Vitamin D is naturally produced in our skin cells when they are exposed to sunlight, or – more specifically – to ultraviolet B rays in sunlight. Without it, our endocrine (hormone) system can’t do its job effectively. Try to get outside at least 10-20 mins a day, and exercise outdoors when you can. Or choose a natural, vegan supplement like Lifestreams Vitamin D3 spray. You’ll find Lifestream products in your health food store or pharmacy across Oz and NZ, or on line at www.planethealth.com.au.
