Beta Alanine and Heart Palpitations?


#1

I did a google search and some of what I immediately came up with was some people saying they think they associate beta alanine with heart palpitations, and a medical related site that indicated there was no known correlation.

The story with me is that I read over New Year’s that most people aren’t taking enough beta alanine, the amounts in preworkouts are not enough to do much good. I then bought a free standing supply of it and decided that I would supplement my preworkout such that I was getting about a teaspoon each day, 3.2g. Of course I would take it on non workout days as well, totaling the same amount.

With no other factors different, I am taking the same other preworkouts in the same doses, the same amount of caffeine each day, and creatine monohydrate. I have noticed heart palpitations since the beginning of January.

I am collecting experience from people to confirm the likelihood of what I am thinking. If so, how scared should I be?

Aren’t heart palpitations the kind of thing you see a doctor for? I’ve been taking beta alanine for about a year and a half almost every day and I haven’t noticed anything. Could be because I’ve gradually been increasing my dosage (up to ~4.5g from ~2g when I first started), or because I’m just not self-aware enough.

I haven’t heard anything about beta alanine being bad for you, but I’m interested to see if anyone else has had those symptoms. I might have to reevaluate what I’m using.

I’ve been taking the same dosage and drink a lot of coffee and have not had any heart issues.

Yes, I know it is a doctor visit sort of thing, I wanted to cover this possibility first. Maybe it is inconsistent in its overall effects on people. One thing I will note is that I had palpitations on Sunday, when last I had taken a preworkout on Friday, but was still using Beta alanine every day. I started having this issue in correlation to upping my beta alanine intake.

I will wait for more responses before I decide what to do.

PersonallyI would just stop using it then loads of other supps out there to give your workouts a boost. Citrulline malate comes to mind.
Some other thought: if do keep taking it only need it preworkout, waste of money to have on off days

taking preworkout with a bunch of stims every session is not great for you either -can lead to raised blood pressure and minor heart issues like palpatation feelings, also lead to feeling burnt out and even stress the adrenals. best take just once a week and the other days just get caffeine

As to stimulants, i am relying on a one hour window after the end of breakfast coffee (breakfast/preworkout meal) before I take let’s say a 3/4 scoop of Mr. Hyde, amounting to 300 mg of caffeine just there. I have done such a thing for several years, and it is scary to contemplate if maybe I have gone down a cumulative road with it to reach what I notice now. So part of my immediate plan is to scale back caffeine intake, basically the coffee on the same day as a preworkout formula.

As I am noticing this event since using beta alanine above preworkout formulas (one or another on any given workout day) I will immediately cut that out, and see.

I don’t know if it is relevant, but I was flying high with my training this past 5 or 6 weeks, and a week and a half ago noticed a sharp drop in my energy level, I barely wanted to get out of bed. I noticed a sharp drop off in performance so I took most of last week off, maybe it made sense anyway, I may have lost track of time drilling away at it. Friday and today I went at it sub par.

So going forward I will when I actually feel a good energy level exercise without extra beta alanine and reduced caffeine and see over the next few days how things seem.

of courses, it can’t be the Cafeine who create heart palpitations, you just take 1 preworkout per day + some coffee…this is nothing LOL

I am actually waking up to being more reasonable with the caffeine. It is just that I had been doing the same thing for the longest time and it is only in the month and a bit that I added extra beta alanine that I noticed the palpitations, different people might not have the same experience.

As more of an update, I stopped taking the higher daily amount of beta alanine after this past Sunday, I took a 3/4 scoop of Mr. Hyde preworkout (Canadian formula) on each of Monday and Tuesday that gave me about 1.85 g of BA each time, and on Wednesday took a sampler of an intraworkout that is more like a pre with 1.5g. today none of the above. I have noticed a sharp drop off to the point I don’t have palpitations, so I am convinced of what I thought.

Beyond that I have over the last couple of weeks noticed a sharp drop off in exercise performance and waking up tired. Since i have a muscular strain in my left forearm, I am restricting myself to an aerobics routine that is partly calisthenic that doesn’t aggravate it. I was doing this 4 times per week for a while and I wonder if I just have to program more rest or this is a related issue.
