Get someone healthy with lower blood pressure with better food and lifestyle choices then add in "good salt" and they'll not have any problems. We need salt (not table salt tho lol).
Excess sodium displaces magnesium in cells, causing a shift to higher plasma volume (high blood pressure)
In western soceity it's more a case of excess sodium + not enough magnesium + low renal function (for various reasons) = high blood pressure (there are many other factors such as vassopressin, ADH / general adrenal and kidney disfunction)
A lot of people actually get away with a high sodium intake (as is normal on western diets).
A higher sodium (and eletrolyte mineral generally) intake is recommended for hard training athletes, still the 6g of salt is more than enough to cover everyone. (excluding severe renal disfunction)
As far as supplementing with salts, basically the positioning of sea salt above processed salt is correct, providing you are getting enough iodine in your diet (as refined cooking salt is iodised) because it contains magnesium, and some in sulphate form. (+ a tiny bit of calcium and a few trace minerals)
'himalayan' salt is not anything better than most rock salts, all a product of dried out high salinty sea/lake beds, the mineral composition is often very similar, don't waste your money on any cons that claim it to be the elixer of youth or whatever.
Now, it depends what you want from a salt product for cooking or supplementation to make your choice.
Sea salt is great for cooking due to better flavour than processed salts but if you are using it as a health supplement then you will mostly be obtaining sodium chloride, the few percent of other minerals are not high enough to be considered beneficial in the doses you are taking.
A relatively minor (7%) constituant of sea water is magnesium chloride (providing 3.7% elemental magnesium), magnesium has massive benefits for health and athletic peformance, it is a vital electrolyte that many people are deficient in, whereas they have more than enough sodium (as discussed above), thankfully you can actually buy fractioned magnesium chloride (with a percentage omagnesium sulphate and trace elements) known under the japanese name 'nigari' (they use it traditionally for coagulating the tofu proteins) i will mention where you can buy this bulk, cheaply if anyone is interested.
The other electrolyte people have as lack of is potassium, the salt of potassium, potassium chloride can be obtained from 'low sodium' salts, there is one called 'salt rite' (or something like that) that is almost 100% potassium chloride.
Now, there are some issues with obtaining all of your electrolytic minerals as chloride salts, you don't really want to exceed 4000-5000mg of chloride a day.
Therefore, taking into account sodium, magnesium and potassium intakes from the average diet i would recommend a salt/electrolyte supplementation regime of :
-1000mg sodium chloride (just use sea salt)
-2000mg magnesium chloride 'nigari'
-2000mg potassium chloride (use 'salt rite' etc as described above)
Mix in water and drink throughout the day, obviously this produces a salty and somewhat bitter (due to MgCl) taste, so it will need to be diluted over 1 or 2 litres of water.
Remember, this will not provide the ideal amount of potassium or sodium for the day, ideally you want most of your potassium from fruit and vegetables (tomatoes, avocaodo, bananas etc) as these are in the form of bicarbonates, sulphates, organic compounds etc.
Sodium will come easy in almost all diets unless you are extremely restricting yourself and not eating any 'modern' foods or seasoning your meals with salt etc.
Magnesium supplementation is the most important on a 'good diet' as foods available and commonly eating do not provide particularly large values, especially in light of high sodium intakes and phytic acid intake (which binds to magnesium in the gut, preventing uptake)
As far as 'trace elements' in these salt products you buy, not really worth noting, as the dose of salt is so low that the small percentage of mineral (depiste being a low rda in the case of iodine, selenium etc) becomes irrelevant.
It is the macromineral (electrolytic) concentrations that you should be intereted in.
Remember these are:
-Calcium
-Magnesium
-Phosphorus
-Sodium
-Potassium
-Chloride
Calcium and phosphorus, not mentioned in salt supplementation are best aquired from dairy, seafood (with bones ideally...sprats are great) etc, vitamin D helps their absorption massively.
Trace elements can be obtained from other foods, i.e iodine from kelp, seafood... selenium from brazil nuts, seafood, pork....copper from liver, zinc from meat and seafood (i can go into this if you want but it's relatively common knowledge)
As far as any 'alkaline' properties of 'special salts' over normal salts, it is untrue, remember which ions form acid and alkaline solutions in water, the key is bicarbonate control in the body (and why vegetable intake is recommended) the body is more than capable of maintaining ph homeostasis, the idea of alkaline diets is to take stress of the body in doing so.
