Take With Caution

Опубликовано Krisinsight янв 23, 2015 | Проверенная покупка

I received my iherb order yesterday and decided to try the Niacin from Life Extension I had ordered. I wisely dumped half of the capsule out before popping it in my mouth because I have experienced Niacin flushes before. Nothing happened for about 30 minutes. Since I was feeling okay I then had a cup of hot herbal tea. The flush came on with a bang starting with my face, my neck, my arms and then legs. Then my heart started beating rapidly and my tongue felt slightly swollen and my mouth dried out. I had the most severe chills (due to heat in my body from the flush) I have ever experienced but I knew I needed to drink water to flush the flush, so with shaking hands I drank water and lots of it. I think about two hours later it was over. I started researching the dose of 500 mg. On every site I went to 250 mg was considered a high dose and possibly an overdose. Now I wonder why almost everyone in the reviews think that 500 mg is a good dose to take and I see that LE sells a 1000 mg dose capsule as well. My conclusion: Taking a high dose Niacin is not for me (perhaps the fact that I take thyroid meds accentuate the flush and chills). If I take it again I will not follow up with hot tea and I will only take a very small portion of the capsule.

The first 3 times I took this product I produced a really bad rash, I was very red and hot all over, the fourth was a little better, but I have not taken it since

10分ほどでフラッシュが来て首顔が暑いと思っていたら腕や足まで痒くなり 30分くらいで全身寒気に変わりました。 あんまり合わなかもしれないと思いました それから2日後足に蕁麻疹と浮腫みが出て痒くて3日ほど搔きむしりました。つらい足はパンパンで 市販薬レスタミンを飲みましたがなかなか治らなくて私には量が多かったようです。 50キロです 皆さんも最初は少なくスタートをお勧めします
