Betaine HCL Works – pH Meter Photo Proof
There are people who claim that Betaine HCL is just a useless supplement since it does not lower the pH of the stomach.
Sure it does lower the pH and significantly enough for activation of the protein digesting enzymes!
Betaine HCL is actually one of the best selling supplements for digestion. Basically it is just a hydrochloric acid (HCL) molecule bound to Betaine (trimethylglycine – TMG) molecule. This combo forms a salt – Betaine HCL – that you take in capsules. After the capsules dissolve in stomach the HCL and Betaine bonds are broken down and free HCL molecules lowers the stomach pH.
But how many capsules do you need to take and still not wasting the money by “eating” too many capsules with every meal in order to bring the stomach pH levels down enough?
To answer this question we need to find out how much fluid holds the stomach.
The answer is 30 – 100 ml and the pH of the fluid is about 1.5 – 3.5. Many doctors think that pH 2.0 or higher is too high in order to digest the food properly so it is debatable if it is still a healthy person who have the pH of the stomach higher than 2.0 or 2.5.
That’s why you should not drink water shortly before or after eating – you will dilute stomach acid and negatively affect the digestive process.
The product that was used in this test is the Betaine HCL from NOW. The iHerb.com sells this supplement for about 13 USD.
How much betaine and hydrochloric acid is in one Betaine HCL capsule?
650 mg (0.65g) – is the common size of one Betaine HCL capsule
153,61 g/mol – molecular weight of Betaine HCL
36,46 g/mol – molecular weight of HCL
117,15 g/mol – molecular weight of Betaine
You can calculate the content of HCL in Betaine HCL like this:
0.65 g / 153,61 g/mol = 0.004231 mol
0.004231 mol x 36,46 g/mol = 0.154 g of HCL
153,61 (g/mol) / 36,46 (g/mol) = 4.213
0.65 g / 4.213 = 0.154 g of HCL
That means you get 0.154 gram or 154 mg of hydrochloric acid from one 650 mg capsule of Betaine HCL.
Betaine HCL capsules – HCL content
1 capsule of Betaine HCL = 0.154 g of HCL
2 capsules of Betaine HCL = 0.308 g of HCL
3 capsules of Betaine HCL = 0.462 g of HCL
4 capsules of Betaine HCL = 0.616 g of HCL
5 capsules of Betaine HCL = 0.770 g of HCL
6 capsules of Betaine HCL = 0.924 g of HCL
7 capsules of Betaine HCL = 1.078 g of HCL
How to calculate the pH of the solution?
Amount of HCL (mol) = Weight of HCL (grams) / molecular weight of HCL (36.46 grams/mol)
Concentration (mol/Litre) = HCL (mol) / solution volume (Litre)
pH = – log (Concentration)
Betaine HCL in 100ml (3.3 fl. oz) of water
Amount of HCL (mol) = 0.154g / 36.46 g/mol = 0.00422 mol
Concentration = 0.00422 mol / 0.100 L = 0.0422 mol/L
pH = -log (0.0422 mol/L) = 1.37
Amount of HCL (mol) = 0.308g / 36.46 g/mol = 0.00844 mol
Concentration = 0.00844 mol / 0.100 L = 0.0844 mol/L
pH = -log (0.0844 mol/L) = 1.07
Amount of HCL (mol) = 0.462g / 36.46 g/mol = 0.01267 mol
Concentration = 0.01267 mol / 0.100 L = 0.1267 mol/L
pH = -log (0.1267 mol/L) = 0.89
Amount of HCL (mol) = 0.616g / 36.46 g/mol = 0.01689 mol
Concentration = 0.01689 mol / 0.100 L = 0.1689 mol/L
pH = -log (0.1689 mol/L) = 0.77
Amount of HCL (mol) = 0.770g / 36.46 g/mol = 0.02111 mol
Concentration = 0.02111 mol / 0.100 L = 0.2111 mol/L
pH = -log (0.2111 mol/L) = 0.67
Amount of HCL (mol) = 0.924g /
