Another vital supplement for individuals on not only a ketogenic diet but any diet in general is Vitamin D3. Vitamin D is a fat-soluble nutrient. It is one of the 24 micronutrients critical for human survival. The sun is the major natural source of the nutrient and that is why Vitamin D is known as the "Sunshine Vitamin".
A Ketogenic diet may cause vitamin D deficiency. Vitamin D deficiency can result in decreased calcium concentrations and bone density. Not many foods contain vitamin D; synthesis of vitamin D (specifically cholecalciferol) in the skin is the major natural source of the vitamin.
Vitamin D3 Supports:
Bone and Muscle Health
Immune System Health
Cardiovascular and Brain Health
The recommended form of vitamin D is vitamin D3 or cholecalciferol which is the natural form of vitamin D that the body makes from sunlight. The KetoGenics™ brand contains 5,000 of Vitamin D3 (cholecalciferol)
Suggested use: 1 capsule daily preferably with a meal or as directed by a healthcare professional.
Vitamin D-3 in my mind is one of the top 3 supplements you need to take on a daily basis. The amount is up to you (be careful of diminishing returns), but along with a the KetoGenics Multi-Vitamin and Fish Oil these are a necessity. Working indoors and living in a part of the world the sun forgets about Vitamin D supplementation is essential. Since taking these I've been much less sick, seen my doctor less and feel great! Capsules of sunshine right to my door!!
