As a Registered Dietitian, I tell my clients that in most cases it’s okay to mix their daily supplements in order to make it easier to take them consistently. But, you might be wondering if this is the case with collagen and Metamucil.
You can mix collagen powder with Metamucil because they don’t interfere with each other. It is an especially good combination for those trying to lose weight since it increases fullness levels and prevents snacking throughout the day.
Also, it can help improve gut health and fight constipation.
While you can mix collagen powder with Metamucil, timing your intake and mixing them properly is important so you can maximize the benefits of each supplement. I’ll explain the how-to below.
- I put together a complete guide on everything you can mix collagen powder with – check it out if you want my list of top liquids and foods.
Benefits of Mixing Collagen Powder With Metamucil

1. Consistency in Taking Supplements
One of the greatest advantages of stacking supplements (i.e., combining multiple supplements together) is that it can help you remember to take them, increasing consistency.
Collagen and Metamucil work when you take them regularly. If you constantly forget to take them, you might not get the desired results. But the more frequently you use them, the more benefits you can obtain.
In my experience, taking supplements at different times increases the risk of forgetting to take one. But combining them makes it more likely that you will take all of them.
Hence, it’s better to take them at the same time. It can be at breakfast, lunch, dinner, or with a snack. The time of day doesn’t matter as long as you take them regularly.
2. Better Bowel Movements
Metamucil can improve gut health – since it’s fiber, it can help regulate your bowel movements and fight constipation.
Collagen can also have positive effects on gut health. It might help improve the intestinal lining, reducing the risk of a leaky gut (a condition that can make your intestinal wall more permeable, allowing bacteria and toxins to enter the body).
However, more research still needs to be conducted to determine the exact impact collagen has on gut health.
3. Reduces Appetite
Metamucil (fiber) and collagen (protein) are both hard to digest. They remain longer in the stomach, thereby increasing the feeling of fullness.
For those on a weight loss journey, this is a huge advantage. Feeling fuller for longer makes you less likely to snack throughout the day. Also, you may be able to reduce the portion sizes of your main meals (breakfast, lunch, and dinner) because you won’t be as hungry.
All these changes can lead to a caloric deficit (eating fewer calories than you burn every day) and weight loss.

4. Better Flavor
Finally, collagen isn’t the tastiest supplement. But Metamucil often comes flavored, so combining collagen and Metamucil can make collagen more appealing and easier to take.
This can lead to being more consistent with taking collagen.
Drawbacks of Mixing Collagen Powder With Metamucil
1. If You Aren’t Used To High Fiber, Then It Might Create Stomach Discomfort
The only drawback of mixing collagen powder with Metamucil is that it can create stomach discomfort – but only with individuals who aren’t used to consuming a diet high in fiber. This is mainly due to Metamucil.
People not used to fiber might get stomach problems like bloating, gas, and stomach cramps.
To avoid any stomach discomfort, make sure to add Metamucil slowly. Start with half a teaspoon and increase it every few days until you reach the full desired dosage.
How To Properly Add Collagen Powder To Metamucil

Follow these steps to mix collagen powder with Metamucil for a great-tasting, filling drink.
Step 1
Grab a glass or a bottle and pour 2-3 oz of the liquid of your choice (water, milk, orange juice, or Gatorade). To make it dissolve better, ensure the liquid is at room temperature or slightly warm.
If the liquid is cold, it is more likely that the drink will clump.
Step 2
Add your desired amount of collagen and Metamucil to the liquid. Typically, the serving sizes are 1-2 scoops of collagen, depending on the brand, and 2 teaspoons of Metamucil.
If you use a shaker, blender, or milk frother, add both ingredients at the same time.
You can use a fork if you don’t have any of the tools mentioned above. However, this can lead to clumping. To prevent this, add either collagen or Metamucil on its own. Mix it thoroughly, then add the other supplement.
Step 3
Once everything is completely blended, add the remaining liquid. If you want the drink to be colder, now is the time to add ice.
What Liquid Should You Use To Mix Collagen Powder & Metamucil?
Water or other water-based liquids are the best options for mixing collagen and Metamucil. They can provide a uniform consistency and prevent you from having a clumpy drink.
Some of the liquids I recommend are:
- Water
- Milk
- Plant-based milk
- Kombucha
- Tea
- Coffee
- Coconut water
- Fruit juice (without pulp)
The thicker the liquid, the harder it will be to dissolve, so avoid using options like aloe vera.
Will the Metamucil Dissolve With Collagen Powder? (And Does It Matter)
Yes, Metamucil will dissolve with collagen powder. However, it also depends on following the steps mentioned above and choosing the right temperature and liquid consistency.
With that said, even if the Metamucil and collagen don’t dissolve, it won’t affect the efficacy.
Remember that cold liquids are a poor medium to dissolve most supplements. For that reason, make sure to choose room temperature or slightly warm liquids. This will help you have a drink without any clumping.
However, if it clumps, you can still obtain all the benefits from Metamucil and collagen powder. It just
