7 Reasons You MUST Have Optimal Vitamin D Levels

It’s time to get your vitamin D on…

Vitamin D is one of the most important biochemical markers we aim to optimise with our Manchester personal training clients. Why? Read on…

In recent years, vitamin D (actually part vitamin – part hormone) has gone from being the useless looking kid at the back of class, to centre stage; boasting a host of benefits from health to body composition and athletic performance:

1. Cut your risk of cancer: vitamin D has been shown to reduce risk of cancer in hormone related cancers, including breast, cervical, endometrial, prostate, pancreatic and colon.

2. Cut your risk of chronic conditions. Vitamin D is immune modulating, and can be of benefit in inflammatory conditions (inflammation is at the root of many chronic diseases). Studies show that risk of heart disease, hypertension, diabetes, and cognitive impairment are decreased with optimal vitamin D levels. A lack of vitamin D is also associated with depression.

3. Vitamin D is essential for muscle growth and male hormone health – even moderate levels of supplementation have been shown to increase testosterone levels by 20%.

4. Vitamin D has been shown to promote fat loss in women – low levels may pre-dispose the body to fat accumulation, and an association between obesity and low vitamin D levels has been shown in the published literature.

5. Need improved strength and athletic performance? In a number of studies those with higher levels of vitamin D showed significant improvements in strength and performance.

6. Boost your immune system. Vitamin D is essential for immune system health, priming ‘T’ cells, which can help keep you healthy.

7. Reduce your risk of osteoporosis and improve your bone health. Vitamin D is vital for calcium metabolism and bone health!

As vitamin D can be toxic to the liver at high levels (250 nmol/l +), it is essential that testing is performed on a regular basis while supplementing. Based on the latest research Optimised recommends a level of 125-180 nmol/l. The NHS currently recommends a level of 50nmol/l or above (it used to be 20 nmol/l), but don’t worry, they’ll catch up to the research in another 10 years or so.

My vitamin D level? 141.3 nmol.

Vitamin D testing is quick, accurate, easy, and relatively cheap. We supply our clients with tests which can be performed at home and are processed by our lab with results turned around in about 5 days.

To your lean, healthy, optimised future,
