Nutricost Niacin (Vitamin B3) Powder 250 Grams, May Cause Flush

This goes into my lemon water every morning. I only use about 1/8 of a teaspoon, as my skin is a bit sensitive, and flushes more easily than most. I will tell you, 1/8 tsp is PLENTY. I'm not sure where they got the "1 scoop = 1 serving, but that is way overkill. My dosage has done wonders for my cholesterol levels, and I'm sure my heart is thankful for it. It's great to add into your gym drink, or just your workday water bottle. Niacin does provide healthy energy production benefits, as an added bonus. If you're skin flushes and burns with niacin, I recommend taking it before bed. The flushing will be gone when you wake up, and you'll never even know it warmed you up while you slept! This is a ridiculous bargain compared to buying capsules. If you're only taking the normal recommended dosage for adults per day (100%), this one jar will literally last years.

Bought this to use on my ducklings and it works great but only used half the scoop

This is a very potent supplement. I took one scoop the first time (recommended dosage) and the flush was horrendous. Most B complex supplements contain about 20 mg of Niacin. Nutricost recommends 1g per serving, which is about 50 times more than what is in a regular B complex pill. This is why I was literally burning when I took it, and could feel my heart pounding in my ears. I turned red like a lobster and the itching in arms and legs was intolerable. This lasted for about 2 hours. I took a cold shower hopping it goes away, and it did not. I was at a point I almost called 911. The only thing that worked was flushing it out by drinking about 64 oz of water. I am giving it 5 stars because the product is high quality. However, it believe Nutracost should include a note in the label suggesting to start with perhaps 1/4 of a scoop and work you way up until a comfortable tolerance level is reached.

Start with very small doses. This product creates crazy hot flushes. Depending on your sensitivity, you may break out into hives-like splotches on the skin, which will subside after a number of hours. For severe cases, cold showers, drink tonnes of water, splash with chilled chamomile tea. Or just avoid all that and start with minute doses and work your way up until you know your tolerance. I take this for protein synthesis, so it's not immediately apparent if it's working, especially as it's part of my supplement stack. But, as niacin is know to flush, I guessing that it's doing its job.

I like that this is pure. I was looking for the very best deal on pure Niacin. The real stuff that can sometimes give you flushing (so you know it's working). This is the real deal! So happy with my purchase. If you want perhaps the most important vitamin for longevity and cholesterol control this is it (Though Pantothenic Acid is also up there). Very Happy with my purchase. I can mix a little into my smoothy. The little scooper is for 1 gram, but it has a half mark if you only want to take 500 mg. Great product, exactly as advertised ans so essential for your health! If you are sensitive to flushing this may make you flush (depending on how many MG you take, but that's how you know it's recharging your mitochondria and making NADH. One of the only vitamins you actually feel working.

Saved my ducks. I used this for my Muscovy ducklings and judging by their buff legs…it works extremely well. At first, I tried the brewer’s yeast (which was recommended) for poultry on Amazon for about three weeks but the niacin inside was like 2% and just not enough to be even useful - ducks need a lot of niacin or else they have trouble walking and fail to thrive which unfortunately happened in my case. So, I switched to this product and the difference was immediate within 48 hours all three were able to bounce back and walk properly. I would recommend using this nutricost niacin because the results can easily be seen and achieved compared to the other products that only contain small bits of niacin.

Totally disappointed with Nutricost Niacin Vitamin B3 Powder 250 Grams. Was excited to get it - until - I tried mixing it. Of 1 whole scoop of powder around 1/8th would NOT dissolve even though I was using an electric blender/stir stick. Before blending - and just by merely dumping a scoopful into room temp water - bigger chunks of powder floated on top while smaller powder granules sank to the bottom. Then I blended for a good 30 seconds - then another 30 seconds - and yet - a whole bunch of white powder was still gathered in the middle - at the bottom of the glass. A bit disturbing. What is that stuff? Ran it through a paper coffee filter to strain out all the non-dissolved white powder - which was a LOT!!! Next I called Nutricost (phone number on side of cannister). Call was answered immediately. Explained the problem. Asked why at least 1/8th of the powder would not dissolve even when using an electric stir stick. Here's what I was told (aka - Jump Through Hoops) Nutricost Customer Service: "You need to send Nutricost an email with the Receipt and Pictures attached - along with the Lot Number - then we'll be able to answer your question". I told her I wasn't looking for my money back. Just wanted to know why the powder was not dissolving. She simply repeated herself with what she said above. Got off the phone. Tossed it in the garbage and ordered from another company outside of Amazon who promised me their Niacin (Nicotinic Acid - gives you the Flush) would certainly dissolve without problem, and was also 3rd party tested. Ended up opening an account with them and spent extra money on some of their other supplements as well. My honest opinion. Don't waste your money on Nutricost Niacin UNLESS you don't mind a mouth full of grit from all the non-dissolved powder every time you mix a scoop full. I've also had the same problem of non-dissolving Niacin from Solgar, Bulk Supplements and another place I can't remember. Perhaps they all buy their Niacin from the same supplier. Sorry - but since I haven't received the Niacin from the other company yet which I just ordered from - I can't give a review on it. I have a feeling though, from what that company told me - I will have no problem with their Niacin.

Vitamin B3 Ir Niacin as listed the advantages of powdered supplements at my age is a plus so measured amounts are under my control,. Most over the age 50 lack credibility with body support of original health up to an age where are lab reports show a difference where supplements can help

コスパ最強、飲み過ぎ注意

I knew a bit the effect from others, like burning, itchy sensation etc, but hadn't experienced it by myself. I took 1 scoop at the first time, after around 10 minutes, I felt something weird on my neck and my upper arm, I thought I got stroke. I now understand the sensation of flushing. I notice my blood pressure become lower. I notice small white particle that hard to dissolve, I agree with other people opinion. But when I use warm water, the white particle disappear very quick. I prefer to take it before going to bed, I feel warm and can sleep tight.

Excellent produit

Be careful of side effects, it caused me a blood in stool and inconvenient feeling

1匙1000mgですが、ほとんどの日本人には多すぎます。 1回の接種は200mg程度で丁度良いかと。 1000mg飲んだら肝機能不全になり、救急搬送されてしまいました。 ご利用は計画的に。
