Raynaud's Phenomenon

Inositol hexanicotinate, a form of vitamin B3, supports peripheral circulation without causing the flushing side effect associated with standard niacin. Raynaud's phenomenon typically responds well to vitamin B1 in the fat-soluble form benfotiamine. Benfotiamine is a targeted intervention for Raynaud's phenomenon, separate from the general ice-water cold-feet protocol. Raynaud's phenomenon causes fingers and sometimes toes or ears to turn blue or white in cold because small blood vessels overreact and constrict dramatically. Raynaud's phenomenon is an autonomic nervous system disorder causing vasospasm, making fingers and toes turn blue due to failure to pump blood effectively. Vitamin B1 (thiamine) deficiency can cause Raynaud's by impairing autonomic nervous system control over blood vessel dilation and constriction.
