Moderate Evidence

Primary Stack (Tier 1)

Omega-3 Fatty AcidsB
3-4g EPA+DHA daily

Improves blood flow; reduces blood viscosity; anti-inflammatory

6 studies | 300 participants
Ginkgo BilobaB
120-240mg standardized extract daily

Improves peripheral circulation; may reduce attack frequency

5 studies | 250 participants

Supporting Stack (Tier 2)

L-ArginineC
3-6g daily in divided doses

Nitric oxide precursor; supports vasodilation

4 studies | 150 participants
Evening Primrose OilC
3-6g daily (providing ~270-540mg GLA)

GLA supports prostaglandin production; may improve circulation

4 studies | 150 participants
Vitamin EC
400-800 IU daily

Antioxidant; may improve blood flow

3 studies | 100 participants

How It Works

Raynaud's phenomenon is a condition where blood vessels in the fingers and toes temporarily narrow in response to cold or stress, causing them to turn white, then blue, then red as blood flow returns.

TYPES:

•Primary Raynaud's: No underlying disease; more common; usually mild
•Secondary Raynaud's: Associated with another condition (lupus, scleroderma, etc.); can be more severe

TYPICAL ATTACK:

1. Fingers/toes turn white (vasospasm - no blood flow)

2. May turn blue (deoxygenation)

3. Turn red and throb as blood returns

4. May feel numb, cold, or painful

TRIGGERS:

•Cold temperatures (main trigger)
•Emotional stress
•Certain medications (beta-blockers, migraine drugs)
•Vibrating tools
•Smoking

PREVENTION:

•Keep entire body warm (not just hands/feet)
•Wear layers, gloves, warm socks
•Avoid cold exposure
•Don't smoke
•Manage stress
•Avoid vasoconstrictive medications if possible

MEDICAL TREATMENTS:

•Calcium channel blockers: Nifedipine most common
•Topical nitrates: Applied to fingers
•PDE5 inhibitors: Sildenafil for severe cases
•Prostacyclin analogs: For severe secondary Raynaud's

WHEN TO SEE A DOCTOR:

•Severe or frequent attacks
•Skin ulcers or sores
•One-sided symptoms
•Associated joint pain or skin changes
•Onset after age 30

* Omega-3s and ginkgo may improve circulation.

* L-arginine supports blood vessel dilation.

* Lifestyle measures are essential.

Expected timeline: Supplements may reduce attack frequency within weeks to months. Lifestyle modifications often provide immediate benefit.
