Some of the best selling products that I have formulated:

Mind Power Rx for optimal brain function, alertness, focus, and clarity of thinking. The mental effects are often noticed the same day after taking one capsule. There are ways to improve memory with several dietary supplements. Free samples are available at Physician Formulas website. Try some.


Eyesight Rx works within hours to improve your day and night vision. Colors become brighter and clearer. Just looking at objects and nature becomes more pleasurable. This is a highly advanced, concentrated blend of several herbs and nutrients that help improve visual acuity so you can see distant objects clearer and read small print easier.


Passion Rx for sexual enhancement and enhanced libido, stamina, and sensation - works in men and women within 2 to 3 days. It incorporates potent sexual herbs from all over the world in one formula to improve sex drive, pleasure, performance, and stamina in a man and woman. Do you know what kind of medical conditions cause erectile dysfunction and how to use food, spices, herbs and natural therapies that have an influence on impotence treatment? Is there a way to reduce the need for Viagra and other prescription medications or hormones?

Diet Rx is a formula with more than 20 ingredients that works the first day to reduce your appetite so you eat less. Most users report that they lose the urge to overeat and have less interest in eating desserts. Diet Rx also provides a pleasant energy increase so you want to be more active and use up more calories. Free sample bottle of 15 capsules is available. Try them for a few days.

Joint Power Rx for joint health with glucosamine, chondroitin, msm, cmo, cat's claw, devil's claw, turmeric, and boswellia. As we age our joints begin to degenerate and certain natural supplements that are included in Joint Power Rx could help slow this process.
Osteoarthritis is a common condition that occurs with aging. What can be done to help reduce joint pain symptoms?

Prostate Power Rx with saw palmetto, pygeum and several herbs involved in prostate health. Prostate Power Rx also has beta sitosterol and lycopene. In terms of prostate health and enlargement, what are the latest findings on the role of food, diet, and lifestyle factors that influence the gland? Do you really need a PSA test?

MultiVit Rx is a high quality daily vitamin, mineral and nutrient product that provides a sense of enhanced energy and improved wellbeing the very first day of use.

We suggest you consult with your health care provider to find out what supplements are right for you. Even natural remedies can at times have serious side effects especially in combination with prescription medications or in those with unstable medical conditions.

What Visitors Are Saying:

Thank you the work you do and share with everyone. It's a fantastic resource.

I am an absolute fan of your work and literature - it is a treasure trove of information.

Let me say how impressed I am that there's someone like you doing such a deep analysis of supplements.

I love (and I mean love!) your site! In fact, I spent my afternoon yesterday combing through your posts. I am a huge fan.

Thank you so much for your site. It is the most intelligent one so far and the only one I trust and respect.

As an individual with respect for allopathic medicine and a passion for holistic medicine, I've come to enjoy Dr. Sahelian's online writings. I appreciate the comprehensive, accurate and up to date information he provides.

Dr. Sahelian, thanks so much for your forthright, empirically oriented, common sense approach to the information you provide. Your reviews and assessments of supplements are most informative and useful. I always read them before trying anything new. For example, I found your insights on the potential insomnia effects of Coq10 and tyrosine to perfectly align with my own experience; yet no one else seems to write about this, even recommending 300 mg or more of Coq10 per day. If I took this I wouldn’t sleep for days.

Thank you for such an informative, and most importantly, honest resource on supplements. You provide research with every review and list side effects many others don't care to.

Thank you for changing my life and many of my loved ones. You are my favorite Dr. to seek answers online about supplements. My doctor now knows that whatever prescription she suggests, I will be researching supplements that have the same action in the body, and I seek your advice first. I tell others that your advice has done me more good than 30 years of doctors who are not willing to look anything up that is not in the 12 (or so) most common causes of fatigue.

I am very grateful to you for the wealth of nutritional information you provide to the public. I also appreciate your honest analysis on dietary supplement topics you discuss.

Your website is the official site for our family and for all of our research and orders and it is because of your honesty and integrity.

Thank you for your many years of research and product development, and for your cautious, conservative and informed approach to supplementation. You have my admiration and respect.

I always rely on Ray Sahelian, M.D. for accurate and honest opinions. He is a professional in every way and that is why he is valued in our family and others who seek what he has to share.

Q. Why do you recommend taking a "vitamin supplement holiday"? After all, we continue to take in vitamins daily from our food without apparent harm?
    A. We ingest quite a variety of vitamins and minerals through our diet, often in small, well balanced proportions. Many multivitamin supplements have high amounts of certain vitamins and minerals and not necessarily in the same balance the body is used to through foods. Hence, to be cautious, I find a reasonable approach is to take breaks. Other doctors or scientists certainly have different opinions.

Calcium how much do you need? High dosages, such as 800 to 1,500 mg were recommended by doctors for many decades to women with osteoporosis, but it is possible that high amounts could lead to damage to blood vessels or increase the risk for heart attack. Limit daily intake from supplements to no more than 400 to 600 mg a day.

Email received - As a student graduating with a degree in human nutritional sciences and entering the field of naturopathic medicine, I am only further motivated to pursue my education because of individuals such as yourself. It is always wonderful to see medical doctors who have an amazing understanding of natural, alternative, complementary medicine and who have dedicated their life to helping others and provide them with valid information on natural health care/supplements. It is nice to read information from a website that has such honest thoughts, opinions as well as actual facts.

Would it be of benefit to open capsules and crush all tablets to maximize absorption of supplements or is this overkill?
   As a general rule this is not necessary but each capsule or tablet from different manufacturers is different and each person has a different absorption ability. Some people take several supplements or combinations that are excessive, or high dosages may interact negatively with certain prescription medications they are taking, so even if a little less is absorbed by not opening certain capsules or crushing certain tablets, perhaps the resulting potential lesser absorption is desirable. Overall though, for practical purposes, it is not necessary to open capsules or crush tablets unless the supplement is required in high dosages to treat a particular medical condition and the patient has difficulty with stomach acid production or has a history of intestinal malabsorption.
