Is there any kind of supplement that I can slip in my husband's protein shakes to help increase his libido?

We do not advocate one treatment over another or recommend that you take health matters in your own hands by self-diagnosing any condition or treating yourself without the benefit of checking with a doctor first.
With that said, there are plenty of documented studies and plenty of scientific research pointing to the benefits of natural medicine and plant based or plant derived products that can help to alleviate or eliminate symptoms of certain conditions.
There are clinical studies that have been done throughout the world on such things as Vitamin C, Aloe Vera and dozens of other botanical products. The medicinal properties of raw Garlic have been known for centuries as well as the anti-bacterial properties of honey, which has been used in biblical times for a wound healing agent.
Western medicine has helped save lives and many traditional treatments are vital and necessary to a person's health. However, there may be limitations to conventional treatments for cancer like chemotherapy and radiation. While I do not say that there is a cure for certain types of cancers, there are those people who have used alternative treatments like hyperbaric oxygen chambers and ozone therapy to help rid themselves of cancer. Why some studies have shown that hyperbaric oxygen therapy has helped stroke victims and those suffering from multiple sclerosis and cerebral palsy.
Here are some sad facts of Alternative Medicine in the US:
The FDA promotes only pharmaceutical drugs and has a decades-long record of not approving, or even looking at, anything alternative. Again, this is the way of the world and you must face it.

In medical lawsuits, well-meaning but misinformed juries rule against doctors unless they've used conventional drugs, surgery and radiation.

Doctor's malpractice insurance won't cover them if they use "unapproved" alternatives.

Their state medical boards may fine them heavily, suspend their license to practice or even revoke it.

The FDA may do the same and confiscate patient records and medical equipment.

Doctors may lose their right to see their patients in hospitals.

Yet, to this day, thousands upon thousands of people stricken with all kinds of serious medical conditions have felt the inadequacy of traditional or conventional medicine and have sought out alternative treatments, whether they be approved by the AMA or FDA.
Whether it is Naturopathy, Homeopathy, Traditional Chinese Medicine, Ayurvedic or Holistic Medicine, there are other therapies and natural approaches to diseases and many of them work better than the recommended protocols and without many of the harmful side effects.
