Vitamin B3, also called niacin, is an important nutrient that helps our bodies use energy from food. It supports healthy skin, nerves, and digestion. Many people get enough niacin from their diet, but some may need extra support from supplements.
Vitamin B3 supplements come in different forms, including tablets, capsules, and extended-release options. Some are made with plain niacin, while others use niacinamide, a form that is less likely to cause flushing. It is important to choose the right kind and dose for your needs. Some supplements also include extra ingredients, so it’s a good idea to look at the label if you have allergies or want to avoid certain additives.
When buying a Vitamin B3 supplement, we pay attention to the form and strength, as well as the brand’s reputation for quality. Things like third-party testing or certifications are also good signs. This helps make sure you’re getting a safe and effective product. We spent hours researching and comparing the most popular Vitamin B3 supplements to find the ones that are worth your money.
Top Vitamin B3 (Niacin) Supplements
We have reviewed the top Vitamin B3 (Niacin) supplements to help you find the best options. Our list features high-quality choices that offer reliable support for your daily wellness routine.
Nutricost Niacinamide 500mg Capsules
This option is a good fit for people looking for a straightforward, flush-free Vitamin B3 supplement at a solid price.
Pros
- Capsules are easy to swallow and gentle on the stomach
- Avoids the common “niacin flush”
- Good value for a long-lasting supply
Cons
- Some may want a lower dosage per capsule
- Not everyone will like the unflavored taste
- No clear info about source of gelatin for strict vegetarians
It's reassuring that these capsules are easy on digestion and don't leave us with the uncomfortable “niacin flush” that can happen with other niacin supplements. We found the 500mg dose simple to fit into our daily routine, and with 240 capsules in the bottle, there's not much need to restock soon. The plain capsules make it easy to take with water and skip any strong aftertaste.
We really liked that this Nutricost product is non-GMO, gluten free, and soy free. Knowing it's made in a GMP-compliant and FDA-registered facility gives us extra peace of mind. We noticed improvements in our skin and energy levels after regular use, which matches what some doctors recommend.
One thing some of us wondered about was the source of the gelatin, which isn't clearly stated, so if you avoid animal products, it's something to keep in mind. For most needs, though, Nutricost Niacinamide 500mg Capsules gets the job done without fuss and at a fair price, which is exactly what we want from our daily supplements.
Nature’s Bounty Flush Free Niacin 500mg
We think Nature’s Bounty Flush Free Niacin is a good choice if you want a simple daily supplement without the usual niacin skin flushing.
Pros
- No skin flushing thanks to the special formula
- Small, easy-to-swallow capsules
- No artificial colors or flavors
Cons
- Not everyone may notice clear benefits
- Capsules need to be taken one or two times a day
- Some people may want higher doses
Opening the bottle, we noticed right away that there’s no strong smell. The capsules themselves are pretty small, so getting them down is easy even for people who have trouble swallowing pills. We like that they are also free from gluten and have no artificial extras.
Taking one or two capsules a day fits well into our daily routine. Since it uses a “flush free” form of niacin, we did not deal with hot flashes or redness. This is something we often see with regular niacin, so it’s a real benefit, especially for those of us who are sensitive.
Over time, we felt it helped with daily energy support. While some of us did not notice huge changes, others felt less tired. If you are looking for a gentle, no-fuss Vitamin B3 supplement, Nature’s Bounty Flush Free Niacin is a steady option with consistent results for our team.
NOW Foods Niacin 500mg Sustained Release
If we want a high-potency niacin supplement that helps with cholesterol and supports health, this is a solid pick, but we have to watch for flushing.
Pros
- Provides a strong 500 mg dose per tablet
- Sustained release helps reduce flushing side effects
- Comes from a trustworthy and long-standing brand
Cons
- Flushing or skin warmth can still happen, even with sustained release
- Tablets are larger and may be tough to swallow
- High strength may not suit everyone’s needs
When we tried NOW Foods Niacin 500mg Sustained Release, we noticed the tablets are easy to add into our daily routine with breakfast. The sustained release formula really smooths out the feelings of flushing, but we still experienced some noticeable warmth and redness, especially if we missed a dose. The effect was temporary, but it’s important to know what to expect.
We chose this product because we liked that it came from NOW Foods, a family-owned company that’s been around for decades. The bottle contains enough tablets for months, which makes it a good value if we plan to take niacin regularly.
However, the large tablet size took some getting used to and may be difficult for some people to swallow. We also found the 500 mg strength might be more than what beginners need, so it’s best to check with our doctor before starting. Overall, this niacin supplement is dependable for those seeking a strong daily dose and are okay managing occasional side effects.
Life Extension Niacin Capsules
Anyone looking for a niacin supplement with a straightforward formula and a large supply will find Life Extension Niacin Capsules to be a practical choice.
Pros
- Each bottle lasts a long time with 100 capsules
- Capsules are gluten-free and contain non-GMO ingredients
- Supports healthy cholesterol and metabolism
Cons
- Some might experience a strong flushing reaction
- Capsules are on the larger side and may be hard to swallow
- Not discontinued, but can sometimes be hard to find in stock
We noticed the 100-day supply is convenient because we don’t have to think about reordering often. These capsules also fit well with gluten-free or non-GMO dietary needs, which is great for those of us who pay attention to labels. The formula focuses on cholesterol and metabolism support, which many people seek out.
One thing we definitely experienced was the niacin flush. If you haven’t tried niacin before, the flushing sensation can be surprising or uncomfortable. It’s something you need to know about before starting. Some of us found the capsules a little large, and they may not be easy to swallow for everyone.
At times, it was a hassle to find these in stock, probably because of high demand. Even so, when we want a simple and effective niacin option, Life Extension Niacin Capsules stick out for their no-nonsense approach and reliability.
THORNE Niacinamide Capsules
For those needing a reliable, non-flushing vitamin B3, this supplement stands out for its ease of use and noticeable benefits.
Pros
- Easy to swallow capsules and gentle on the stomach
- Causes no flushing, unlike standard niacin
- Doesn't contain common allergens like gluten, dairy, or soy
Cons
- Some of us experienced minor breakouts after a few weeks
- Sleep support may vary from person to person
- Bowel changes were noticed by a few in our group
We found THORNE Niacinamide Capsules very user-friendly, especially appreciated by those who dislike the flushing side effect that often comes with niacin supplements. The capsules are smooth and don’t stick, making them simple to take every day. Many of us noticed subtle improvements in joint comfort and generally felt more rested after taking them at night.
Allergies can be a concern for many with supplements, but this product is free from gluten, dairy, and other major allergens. We liked that we didn’t have to worry about hidden ingredients. While some saw better sleep, others didn’t notice any difference, so expectations need to be realistic.
There were some downsides. A couple of us developed mild skin breakouts within two weeks, and a few had changes in bowel habits, like firmer stools. It’s best to monitor how your body reacts over the first month and adjust use if needed. Overall, we think this is a solid option for anyone searching for a gentle and effective vitamin B3 supplement.
Nutricost Niacin 100mg Capsules
Anyone who wants a simple and reliable niacin supplement should consider Nutricost Niacin 100mg for its easy-to-manage dose and straightforward formula.
Pros
- Distributes an easy-to-control 100mg dose per capsule
- Provides good value with 240 capsules per bottle
- Made in a facility that follows strict testing and safety standards
Cons
- Causes a noticeable niacin flush for most people
- Taking it on an empty stomach increases flushing
- Not ideal for those who dislike that flushed feeling
Taking Nutricost Niacin 100mg capsules, we found the immediate release formula worked quickly. The warming and tingling “niacin flush” happened within 30 minutes after swallowing a capsule, especially if we hadn’t eaten much beforehand. This flush can be uncomfortable for some people, but eating with a full meal helped tone down the effect.
We liked that the capsules were small and easy to take. A single 100mg dose felt more manageable than higher-dose tablets, and we could adjust our intake as needed. The no-nonsense, gluten-free formula was a plus. We noticed no odd aftertaste, and the capsules did not upset our stomachs.
Since these capsules are made in a facility that tests for quality, we felt confident using them for our daily supplement needs. For people sensitive to the flushing, this may not be the best pick, but if we wanted the classic niacin effect, this supplement delivered every time.
Nutricost Niacin 500mg Capsules
If we want a strong niacin dose and don’t mind dealing with a very noticeable flush, Nutricost Niacin delivers noticeable effects.
Pros
- High 500mg strength per capsule helps us meet daily needs
- Large bottle with 240 easy-to-take capsules
- Clear labelling of potential flush so we know what to expect
Cons
- Niacin flush is common with this product and can be uncomfortable
- Best taken with food, or it may cause stomach discomfort
- Contains processing ingredients some people try to avoid
After trying Nutricost Niacin, we noticed a powerful warming flush that kicked in about 30 minutes after swallowing a capsule. The bottle directly warns us about this common side effect, so we weren’t surprised. If we take the supplement with a meal and some water, the flush seems to settle faster.
We liked how each capsule gives a clear 500mg dose, and the bottle lasts a long time since it comes with 240 capsules. It’s simple to take, and the capsules are not too large, making them easier to swallow for us.
This isn’t the best choice for anyone sensitive to the niacin flush or who dislikes a tingling, warming feeling in their skin. For people wanting the “non-flush” form, Nutricost does remind us to pick another version. Overall, if we can handle the flush and want a high-potency supplement, this bottle offers solid value.
Endur-Acin Extended Release Niacin by Endurance Products
This is a smart pick if we want gentle, extended-release niacin tablets that are straightforward and easy on the stomach.
Pros
- Gentle, extended-release formula with less flushing
- Simple tablets that are easy to swallow
- No harsh additives; suits several diets
Cons
- Occasional mild flushing still possible
- Tablet coating can be slightly waxy
- Some containers may arrive with dented lids
Taking Endur-Acin Extended Release Niacin feels very smooth compared to regular niacin. The gradual release means we do not get that sudden, uncomfortable flush that sometimes turns people off vitamin B3. We noticed the tablets were easy to take with water, and there was no strange aftertaste.
We appreciate that this product is made to fit many dietary needs. Since it is gluten-free and vegan, almost anyone in our group can use it. Having a lower risk of harsh side effects makes it more comfortable to stick with long-term.
On the downside, a slight flush can still happen, especially if we take it on an empty stomach. The tablets have a waxy layer that may feel a bit odd at first, and we’ve seen that sometimes the bottle arrives with a misshapen or dented cap. Still, for daily use and gentle absorption, Endur-Acin stands out for its gentle, balanced formula.

NOW Flush-Free Niacin is a solid pick for those who want vitamin B3 without the annoying flush.
Pros
- No niacin flush, even with regular use
- Easy to add to our daily routine
- Budget-friendly for a 90-capsule bottle
Cons
- Occasional capsule is a bit large
- No noticeable impact on sleep or skin for some of us
- Simple packaging, not the most attractive
After taking these capsules for a while, we did not experience the usual flushing that comes with standard niacin. This made it much more comfortable to stick with a daily routine. The flush-free label held true in our case, so we felt at ease whether using it for cholesterol or general health.
Each capsule was easy enough to add to our morning supplement stack, though a few of us found the size a little big. If you have issues with larger capsules, that is something to think about. Most of us appreciated the value—90 capsules per bottle at a fair price means we weren’t constantly reordering.
While we did not notice a big difference in our sleep or skin, our main goal was to avoid the flush, and NOW's formula delivered here. The packaging is basic but functional. We found this supplement to be reliable, gentle on our stomachs, and simple to work into our routines. If you want a no-flush niacin that covers the basics, we think NOW Flush-Free Niacin is worth a try.
Deal Supplement Vitamin B3 Nicotinamide
This is a solid pick for anyone who wants a high-dose, flush-free B3 supplement that's easy to fit into a daily routine.
Pros
- No flushing or itching side effects
- Large bottle offers long-term supply
- Easy to add to drinks or swallow
Cons
- Big capsules may be tricky for some
- Some users report a strong reaction to high doses
- Not the cheapest option available
We found that this Deal Supplement Vitamin B3 Nicotinamide is especially convenient because it’s flush free, so we don’t have to worry about red or itchy skin. The capsules are filled with a fine white powder, and they work equally well whether we swallow them or mix them into a drink. This flexibility makes it easy to use daily, no matter our habits.
The bottle is generous, giving enough capsules to last about eight months if we follow the suggested serving. That means less time shopping and more consistency in our routine. We noticed that the product is gentle on our stomachs, and it’s free from most common allergens.
There are a few drawbacks. The capsules are a little large, so they may be difficult for some of us to swallow. At higher doses, a few people seem to react strongly, so we always start with a smaller amount before increasing. Although it’s not the most budget-friendly on the market, the long supply does add value over time.
