    Happy client

    Ik ben heel tevreden over de supplementen van Guud. Ik neem ze nu ongeveer 8 maanden en zou ze zeker aanraden. De abonnementsformule is heel gemakkelijk en ik ben daardoor nooit "out of stock". TOP!

Frequently asked questions



Guud Flow contains 500 mcg Quatrefolic®, a highly absorbable folic acid that gives you the best results for your health and the health of your growing baby if pregnant.



Ordinary folic acid and folates are not biologically active, and to be used effectively, they must first be converted into the body by an enzyme. Unfortunately, this enzyme does not work sufficiently for many people, meaning that ordinary folic acid will not be effective.



With Quatrefolic®, you don’t need to worry about converting the enzyme, as you’re taking the active form, which can be absorbed into the body immediately. Thus, giving you the good stuff straight away!



DHA contributes to the maintenance of normal brain function. The beneficial effect is obtained with a daily intake of 250 mg of DHA.



Docosahexaenoic acid (DHA) maternal intake contributes to the normal brain development and normal development of the eyes of the foetus and breastfed infants. The beneficial effect is obtained with a daily intake of 200 mg of DHA.



Guud Flow is a multivitamin and contains 500 mcg of active folic acid. The recommended extra intake is between 400 and 500 mcg, so yes, it is enough for a prenatal supplement. Active folic acid is better absorbed by your body. Supplemental folic acid intake increases maternal folate status. Low maternal folate status is a risk factor in the development of neural tube defects in the developing foetus. It is best to start taking folic acid when you are trying to conceive - if possible, three months before you become pregnant.

Guud Inside contains sustainable omega-3 based on algae. DHA maternal intake contributes to the normal brain development and normal development of the eyes of the foetus and breastfed infants.



For best results, we recommend taking our supplements in conjunction with a healthy lifestyle: a varied diet, stress-busting routines, exercise, low/no alcohol, and lots of happy times.

Our supplements are created with research-informed ingredient combinations, scientifically proven to tackle the hormone-related complaints many women face. Our ingredients are all linked to official health claims so that women can support their cycle and health.

There are several factors that determine how long it takes for a supplement to start working. A balanced diet and lifestyle is the starting point. In addition, your body may also have certain nutrient deficiencies. The less they are present in your body, the longer it takes before you notice whether something 'starts working'. If there is a greater deficiency of a particular nutrient, it will take longer for the level of that nutrient to normalize.



We have formulated the supplements to ensure you don’t consume too much of one ingredient, meaning they’re safe to take all 4 (Flow, Glow, Inside & Vibes) together without exceeding the daily recommended amount of certain vitamins and minerals. Limit the intake of extra zinc via a zinc supplement (10 mg and above) to a few weeks or months.



Ideally yes. We recommend you take your supplements with a meal, not on an empty stomach to avoid gastrointestinal problems. Swallow them with water and not with coffee. Some vitamins and minerals are less well absorbed by the body when you take them with coffee.



Our supplements are as natural as possible. We use Hydroxypropyl methylcellulose (HPMC) for our capsules instead of (bovine) gelatin. Hydroxypropyl cellulose is derived from wood cellulose.

In many dietary supplements, you will find silicon dioxide, magnesium stearate, and titanium dioxide. These substances are used to fill the capsules better and whiten the capsules. We do not use silicon and titanium dioxide because EFSA (European Food & Safety Agency) no longer considers these substances safe due to their negative influence on the genetic material (genotoxicity).

We offer a natural alternative using rice concentrate, starch, and transparent HPMC capsules.

That's why you will find very few additives in our products!



All our supplements are free from gluten, wheat and lactose and are suitable for vegans. They don’t contain added sugar, preservatives or artificial colourings.



They are made in Belgium (EU) and approved by the FAVV.
