Vitamin D is linked to muscle growth, immunity and a feeling of happiness

Most of us are deficient

77% of Americans are deficient in Vitamin D. Most of us have been taught that just getting time in the sun is enough. But it's still not enough. Between the months of November and February anyone living north of the 35th parallel will be deprived of Vitamin D if they depend on the sun.

So, is there a solution that doesn't include moving south?
Optivida Health Vitamin D is a unique plant-based Vitamin D supplement with no synthetic ingredients, chemicals or food isolates.

Quickly and Completely Absorbed

Optivida Vitamin D is made from our specially-grown white button mushrooms. Your body will naturally digest and use mushroom much more than other vitamin D products made from questionable compounds.
To increase the amount that is absorbed we combine the Vitamin D with magnesium. It is known to boost the absorption of Vitamin D into the body. Magnesium acts as a hostess that guides the Vitamin D into the bloodstream where it can effectively go to work.

Enzymes and Food Energy

Optivida Vitamin D contains many digestive enzymes help with the digestion of food. These enzymes help break down the food you eat to release the energy. Without all of the proper enzymes your digestion is incomplete.

Strength and Muscle Growth

Studies show a link between Vitamin D deficiency and muscle weakness. It is also linked to muscle growth and recovery. Vitamin D receptors are found in almost all tissues of the body. Vitamin D works in some of those tissues as a regulator of muscle growth.
Vitamin D supplements may improve muscle strength by increasing the size and amount of type II (fast twitch) muscle fibers. Studies show that Vitamin D may serve a vital role in muscle growth, athletic performance and injury prevention.
