Vision Vitamins: It’s not only WHAT you take but HOW you take it

Presently, we are witnessing new breakthroughs in helping people to keep and protect their vision. The National Institute of Health (NIH) is currently doing a study on over 4,600 people to follow the effect that nutritional supplementation can have in relation to cataracts, macular degeneration and glaucoma. This study includes the importance of not only what nutritional supplements to take, but how these nutrients should be taken.

The following is a chart that compares the absorption rates of different delivery systems:

Delivery System                                       Rate of Absorption

Pills or tablets                                                    10%

Capsules                                                            20%

Transdermal Patch                                             45%

Sublingual (droppers)                                         50%

Intramuscular                                                     90%

Intraoral Spray (under the tongue)                    95%

Intravenous                                                        100%

* Refer to most recent Physician Desk Reference NPPDR #18

One way around this problem is to take the most important nutrients orally (under the tongue) if available. Again, it’s not how much you take but how much your body tissues absorb that is important.

Intraoral and sublingual absorption has become a viable solution with the introduction of liposomes. Liposomes are little fat containers that can hold nutrients, and provide an efficient transport system that allows for maximum absorption by the body. These fat containers bypass the stomach and take a quicker route by slipping through the sub-mucosal membrane under the tongue and directly into the bloodstream. With a greater concentration of nutrients in the blood, more nutrients reach their intended destination, thereby requiring a lower dosage intake.

The intraoral spray or sublingual method of delivery is also very helpful for individuals who have difficulty swallowing pills or capsules, and is also cost effective since a lower dosage of nutrients is needed.

Remember, more nutrients in a pill or capsule is not necessarily better. What is important is how accurately can we best insure the intake of “therapeutic dosages,” recommended in many Other variables affect the absorption rates as well including: 1) the quality of the nutrients, 2) whether they are buffered and time-released, and 3) how the nutrients are combined with other nutrients.

Often times we know how much nutrients we want patients to take therapeutically for patients conditions, but what we do not know is how much of the nutrients prescribed are absorbed into the patients bloodstream through their digestive tracts. We do know that as one gets older, one’s absorption rate through the intestinal tract reduces, sometimes significantly, particularly when combined with serious health conditions, or particular digestive disorders such as ulcers, diverticulitis, gastric problems, acid reflux, etc.

Other factors that affect absorption include the following:

1) Stress restricts the flow of blood in the body by tightening muscles, and restricting the free flow of fluids. Meditation, yoga, tai chi or even daily walks in nature can all help reduce stress significantly.

2) Eating slowly. We should be eating our food slowly and thoughtfully. Try never to eat on the run, and don’t eat while conversing, writing, doing work, etc. Make eating a special time for yourself.

3) Exercise helps the body rid itself of harmful toxins that build-up daily. Numerous studies have shown that even a brisk walk of 20 minutes per day can have a major impact in reducing development of disease such as heart disease, and has even been shown to reduce high eye pressures in cases of glaucoma.

4) Positive thinking. In Chinese medicine, excessive thoughts of anger, worry, resentment, grief and fear all have significant effects on the free flow of “energy” in our body.

5) Eating healthy food. Our bodies crave fresh food, particularly fruits, vegetables and grains. These foods provide energy to our bodies in the form of vitamins, minerals, and natural enzymes. Excessive intake of “dead” food such as fast foods, or highly processed foods, requires our bodies to use its own enzymes and energy to digest food in an attempt to separate whatever limited nutrients may be available.

Tips for Taking Vitamins and Maintaining Good Digestion

1) If possible take vitamins with food. Digestive enzymes are stimulated when eating and aid in nutrient absorption.

2) Limit fluids during meals to improve digestion. Especially avoid cold or iced drinks when eating.

3) If possible, use liquid and/or sublingual vitamins. They are the most easily assimilated by the body. Capsules are the next best choice.

4) If vitamin capsules cannot be swallowed, open up the capsule and mix the contents with juice or yogurt.

5) A small amount of apple cider vinegar, taken just prior to a meal, will stimulate production of digestive juices.

6) If taking antibiotics, take acidophilus supplements between dosages. This will help build up the good bacteria in the digestive tract destroyed by the antibiotics. It is especially important for elderly patients to take acidophilus on a regular basis.

7) Vitamin A and Lutein compete for absorption, so take separately.

Useful information. Yes, it's not only what but how we take our meds and vitamins. But food is better than meds and vitamins and supplements. Egg yolk contains Xeaxanthin that, so far I know, prevents macular degeneration. We can also take carotenoid vegetables (leafy green vegetables, colourful vegatables, red peppers and carrot) that contains beta carotene, vitamin A, lutein and xeaxanthin. Most of the vegetables we can teat raw. These can be beneficial for our eye health as well as fighting cancer. These are excellent anti-oxidants too. Thank you Dr. Grossman, for your article.

If necessary to prevent the oral route one may use/try the transdermal one by mixing the wanted compound like resveratrol with some DMSO (dimethyl sulfoxide), a fluid containing 30% water. and smearing the mixture on your thy or belly using your hands. By DMSO the resveratrol is taken up immedately.
The only drawback is the smell of garlic afterwards. DMSO itself is very good for your health.

So, Bert, would not the resveratrol have to be in liquid form? Or may it be in powdered form, like crushing the pills first, then mixing? Would wonder if that would be absorbed in powdered form even with DMSO.

It is interesting how DMSO has the ability to penetrate the skin deeply and act as a carrier taking along with it some other substances. As I'm losing hair, I hope someday someone will offer a scalp nutrition compound with DMSO as a carrier to really get down to the hair roots and nourish them.
