amino acid supplement side effects lumity anti aging

Last month I was gifted the Lumity Anti-Aging Nutraceutical Dietary Supplement kit. Each kit includes 84 morning soft gels and 84 nighttime soft gels. The instructions say to take three pills in the morning and three pills in the evening.

I reviewed the ingredients, like I normally do with supplements, and everything looked good: Flax seed oil, vitamins, trace minerals and the Lumity Renew Complex and the Lumity Vita Complex; both made up of amino acids. 

After one week of taking the supplements, I started to experience nausea, lightheadedness, and extreme fatigue in the mornings until midday. One night I even woke up with my heart racing and insomnia. I had changed nothing in my lifestyle except for the Lumity supplements, so I knew they had to be the cause. But I thought, aren’t amino acids healthy and good? Why would these cause negative side effects?

The simple answer: good things in excess can sometimes be bad.

I am in no way representing that I am a nutrition expert, but based on online research I found, in particular a study published in 2004 in The Journal of Nutrition titled The Nature Of Human Hazards Associated With Excessive Intake of Amino Acids, it appears certain amino acids in excess can cause negative side effects.

When I broke down the ingredients, here’s what I found…

I follow a paleo-ish, high protein diet, and after researching these amino acids it was clear I was getting excess amounts for my body causing my upset stomach, nausea, dizziness and extreme fatigue. I also have naturally low blood pressure that falls consistently around 94/60, so perhaps, the fact that Coenzyme Q10 and L-Arginine can cause increased low blood pressure may have played a role in my experience. 

Finally, everyone is going to have a different response to supplements since we all need different requirements, but if you eat a paleo/whole-30/high-protein diet, I would recommend treading lightly with these and speaking to your medical professional before taking (which is what we all should be doing with any supplement…).
