Western diets, which typically contain large amounts of energy-dense processed foods, together with a sedentary lifestyle are associated with increased cardiovasclar risk. Vegetarians can stay very healthy if they pay extra attention to certain nutrient requirements, including adequate protein intake. They are likely to ingest a good amount of beneficial plant substances such as carotenoids. Vitamins and nutrients that are found in very small amounts in a vegetarian diet and are likely to be beneficial for nutritional enhancement of a vegetarian include:

B12 vitamin, also known as methylcobalamin -- B12 is crucial for healthy red blood cells and the neural system.
Carnitine is a nutrient that helps with energy production in mitochondria and helps form acetylcarnitine.
CoQ10 is another nutrient crucial for energy metabolism within mitochondria.
Creatine is a nutrient that helps form stronger muscles and adds strength. Vegetarian body building enthusiasts could benefit from creatine along with protein supplements. Creatine monhydrate is a helpful supplement for muscle mass growth and certain sports.
Fish-Oils provide important omega3 fatty acids such as DHA and EPA. Alternatively, Flaxseed oil could be a partial substitute. Flax seed oil provides omega3 fatty acids that may be converted into EPA and DHA, but there is no guarantee that such conversion will occur in adequate amounts. If you wish to take DHA in fish oils from a vegetarian source, consider DHA from algae.
Iron deficiency can cause fatigue. Iron deficiency, even to a moderate degree, can hinder memory and learning -- but iron supplements can turn those problems around.

Vegetarian nutrition study, influence of diet on collagen synthesis
Practically speaking, one wonders if a vegetarian diet leads to more wrinkles?

Vegetarian diet affects genes of oxidative metabolism and collagen synthesis.
Ann Nutr Metab. 2008; Karlic H, Schuster D, Varga F, Klindert G, Lapin A, Haslberger A, Handschur M. Ludwig Boltzmann Institute for Leukemia Research and Hematology, Hanusch Hospital, Vienna, Austria.
A vegetarian diet is known to prevent a series of diseases but may influence the balance of carbohydrate and fat metabolism as well as collagen synthesis. This study compares expression patterns of relevant genes in oral mucosa of omnivores and vegetarians. Quantitative reverse transcriptase polymerase chain reaction was applied for analysis of mRNA levels from carnitine transporter OCTN2, hepatic CPT1A and nonhepatic CPT1B isoforms of carnitine palmitoyltransferase and collagen (CCOL2A1) in oral mucosa. Compared with volunteers with traditional eating habits, carbohydrate consumption was significantly higher (+22%) in vegetarians. This was associated with a significant stimulation of CPT1A (+50%) and OCTN2 (+10%) and a lowered collagen synthesis (-10%). These novel findings provide further insight into the association of a changed fat metabolism and reduced collagen synthesis in vegetarians, which could also play a role in the aging process.

Vegetarian protein sources
Legumes have good protein, including Garbanzo beans, Kidney beans, Lentils, Lima beans, Navy beans, Soybeans, and Split peas.
Nuts and seeds are a good protein source for vegetarians, including Almonds, Cashews, Filberts, Hemp Seeds, Peanuts, Pumpkin seeds, Sesame seeds, Sunflower seeds, and Walnuts.

Plant proteins have a reduced content of essential amino acids in comparison to animal proteins. A reduction of limiting amino acids (methionine, lysine, Tryptophan) means lower protein synthesis in the body and nutrition deficiencies may occur. Those who consume vegetarian nutrition diet have a higher incidence of low protein in the blood due to significant reduction of methionine and lysine intakes. On the other hand, lower intake of these amino acids provides a preventive effect against cardiovascular disease. Vegetarians have a significantly higher intake of non-essential amino acids arginine and pyruvigenic amino acids glycine, alanine, serine. When plant protein is high in non-essential amino acids, down-regulation of insulin and up-regulation of glucagon is a logical consequence. A sufficient consumption of plant proteins has the protective effects against chronic degenerative diseases.

Kidney disease and protein intake
Are high-protein, vegetable-based diets safe for kidney function? A review of the literature.
J Am Diet Assoc. 2007 Apr; Bernstein AM, Treyzon L, Li Z. Department of Nutrition, Harvard School of Public Health, 665 Huntington Ave, Boston, MA 02115, USA.
In individuals with chronic kidney disease, high-protein diets have been shown to accelerate renal deterioration, whereas low-protein diets increase the risk of protein malnutrition. Vegetarian diets have been promoted as a way to halt progression of kidney disease while maintaining adequate nutrition. We review the literature to date comparing the effects of animal and vegetable protein on kidney function in health and disease. Diets with conventional amounts of protein, as well as high-protein diets, are reviewed. The literature shows that in short-term clinical trials, animal protein causes dynamic effects on renal function, whereas egg white, dairy, and soy do not. These differences are seen both in diets with conventional amounts of protein and those with high amounts of protein. The long-term effects of animal protein on normal kidney function are not known. It appears that high intake of animal and vegetable proteins accelerates the underlying disease process not only in physiologic studies but also in short-term interventional trials. The long-term effects of high protein intake on chronic kidney disease are still poorly understood. Several mechanisms have been suggested to explain the different effects of animal and vegetable proteins on normal kidney function, including differences in postprandial circulating hormones, sites of protein metabolism, and interaction with accompanying micronutrients.

Vegetarian Recipe
For a few vegetarian recipes, see diet page that provides a great deal of practical advice.

Vegetarian food recipe - Vegetarian Cuisine
Countless vegetarian cookbooks are available that have healthy recipes for all vegetarian meals, including vegetarian breakfast, lunch and vegetarian dinner. You can also find new recipes in any of a number of vegetarian magazine options - such as Vegetarian Times - on the newsstands. You may also consider joining a vegan or vegetarian society or group that meat regularly to share meals, a dish, and recipes. You may also visit a vegetarian restaurant.

Vegetarian Research questions
Q. Does a vegetarian have more side effects from taking a yohimbe bark capsule than a non vegetarian?
   A. We don't think a vegetarian nutrition intake will influence the reaction to herbs used for sexual enhancement.

I've been a life-long vegetarian and have always taken multivitamin supplements with iron. I am now 51 and menopausal. My doctor tells me I should take more calcium and vitamin D. I would like to try Veg-Rx as I have had good success with some of your other products. I am wondering if it would be an appropriate supplement for me and whether it contains enough calcium and vitamin D, or if I would need to take additional supplements with it.
    There is 400 units vit D and 400 mg of calcium citrate in 4 capsules. This is usually sufficient for most people but if your diet does not have a good content of calcium or vit D, then your doctor may recommend taking more.

Hi, I'm currenty taking three products: Veg Rx, Prostate Power Rx, and Joint Power Rx. I'd like to know if, with the exception of the gelatin capsule in the latter two, these supplements are entirely vegan. For example, the Veg Rx label states that it contains no milk derivatives, but does not mention eggs, which makes me believe some of its components may be extracted from eggs.
    There are no eggs or egg derivatives in Veg Rx.
