The problem is that OTC products will work differently for different people even within the same family.
If you are eating a good diet, getting plenty of exercise and still suffering from constipation then lower bower motility could just be due to age.
However, when I searched on “why does Atorvastatin cause wind and constipation”, it says:
Atorvastatin, a commonly prescribed statin for lowering cholesterol, can cause gastrointestinal side effects like wind and constipation. While it is not fully understood why this happens, it is believed to be related to the medication's impact on the gut, rather than a systematic effect on the whole body.
Impact on Colon Nerves and Motility: One of the main theories is that statins, including atorvastatin, can affect the nitric oxide levels in the body, which in turn can affect the nerves in the colon. This can make muscle contractions in the gut less effective, slowing down digestion and causing constipation.
Reduced Bowel Motility: When food remains in the colon for a longer period (slowed motility), it can lead to increased fermentation, which causes gas, bloating, and wind.
Reduced Bile Production: Atorvastatin works by inhibiting the enzyme HMG-CoA reductase, which leads to lower cholesterol production. Because cholesterol is essential for producing bile, a decrease in cholesterol can result in lower bile levels, which can also contribute to reduced bowel movements and constipation.
Depletion of Coenzyme Q10: Atorvastatin may decrease levels of coenzyme Q10 (CoQ10), a coenzyme that helps with various body processes, including digestion. This depletion may also play a role in causing constipation.
I don’t suppose there is any great harm in trying the husk but perhaps also consider a Coenzyme Q10 supplement and a nitric oxide booster. Beetroot is good for the latter.
