 Which are the best supplements that can quickly boost their immune system? And how should you take them if you get sick? Well let's find out. Hey friends, welcome back to my channel. My name is Greg and I'm a brain hacker creating content that will help you upgrade your brain performance. If you're interested then subscribe below and join our amazing community. Today we're going to be talking about the best supplements for boosting your immune system. I'll tell you how to take them on a daily basis to reduce the risk of getting sick. I'll also tell you how you should take them if you get sick. So if you're ready let's just begin. The first supplement I want to talk about is Vitamin C. Now Vitamin C is known for its very potent and strong antioxidant properties but also antiviral properties. Now we know that studies show that supplementing Vitamin C can definitely boost your immune system but it can also work as an antioxidant so it can fight free radicals which is very important for general health and of course for longevity. And of course supplementing Vitamin C can also decrease oxidative damage. Now you can get plenty of Vitamin C from eating vegetables, all kind of vegetables, especially kale, peppers, also sweet potatoes have a high level of Vitamin C. So if you eat a predominant plant based diet which I recommend for optimal brain performance then you're on the safe side. However, what I recently noted there are days that even though I eat extremely healthy that my Vitamin C levels are kind of a low or only low end and to boost my immune system especially in the autumn and winter when there's a flu season well maybe that's not true for the last years but in general that's when the flu comes out. I decided to supplement Vitamin C in the autumn and then in the winter as well. Now the recommand daily intake of Vitamin C is 100 to 200 milligrams per day and that's what most supplements contain. Of course you can find supplements with a much higher level of Vitamin C like this one contains about a thousand milligrams and that's the levels I take in case I get sick. So if I get a flu or if I get sick, if I have fever and so on then I take up to two thousand milligrams per day for a very short period to fight those symptoms and the severity of it. Now before you supplement very high levels of Vitamin C do consult your doctor just to be on the safe side. The next important supplement that I recommend taking for boosting your immune system is zinc. Now the cool thing about zinc is that it plays many important roles in our body especially it is important for boosting immune system but it's also important for bone growth. It's also important for brain development for eyesight etc etc. Now many studies show that supplement zinc can reduce the severity of symptoms associated with common cold or flu and can decrease the duration of those symptoms but it is very important to supplement zinc in the twenty-four hour period after you get the symptoms. That's how you can have the biggest impact on those symptoms. Now the recombined daily intake is about five milligrams to ten milligrams and the supplement I'm currently using for example contains 15 milligrams so I generally take it every two days. However if you get sick then I recommend taking a higher dose. I personally take about 75 to about 100 milligrams of zinc for a short period when I get sick. Studies show that that's the optimal dosage if you get sick to reduce the symptoms or the severity of the symptoms but of course before you supplement such a high dose you do consult your doctor.

Just before we talk about the next supplement there's an important note for you guys. If you supplement zinc, iron, magnesium and calcium make sure the total amount of all those minerals is below 800 milligrams because they use the same transporter which means that if the total amount of those minerals is about 800 milligrams then the absorption rates will decrease. So you need to be careful about that. The next supplement I want to talk about is vitamin D or in this case vitamin D3. Now vitamin D3 is crucial for general health and also for immune system. Now research shows that people who have adequate levels of vitamin D3 have enhanced immune response, decreased inflammation and are less prone to infections. Now you can get plenty of vitamin D3 through sun exposure but you need to get the sun exposure between about 10 in the morning and about 2 or 3 in the afternoon which sometimes it's really hard to do especially if you are an active professional or student whatever and you work during those hours or during the winter that's also kind of hard to get. So personally I do take an amount of 1,000 international units to 2,000 international units of vitamin D3 per day every single day. If I get sick for example then I increase this dosage to about 10,000 international units for a short period and during winter and autumn I generally take a bit higher dosage so this is about 2 to 3,000 international units per day just to be on the safe side. And then we have one of my favorite supplements for boosting immune system and this is quercetin. Now quercetin is a polyphenol a naturally occurring one that you can find in many foods such as red onions, different berries and even green tea. Now we know that quercetin has very strong antioxidant properties so it can reduce oxidative damage and fight free radicals. But recent studies show that it's a very crucial supplement to take to boost your immune system. Based on the available research, supplementing quercetin can actually prevent certain infections which is very important to know. Now the recombinant daily dosage is about 1,000 to 2,000 milligrams and that's what I supplement as well. By the way guys if you like this video please press the like button below. And then we have anacetylcystine. Now anacetylcystine is a semi essential amino acid that is sold as a supplement in certain countries but as a drug in other countries so before you consider supplementing do check the legal status where you live. Anacetylcystine is a very potent antioxidant and the recombinant daily dosage is about 600 milligrams to 1,000 to 100 milligrams per day. I don't take it that often but if I get sick or if I know that many people around me are getting flu then I do supplement in the range that I just mentioned. Alright guys that's it for this video thank you for watching don't forget to follow your inception on social media, Facebook, Instagram and so on and guys I hope to see you soon again. Stay well.
