Natural Solutions for Depression: An Expert Review of Non-Medication Treatments

This podcast episode, hosted by psychiatrist Dr. Tracey Marks, delves into alternative and natural treatments for depression, catering to individuals who prefer non-prescription options. Dr. Marks clarifies that while these substances are often perceived as "natural," anything with a chemical effect on the body is fundamentally a drug. The episode systematically reviews eight such options: 5-HTP, Inositol, L-Methylfolate, Saffron Stigna, Sam-E, St. John's Wort, Omega-3 fatty acids, and Vitamin D, providing an expert perspective on their mechanisms, efficacy, dosages, and potential drawbacks.

The discussion highlights key distinctions and nuances for each treatment. For instance, 5-HTP acts as a serotonin precursor but has a short half-life requiring frequent dosing and can cause severe nausea. Inositol, a sugar alcohol, lacks robust studies and is typically an add-on. L-Methylfolate, the active form of vitamin B9, is crucial for neurotransmitter synthesis and is most effective as an add-on, particularly for individuals with folate deficiency who respond poorly to antidepressants. Saffron, while showing promising results in limited studies, is expensive and requires twice-daily intake, with a warning for those on blood thinners.

Further, Dr. Marks explains that Sam-E enhances serotonin and norepinephrine, effective for mild to moderate depression, but studies often have small sample sizes and it's contraindicated in bipolar disorder due to mania risk. St. John's Wort is presented as the most effective standalone herbal treatment for mild depression, but its significant interactions with other medications necessitate strict medical consultation. Omega-3 fatty acids, specifically EPA, are discussed for their anti-inflammatory properties, given depression's inflammatory component, and are recommended as an add-on therapy.

Finally, Vitamin D, primarily synthesized from sun exposure, is crucial, with many people being deficient. Supplementation is beneficial for depressed individuals who are vitamin D deficient and already on medication, serving as an add-on. A critical practical insight is that Vitamin D is fat-soluble and can accumulate, so "more is not better" without a confirmed deficiency via testing. Throughout the episode, Dr. Marks emphasizes the importance of consulting a doctor before starting any of these supplements due to potential side effects, drug interactions, and the need for proper diagnosis and dosage.

just because it's derived naturally does not mean that it's not a drug. Really anything that has a chemical effect on your body is a drug.

5-HTP is a precursor to serotonin. This means that it's part of the chemical pathway to make serotonin.

L-methylfolate is a building block for serotonin, norepinephrine, and dopamine and these are all chemicals involved in mood.

Studies have shown that people with low folate levels in the body tend to have a more severe depression and they don't respond as well to antidepressants.

When a medication is recommended for more than once a day usually it's not as effective or maybe not even effective at all if you only take it once a day.

St. John's Wort is an herb and it comes the closest to the antidepressants as far as effectiveness.

depression is thought to have a inflammatory component to it.

Vitamin D supplementation has been shown to improve depression in people on medication and who are vitamin D deficient. It was not that helpful for depressed people who were not already deficient.

Vitamin D is a fat-soluble vitamin so it can accumulate in your body so you don't want to take too much of it thinking that if a 1000 or 5000 helps then maybe 10,000 even better. More is not better unless you have a deficiency and the only way to find that out is to get tested.
