I recently did a comprehensive vitamins and minerals test. Everything was fine, except for low sodium (2532 while range is 2900 - 3335). Interestingly, the last time I took the test in 2009 it was the same. However, results of my regular electrolytes blood test (Ca, K, Mg, Na) are fine which makes me wonder how is it possible?
I generally eat a significant amount of salt (go with a taste, don't artificially try to increase/decrease it). I also have a borderline blood pressure (almost 130-140 / 80-90), so it would probably not be a good idea to artificially try to increase sodium consumption even more.
Any thoughts are very welcome! Thank you!

Serum sodium is homeostatic. Your body can be low on sodium while serum sodium is normal.
If you eat less than 60 grams of carbohydrate daily you'll need a couple extra grams of sodium daily. Potassium will need supplemented as well, most likely.
Consider a daily broth with added sea salt (1/2 tsp) and potassium gluconate (1 tsp). After a week or so, you should see BP come down and your strength increase.
