This is a product that past podcast guest and ketosis expert Dr. Dominic “Dom” D’Agostino (@DominicDAgosti2) loves, has tested, and recommends to others. It was developed by Csilla Ari D’Agostino. I’m personally testing the version without caffeine for help with altitude acclimation and exercise with hypoxia.

This product was recommended to me by Amelia Boone, known as the Michael Jordan of obstacle course racing. I've consumed gelatin for connective tissue repair in the past, but never stuck with it because of its texture. Amelia saved my palate and joints by recommending this type, which blends easily.

I travel with insulin-mimetic compounds such as Alpha Lipoic Acid. These supplements allow you to minimize your own insulin response. Before I describe these, WARNING: I am not a doctor and don’t play one on the Internet. If you have any medical condition (especially Type I Diabetes), you need medical supervision to use such supplements. Now, back to my personal use -- Let’s say you’re at a conference, and to be social, you end up eating meals that are high in carbohydrates (e.g. pasta, desserts, etc.). These types of supplements can help mitigate the damage.

In a Facebook video, Ferriss described his top four supplements to take for recovery after a brutal workout, and L-Glutamine was the first one he mentioned. Ferriss also mentions taking L-Glutamine in the 4-Hour Body as part of Occam’s Protocol, in which he gained 15 pounds of muscle. Ferriss tends to take L-Glutamine in high doses. He recommends consuming 80 grams per day for the first five days, taking around 10 grams every two hours. After the loading period, he says to take 10-30 grams per day post-workout. Ferriss doesn’t say what brand he uses, but Pure Encapsulations is a brand highly recommended by the likes of Dr. Rhonda Patrick and Joe Rogan.

Apple cider vinegar is the health miracle everyone is talking about, and for good reason. Taking a teaspoon of apple cider vinegar in the morning and at night as Tim Ferriss does, can help improve immune function among others. Apple cider vinegar benefits include improving weight loss, dropping blood pressure and cholesterol levels, stabilizing blood sugar, enhancing skin health and relieving acid reflux symptoms. Tim uses and will only recommend Bragg Unfiltered Apple Cider Vinegar. If you can’t stomach the taste, it is also available in pill-form.

Ferriss takes 5mg of NCI Advanced Research Lithium Orate daily to stage off depression. Lithium orotate is a substance that consists of lithium (an alkali metal) and orotic acid (a compound produced naturally in the body). Available in dietary supplement form, lithium orotate is touted as a natural treatment for a wide range of mental-health problems. Lithium has been known for its curative powers for centuries, if not millenniums. Lithia Springs, Ga., for example, with its natural lithium-enriched water, appears to have been an ancient Native American sacred site. By the late 19th century Lithia Springs was a famous health destination visited by Mark Twain and Presidents Grover Cleveland, William Howard Taft, William McKinley and Theodore Roosevelt. In alternative medicine, lithium orotate is purported to treat and prevent the following conditions: alcoholism Alzheimer’s disease anxiety ADHD bipolar disorder cluster headaches depression glaucoma insomnia migraine Parkinson’s disease PTSD In addition, lithium orotate is used to reduce stress, relieve pain, and improve memory.
