  • Made in Belgium
    Formulated and produced in Belgium with carefully selected ingredients from transparent, traceable supply chains
  • As Natural as Possible
    Our supplements are free from unnecessary additives like silicon dioxide and titanium dioxide—commonly used in conventional capsules, but not needed here.

Frequently asked questions

1 capsule per day.
We recommend you take your supplements with a meal, not on an empty stomach. 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.

Nope. Flow already contains a sufficient amount of folic acid (500 micrograms). Active folic acid is better absorbed than synthetic folic acid, which you can find in supplemenents from other brands. This means you don't need to take extra folic acid when you take Flow.

We have chosen natural and active ingredients that are well absorbed in the body. We avoid synthetic forms of vitamins and minerals, unnecessary fillers, and unnecessary colourings that are often found in other supplements. Our supplements are as natural as possible. For example, we work with Hydroxypropyl methylcellulose (HPMC) for our capsules instead of (bovine) gelatine. Hydroxypropyl cellulose is made from cellulose. In many dietary supplements, you will also find silicon dioxide, magnesium stearate and titanium dioxide. These substances are used respectively to improve capsule filling and to make the capsules white. We do not use silicon and titanium dioxide because EFSA (European Food & Safety Agency) no longer considers these substances safe due to negative effects on hereditary material (genotoxicity).

No, it doesn’t. Our supplements don't work like medications. Instead of changing something in your body, they are actually going to support normal balance and function. So they are safe to take and are not going to sabotage or negate the effect of medication.

While too much vitamin A during pregnancy — meaning over 3000 micrograms — is not good, Guud Flow only contains only 800 micrograms.
Also, the vitamin A found in Guud Flow is under the form of beta-carotene. Beta-carotene supports vision, growth, and reproduction.

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.

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.

How quickly a supplement works depends on various factors. A balanced diet and lifestyle are essential. If you have a nutrient deficiency, it will take longer to see results. We recommend taking supplements daily for 3-6 months for optimal effect. After improvement, you can take the products cyclically, for example only in the second half of your cycle when your symptoms are more severe.

Shipping is free on orders over €70. Otherwise, it’s €4,99 to EU and US; €9,99 to UK.

We make every effort to deliver your order to you as soon as possible. We try to dispatch orders placed on working days before 16:30 on the same day. However, sometimes products are out of stock and the delivery of your order may take a little longer. An indication of the delivery time is given on the product page. Should we not meet this delivery time for any reason, we will of course inform you as soon as possible.
