Vitamin C

Vitamin C is known to be a powerful antioxidant (1). Studies have suggested that it can increase endothelial nitric oxide by protecting it from oxidation and increase synthesis, another function that Vitamin C has suggested includes reducing blood pressure (2), however the only proven function of vitamin C is the prevention of scurvy (3).

L-ascorbic Acid

Ascorbic Acid Is another form of VItamin C.

Microcrystalline Cellulose

Micro Crystalline Cellulose is a non-active ingredient which is made up of refined wood pulp. This substance does not degrade during digestion and is preferable in tablets due to it being able to form hard but dissolve quickly.

Vegetable Stearic Acid

Vegetable stearic acid is also known as magnesium stearate. Magnesium stearate does not induce any nutritional benefits. The main reason for this substance being in the supplement is that it is a lubricant for the machinery that manufactures the product.

Vegetable Cellulose

Cellulose is used as a viscosity modifier or thickener, and to stabilize emulsions in various supplements and other products. It is known for its excellent water retaining capacity.


Silica is also known as Silicon Dioxide. Silicon dioxide doesn’t add any nutritional benefits to this supplement. The main reason for silicon dioxide in this supplement is that it aids in the even distribution of the active ingredients in this supplement.

Vegetable Glycerin

Glycerin is a thick colourless, odourless liquid which has been suggested to be a hyper hydrating agent (4). The main reason for this is that it can increase blood osmolality which augments the retention of water (5). It has been suggested to lower heart rate and prolong exercise (6), however research is still sparse on this ingredient further studies are needed in order to fully understand the capabilities of glycerin.


This product does contain ingredients that can help support the immune system and boost collagen formation. It can also reduce blood pressure. This product can be consumed throughout the day.
