Tablets, capsules or liquid supplement?

All offer scientifically proven safety and effectiveness.

The liquid is better assimilated. Therefore, its absorption is greater. That is, they are more effective. There is 100% certainty of absorbing supplements in liquid form; while the capsules have only 10 to 25% absorption, so imagine what you are missing.

Most of the time, liquid supplements are created from totally natural plant sources. Therefore, they taste better than pills because they have fewer synthetic ingredients.

The supplements have the advantage of having all kinds of additional ingredients that cannot be obtained with tablets, such as fruits, vegetables and other nutritional contents. Therefore, in a liquid supplement, we have everything to avoid nutritional deficiencies. It is not necessary to have so many bottles of pills, only one is enough.

In addition to being assimilated more easily, its absorption is also faster. Therefore, supplements are integrated almost immediately into the blood flow.

Liquid supplements are perfect for babies, toddlers and older people.

The concentration of vitamins in the liquid can be 3 to 5 times higher, which increases its effects.

The ingredients are not compressed, because they have no synthetic compounds. If the ingredients are compressed, their digestion becomes more difficult. The liquids are especially good for older people due to their inability to assimilate food digestive systems.
