Learn about the features of each raw material we use!
Betaine HCl
Our product provide a daily dose of 1311,2 mg of Betaine HCl; in just 1 intake.
The 'base' betaine content is approximately 76% of the betaine hydrochloride form, and this amount is broken down on the product labelling to give you a precise indication of the substance of interest's content.
Other companies on the market sell the Betaine HCl form as if it’s the base betaine amount, which it’s not, meaning they’re providing misleading information to consumers who believe they're using almost 25% more pure betaine than they actually are.
At HSN, we work with maximum transparency.
Protease
Protease is an enzyme.
The activity per gram of our raw material is 450000 HUT/g (Hemoglobin Unit Tyrosine per gram).
The recommended daily amount of our product provides 113,4mg of protease, which is equivalent to a net activity of 54000HUT per serving.
Chloride
Betaine HCl 650mg is a source of chloride, providing 120mg.
The form used is potassium chloride, a mineral salt authorised for the previously declared digestive effects of chloride. The sodium chloride form does not have this property attributed to it.
At HSN, we pay attention to every last detail to ensure the development of our in-house formulas is of the highest quality, with all the guarantees.
Vegan-friendly
Betaine HCl 650mg Complex is a product suitable for vegetarian and vegan diets.

Best before lunch
Sara 28/08/2025
Betaine is an active ingredient used to create acidity in the stomach for better digestion. It should be taken before eating. I recommend before lunch, not breakfast. Before breakfast you get it on an empty stomach and for me at least, it caused me a lot of heartburn.

Good effect
Jaime 22/08/2025
The effects are felt almost immediately, in my case as usual, with some paresthesia. But it is manageable.

The miracle supplement
Luka 16/07/2025
With less than 4 grams per day, it protects the heart. At less than 2.5 grams per day, it improves athletic performance. Although still under research, it is believed that less than 2.5 grams per day may improve cognitive function.
