Determining Your Ideal Wellness Routine—Through Your Blood

The human blood system interacts with the entire body—organs, tissues and all. “It supplies nutrients and oxygen, removing CO2 and other waste products, and it’s also a medium through which all our tissues and cells communicate via a bewilderingly complex chemical cross-talk,” says Paul Clayton, a medical pharmacologist and fellow at the Institute of Food, Brain & Behaviour, affiliated with Oxford University. The most basic blood panels cover metabolic function, lipids (or cholesterols), iron, thyroid and, sometimes, vitamin D. But they can get far more granular and include a comprehensive thyroid, zinc, B vitamins and ferritin. If hormones are suspect, then Holey looks at a reproductive hormonal panel for any imbalances. Blood panels can also identify toxic exposures and markers for cellular function, which can give you an idea of your cell’s ability to repair damage, says Chika Okoli, a functional medicine physician at the New York City location of the Well, a wellness facility that consistently uses blood work.

“During Covid consumers became more conscious of their health,” says Lola Priego, founder and CEO of Base, an at-home diagnostic system that relies on blood and saliva testing. A physician reviews all results before uploading them to the Base app, and the Base medical advisory board oversees the algorithms giving users nutritional, supplemental and lifestyle suggestions. In addition to finding conditions like hypo- or hyperthyroidism, elevated cholesterol and diabetes, looking at blood data can help to address issues like sleep quality and chronic fatigue, Priego says. The clinical laboratory market experienced growth throughout the pandemic. Base, for example, launched and raised a $3.4 million round of funding during this time, while London-based blood-testing brand Thriva raised a $4.8 million extension to its series A funding in May 2020. “The so-called ‘lab on a chip’ technology is developing rapidly,” says Clayton, adding that Theranos, the failed blood-testing company, is an example of how badly things can go wrong. “It’s eventually going to become something like what Theranos promised but couldn’t deliver,” says Clayton. For the time being, most of these companies outsource to established labs to get the results.

The state of our blood can also affect our skin. Without healthy circulation and microcirculation, the skin, like any other organ, doesn’t function as well. “It leads to accelerated aging of the skin and reduced elasticity, hydration capacity and probably immune function,” says Clayton. Holey frequently looks to blood tests for guidance when troubleshooting a skin symptom. She says she sees correlations between anemia and perioral dermatitis or rosacea, while low vitamin D levels sometimes connect with psoriasis and eczema, and high cholesterol and poor digestion with breakouts or seborrheic dermatitis. “I am not an M.D., so it is never about diagnosing,” says Holey, who studied engineering and cosmetic chemistry. “If what I am seeing topically lines up with my hypothesis given what I see from labs, then I can better direct to the most appropriate M.D. or specialist.” She encourages her skin clients to keep up with annual blood work. “You can start to see trends or catch low or high levels from year to year,” says Holey. “It’s like starting a library of your health.”

In the practice of TCM, blood plays a critical role. “We are constantly thinking about how strong the quality of blood is and how well it moves throughout the body,” says Sandra Chiu, acupuncturist, herbalist and founder of Lanshin, a Chinese medicine clinic in Brooklyn. But the method by which blood is evaluated is radically different from Western medicine’s approach. “We often look at, or ‘read,’ the skin to ascertain the state of blood,” she adds. For example, says Chiu, in eczema when the skin is dry and itchy, that is considered excessive heat in the blood manifesting on the surface; when skin is dark red or almost violet, as is the case with rosacea or some types of cystic acne, that means there is significant stagnation. Looking at the blood, via the skin, helps guide Chiu’s treatment approach.

Getting the details of my own blood work served as a guide for me as well. After I submitted blood and saliva samples to Base, my results were transmitted a few weeks later via the company’s app, along with an invitation to set up a consultation to discuss them. Some of the information was unsurprising: My HbA1c (blood sugar) levels were elevated, which meant I should cut back on refined sugars and carbohydrates, and my cortisol levels were wreaking havoc on my sleep, so I needed to reduce my stress levels, relax and meditate. Discovering that I was low on vitamin D—and learning how to improve that score with exercise, diet and supplements—did pinpoint a possible source of fatigue, brain fog and dry, patchy skin. While blood work can certainly offer helpful data in regard to our health and beauty choices, Holey cautions against letting it be our only guide. “Take it all with a grain of salt,” she says. “What we have really learned is that blood work is just one piece of the puzzle.”
