disorders is moderate. Some studies have observed improved blood flow and endothelial function in patients taking niacin, but these are often secondary outcomes in trials primarily targeting cholesterol levels. There is limited direct evidence for niacin as a primary treatment for circulation problems unrelated to dyslipidemia. The use of niacin for circulation is more strongly supported in cases where poor circulation is secondary to atherosclerosis or lipid abnormalities, rather than in cases of idiopathic or non-atherosclerotic circulatory issues.

In summary, there is scientific rationale and some moderate clinical evidence backing the use of vitamin B3 (niacin) to support circulation, especially when poor circulation is associated with vascular disease and abnormal blood lipids. However, it is not a first-line treatment for circulation issues in the absence of these conditions.
