Good to know

Niacin (nicotinic acid) may cause temporary flushing — warmth, redness, tingling, or itching of the skin. This is a normal, well-known reaction and generally subsides on its own. Food supplements aren’t a substitute for a varied, balanced diet. If you’re pregnant, breastfeeding, on medication, or managing a health condition, check with a healthcare professional before use.

Description

MB Superfoods Niacin (Vitamin B3) – 100mg, 100 Tablets

A no-frills Vitamin B3 supplement, built for people who want a reliable daily addition without extra fillers or complicated formulas. Each tablet delivers 100mg of niacin in its nicotinic acid form, contributing to normal energy-yielding metabolism, normal nervous system function, and the reduction of tiredness and fatigue.

What’s in Every Tablet

100mg of niacin (Vitamin B3), as nicotinic acid — the form most commonly associated with the “niacin flush” (more on that below). Vitamin B3 plays a role in how your body converts food into usable energy and supports normal functioning of the nervous system. 100 tablets per bottle, so one bottle covers a solid daily supply.

Vegan, and Free from the Usual Fillers

No gluten, no lactose, no GMOs, and suitable for vegans. If you’re building a supplement routine and want to keep unnecessary additives out of it, this fits that approach.

Why Niacin, and Why Alongside a Mushroom Stack?

Niacin is often paired with functional mushroom powders — Lion’s Mane in particular — as part of a broader daily stack. We’re not going to claim niacin boosts absorption of other supplements or has effects beyond its established role in energy metabolism and nervous system function; that’s not something we can back with evidence. What we can say is it’s a common, well-understood addition for people already taking mushroom extracts who want a straightforward B3 source to go with it.

About the Niacin Flush

Nicotinic acid can cause a temporary reaction — warmth, redness, tingling, or itching of the skin, sometimes called the “niacin flush.” It’s a well-documented, generally harmless response and tends to fade on its own within 20–30 minutes. If you’re new to niacin, just be aware the flush can happen, especially the first few times you take it — it’s not a sign anything’s wrong.

Often Purchased Alongside

🍄 Lion’s Mane Mushroom Powder (100g) — a common pairing for people building a daily mushroom + B3 routine
🌿 McMicrodose Starter Kit (5x 1g Kits) — for those exploring a broader stack

Good to Know

Food supplements aren’t a substitute for a varied, balanced diet and healthy lifestyle. If you’re pregnant, breastfeeding, on medication, or managing a health condition, check with a healthcare professional before starting. Store in a cool, dry place, and keep out of reach of children.

    I’ve just purchased this amazing product with Niacin capsules. To be honest I can’t wait to start my journey .
    Thanks

    Een klein tabletje en 5 minuten later, een flinke flush, opvlieger. Rood gezicht,hals,armen,enz. Eerste 5 dagen niet prettig te noemen, maar dat vermindert en wat je er voor terug krijgt is zeer fijn te noemen: Meer energie, warme handen en voeten, mooie zachte huid, vermindering van [spanning in het hoofd], dit al na gebruik van 2 weken 3x per dag een tablet van 100 mg. Dus zeker de moeite waard.

    Niacin has greatly improved my life. My depressive thoughts disappeared from the start (500mg a day now for 2 weeks, now going up to 1000mg a day). My girlfriend has also been taking it, and we’ve both been in a greater mood (she’s also depressive). Suicidal thoughts are rare now. I no longer flush.

    I recently watched the movie Food Matters and learned that Niacin could be used to treat depression and alcoholism in addition to high cholesterol. I began taking it last week and have noticed a gradual improvement in my mood as I increase the dosage. Make sure you start low and increase gradually, though: the first time I took it, I took 100mg with a light snack and ended up stripping down and standing in my kitchen painting, but there were no lasting negative effects.

    This niacin seems like a magical drug, and the best part is it’s not a drug…it’s a vitamin!!!

    It helps me with sleep. I now take the same brand, but 500mg helps me tremendously and helps me wean off my sleep med! Won’t go without Niacin.
    Thank you Bros store

    Feel the burn, baby! I pop one of these babies in the morning on an empty stomach, and about 20 minutes later, my face feels sunburnt, my skin begins to itch, and my body radiates like the sun. I love it because I know it’s working! It will fade in about 15 minutes so ride it out. You’ll be ok, sissy.
    I am using niacin to help lower triglycerides and bad cholesterol. I will report back in a couple of months with bloodwork results from my doc. For most supplements, you hope to do something when you take them. You can feel these getting to work!

    Highly recommend this micro dosing with Microdose Bros, 10 of 10!

    I had slightly elevated cholesterol but didn’t want to take statins. My PCP recommended 1200mg of niacin (yes, the nasty full-flush kind, the flush does lessen with time). For years I have suffered from depression. Antidepressants made me feel worse. That dark, heavy cloud on my brain just went away by the second day of taking niacin.

    nadat ik 3 jaar geleden ten gevolge van een herseninfarct halfzijdig verlamd ben geworden kreeg ik een tip om niacin 100 mg te gebruiken om de kans op gedeeltelijk herstel te vergroten. ik merk na het gebruik van niacin 100 mg enige verbetering, zo bleek het ineens mogelijk om met twee handen (inclusief de verlamde kant) aan het stuur te fietsen, voor het eerst in drie jaar

    Ik vind het jammer dat de twee onderstaande reageerders dit product 1 ster geven. Dit is gewoon onzinnige beoordeling want niacin heeft altijd een flush. Wanneer je geen flush wilde had je maar de non-flush moeten kopen. Dit product is gewoon van perfecte kwaliteit en een aanrader!

    I am amazed by the mental effects of Niacin. OK, I started taking it five weeks ago to lower my high cholesterol and Triglycerides off the chart!!! I have been having energy as I had 20 years ago, a positive attitude, and motivation.

    een flush bij gebruik van niacin is normaal en vind ik zelf niet echt onaangenaam. Kan me voorstellen dat iemand er van schrikt als je het niet verwacht. Is in elk geval niet schadelijk of zo. Overigens hangt de sterkte van de flush nogal af van de maaginhoud; vlak na de maaltijd merk ik niet veel. Maar je gebruikt het niet vanwege de flush, voor de rest is het een prima product voor zover ik dat beoordelen kan….. Een overdosering van 15 x (1500mg per dag)lijkt me wel een beetje erg veel trouwens

    Ik had last van een ongename flush, het voelde alsof ik erg verbrand was door de zon. Het is beter om een half uur van te voren een paracetamol in te nemen, die de bijwerkingen van de flush remt.

    Ik gebruik niacine dagelijks voor de aanvulling van vitamine B3. Bevalt me goed. Goede en snelle levering.
