Timing Is Everything… Right?

The Truth About When to Take Your Supplements

“Does it really matter when you take your supplements?”

It’s one of the most common questions I’ve been asked throughout my time working in the world of dietary supplements, and for good reason. If you’re investing your hard-earned money into a supplement, you want to get the most out of it. 

The truth? Timing can absolutely influence absorption and effectiveness. But it is still just part of the equation. Before we dive in, it may be worth emphasizing a key principle: consistency often beats perfect timing. Even the best supplement won’t deliver results if you forget to take it. So while timing matters, the ultimate goal is to keep your routine memorable and practical.

Let’s break it all down by category.

Fat-soluble nutrients

A wide variety of nutrients, many of which might be in your medicine cabinet, are classified as fat-soluble, meaning they dissolve in fats and oils rather than water. Fat-soluble nutrients include heart-supportive Coenzyme Q10, antioxidant carotenoids (such as astaxanthin, lutein, and zeaxanthin), vital omega-3 fatty acids like EPA and DHA, as well as essential vitamins A, D, E, and K.* 

Best time to take: With a meal that contains fat

A good rule of thumb is to take fat-soluble nutrients with your “largest” meal of the day. Why? This meal is likely to include dietary fat, which helps these nutrients dissolve and become more available for absorption. Examples of good dietary fat include wild-caught salmon, raw seeds/nuts, or virgin olive oil. Dietary fat stimulates bile secretions, which act as a natural detergent, breaking fats into smaller droplets so they can be efficiently absorbed in the small intestine.

Supplement brands will sometimes include carrier oils (such as sunflower or palm oil) to aid in the absorption of a fat-soluble nutrient. While helpful, the amount of oil is often small and may not fully replace the benefit of taking the nutrient with a meal that contains fat.

Research highlight: In a controlled human trial, subjects who took vitamin D3 (like found in AzureWell’s Whole Food Multi-Vitamin) with a fat-containing meal had 32% higher blood levels compared to those who took it with a fat-free meal. (Hughes et al, Journal of the Academy of Nutrition and Dietetics, 2015)

Consideration: If you suffer from low bile production, such as after gallbladder removal, you may have greater difficulty absorbing fat-soluble nutrients. Consult with a qualified health professional to determine if taking digestive enzymes and/or digestive bitters might be a helpful addition.*

Water-soluble nutrients

In contrast to fat-soluble nutrients, water-soluble nutrients dissolve in water, which allows them to be quickly absorbed into the bloodstream. This group includes immune-supportive vitamin C, as well as all eight B vitamins (e.g. niacin, folate, B12), which play key roles in energy production and metabolism.* With the exception of B12, most water-soluble vitamins aren’t stored in the body, so consistent daily intake is important.

Pro Tip: Consider taking B vitamins in the morning to support energy and metabolism throughout the day.

In addition to these essential vitamins, other water-soluble forms of nutrients include creatine, glutathione, and single amino acids, like taurine.

Best time to take: Anytime

Because they don’t require fat for absorption, water-soluble nutrients can be taken with or without food. While water-soluble vitamins are usually well tolerated, some people can experience digestive discomfort, especially with isolated or synthetic forms, and may need to take them with food.

A “whole food” approach offers an alternative. For example, AzureWell’s Whole Food C Complex provides vitamin C from amla fruit — not synthetic ascorbic acid. This plant-based option provides natural cofactors that support both absorption and tolerance. This approach focuses on delivering nutrients in a more complete form, closer to how they’re found in nature, while remaining gentle to your digestion.

Minerals

Minerals can behave a bit differently. Most supplemental minerals (e.g. calcium, magnesium, zinc) require an acidic stomach environment to dissolve and be absorbed efficiently. 

Best time to take: After a meal (especially one with protein)

Consider taking minerals after consuming a meal rich in protein. This is typically when stomach acid is at its highest. Protein stimulates the production of hydrochloric acid (HCl), which breaks minerals down into charged ionic forms that can be absorbed.

A closer look at magnesium

The mineral I am most often asked about is magnesium, popularly referred to as the “master mineral” due to its involvement in hundreds of enzymatic processes. This includes energy production, bone health, as well as muscle and nerve function.*

It is important to note that many supplemental forms of magnesium are often poorly absorbed and may cause digestive discomfort and/or loose stool. To maximize absorption, especially when taking higher amounts, try splitting the dose and taking it after your two largest meals of the day.

The “chelation” advantage

Chelated minerals, which are simply bound to amino acids (e.g. magnesium bisglycinate), are often easier to absorb and gentler on the digestive system. In fact, chelated minerals do not rely as heavily on stomach acid for absorption and can typically be taken on an empty stomach if preferred. Consider AzureWell’s Magnesium G product, which provides magnesium chelated with glycine, with no additives or fillers.

Pro Tip: High-fiber supplements may lower the absorption of minerals, so avoid taking them at the same time. The same concept also applies to AzureWell’s IP6 product. Also, some minerals compete for absorption, such as iron and calcium, so it may be best to take them separately.

Probiotics

In addition to consuming healthy fermented foods like sourdough bread and sauerkraut, probiotic supplements can provide targeted strains of beneficial microbes to support a healthy gut.* There are countless probiotic supplements available and they often vary greatly based upon strain selection, dosage, and delivery systems, so be sure to consider the product’s “suggested use” before consuming.

Best time to take: with food (in most cases)

For many traditional strains, such as Lactobacillus and Bifidobacterium, research demonstrates that taking probiotics with food may improve their survival through stomach acid. (Wang et al. Gut Microbes. 2022). Food may act as a natural acid buffer, protecting the bacteria on its journey to the intestines.

Pro Tip: If you’re looking for a more resilient probiotic that can be taken anytime, consider spore-forming strains like Bacillus subtilis and the beneficial yeast Saccharomyces boulardii. In addition to being shelf-stable (with no refrigeration required), these strains are highly durable and less sensitive to timing, making them convenient to take whenever best fits your routine. (Tompkins et al. Beneficial microbes, 2011). 

Enzymes

Enzymes are important “tiny” proteins in the body that make chemical processes faster and more efficient. As we age, the body slows in enzyme production, which can weaken certain processes like digestion.* Furthermore, most food today is heavily processed and lacking natural enzymes, making supplementation a popular choice.

There are two main categories of enzymes in dietary supplements. Some are “digestive”, which help to break down the food we eat. Others are “systemic,” which support processes throughout the body. While digestive enzymes need to be taken with a meal to maximize food breakdown and nutrient absorption, systemic enzymes should be consumed on an empty stomach to maximize absorption into the bloodstream. For best results, take systemic enzymes at least an hour before or two hours after eating.

Digestive enzymes: Take with a meal

Systemic enzymes: Take on an empty stomach

Pro Tip: A variety of “systemic” enzymes are available in supplements. Consider Nattokinase to support circulatory health or Serratiopeptidase to support a healthy inflammatory response.*
