I have a recent supplement eye opening experience to share.
I am 32 years old, I have hypertension. I have had (or at least know about) said hypertension since I was in my early to mid 20's. My average blood pressures were 150's/160's over 95/105. Worst blood pressure I recorded was 165/110.
I'm a fairly healthy guy, I've been active and exercised fairly regular the majority of my life. Several years ago after a health fair at work where the above 165/110 reading was recorded, I decided to the Dr. about it. I was told that they weren't sure the root cause, they said it probably just runs in my family but that there was no known root for the cause because overall I'm a fairly healthy guy. They started me on blood pressure meds, they put me on metoprolol. I have been on this for about 3 years and it has kept my blood pressure around 125-130 over 87/90 range. Still not amazing, but much better than it was.
Recently like many others I have started listening to guys like Huberman etc. One guy I have come to really enjoy, is Gary Brecka. In one of his videos, he talks about people who have hypertension, but the Dr.s cant explain a reason for it, just blame it on genetics and put patient on blood pressure meds, which attack the heart, but the heart is doing nothing wrong. My takeaway was that the blood pressure meds are just a band aid to get the blood pressure to an acceptable range, but you haven't cured the root of the issue.
His recommendation was to try a supplement, an amino acid called TMG (Trimethyglycine). He offered an explanation for why this works that I wont go deep into, but I will put a link to the video you can watch for yourself if you are interested.
Either way, I was very skeptical. I figured what the hell, I'll order a bottle off amazon and give it a try. Worst thing that could happen is my blood pressure starts to climb back up and I get back on my prescription.
It has been just over a month now, I take 1,000mg (2 pills) of TMG a day. My blood pressures are the best they have ever been since I can recall, better than they were on my prescription. I have been averaging 118/120 over 75-82. These blood pressures have maintained for a little over a month now. I kind of expected them to start creeping back up, but so far they seem to be holding steady.
I certainly think there is a ton of snake oil type supplements on the market. But I am now a believer that if your body is deficient in certain things, that there is incredible benefit to figuring out and supplementing those particular deficiencies.
Here is a link to the video clip of him explaining the supplement & science for anyone who is interested. There is a longer clip out there somewhere but I couldn't find it. This gives you the idea though.
