Vindicate (VitamIN D treatIng patients with Chronic heArT failurE) is the name of a just completed study of Vitamin D supplementation in patients with Heart failure. The findings are amazing!
Simply taking 4000UI (0.1 mg) of a Vitamin D3 supplement daily could actually cure heart failure.
The double blind clinical study was conducted on 163 heart failure patients, over a period of a year. The average patient age was over 70 and researchers measured the actual amounts of blood each heart pumped. Patients were divided into two groups, one group receiving a placebo and the other received the Vitamin D3 supplement. Patients taking the Vitamin D supplement saw an increase of between 26 and 34 percent in the amount of blood pumped by the heart chambers. This does not mean that the participants achieved better exercise capability, just that their hearts were able to pump much more blood than the control group. The patients did see an improvement in symptoms of breathlessness, tiredness and swolen ankles.
The average Vitamin D3 supplement that you can purchase at your pharmacy contains anywhere between 100UI and 1000UI per capsule or tablet. The minimum daily recommended dosage of Vitamin D is 600UI for people between 1 and 70 years of age.
Vitamin D rich foods that you could include in your diet are:
- Eggs (yellow/yolks) Vitamin D: per each on average 0.01mg
- Oily Fish (tuna, mackerel, and salmon) Vitamin D: between 0.05mg per 200cal serving and 0.01mg per 200 cal serving
- Beef liver Vitamin D on average 0.025mg per 200cal serving
- Cheddar Cheese Vitamin D: 0.015mg per 200cal serving on average
- Milk Vitamin D: 0.005mg per 200cal serving on average
Foods with added Vitamin D usually contains very small amounts (on average 200i.u /portion (about .0005mg – the study supplemented with 100mg)
You can calculate the mg amounts of Vitamin D in your supplements from the UI number. 1000UI is equal to 0.025mg
