Frequently Asked Questions



Guud Flow contains 500 mcg of Quatrefolic® per capsule, a highly absorbable active form of folic acid that provides the best results for your health and that of your growing baby if pregnant.

Synthetic folic acid is not biologically active – an enzyme in your body has to convert it. Unfortunately, this enzyme doesn't work properly in many people, meaning the folic acid doesn't do its job properly.

With Quatrefolic®, you don't have to worry about metabolism because you take the active form, which your body absorbs immediately. This way, you get the Guud stuff right away.

(Folic acid intake increases the woman's folate status. Low folate status is a risk factor in the development of neural tube defects in the fetus.)



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

The beneficial effect of maternal DHA intake (contributes to normal brain development and eye development of the foetus and breastfed infants) is obtained with a daily intake of 200 mg DHA in addition to the recommended daily intake of omega-3 fatty acids for adults.



Guud Flow is a multivitamin with 500 mcg of active folic acid. The recommended supplemental intake before and during pregnancy is between 400 and 500 mcg, so you don't need to take extra folic acid with Guud Flow. It's best to start taking folic acid when you're trying to conceive—if possible, three months before you conceive.

Active folic acid is better absorbed by your body. Folic acid supplementation increases the mother's folate status. Low maternal folate status is a risk factor for the development of neural tube defects in the developing fetus.

Guud Inside contains sustainable omega-3s derived from algae. Maternal DHA intake contributes to the normal brain and eye development of the fetus and breastfed infants.



For best results, we recommend taking our supplements in conjunction with a healthy lifestyle: a varied diet, habits that lower your stress levels, exercise, little or no alcohol, and plenty of happy moments.

Our supplements are formulated with combinations of scientifically researched ingredients that have been scientifically proven to address the hormone-related issues many women experience. All our ingredients are backed by official health claims, so women can support their cycle and overall health.

Several factors determine how long it takes for a supplement to take effect. A balanced diet and lifestyle are key. Your body may also have certain nutrient deficiencies. The lower your levels of these, the longer it takes before you notice something "starting to work." If there's a greater deficiency of a particular nutrient, it will take longer to replenish that nutrient supply.



Yes. We've formulated the supplements so you don't get too much of any one ingredient, meaning you can safely take all four (Flow, Glow, Inside, and Vibes) together without exceeding the recommended daily allowance of certain vitamins and minerals. Limit your zinc intake via a zinc supplement (10 mg or more) to a few weeks or months.



Our supplements are as natural as possible. For example, we use Hydroxypropyl Methylcellulose (HPMC) for our capsules instead of (bovine) gelatin. Hydroxypropylcellulose is made from cellulose, an important complex sugar found in wood and plants.

Many nutritional supplements also contain silicon dioxide, magnesium stearate, and titanium dioxide. These substances are used to improve capsule filling and to make them white. We do not use silicon and titanium dioxide because the EFSA (European Food & Safety Agency) no longer considers these substances safe due to their negative effects on genetic material (genotoxicity).

By working with rice concentrate, rice starch and transparent HPMC capsules, we offer a natural alternative.

In any case, you will find very few additives in our products!



All our supplements are gluten-, wheat-, and lactose-free and suitable for vegans. They are also free of preservatives, added sugars, and artificial colors.



All our supplements are made in Belgium and are approved by the FASFC and have a notification number.



Yes, we recommend taking your supplements with a full meal, not on an empty stomach. Swallow them with plenty of water and not with coffee.

Some vitamins and minerals are less well absorbed by the body when you take them at the same time as coffee.
