Ashwagandha comes from an evergreen shrub used in Ayurvedic medicine. It is used to help the body manage stress, anxiety, brain fog, and fatigue by acting as an adaptogen to balance the stress hormone cortisol.

| Key Benefits | Who May Benefit | Who Should Use Caution |
|---|---|---|
| – Stress and anxiety relief – Muscle gains, increase T – Subclinical hypothyroidism – Cognitive function, focus, mood – Improved sleep quality – Sexual function (women) |
– Individuals with HPA axis/cortisol dysfunction – High anxiety/stress with certain genotypes – Men seeking to boost testosterone levels |
– People with BChE mutations (possible nightshade-family issues) |
Ashwagandha may be beneficial for these highlighted variants:
Article: Cortisol and HPA axis dysfunction:
Research shows ashwagandha effectively regulates cortisol levels in people with HPA axis dysfunction. Genetic variants can increase susceptibility to issues with the HPA (hypothalamus – pituitary – adrenal) axis, including altered cortisol rhythm. (Please read the full article for details):

Full article and details on berberine
Berberine is a natural supplement with some amazing research for reducing high blood glucose levels and high cholesterol. The drawback, though, is poor absorption in the intestines, decreasing its effectiveness.
| Key Benefits | Who May Benefit | Who Should Use Caution |
|---|---|---|
| – Lowers blood glucose – Improves LDL cholesterol and triglyceride levels – Helpful for NAFLD (fatty liver disease) – Improves intestinal barrier function – Beneficial for PCOS |
– Individuals with high LDL due to PCSK9 variants – People with high Lp(a) |
– People on prescription medications that utilize CYP3A4 and CYP2D6 (especially if combined with SNPs) -People with G6PD deficiency |
Berberine may work well for:
Article: PCSK9 variant with high LDL cholesterol:
Berberine is a natural inhibitor of PCSK9 and has been shown in human studies[ref][ref] and cell studies[ref] to decrease cholesterol.For someone with variants that increase PCSK9 and increase cholesterol (below), berberine may be beneficial for lowering cholesterol. Talk to your doctor, of course, if you have questions.

Cautions with berberine:
- Berberine uses CYP3A4 and CYP2D6 enzymes for metabolism. Thus, it may interact with medications that also use those enzymes. If you are on prescription medications, talk with your doctor before adding in a bunch of berberine.
- Check your CYP2D6 genetic variants and check your CYP3A4 variants here.
- The interaction with berberine may be important if you have slower CYP2D6 or CYP3A4 function – along with taking a medication that utilizes these enzymes.
Researchers also caution that people with G6PD deficiency may have side effects from berberine.

Detailed article on quercetin here.
Quercetin is a natural flavonoid that acts as both an antioxidant and an anti-inflammatory. It is found in low levels in many fruits and vegetables, including elderberries, apples, and onions.
| Key Benefits | Who May Benefit | Who Should Use Caution |
|---|---|---|
| – Decreases oxidative stress – Reduces blood pressure – Inhibits mast cell activation – Decreases uric acid – Fights upper respiratory infections |
– Individuals with histamine intolerance SNPs – Someone who wants to prevent gout – Individuals looking for natural ways to lower blood pressure |

Precautions with Quercetin:
COMT interaction:
Quercetin has a catechol structure and is partly metabolized through the COMT enzyme. If you carry the slower version of COMT, you may want to be careful and not go overboard with quercetin. This may be more important if taking more than one supplement that utilizes COMT (or at high doses).

| COMT | rs4680 | — | Val/Val – fast (higher) COMT activityVal/Met – intermediate COMT activity (most common genotype in Caucasians)Met/Met – slow (40% lower COMT activity) | A | 0.48 |

Cautions with hesperidin:
Hesperetin is an inhibitor of CYP2C9. If you have variants below, read more here, and then use caution when combining with medications that are metabolized through that pathway.

- Alpha-1 Antitrypsin Deficiency: Hesperidin inhibits inflammation by blocking the release of TNF-alpha.[ref]
- Advanced Glycation End Products: Hesperidin can help upregulate glyoxalase 1, which may be helpful with AGEs. It does this by activating the Nrf2 pathway.[ref]
- Lipedema: A metabolite of hesperidin is recommended by researchers for lipedema, but there aren’t clinical trials on it yet.[ref][ref]
- Flu season: Hesperidin has been shown in several cell studies to inhibit the replication of influenza A. However, there aren’t any clinical trials of hesperidin for the flu.[ref]
Detailed article on Nattokinase
A natural component of Japanese Natto, nattokinase is an enzyme that helps to break down blood clots. The full article is full of references and clinical trial data on nattokinase.
| Key Benefits | Who May Benefit | Who Should Use Caution |
|---|---|---|
| – Helps to break down clots | – Individuals with elevated fibrinogen | – People on blood thinners, talk with your doctor if on medications |

Cautions with Nattokinase:
Please be sure to talk with your doctor if you are already on any anticoagulant or heart-related medications before taking nattokinase. Additionally, nattokinase is derived from natto, which is fermented. It is possible that people with histamine-related issues could notice an increase in histamine from nattokinase.
