The Standard Adult Serving
For all Vital Earth Minerals liquid products, the standard adult serving is 1 fluid ounce per day. The bottle cap is calibrated to hold exactly 1 fl oz — fill to the cap rim and drink directly, or mix with water or juice.
Most people take their serving once daily. It can be taken at any time of day — morning, midday, or evening. There is no strict requirement around timing, though some people prefer taking it in the morning alongside other supplements or with a meal.

How to Start: The Gradual Introduction Approach
Vital Earth Minerals recommends that new users start at one-quarter of the standard serving — approximately ¼ fl oz, or about 7.5 mL — for the first week, then build up gradually over one to two weeks to the full serving.
This gradual approach is recommended for two reasons:
- Adjustment period: When the body begins receiving trace minerals it may have been deficient in, some people experience a temporary adjustment period during the first few days — mild digestive changes, temporary fatigue, or similar mild responses. Starting at a reduced serving minimizes this.
- Individual variation: People respond differently. Some people find a half-serving is right for them long-term; others build to the full serving quickly. Starting low and building up lets you find your individual optimal amount.

Dosage for Children
Vital Earth Minerals liquid products are suitable for children when used as directed. The recommended serving for children is scaled by body weight:
| Body Weight | Daily Serving | Notes |

| 50–99 lbs | ½ fl oz (approx. 15 mL) | Start at half this amount for the first week |
| 100 lbs and over | 1 fl oz (full adult serving) | Start at ¼ fl oz for the first week |
As with adults, it is advisable to start at a reduced amount when introducing to children and build up gradually. Consult a qualified pediatric healthcare provider for guidance specific to your child’s situation.*

Combining Products
Many Vital Earth Minerals customers use multiple products simultaneously — for example, Mineral Blend as a daily foundation plus Super Multi for B vitamins and additional minerals. Products can be combined safely as directed. If combining multiple liquid products, the combined volume counts toward your daily serving — there is no need to take a full cap of each.
If you take prescription medications, consult your healthcare provider before starting any new supplement program, including fulvic minerals. See the Safety page for specific guidance on known interaction considerations.*
What to Expect When You Start
Most people begin noticing changes within the first two to four weeks of consistent use — though individual experiences vary widely and some people take longer. The changes people most commonly describe are not dramatic or sudden; they tend to be gradual and related to energy consistency, digestive comfort, and general wellbeing.*
Vital Earth Minerals makes no claims about specific outcomes. What we do say is that fulvic and humic minerals support the underlying mineral status and cellular processes that many aspects of daily functioning depend on — and that consistency matters more than dosage quantity.*
Frequently Asked Questions
Can I take more than 1 fl oz per day?
The standard serving of 1 fl oz per day is the recommended amount. Some people take more, particularly those who feel they have significant mineral deficiencies. However, more is not necessarily better — the goal is consistent daily mineral support, not high-dose loading. Consult a qualified healthcare professional for guidance specific to your situation. These statements have not been evaluated by the FDA.
Can I take it on an empty stomach?
Yes. Fulvic minerals can be taken with or without food. Some people prefer taking it with a meal to minimize any initial digestive adjustment during the starting phase. These statements have not been evaluated by the FDA.
Can I mix it with my other supplements?
Generally yes. However, because fulvic acid is a chelating agent, it can bind to other minerals and compounds. If you take prescription medications or have specific health concerns, consult your healthcare provider before mixing. The Safety page covers known interaction considerations.
