Safety guide · United States
FitLine is a product range, not one formula. Possible effects and precautions depend on the exact SKU, dose, caffeine, allergens, medications and individual health.
Popular US questions
Direct answers first. Product-specific labels and official terms remain the final authority.
Safety cannot be answered at brand level. FitLine includes powders, capsules, liquids and cosmetics with different ingredients and warnings. Evaluate the exact US SKU, labeled serving, caffeine, allergens, medicines and health conditions. Stop use and seek urgent care for a severe allergic or cardiovascular reaction.
Back to questions ↑Possible unwanted effects depend on the formula. Caffeinated products may cause restlessness, sleep disruption, tremor or palpitations. Powders and concentrated ingredients may cause nausea, bloating or bowel changes. Public reports do not establish frequency, and persistent symptoms require professional assessment.
Back to questions ↑Current structured data confirms 30 mg per stated daily portion for Activize Oxyplus and PowerCocktail, with caffeine carried into sets containing them. Matching ProShape Vanilla label data lists 3.4 mg per serving. Other products may require current-label confirmation rather than an assumption.
Back to questions ↑Do not assume every product is intended to be stacked. Combining products can duplicate vitamins, minerals, caffeine or other ingredients. Add totals across the full day, follow each package direction and ask a clinician or pharmacist when using medicines or managing a medical condition.
Back to questions ↑Do not extrapolate general adult directions to pregnancy or breastfeeding. Ingredient tolerance, caffeine limits and nutrient needs can change, and some multi-ingredient products may be unsuitable. Use only with advice from a qualified clinician who can review the exact current label and total diet.
Back to questions ↑Only use a product for a child when the current package explicitly supports the child’s age and provides age-specific directions. A “Junior” name is not permission to scale an adult serving. Check the full label and obtain pediatric guidance when the information is incomplete.
Back to questions ↑Potential interactions depend on ingredients, dose, health conditions and the medicine involved. A general website cannot screen them reliably. Bring the current label to a pharmacist or clinician, especially for cardiovascular, endocrine, kidney, liver or anticoagulant treatment and before surgery.
Back to questions ↑Dietary supplements generally are not approved by FDA before sale in the way prescription drugs are. Manufacturers and distributors remain responsible for safety, labeling and lawful claims. FDA registration, compliant manufacturing language or sale in the United States should not be described as product approval.

Selected FitLine powders disclose caffeine. Possible unwanted effects can include restlessness, sleep disruption, palpitations, tremor, headache or gastrointestinal discomfort, especially when combined with coffee, tea, energy drinks or pre-workout products.

Using several products together can duplicate nutrients. Add the amounts across supplements rather than assuming every product is intended to be stacked.
Review the complete Other Ingredients or INCI, not only the front label. Products may contain or be manufactured with milk, soy, fish or other relevant ingredients depending on the SKU and version.
Ask a qualified clinician or pharmacist before use when taking prescription medicines, managing cardiovascular, kidney, liver or endocrine conditions, or preparing for surgery. A product guide cannot reliably screen individual interactions.
Do not extrapolate adult directions to pregnancy, breastfeeding or children. Follow explicit package age restrictions and obtain professional guidance when the label does not clearly address the situation.
Powders containing fiber, concentrated vitamins, sweeteners or other ingredients can cause nausea, bloating or bowel changes in some users. Stop and reassess if symptoms are persistent or significant.
Quick answers
No. Caffeine varies by product. Some current listings disclose an exact amount; other products are topical cosmetics or do not identify caffeine in the accessible catalog text.
No. Natural origin does not guarantee safety, suitability or absence of interactions.
FDA generally does not approve dietary supplements or their labeling before sale. Manufacturers and distributors are responsible for safety and compliant labeling.
