Dr Clark Niacin (Vitamin B3) Supplement – 25mg, 100 Gelatin Capsules

Description
Additional Information

Health Benefits of Niacin Supplementation

Niacin (vitamin B3) helps your body convert food into energy, supporting normal metabolism of carbohydrates, fats, and proteins. It also contributes to healthy skin and nervous system function. In Canada, niacin is recognized for helping maintain healthy cholesterol levels as part of a balanced diet. These statements have not been evaluated by Health Canada. This product is not intended to diagnose, treat, , or prevent any disease.

Niacin vs. Niacinamide – Which Form Is Right for You?

This supplement contains nicotinic acid, the form of niacin most associated with circulatory benefits and cholesterol support. Unlike niacinamide, nicotinic acid may cause a temporary flushing sensation—warmth and redness that typically fades with continued use. If you prefer a non-flush option, niacinamide might be a better choice, but for classic niacin effects, nicotinic acid remains the preferred form.

Recommended Dosage and How to Take Niacin

Each capsule provides 25 mg of niacin, a moderate dose suitable for daily maintenance. To minimize flushing, start with a lower dose and increase gradually. Take one capsule daily with food and a full glass of water. Do not exceed the recommended dose unless advised by your healthcare practitioner. Higher doses (over 50 mg) may require medical supervision due to potential side effects like flushing, itching, or gastric upset.

Potential Side Effects and Safety Considerations

The most common side effect of nicotinic acid is flushing, which often subsides as your body adjusts. Taking niacin with food reduces this effect. Rarely, high doses may affect the liver; therefore, stick to the recommended dosage. Consult your healthcare practitioner before use if you have liver disease, gout, or stomach ulcers, or if you are taking blood pressure or diabetes medications. This product is free from common allergens like soy, nuts, and milk, and contains No magnesium stearate, silica, or sulfates. Keep out of reach of children.

Frequently Asked Questions

Can I take niacin on an empty stomach?

It’s best to take niacin with food to reduce the chance of flushing and stomach discomfort.

Is 25 mg of niacin enough?

For general wellness and to support normal metabolic functions, 25 mg is a suitable daily amount. For specific health goals, consult your healthcare practitioner.

Does niacin interact with medications?

Niacin may interact with blood pressure medications, blood thinners, and diabetes drugs. Always consult your healthcare practitioner before combining supplements with prescription medications.

How to Choose a High-Quality Niacin Supplement

Dr Clark Niacin features a clean formula—only niacin and a gelatin capsule—with No unnecessary fillers or additives. It is non-GMO and suitable for many dietary restrictions. When selecting a niacin supplement, look for third-party testing (e.g., USP or NSF) to ensure purity and potency. This product’s simple ingredient list reflects a commitment to quality, though it does not carry such certifications.

What Is Vitamin B3 (Niacin)?

Vitamin B3, or niacin, is a water-soluble vitamin that plays a key role in cellular metabolism, DNA repair, and signaling pathways. It occurs in two main forms: nicotinic acid (the form in this supplement) and niacinamide. Nicotinic acid is particularly known for its cardiovascular and circulatory benefits, making it a popular choice for those seeking these effects.
