Use caution when taking niacin in high doses. Niacin in the form of nicotinic acid, is a vasodilator, meaning it opens up the capillaries and allows increased blood flow to the skin. This causes the characteristic “niacin flush” with symptoms that can include reddening of the skin, increased warmth, skin tingling, and itching. It usually starts at the forehead and works its way down the body. The niacin flush is harmless and will pass, but this can be uncomfortable for some people.

High dose niacin is not recommended for first-time niacin users. If you flush with low dose niacin, you can expect a more intense and prolonged flush if you jump to a high dosage without a gradual build up. To avoid an intense flush, start with a low dose niacin such as our 25 mg Niacin. If this low dose makes you flush, open a capsule and take only a portion of the niacin power and gradually increase the amount of powder in each dose. Continue gradually increasing your niacin dose if working up to higher doses of niacin. Each time niacin is taken, the flush is repeated but to a lesser degree.*

Why high-dose Niacin?
Abram Hoffer, MD, PhD was a pioneering niacin researcher who advocated the use of nutrition-based medicine, including regular, prolonged therapeutic doses of niacin, for the prevention and treatment of a wide spectrum of health problems.*

In a book co-authored by Dr. Hoffer, Niacin: The Real Story, researchers challenged the Safe Upper Limit (UL) of niacin set forth by the Institute of Medicine, which is currently 35 mg per day for adults. Hoffer and his associates debated the legitimacy of the government standard UL when, to date, there is no evidence to prove that high doses of niacin are harmful to human health.*

Dr. Hoffer’s standard therapeutic niacin recommendation was 3,000 mg per day divided into three doses. He recommended taking niacin with a meal for improved absorption.*

Niacin (Vitamin B3) helps the body utilize proteins, fats and carbohydrates for energy, and also supports nerve and skin health. Niacin may help the body’s efforts to lower cholesterol and supports digestive health.*

How to work yourself up to 3,000 mg of pure Niacin per day:
You may be wondering how to build up to 3,000 mg of pure niacin per day, as described by Dr. Abram Hoffer in Niacin: The Real Story.

You may not know that time released niacin, which is designed to limit the effects of flushing, has been found to be toxic to the kidneys, so it should be avoided. Take only pure niacin.*

Keep in mind that niacinamide is an option, although not as potent as pure niacin, for those who cannot tolerate the niacin flush. When taking pure niacin you may experience flushing from the top of your head down to your lower back. This is a harmless reaction but you may want to limit the intensity of the flush by starting with small amounts of niacin.

For example, start with 25 mg and keep taking this amount until you are comfortable with the effects of the flush. Then increase to 50 mg (this may be possible by the third dose). Increase dose to 100 mg, 200 mg, 500 mg and eventually 1,000 mg per dose, three times a day, using a similar wait time between each increase. You can go slower or faster depending on your comfort level.

Always talk to a qualified healthcare professional prior to taking vitamins and supplements in high doses, as discussed here.

Ingredients
Niacin, gelatin (bovine) capsule

Suggested Use
Adults take 1 capsule daily, preferably with a meal, or as directed by a healthcare professional. Consult with a physician before administering to children.

Store at room temperature. Keep out of reach of children.

Frequently Asked Questions
Q: What is the capsule size?
A: Capsule size 0.

Q: What type of capsule does this product come in?
A: This comes in a gelatin capsule. The gelatin is derived from bovine hide (beef skin).

Q: What is the difference between niacin and niacinamide?
A: The difference between niacin and niacinamide lies in the chemical composition of each form of vitamin B3. While niacin contains an organic acid group, niacinamide contains an amino group. This difference in composition allows each form of B3 to carry out specific tasks in the body. For some purposes, however, the two forms can be used interchangeably. The body can convert niacin into niacinamide with help from the amino acid tryptophan.

Q: Will this product cause skin flushing?
A: Niacin causes capillaries to dilate, which allows more blood flow to the skin. For some people, this causes a "niacin flush" with symptoms that include reddening of the skin, increased warmth, tingling, and itching. The flush typically starts at the forehead and works its way down the body. The niacin flush is harmless and will pass but may cause minor discomfort for people. If you're concerned about flushing, try niacinamide instead.

Unlike others, we are the actual manufacturers who take pride in our craft, overseeing the entire production process to ensure that each bottle meets our high standards. With more than 31 years of expertise and over 10 million bottles produced, you can rest assured that you're choosing a partner dedicated to authentic wellness. We don’t outsource to the lowest bidder.

Guaranteed Authenticity: Every batch of Niacin 500 is carefully sourced and undergoes rigorous testing for ID, purity, potency, and microbiology before, during, and after manufacturing.

Just Pure Ingredients: At Dr. Clark Store, we stand against adulteration. Our rigorous testing reveals that an estimated 30% of bulk supplement powders in the U.S. market contain added fillers and/or come from incorrect species or plant parts. Unlike importers who operate according to FDA 21 CFR 117 and often rely on analyses done by the manufacturer abroad, we conduct thorough tests on all incoming materials in our full-size laboratory, guaranteeing the integrity of our products.

Carrageenan and Surfactant-Free Capsules: FDA regulation 21 CFR 101.100(a)(3)(ii) allows manufacturers to avoid disclosing ingredients in food if present at “insignificant” levels. This is why "Veggie Capsules" may contain carrageenan. Dr. Clark Store ensures the use of only the finest BSE-free gelatin capsules, free from carrageenan, surfactants, and prion risks. Our dedication to purity dates back over 30 years, ensuring safety and quality in line with Dr. Hulda Clark's original vision.

No Magnesium Stearate and No Hidden Processing Aids: True to Dr. Clark's vision, we never use magnesium stearate or any toxic processing aids in our products. Our commitment to transparency means all ingredients are clearly declared on the label, offering you peace of mind and a product you can trust. Again because of FDA’s lacking regulation 21 CFR 101, many brands contain magnesium stearate without it being declared on the label.

Verifiable GMP Certification: Trust is earned, not given. That's why we back up our GMP certification claims with verifiable evidence. Partnering with VeriGMP®, a UL-certified company, we adhere to strict GMP quality systems, ensuring that each product meets the highest standards of manufacturing and quality assurance.

What is Niacin?

Niacin, also known as vitamin B3, is an essential nutrient that our bodies need for various metabolic processes. It plays a crucial role in converting food into energy, supporting the functioning of the nervous system, and maintaining skin health. Since our bodies cannot produce sufficient amounts of niacin, it’s important to include it in our diet or consider supplements like Niacin 500. A single 500 mg capsule provides an adequate dose of this vital vitamin, effective for many health benefits.

Health Benefits of Niacin 500

Taking Niacin 500 can offer several health benefits. It helps in improving cholesterol levels and may reduce the risk of heart disease. Furthermore, niacin has shown promise in supporting cognitive functions, enhancing mood, and promoting better blood circulation. Regular intake of niacin supplements is particularly beneficial for individuals with cholesterol issues, as it works effectively to lower LDL cholesterol while increasing HDL cholesterol.

How to Incorporate Niacin into Your Routine

Integrating Niacin 500 into your daily health regimen is simple. You can take one capsule daily, preferably with food to enhance absorption and minimize potential digestive upset. However, it's essential to consult with a healthcare professional before starting any new supplement. This is particularly important for those with existing health conditions or those taking other medications, ensuring a safe and effective integration of vitamin B3 into your diet.
