Find out if glucomannan and glucosamine can be taken at the same time, or if they are best taken separately.
Short answer: No known negative interactions between glucomannan and glucosamine, but they are best taken a couple of hours apart.
Glucomannan and glucosamine have no known negative interactions, but gel-forming fibers can slightly reduce the absorption of other supplements when taken at the same time, so ideally take these supplements a couple of hours apart.
Many supplements are dependent on being taken at the right time, or with the right meal, for proper absorption. For example, fat-soluble vitamins such as vitamin D should be taken together with a high-fat meal. Stimulating supplements, such as rhodiola or ginseng, should avoid being taken too late in the day.
Some supplements are known to complement each other when taken together, either because one helps the other to be absorbed, or because their effects compliment each other. Well known combos include vitamin D3, vitamin K2 and magnesium, or quercetin and bromelain, but there are many others.
Likewise, some supplements can compete for absorption or react negatively if taken together. For example, calcium and magnesium compete for absorption, so they are best taken several hours apart, and fiber-heavy supplements such as psyllium husk should be taken by themselves, separate from all other supplements.
The Vitamin Plan will automatically detect if there is a recurring theme in the supplements that you are taking, and suggest a focused addition or two for that theme. For example, if your plan seems to be mostly centered around joint health, it may suggest adding glucosamine or collagen if you didn’t add them yet.
